1.18	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.17	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.16	07-Jan-2002	thorpej	branches: 1.16.2; Overhaul of the ISA autoconfiguration code to support direct configuration of devices logically attached to the ISA bus: * Change the isa_attach_args to have arrays of io, mem, irq, drq resources. * Add a "pnpnames" and a linked list of "pnpcompatnames" to the isa_attach_args. If either of these members are non-NULL, direct configuration of the bus is being performed. Add an ISA_DIRECT_CONFIG() macro to test for this. * Drivers are not allowed to modify the isa_attach_args unless direct configuration is not being performed and the probe fucntion is returning success. * Adapt device drivers -- currently, all driver probe routines return "no match" if ISA_DIRECT_CONFIG() evaluates to true.
1.15	15-Nov-2001	lukem	add RCSID
1.14	24-Sep-2000	jdolecek	branches: 1.14.2; 1.14.6; use new generic bootverbose instead of local definition

1.10	09-Mar-1998	mikel	print proper invalid IRQ, from Heiko Rupp in PR 5128
1.9	20-Oct-1997	thorpej	Don't panic if we fail to remap i/o or mem space in the attach function. Instead, print a diagnostic and return. (Some drivers do this already.) Also, normalize the diagnostic message, and fix some places where the printfs were getting ugly.
1.8	04-Oct-1997	thorpej	Fix some license confusion.
1.7	04-Oct-1997	thorpej	Copyright assigned to The NetBSD Foundation.
1.6	27-Aug-1997	bouyer	Merge scsipi branch in the mainline. This add support for ATAPI devices (currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2 busses to which devices can attach (scsibus and atapibus). This needed to change some include files and structure names in the low level scsi drivers.
1.5	21-Oct-1996	thorpej	branches: 1.5.8; 1.5.10; New bus.h implementation/interface: - No more distinction between i/o-mapped and memory-mapped devices. It's all "bus space" now, and space tags differentiate the space with finer grain than the bus chipset tag. - Add memory barrier methods. - Implement space alloc/free methods. - Implement region read/write methods (like memcpy to/from bus space). This interface provides a better abstraction for dealing with machine-independent chipset drivers.
1.4	13-Oct-1996	christos	backout previous kprintf changes
1.3	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf

1.12.14.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.27	29-Jan-1995	mycroft	Clean up deleted files.
1.26	13-Jan-1995	mycroft	Simplify some sanity checks.
1.25	07-Jan-1995	mycroft	Don't print line numbers in most of the diagnostics.
1.24	07-Jan-1995	mycroft	Cosmetic changes, to look more like the new esp.c will.
1.23	03-Jan-1995	mycroft	Add interrupt sharing types.
1.22	31-Dec-1994	mycroft	Fix non-serious typo.
1.21	28-Dec-1994	mycroft	Numerous changes. Many bugs fixed, better autoconfig, a few new features.
1.20	30-Nov-1994	mycroft	Don't stall the queue on CHECK SENSE if we get a reselect while selecting.
1.19	29-Nov-1994	mycroft	Fix a null pointer reference.

1.17	29-Nov-1994	mycroft	For consistency...
1.16	29-Nov-1994	mycroft	Handle BUS FREE phase a little differently, to get better error detection. Other cleanup.
1.15	29-Nov-1994	mycroft	Disable debugging breakpoints by default.
1.14	29-Nov-1994	mycroft	* Redo most of the message and phase state machines. Multiple pending message outs should now work correctly (including retransmissions). Multiple messages ins should be more efficient. Missing REQ after reselection phase should now (correctly) cause a wait with ENREQINIT set. * Abstract out the reselection out sequence, and use it directly to get sense info. (This is somewhat faster than the generic done/sched sequence.) * If there are no ACBs available, wait interruptibly for one. * Leave the interrupt registers alone during message in/out; just watch for phase change. Don't (incorrectly) reenable interrupts during data in/out; defer that to aicintr(). * Handle command pointer per SCSI 2 spec. * Other minor coding improvements.
1.13	18-Nov-1994	mycroft	Convert port, IRQ, and DRQ numbers to ints.

1.1	09-Jan-1994	cgd	LBL /dev/audio and soundblaster drivers, as ported by brad@fcr.com. both should work with both old- and new-config i386 trees. Some notes: bsd_audio.c has dependencies on the soundblaster. This should be fixed, so that it can be used for the PC speaker (when its driver has been modified), as well. sb.c needs some cleanup, and will have sections trimmed, eventually (when new config becomse standard for i386). additionally, the SBPro support needs some cleanup.
1.3	17-Apr-1995	cgd	useless, as of the new sound drivers.

1.11	20-Dec-1993	davidb	Fixed bug where with two or more SCSI controllers of the same type, you could not have devices at the same ID on each bus. This patch not directly applicable to magnum branch, which is using Julian's new SCSI code.
1.10	20-Dec-1993	mycroft	Canonicalize all #includes, and add pio.h where appropriate.
1.9	07-Dec-1993	deraadt	__386BSD__ -> __NetBSD__

1.102	04-Sep-2006	perry	switch to a common clock.c
1.101	04-Sep-2006	perry	The i386 and amd64 versions are now identical. They'll get moved to arch/x86 soon. Ultimately the functionality should be split into different files for i8254, mc146818 and pcppi.
1.100	04-Sep-2006	perry	The amd64 and i386 versions of this file both got some variables renamed to avoid shadowing. The amd64 names are a bit easier to understand, so switch to them here.
1.99	04-Sep-2006	perry	Fix static function declarations.
1.98	03-Sep-2006	perry	remove the "clkintr_pending" stuff. The variable was used but never set. Kardel says it is a remnant from the freebsd code he ported, and may be safely discarded.
1.97	03-Sep-2006	perry	add an #ifndef __x86_64__ around #include "mca.h" reduces diffs with the amd64 port We'll soon merge these entirely
1.96	03-Sep-2006	perry	fix declaration of tickle_tc() -> tickle_tc(void)
1.95	03-Sep-2006	christos	make this compile again (thanks gdamore)
1.94	03-Sep-2006	gdamore	Convert i386 to use common TODR code. Not tested, but Christos says he'll test it for me right now. :-)
1.93	09-Jul-2006	christos	Fix a bit of debugging code (from Arnaud Lacombe)
1.92	07-Jun-2006	kardel	branches: 1.92.2; convert to timecounters (from branch simonb-timecounters)
1.91	11-Mar-2006	kleink	branches: 1.91.4; Provide BCD<->binary conversion in libkern and turn <dev/clock_subr.h>'s FROMBCD()/TOBCD() macros into wrappers around it, resulting in both smaller code footprint and elimination of possible issues due to multiple evaluation of macro arguments. Suggested by Simon Burge and Anders Gavare on tech-kern.
1.90	19-Feb-2006	thorpej	branches: 1.90.2; 1.90.4; Use aprint_*().
1.89	24-Dec-2005	perry	branches: 1.89.2; 1.89.4; 1.89.6; Remove leading __ from __(const\|inline\|signed\|volatile) -- it is obsolete.
1.88	11-Dec-2005	christos	merge ktrace-lwp.
1.87	29-May-2005	christos	branches: 1.87.2; avoid variable shadowing.
1.86	03-Feb-2005	perry	move a prototype back inside an #ifdef -- my GENERIC kernels worked fine with it in the new place, but compiling another kernel found that it wasn't a good idea.
1.85	03-Feb-2005	perry	de-__P, partially ANSIfy
1.84	03-Jul-2004	yamt	branches: 1.84.4; 1.84.6; i8254_initclocks: fix an integer overflow problem in rev.1.83. a patch provided by FUKAUMI Naoki. PR/26152.
1.83	01-Jul-2004	yamt	{i8254,lapic}_initclocks: try to be more precise using fixtick.

1.78	05-Feb-2003	nakayama	Share i386/tsc_microtime.c with alpha and sparc64 as kern_microtime.c. (approved by martin)
1.77	10-Dec-2002	perry	Change from a hardcoded sanity check date that has to be updated by hand every few years to code that uses the automatically generated time value from config_time.h Fixes an ancient XXX in the code.
1.76	03-Dec-2002	kenh	The day-of-week register in the MC146818 has the value 1-7, but clock_secs_to_ymdhms() returns dt_wday with a range of 0-6. Make sure the DOW register has the correct range.
1.75	22-Nov-2002	fvdl	New interrupt code. The basic idea behind it is to hide the differences in interrupt controllers in struct pic, and try to keep as much common code as possible. At the lowest (asm) level, this is done with CPP macros. The main structure is now struct intrsource, describing an established interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic). For quick masking, there may be a maximum of 32 sources per CPU. Sources can be assigned to any CPU in the MP case, though currently they all go to the boot CPU.
1.74	02-Oct-2002	thorpej	Tidy up CFATTACH_DECL() formatting.
1.73	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.72	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.71	13-Aug-2002	thorpej	No need for two copies of the i8253 register definitions. Remove the i386-specific copy, and adjust its users to add in the timer i/o base as necessary.
1.70	01-Jan-2002	perry	branches: 1.70.8; boost up default times for when clocks are insane (as we do every few years.)
1.69	15-Nov-2001	lukem	add RCSID
1.68	03-Nov-2001	jdolecek	Don't print any warning if the time base was not provided (i.e. given as zero). Fixes port-i386/1413 by David Carrel.
1.67	23-Apr-2001	jdolecek	branches: 1.67.2; 1.67.6; Move the inclusion of 'mca.h' so that it doesn't depend on pcppi. The clock interrupts are properly reset on PS/2 now. Handle the slighly different PS/2 CMOS layout and get/set century byte as appropriate. The check for valid CMOS CRC checksum is not implemented yet; I don't currently know algorithm they use. The info about PS/2 CMOS was taken from the Padgett Peterson's x86/MSDOS Interrupt List, release 60.
1.66	12-Mar-2001	wiz	Fix typo in comment reported by Yuji Yamano in kern/12391.
1.65	11-May-2000	jdolecek	branches: 1.65.6; Add i386-specific part of MicroChannel Architecture bus support, as found in some older IBM PS/2 machines. This code is based upon work by Scott D. Telford, with some minor bits in arch/i386/mca/mca_machdep.c taken from FreeBSD. XXX this is still very experimental and development version; use at your XXX own risk
1.64	03-May-2000	mycroft	Adjust asm statement for newer GCCs.
1.63	02-Feb-2000	minoura	branches: 1.63.2; Take care of National Geode (Cyrix MediaGX) built-in clock module bug. Patch supplied by INOUE Yoshinari <pf5y-inue@asahi-net.or.jp>, kern/8654.
1.62	06-Nov-1999	enami	branches: 1.62.2; - Export initrtclock(). - Call it from apm_resume(). This fixes timer problem on some laptop after hybernation (PR#4808). Reviewd by: fvdl@netbsd.org
1.61	29-Mar-1999	mycroft	branches: 1.61.2; 1.61.8; 1.61.10; 1.61.12; Recalculate delaytab[]. We need to round up in case we were on the edge of a tick and the hardware mysteriously responds fast enough that the delay ends up being 1 tick short. An unlikely event, but just in case anything actually relies on this...
1.60	29-Mar-1999	mycroft	delay(): For small values of n, use a fixed lookup table. Also use rtclock_tval as the limit, since this is what we actually programmed the chip for.
1.59	13-Feb-1999	christos	noise reduction.
1.58	07-Feb-1999	drochner	use mi data conversion functions, simplify inittodr() and resettodr()
1.57	07-Feb-1999	drochner	put all century related code into an own function clock_expandyear(), touch the CMOS century byte only if the CMOS contents passes a checksum test which qualifies it as "known compliant"
1.56	18-Jan-1999	drochner	Be more cautious about writing to the CMOS century byte. Update it only if it contained a "19" before. There are machines (in particular PS/2 descendants) which have a checksum at this place. Introduce a patchable kernel variable "rtc_update_century" to modify the behaviour: 1="always update" (for testing and if one wants to set the clock back) or -1="never touch".
1.55	13-Oct-1998	perry	Fix a stupid bug -- an if that was supposed to be nested but wasn't.
1.54	12-Oct-1998	perry	1) Change "dectohexdec" and "hexdectodec" to "bintobcd" and "bcdtobin". The old names were bogus. 2) Make the code grok the NVRAM's century field. This code is, to say the least, poorly tested. It should make NetBSD play nicer with other OSes that care about the century field, however.
1.53	06-Oct-1998	perry	Fix a potential Y2K bug on some clock chips: we were loading invalid BCD into the year field of the RTC in years > 1999. It seems to have worked just fine on my old broken down test machine, but apparently some others actually get hurt. Suckage. We now make sure that we load valid BCD. Other ports should check for variations on this theme.
1.52	15-Aug-1998	mycroft	Make copyright notices with my name consistent.
1.51	05-Aug-1998	perry	bzero->memset, bcopy->memcpy
1.50	05-Aug-1998	perry	Fix a problem first noticed by a user with a screwed up real time clock past the End of Time. If time_t is 32 bits, then the "End of Time" is Jan 18/19 2038 (depending on time zone). This code copes with RTC's past the end of time if time_t is an int32 or less. It just forces the time back to 2037. This will let users with screwed up clocks to at least boot and function long enough to set their clocks to something sane. This kludge is conditioned on an if (sizeof(time_t) <= sizeof(int32_t)) which will automatically optimize the code out once we switch time_t to a 64 bit quantity, which should happen well before 2037. Patch based on code from Michael C. Richardson, with help from Allen Briggs who pointed out a fencepost error.
1.49	27-Jun-1998	perry	Tweak more.
1.48	27-Jun-1998	perry	Oops. fix typo.
1.47	27-Jun-1998	perry	Boost base year to 1995. 1985 was over 12 years ago.
1.46	16-Apr-1998	drochner	Make sysbeep() use dev/isa/pcppi. (sysbeep0 at pcppi?) Remove findcpuspeed() - it's useless and was commented out for a while.
1.45	05-Feb-1998	drochner	Allow DELAY() to be called anytime: -don't enable interrupts at the end of gettick(), restore the previous state instead -start timer/counter 0 from delay() if necessary -comment out "findcpuspeed()", it would clobber the timer again, and it is unused anyway
1.44	13-Feb-1997	jonathan	branches: 1.44.8; Import Dennis Ferguson's i386 clock change request from PR 2785: * Add table-driven assembly-coded microtime(). * add boot-time computation of the interpolation table, allowing the hand-coded microtime() to work with locally-tuned nonstandard values of HZ or TIMER_FREQ. * delete old C version of microtime().
1.43	15-Jan-1997	perry	branches: 1.43.4; Eliminate obsolete TIMEZONE and DST options. Eliminate obsolete global kernel variable "struct timezone tz" Add RTC_OFFSET option Add global kernel variable rtc_offset, which is initialized by RTC_OFFSET at kernel compile time. on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many minutes west (east) of GMT the hardware RTC runs. Defaults to 0. Places where tz variable was used to indicate this in the past have been replaced with rtc_offset. Add sysctl interface to rtc_offset. Kill obsolete DST_* macros in sys/time.h gettimeofday now always returns zeroed timezone if zone is requested. settimeofday now ignores and logs attempts to set non-existant kernel timezone.

1.33	28-Jun-1995	cgd	note that most of dev/ic's contents have changed names
1.32	26-Jun-1995	cgd	check CMOS time against base time, for sanity. if CMOS time invalid, warn user and user base time. if base time < 1985, warn the user. if base time 5 or more years different than clock time, warn user, and if it's base time that's greater, use it. (The latter case is handy if one has a machine in which the CMOS battery is dead... I do.)
1.31	04-May-1995	cgd	use the machine-independent definitions for the mc146818. wrap the various uses of the chip (including the uses of the NVRAM on it) around the new defintions, structures, and functions specified in the header.
1.30	17-Apr-1995	cgd	clean up several ISA device interfaces: autoconfiguration, header inclusion, and interrupt configuration. more work still needs to be done, but it's getting better...

1.9	27-Jun-1993	andrew	ANSIfications.
1.8	15-Jun-1993	mycroft	Move definitions of TIMER_FREQ to timerreg.h, and fix value of CF for DELAY().
1.7	06-Jun-1993	cgd	incorporate Bruce Evans' interrupt changes, as hacked by Rod grimes, for patchkit patch 158. it appears to work well.
1.6	22-May-1993	cgd	add rcsids to everything and clean up headers

1.13.2.22	08-Feb-1994	mycroft	Don't try to clear the diag register in NVRAM; it's used for other purposes by some BIOSes, and mysterious lossage results.
1.13.2.21	16-Dec-1993	davidb	Moved RTC code from inittodr() to readtodr(). inittodr() now does something sensible with the time passed to it.
1.13.2.20	08-Nov-1993	mycroft	Correct a panic message to display the name of the right function.
1.13.2.19	29-Oct-1993	mycroft	delay(): Don't overflow if the value is small.
1.13.2.18	27-Oct-1993	mycroft	Use a null interrupt routine between timerattach() and cpu_initclocks(), to avoid calling hardclock(), but still allow the timer to be running without getting `stray interrupt' messages.
1.13.2.17	26-Oct-1993	mycroft	Use fixed I/O address for nvram(). Rearrange clockattach() and ) cpu_initclocks() to initialize interrupt handler early. Use a real spin loop in spinwait().
1.13.2.16	18-Oct-1993	mycroft	Add dummy setstateclockrate(). We don't need it.
1.13.2.15	17-Oct-1993	mycroft	Minor cleanup.
1.13.2.14	15-Oct-1993	mycroft	Fix some off-by-one errors reading and setting the timer chip.
1.13.2.13	15-Oct-1993	mycroft	Change `limit' variables to u_int as it generates smaller code.
1.13.2.12	12-Oct-1993	mycroft	Oops! Was installing the timer interrupt twice.
1.13.2.11	11-Oct-1993	mycroft	#include pio.h where needed, and remove cpufunc.h.
1.13.2.10	09-Oct-1993	mycroft	Slight rearrangement.

1.13.2.5	06-Oct-1993	mycroft	Change attach message.
1.13.2.4	30-Sep-1993	mycroft	Change some uses of IRQUNK to IRQNONE. #include isa.h and icu.h.
1.13.2.3	30-Sep-1993	mycroft	clock.c: Remove unnecessary casts. com.c: Update for new config. Add bis() and bic() macros like BSDI's. Add comspeed() and tiocm_xxx2mcr() from BSDI. comreg.h: Add COM_FREQ, COM_TOLERANCE, and COM_NPORTS. fd.c: Remove casts and clean up fdioctl(). [lm]ms.c: Add necessary gunk to [lm]ms_softc and remove casts.
1.13.2.2	24-Sep-1993	mycroft	clock.c: Finish conversion. Make rtcput() work if VRT bit not set. Speed up time conversion in delay(). fd.c: Minor changes to autoconfig. Use dv_parent rather than storing another pointer to the fdc_softc in each fd_softc. Change disk label stuff for our kernel. icu.s: Make splx() and splnone() return previous cpl for now. isa.c: Minor autoconfig changes. isa.h: rtcin() is now nvram() and is declare in nvram.h. Make isaphysmem a caddr_t. pccons.c: XXXX: Maybe we should insist they open /dev/io now. timerreg.h: #define TIMER_NPORTS. wd.c: Delete unused wdnoreloc() and wddospart(), and use remaining two bits in unit number. struct disk --> struct wd_softc. struct board --> struct wdc_softc. Still needs much work.

1.61.8.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.61.2.2	27-Jun-2000	he	Pull up revision 1.62 (via patch, requested by mjl): Reinitialize clock after hibernation, something which seems to be required on some laptops. Fixes PR#4808.
1.61.2.1	04-Feb-2000	he	Pull up revision 1.63 (requested by minoura): Detect and handle National Geode (Cyrix MediaGX) built-in clock module bug. Fixes PR#8654.
1.62.2.2	06-Nov-1999	enami	- Export initrtclock(). - Call it from apm_resume(). This fixes timer problem on some laptop after hybernation (PR#4808). Reviewd by: fvdl@netbsd.org
1.62.2.1	06-Nov-1999	enami	file clock.c was added on branch comdex-fall-1999 on 1999-11-06 01:14:02 +0000
1.63.2.9	19-Aug-2002	sommerfeld	merged with -current as of today. rearranged gdt init to deal with KVM86 changes; however, KVM86 has no chance of working yet; good thing it's not part of GENERIC
1.63.2.8	28-Jan-2002	sommerfeld	Yet Another mergeup with -current.
1.63.2.7	29-Dec-2001	sommerfeld	Yet another mergeup. New work: - Frank van der Linden's tlb shootdown fix. Mainline functionality merged: - IrDA - Kernel RCSID's - Transmeta CPU support - ACPI - XMM register access through procfs
1.63.2.6	27-May-2001	sommerfeld	Call tsc_microset() on each cpu early in boot, so that microtime() doesn't generate spurious crud the first time it's invoked.
1.63.2.5	26-May-2001	sommerfeld	Implement MP-synchronzed microtime(), based on Jason Thorpe's port of Dave Mills's cycle-counter-based microtime. XXX We need to figure out how to deal with processors where the cycle counter speed varies. We don't have a whole lot of alternatives; we could only use this on multiprocessors, which are less likely to throttle the clock to save power. The local apic timer runs at a fixed frequency, but it's count-down-to-zero, not the count-up-forever type of timer which the Mills code expects. This also does not solve the problem of microtime on 486-based multiprocessors..
1.63.2.4	30-Apr-2001	sommerfeld	Merge sommerfeld_i386mp_1 branch with -current as of today. GENERIC.MP kernel boots and runs multiuser on my ABIT BP6
1.63.2.3	10-Jan-2001	sommerfeld	Significant rewrite of slave CPU attach and initialization, centering on identifycpu() and spreading outward. Separate feature probes (cpuid invocation), which runs on the cpu being attached, from the display of this information, which runs on the boot cpu; remove some of the probe code from locore as it doesn't need to run that early. We now spin up secondary cpu's during cpu_attach, have them do a cpu feature probe, and then have them spin waiting for a "go" signal. We no longer pay attention to the cpu signature and cpuid features reported by the MP BIOS since those are known to be truncated for at least some bioses. We now do npx initialization (including FDIV bug detection) on all cpus. XXX Change some of the cyrix bug workarounds to fit the new identifycpu() system; this is untested.
1.63.2.2	25-Jun-2000	sommerfeld	Merge up to just-post-1.5 -current
1.63.2.1	20-Feb-2000	sommerfeld	Rename some functions to allow local apic to also be used for DELAY

1.11	12-Jul-1993	mycroft	Change tty code to use clist interface, but with ring buffer implementation. Also, fix a couple of bugs in tty.c and pccons.c, and some gross kluginess in the hp300 stuff.
1.10	07-Jul-1993	deraadt	pccons.c now dynamically allocates it's "struct tty" cons.c's "struct tty *cn_tty" wasn't used by any of the kernel, and goes away.

1.3	03-Jul-1993	cgd	Unless INTR_DEBUG is set, don't report all of the "random" event types. also, unless INTR_DEBUG is set, make the internal branch labels for the interrupt code be local labels, so profiling works OK.
1.2	27-Jun-1993	andrew	Replace SHOW_A_LOT_NOT with a more meaningful commented-out SHOW_A_LOT.
1.1	06-Jun-1993	cgd	incorporate Bruce Evans' interrupt changes, as hacked by Rod grimes, for patchkit patch 158. it appears to work well.
1.4.2.3	11-Nov-1993	mycroft	Make the rest of BDB handling #ifdef BDB. Maybe some day the rest of the world will see this debugger.

1.6	07-Jan-1995	mycroft	Actually, do the ID reset in elink_reset().
1.5	06-Jan-1995	mycroft	Do the reset in the individual drivers, not in elink_idseq().
1.4	03-Jan-1995	hpeyerl	This is correct according to the docs on both cards. Doesn't seem to make any difference to the known problems though.
1.3	27-Oct-1994	cgd	new RCS ID format.
1.2	16-Feb-1994	mycroft	Add copyright notices.

1.133	07-Apr-2000	thorpej	Use dev/isa/fd.c.
1.132	23-Mar-2000	thorpej	New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.
1.131	07-Feb-2000	thorpej	branches: 1.131.2; Add a new function call to the ISA DMA API: isa_dmamaxsize(), which returns the maximum transfer size for the specified DMA channel. Make all clients of ISA DMA use this call to determine their maximum transfer size.
1.130	07-Feb-2000	thorpej	Fix a bug in disksort_*() which caused non-optimal ordering when multiple active partitions were on a single spindle. Add a b_rawblkno member to struct buf which contains the non-partition-relative block number to sort by.
1.129	21-Jan-2000	thorpej	Update for sys/buf.h/disksort_*() changes.
1.128	24-Mar-1999	mrg	branches: 1.128.8; 1.128.14; completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.127	28-Feb-1999	explorer	Update to slightly altered rnd_attach_source() api
1.126	22-Feb-1999	mycroft	Use DMAMODE_DEMAND. Not tested, but presumed to work.

1.120	03-May-1998	drochner	Set console to polling mode before calling cngetc().
1.119	22-Mar-1998	drochner	switch to non-BROKEN_INDIRECT_CONFIG
1.118	10-Feb-1998	mrg	- add defopt's for UVM, UVMHIST and PMAP_NEW. - remove unnecessary UVMHIST_DECL's.
1.117	06-Feb-1998	mrg	add the i386 MD portions for UVM.
1.116	15-Jan-1998	thorpej	Kludge around i/o port overlap w/ the "wdc" driver.

1.114	16-Dec-1997	mikel	fix format string in FD_DEBUG printf(); from Eric Haszlakiewicz in PR 4692
1.113	20-Oct-1997	thorpej	Don't panic if we fail to remap i/o or mem space in the attach function. Instead, print a diagnostic and return. (Some drivers do this already.) Also, normalize the diagnostic message, and fix some places where the printfs were getting ugly.
1.112	19-Oct-1997	thorpej	Make sure the i/o and/or mem addresses aren't wildcarded (i.e. -1) before using the address in a bus_space_map() call.
1.111	13-Oct-1997	explorer	o Make usage of /dev/random dependant on pseudo-device rnd # /dev/random and in-kernel generator in config files. o Add declaration to all architectures. o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include that this code is derived in part from Ted Tyso's linux code.
1.110	10-Oct-1997	explorer	Add hooks to insert timing info into the random system
1.109	07-Sep-1997	mycroft	GC a bunch of NEWCONFIG stuff.
1.108	17-Jul-1997	jtk	branches: 1.108.2; use locator defines in "locators.h" to index cf_loc[] still to be done and/or decided not to be done: replace all *UNK uses in isa code with the native names from locators.h
1.107	23-Jun-1997	fvdl	Turn some bus_space_write_2s back to bus_space_write1s, like they should be. Seemingly leftover from bus_io -> bus_space transition. Fixes PR 3780, from Thorsten Frueauf
1.106	06-Jun-1997	thorpej	Pull thorpej-bus-dma branch into mainline.
1.105	15-Mar-1997	thorpej	branches: 1.105.2; Add a mountroothook that prompts the operator to insert a file system floppy, a'la the SPARC port.
1.104	09-Jan-1997	mycroft	s/soft error/soft error (corrected)/, to avoid confusion.
1.103	20-Dec-1996	jtk	repair fdopen() to allow multiple opens at same density (was broken with fdformat)
1.102	01-Dec-1996	jonathan	Fix #ifdef DEBUG prinf() lint: bp->b_bcount is long, not int.
1.101	30-Nov-1996	jtk	tabstop corrections, thanks to Paul Kranenburg
1.100	29-Nov-1996	jtk	Add floppy formatting facility. i386 floppy controller code came from FreeBSD, as worked on by: jc@irbs.UUCP (John Capo) vak@zebub.msk.su (Serge Vakulenko) ache@astral.msk.su (Andrew A. Chernov) joerg_wunsch@uriah.sax.de (Joerg Wunsch) dufault@hda.com (Peter Dufault) formatting ioctl interface is generalized to an MI interface. see fdc(4) and fdformat(1)
1.99	27-Nov-1996	thorpej	In fdcresult(), the loop that pulls status off the controller is treated as a "timeout", yet there's no specific delay in each iteration. Add a small delay (10 usec... pretty arbitrary) in each iteration. This fixes the "fdcresult: timeout" problems I've been having on my 200MHz P6.
1.98	13-Nov-1996	thorpej	Use bitmask_snprintf().
1.97	21-Oct-1996	thorpej	New bus.h implementation/interface: - No more distinction between i/o-mapped and memory-mapped devices. It's all "bus space" now, and space tags differentiate the space with finer grain than the bus chipset tag. - Add memory barrier methods. - Implement space alloc/free methods. - Implement region read/write methods (like memcpy to/from bus space). This interface provides a better abstraction for dealing with machine-independent chipset drivers.
1.96	13-Oct-1996	christos	backout previous kprintf changes
1.95	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.94	09-Oct-1996	explorer	turn off floppy motor (and light) even if the drive isn't found. This fixes some laptop indicator lights which would be stuck on after the probe
1.93	31-Aug-1996	mycroft	Oops; fix typo.
1.92	30-Aug-1996	mycroft	Make sure b_resid is always set before biodone().
1.91	27-Aug-1996	cgd	change cfprint_t type definition to take a const char , rather than a char , because that's what was really intended, and because if the print function modifies the string, various things could become unhappy (so the string should _not_ be modified).
1.90	12-May-1996	mycroft	branches: 1.90.4; Use intr.h.
1.89	12-May-1996	thorpej	Use <machine/bus.h> ... on the right track to making this an MI driver.
1.88	03-May-1996	christos	- Add missing prototypes. - Fix gcc warnings
1.87	11-Apr-1996	cgd	update for addition of a machine-dependent cookie as the first argument to isa_intr_{,dis}establish().
1.86	17-Mar-1996	thorpej	New device attachment scheme: - split softc size and match/attach out from cfdriver into a new struct cfattach. - new "attach" directive for files.*. May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.85	04-Mar-1996	mycroft	Update for changed DMA interface.
1.84	10-Feb-1996	thorpej	In fdcretry(), set the state to DOSEEK rather than SEEKCOMPLETE before retrying the operation. Fixes disk_unbusy() imbalance and really seems like the right thing to do in case it was the seek that failed. Takes care of PR #1985. Patch from John F. Woods <jfw@jfwhome.funhouse.com>
1.83	12-Jan-1996	thorpej	Balance calls to disk_busy() and disk_unbusy() properly to avoid dk_busy < 0 panics. Count seeks.
1.82	07-Jan-1996	thorpej	New generic disk framework. Highlights: - New metrics handling. Metrics are now kept in the new `struct disk'. Busy time is now stored as a timeval, and transfer count in bytes. - Storage for disklabels is now dynamically allocated, so that the size of the disk structure is not machine-dependent. - Several new functions for attaching and detaching disks, and handling metrics calculation. Old-style instrumentation is still supported in drivers that did it before. However, old-style instrumentation is being deprecated, and will go away once the userland utilities are updated for the new framework. For usage and architectural details, see the forthcoming disk(9) manual page.
1.81	28-Dec-1995	perry	fixed my own pr 1758 -- the floppy drive motor was not being turned off at halt time, especially if a floppy was mounted. Added a shutdown hook to turn off the motor. Per a request by mycroft, the cookie from the hook is saved in a new member I added to the fd_softc structure.
1.80	24-Dec-1995	mycroft	The IST_* and IPL_* constants are not bus-specific; don't treat them as such. Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.
1.79	21-Aug-1995	mycroft	Require drives 2 and 3 to be explicitly configured.
1.78	04-Jul-1995	mycroft	Make each disk and tape driver define its own read and write functions. Deprecate rawread() and rawwrite() completely. Remove d_strategy from cdevsw to force the abstraction barrier.
1.77	28-Jun-1995	cgd	note that most of dev/ic's contents have changed names
1.76	26-Jun-1995	cgd	DEBUG -> FD_DEBUG, so this thing doesn't spew when used with options DEBUG
1.75	26-Jun-1995	cgd	make dump stubs consistent. fix other piece of code to compile properly with DEBUG; used bogus variable.
1.74	04-May-1995	cgd	use the machine-independent definitions for the mc146818. wrap the various uses of the chip (including the uses of the NVRAM on it) around the new defintions, structures, and functions specified in the header.
1.73	17-Apr-1995	cgd	clean up several ISA device interfaces: autoconfiguration, header inclusion, and interrupt configuration. more work still needs to be done, but it's getting better...

1.10	10-May-1993	deraadt	Floppy drives now print the same information as wd controllers and scsi disks. See? fd0 at fdc0 slave 0: 1.44MB 80 cyl, 2 head, 18 sec Also, added a define for 720K disks, probably incorrect.. Note: the CMOS is used to find out what type the drive is.
1.9	04-May-1993	deraadt	support for making dev->id_alive be set, this is for iostat to find disk devices. wee bit of a kludge. sub-device attach() routines must now return 1 for successful attach(), 0 otherwise. Other bsd's do this too..

1.4	27-Jun-1993	andrew	Enable AUTO_EOI_1 by default; leave AUT_EOI_2 alone, even if it does seem to work very well, to avoid any potential troubal.
1.3	06-Jun-1993	cgd	incorporate Bruce Evans' interrupt changes, as hacked by Rod grimes, for patchkit patch 158. it appears to work well.

1.66	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.65	21-Sep-2001	fvdl	branches: 1.65.12; Make the newer gas happy by explicitly adding '*' to indirect calls, and matching mov extensions with register names.
1.64	14-Apr-2001	thorpej	branches: 1.64.2; 1.64.4; Generic soft interrupt implementation for NetBSD/i386. This could probably be tuned somewhat, but this is a stop-gap measure to hold us until Bill Sommerfeld's new interrupt code comes in from the MP branch.
1.63	02-Jul-2000	cgd	branches: 1.63.2; Kwality control: * put #includes of opt headers and headers to get protos used by net/netisr_dispatch.h in net/netisr.h (if !defined(_LOCORE)) (rather than in netisr_dispatch.h itself, and potentially nowhere, respectively). * require netisr.h to be included before netisr_dispatch.h. * minor additional cleanup of both netisr.h and netisr_dispatch.h. * clean up uses to remove now-unnecessary header file inclusions, and local prototypes of the fns. * convert netisr dispatch implementations which didn't use netisr_dispatch.h (pc532) to use it.
1.62	21-Feb-2000	erh	Define the DONETISR macro and use netisr_dispatch.h. This is to cut down on code duplication and to standardize the available NETISRs across all ports.
1.61	01-Jul-1999	thorpej	branches: 1.61.2; 1.61.10; Fix IPv6 software interrupt vector label.
1.60	28-Jun-1999	itojun	- Call ip6intr if INET6 is defined. - remove "need-flag" for mac68k esp driver, as it is not used in anywhere and conflicts with IPsec ESP header. This should be the only MD change in IPv6 support, except kernel config file. Very sorry if you have any compilation problem with it (I believe it is okay). If your favorite arch is not included in here, please add a call to ip6intr() from softintr handle.
1.59	26-Jan-1999	christos	branches: 1.59.4; 1.59.6; Add a missing _C_LABEL(). Now an ELF kernel builds (if one removes the -z flag from the ld line, in the Makefile)
1.58	01-Dec-1998	thorpej	Use _C_LABEL() to generate C labels in assembly code, don't prepend an underscore (_) directly. (XXX Except in a few places, where traditional CPP's macro evaluation semantics break things, so we test for __ELF__ directly in those places).

1.4	03-May-1993	glass	necesssary fix before the ISO, and NS stuff has even a prayer of working. Jolitz while garbage-collecting the ISO shit, also garbage collected the DO_NET(NETISR_XXX.... support for them. CCITT is still broken, i think because this snapshot's version is hosed.
1.3	09-Apr-1993	cgd	from Rodney W. Grimes (rgrimes@agora.rain.com) (patchkit patch 117): This patch adds the symbol names to icu.s that vmstat expects the interrupt counters to be called. It also adds code to config so that the names of the interrupts are written at the end of vectors.s so vmstat can report real device names. It also cleans up and enables the logging of stray interrupts. The counters for false interrupts are added but the fix for them is not (the fix I have is not done very good.) A false interrupt is when a device asserts it's interrupt signal, then removes it before the 8259 can latch it. This is the number one cause of stray IRQ7's and IRQ15's. Additional device probe information is now printed. This includes ending I/O address (many drivers do not return the correct value from a probe this still needs to be fixed), memory address and size, driver flags passed in by config.

The branch does not compile at all (due to the lack of ALTQ and some other source code). Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.
1.59.6.2	06-Jul-1999	itojun	KAME/NetBSD 1.4, SNAP kit 1999/07/05. NOTE: this branch is just for reference purposes (i.e. for taking cvs diff). do not touch anything on the branch. actual work must be done on HEAD branch.

Yuck. * * Revision 2.10 1993/10/23 04:07:12 davidg * increment output errors if the device times out (done via watchdog) * * Revision 2.9 1993/10/23 04:01:45 davidg * increment input error counter if a packet with a bad length is * detected. * * Revision 2.8 1993/10/15 10:59:56 davidg * increase maximum time to wait for transmit DMA to complete to 120us. * call ed_reset() if the time limit is reached instead of trying * to abort the remote DMA. * * Revision 2.7 1993/10/15 10:49:10 davidg * minor change to way the mbuf pointer temp variable is assigned in * ed_start (slightly improves code readability) * * Revision 2.6 93/10/02 01:12:20 davidg * use ETHER_ADDR_LEN in NE probe rather than '6'.
1.9	01-Oct-1993	davidg	* Revision 2.5 93/09/30 17:44:14 davidg * patch from vak@zebub.msk.su (Serge V.Vakulenko) to work around * a hardware bug in cheap WD clone boards where the PROM checksum * byte is always zero * * Revision 2.4 93/09/29 21:24:30 davidg * Added software NIC reset in NE probe to work around a problem * with some NE boards where the 8390 doesn't reset properly on * power-up. Remove initialization of IMR/ISR in the NE probe * because this is inherent in the reset. * * Revision 2.3 93/09/29 15:10:16 davidg * credit Charles Hannum * * Revision 2.2 93/09/29 13:23:25 davidg * added no multi-buffer override for 3c503 * * Revision 2.1 93/09/29 12:32:12 davidg * changed multi-buffer count for 16bit 3c503's from 5 to 2 after * noticing that the transmitter becomes idle because of so many * packets to load. * * Revision 2.0 93/09/29 00:00:19 davidg * many changes, rewrites, additions, etc. Now supports the * NE1000, NE2000, WD8003, WD8013, 3C503, 16bit 3C503, and * a variety of similar clones. 16bit 3c503 now does multi * transmit buffers. Nearly every part of the driver has * changed in some way since rev 1.30.
1.8	09-Sep-1993	davidg	branches: 1.8.2; As of this revision, all known bugs have been fixed. Some of the fixes include: 1) fixed 3c503 lock-up if the thinwire cable was disconnected at boot time 2) 8013EBT boards now work (quite well!) in 16bit/16k mode 3) ED_NO_DOUBLE_BUFFERING flag now works 4) slightly higer performance (about 3%) with 16bit WD/SMC boards 5) support for WD8013WC (10BaseT) boards Additionally, the probe code has been reorganized to be much cleaner. This revision of the driver is 1.25. The release notes have been updated as well.
1.7	04-Sep-1993	jtc	Include systm.h to get prototypes (and possibly inlines) of *max functions.
1.6	26-Aug-1993	cgd	0.9 "official" patch 001: (1) added support for ed1 in both generic kernels at: device ed1 at isa? port 0x250 net irq 9 iomem 0xd8000 vector edintr (2) brought if_ed.c up to DG's 1.19 rev.
1.5	03-Aug-1993	glass	with -Wall would bomb, on incomplete type 'selinfo'. bpfilter.h include moved down, and select.h included.
1.4	01-Aug-1993	mycroft	Add RCS identifiers (this time on the correct side of the branch), and incorporate recent changes in netbsd-0-9 branch.
1.3	28-Jul-1993	cgd	incorporate changes from 0-9-base to 0-9-ALPHA
1.2	12-Jul-1993	deraadt	branches: 1.2.2; moved bfdttach point to same place as other drivers, from greenman
1.1	03-Jul-1993	cgd	add support for David Greenman's "ed" driver.
1.2.2.6	25-Aug-1993	cgd	PATCH 1: add device ed1 so people with 3c503's can use them: > device ed1 at isa? port 0x250 net irq 9 iomem 0xd8000 vector edintr also, bring if_ed to DG's 1.19 rev.
1.2.2.5	27-Jul-1993	cgd	oops; forgot select.h
1.2.2.4	27-Jul-1993	cgd	most recent if_ed, with some important bug fixes
1.2.2.3	26-Jul-1993	cgd	Fixed logic problem which caused a bogus value to be written to the 3c503 asic register even if the board isn't a 3c503. This caused old 8003E's not to work because they ignore IO address bits >10bits and the 3c503 asic is located at +0x400....the offset was ignored by the 8003E and so the value was written to one of the NIC registers. The bug was discovered by Wolfgang Solfrank.
1.2.2.2	21-Jul-1993	cgd	from davidg: Added config file override for memory size and added flags to force 8bit or 16bit operation, and a flag to disable transmitter double buffering. See the updated "ed.relnotes" file for information about how to set the flags. This should be considered the first "production" release. It still needs a manual page, though.
1.2.2.1	20-Jul-1993	cgd	Fixed to allow iosiz config parameter to override what was (for jkh, incorrectly) probed. This allows you more flexibility in getting weird WD 80x3 clones to work.
1.8.2.21	10-Feb-1994	mycroft	Forgot to convert a couple of bits in the multicast code.

1.8.2.15	02-Feb-1994	mycroft	Change second arg of probe to self, and undo kluges to work around this stupid deficiency in autoconfig. Also, make the multicast code that nobody ever compiled actually compile.
1.8.2.14	02-Feb-1994	mycroft	A few nits.
1.8.2.13	02-Feb-1994	mycroft	Clean up cruft in multicast code.

1.12	27-Oct-1994	cgd	new RCS ID format.
1.11	23-Oct-1994	mycroft	Fix the packet length correction for buggy chips so that it actually works, and always use it (otherwise short packets could still be corrupted). Also produce a diagnostic message if DIAGNOSTIC, since it is a hardware bug. Add an ED_PAGE_SHIFT constant, and use it, to avoid GCC doing horrendous things with divides and multiplies.

1.65	04-Nov-1994	mycroft	Use kvtop() rather than address arithmetic in a couple of places.
1.64	04-Nov-1994	mycroft	Add a new function config_scan(), which just calls a particular function with each plausibly cfdata, ignoring the priority mechanism completely.

1.29	05-Nov-1993	cgd	note that use of splnone() is prolly bogus; splnone() itself is bogus, so it's use is. 8-)
1.28	28-Aug-1993	brezak	branches: 1.28.2; Add find_isadev() and have sysbeep() use common defines.
1.27	08-Aug-1993	cgd	there are some devices out there which use... NO I/O PORTS!
1.26	11-Jul-1993	mycroft	Make splimp = splnet \| spltty, and get rid of SLIP kluge for splnet and spltty.
1.25	07-Jul-1993	cgd	delete inclusion of rlist.h again. grr.

1.20	20-Jun-1993	deraadt	print "maddr 0xd0000 msize 65536" as "maddr 0xd0000-0xdffff" instead.
1.19	16-Jun-1993	mycroft	Fix typo.
1.18	16-Jun-1993	mycroft	Make sysbeep() take a frequency, not a timer count, and add constants BEEP_FREQ and BEEP_TIME which can be overridden in the config file.
1.17	15-Jun-1993	mycroft	Move definitions of TIMER_FREQ to timerreg.h, and fix value of CF for DELAY().
1.16	15-Jun-1993	mycroft	Clean up beep code a miniscule amount, add interrupt protection, and make multiple beeps generate a continuous tone.
1.15	06-Jun-1993	cgd	incorporate Bruce Evans' interrupt changes, as hacked by Rod grimes, for patchkit patch 158. it appears to work well.
1.14	28-May-1993	deraadt	1. It is now possible to build a kernel that does not have a pc0 device driver. 2. "press any key to reboot" reads the key from the console. 3. wddump() still needs a non-blocking getc() routine (or flush)
1.13	22-May-1993	cgd	add rcsids to everything and clean up headers
1.12	11-May-1993	deraadt	Whoops. One more 0x0ffff to expunge..
1.11	11-May-1993	deraadt	1. id_irq is a u_short 2. "irq ?" sets it to (u_short)-1 3. "irq #" sets it to (1<<#) 4. not specifying an interrupt sets it to 0. Until someone else comes up with a better scheme, that's the way it is. If you have a driver that turns the interrupt off, set it to ZERO. If, after calling XXprobe(), id_irq is still (u_short)-1, that is the same as if probe() failed.
1.10	08-May-1993	deraadt	multiple master controllers would probe tthe first one N times instead of once each. never mind not worth worrying about what i;m talking about.
1.9	07-May-1993	cgd	no irq == -1, or, actually, 0x0ffff (f*ing unsigned short...). this would break devices w/o interrupts (like lpa).
1.8	04-May-1993	deraadt	support for making dev->id_alive be set, this is for iostat to find disk devices. wee bit of a kludge. sub-device attach() routines must now return 1 for successful attach(), 0 otherwise. Other bsd's do this too..
1.7	04-May-1993	cgd	fixed loopback == nuke problem. This fix is probably not optimal, but it works.
1.6	15-Apr-1993	deraadt	ioconf changes, see previous cvs's that dumped core
1.5	09-Apr-1993	cgd	make printing of i/o addresses a bit prettier, and fix off-by-one error.
1.4	09-Apr-1993	cgd	from Rodney W. Grimes (rgrimes@agora.rain.com) (patchkit patch 117): This patch adds the symbol names to icu.s that vmstat expects the interrupt counters to be called. It also adds code to config so that the names of the interrupts are written at the end of vectors.s so vmstat can report real device names. It also cleans up and enables the logging of stray interrupts. The counters for false interrupts are added but the fix for them is not (the fix I have is not done very good.) A false interrupt is when a device asserts it's interrupt signal, then removes it before the 8259 can latch it. This is the number one cause of stray IRQ7's and IRQ15's. Additional device probe information is now printed. This includes ending I/O address (many drivers do not return the correct value from a probe this still needs to be fixed), memory address and size, driver flags passed in by config.
1.3	08-Apr-1993	deraadt	dmesg output at boottime now tries to print out information as soon as it is available. The output looks much more like Sunos.

1.60	27-Feb-2003	fvdl	Moved to x86/isa.
1.59	26-Feb-2003	fvdl	Adapt for i386/x86 change.
1.58	22-Nov-2002	fvdl	New interrupt code. The basic idea behind it is to hide the differences in interrupt controllers in struct pic, and try to keep as much common code as possible. At the lowest (asm) level, this is done with CPP macros. The main structure is now struct intrsource, describing an established interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic). For quick masking, there may be a maximum of 32 sources per CPU. Sources can be assigned to any CPU in the MP case, though currently they all go to the boot CPU.
1.57	05-Oct-2002	fvdl	Adjust callers to setgate() to match new extra parameter.
1.56	03-Oct-2002	fvdl	Make shared IRQs for the normal PIC case work again as they did before the MP merge (i.e. treat them as having the lowest level of all registered handlers in the chain for the IRQ).
1.55	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.54	18-Jun-2002	tshiozak	add MD support for ACPI sleep/wakeup.

1.46	11-May-2000	jdolecek	branches: 1.46.2; Add i386-specific part of MicroChannel Architecture bus support, as found in some older IBM PS/2 machines. This code is based upon work by Scott D. Telford, with some minor bits in arch/i386/mca/mca_machdep.c taken from FreeBSD. XXX this is still very experimental and development version; use at your XXX own risk
1.45	12-Nov-1999	drochner	branches: 1.45.2; make "i386_isa_chipset" globally visible so it can be used from outside the "isa" bus, attach "pnpbios" pseudo-bus if configured
1.44	25-Oct-1999	drochner	-mask interrupts w/o a handler -update PIC _after_ the interrupt handler is linked into the chain This fixes problems with dynamically installed interrupt handlers: Interrupts were enabled before the handler was installed under some circumstances (esp. on faster machines), leading to endless interrupt handling.
1.43	17-Sep-1999	thorpej	branches: 1.43.2; 1.43.4; 1.43.6; Centralize the declaration and clearing of `cold'.

1.34	03-Jun-1998	thorpej	Implement bounce buffers for mbufs.
1.33	03-Jun-1998	thorpej	Optimize the ISA DMA map load somewhat; don't traverse the buffer twice. Instead, just attempt to do a normal load first. If we exceed the bounce threshold or the number of segments, then we bounce the transfer.

1.31	26-Apr-1998	thorpej	Garbage-collect the DMA tag's "_cookie" member; it's not used for anything.

1.29	11-Feb-1998	thorpej	Use M_DMAMAP where appropriate.
1.28	04-Feb-1998	thorpej	Add offset and length parameters to bus_dmamap_sync(), used for specifiying partial syncs of a DMA mapping.
1.27	04-Feb-1998	thorpej	Change the last argument of bus_dmamap_sync() from bus_dmasync_op_t to int, and allow more than one synchronization operation to be specified in a single call. Dissallow mixing of PRE and POST operations.
1.26	04-Feb-1998	thorpej	Add dm_mapsize to bus_dmamap_t and rename BUS_DMAMEM_NOSYNC to BUS_DMA_COHERENT.
1.25	23-Jan-1998	mycroft	Some rearrangement of the startup code: * Move some of the memory bootstrapping and the DDB startup earlier. * Always put the IDT and the initial GDT and LDT in a separate page. * Various minor changes.
1.24	13-Nov-1997	mycroft	Some general cleanup: * Call gdt_init() earlier on. * Don't bother to check for TSS and LDT descriptors in verr_gdt(). * Nuke the sti special case for trace and breakpoint traps. * Move some variable declarations into more appropriate locations.
1.23	14-Oct-1997	thorpej	branches: 1.23.2; Pull down from marc-pcmcia branch: Implement new ISA interface functions: * isa_intr_alloc() - allocate an ISA IRQ * isa_mem_alloc() - allocate ISA memory space * isa_mem_free() - free ISA memory space
1.22	12-Jun-1997	thorpej	branches: 1.22.4; Nuke __VM_PMAP_HACK.
1.21	06-Jun-1997	thorpej	Pull thorpej-bus-dma branch into mainline.
1.20	19-May-1997	mycroft	Make sure intrtype[] is set. (Curious where this got lost...)
1.19	21-Mar-1997	mycroft	branches: 1.19.2; Add IPL_AUDIO.
1.18	28-Feb-1997	mycroft	Import interrupt priority changes from com patches: * Make it a strict hierarchy. (It was close anyway). * Add `serial' and rename `softtty' to `softserial'. * Make soft interrupts a bit less special-case.
1.17	28-Nov-1996	thorpej	branches: 1.17.6; In isa_attach_hook(), set a variable to indicate that an ISA bus has been attached to the system. If, by the time mainbus wants to attach an ISA an ISA has not yet been attached to the system, attempt to attach an ISA to mainbus.
1.16	20-Nov-1996	mycroft	Remove incomplete and unused `fast' vector code.

1.13	03-May-1996	christos	- Add missing prototypes. - Fix gcc warnings
1.12	11-Apr-1996	cgd	add an isa_attach_hook() function which currently does nothing, and update isa_intr_establish() and isa_intr_disestablish() to take an opaque cookie as their (new) first argument.
1.11	28-Feb-1996	cgd	make ISA bus match/attach and sub-device attachment machine-independent. (remove that code from this file.)
1.10	09-Feb-1996	mycroft	Enforce the hierarchy: imp > tty > net > bio, to cater to lame PC devices.
1.9	24-Dec-1995	mycroft	The IST_* and IPL_* constants are not bus-specific; don't treat them as such. Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.
1.8	09-Oct-1995	mycroft	Eliminate soft segment descriptors; instead use a functional interface for creating segment descriptors. Add the duplicate system call gate used by BSD/OS 2.0 executables. Prototype setsegment() and setgate(), and fix a bogon caught by this.
1.7	09-Aug-1995	mycroft	Fix oversight in previous change; spl*() must also block software interrupts.
1.6	04-Jul-1995	mycroft	Make hardware interrupts always block all software interrupts.
1.5	07-Jun-1995	cgd	make match/attach routines and cfdriver struct mi

1.19.2.1	13-May-1997	thorpej	Implement ISA-specific bus dma methods, and provide the bus dma tag to children via isa_attach_hook(). These bus dma methods are mostly wrappers around the generic i386 bus dma methods, but include support for DMA bounce buffers where required.
1.22.4.4	14-Oct-1997	thorpej	KNF.
1.22.4.3	29-Aug-1997	thorpej	Make isa_mem_alloc() and isa_mem_free() functions, not macros, so that IOM_* constants don't have to be in scope in order to call these. Also, fix a fencepost in isa_mem_alloc().

1.43.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.45.2.9	25-Jun-2002	sommerfeld	Resynch with -current.
1.45.2.8	29-Dec-2001	sommerfeld	Yet another mergeup. New work: - Frank van der Linden's tlb shootdown fix. Mainline functionality merged: - IrDA - Kernel RCSID's - Transmeta CPU support - ACPI - XMM register access through procfs
1.45.2.7	23-Jan-2001	thorpej	Sync with the trunk.
1.45.2.6	07-Jan-2001	sommerfeld	Snapshot of merge-in-progress with -current. [Not expected to build]. Catch up with the last N months worth of changes to -current.

1.45.2.4	21-Aug-2000	sommerfeld	Give systems reporting EISA interrupts in the mpbios tables a prayer of working.
1.45.2.3	07-Aug-2000	sommerfeld	Merge sommerfeld_i386mp_1 branch forward to 20000806 sources
1.45.2.2	25-Jun-2000	sommerfeld	Merge up to just-post-1.5 -current
1.45.2.1	20-Feb-2000	sommerfeld	Use level-based rather than mask-based interrupt masking. Compute interrupt masks differently. In isa_intr_establish, use the apic instead if we have an interrupt mapping.
1.46.2.1	22-Jun-2000	minoura	Sync w/ netbsd-1-5-base.

1.13	19-Mar-1999	cgd	Moved to arch/i386/include/isa_machdep.h,v
1.12	13-Aug-1998	thorpej	vm_offset_t -> {vaddr_t,paddr_t}, vm_size_t -> vsize_t
1.11	09-Jun-1998	thorpej	Add isa_dma{freeze,thaw}(), used to temporarily stop and then restart all ISA DMA. Needed by e.g. the SmartCard reader for Sharks.
1.10	09-Jun-1998	thorpej	Change the ISA DMA API to take an isa_chipset_tag_t rather than a struct device * corresponding to the ISA bus device. The ISA DMA controller driver functions have been renamed and now take a struct isa_dma_state *, and are called indirectly by machine-dependent code which provides the DMA state. These changes allow e.g. `ofisa' (the OpenFirmware configuration mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA DMA controller code.
1.9	03-Jun-1998	thorpej	Implement bounce buffers for mbufs.
1.8	14-Oct-1997	thorpej	Pull down from marc-pcmcia branch: Implement new ISA interface functions: * isa_intr_alloc() - allocate an ISA IRQ * isa_mem_alloc() - allocate ISA memory space * isa_mem_free() - free ISA memory space
1.7	06-Jun-1997	thorpej	branches: 1.7.4; Pull thorpej-bus-dma branch into mainline.
1.6	03-May-1996	christos	branches: 1.6.10; - Add missing prototypes. - Fix gcc warnings
1.5	11-Apr-1996	cgd	prototype MD functions for use by MI ISA code (isa_attach_hook(), isa_intr_{,dis}establish()) here. Make this file safely includable by <dev/isa/isavar.h> and by all of the places in the i386 that are currently including it, which means multiple inclusion protection and a few otherwise-extraneous 'forward' structure declarations. isa_intr_establish() and isa_intr_disestablish() now take as their first argument a machine-dependent cookie of type isa_chipset_tag_t, which is also defined here.
1.4	04-May-1995	cgd	use the machine-independent definitions for the mc146818. wrap the various uses of the chip (including the uses of the NVRAM on it) around the new defintions, structures, and functions specified in the header.
1.3	21-Apr-1995	mycroft	Clean up hole conversion functions a little.
1.2	21-Apr-1995	mycroft	Remove relocation of Crtat from locore.
1.1	17-Apr-1995	cgd	clean up several ISA device interfaces: autoconfiguration, header inclusion, and interrupt configuration. more work still needs to be done, but it's getting better...
1.6.10.2	18-May-1997	thorpej	Add an external declaration for the isa dma tag.
1.6.10.1	13-May-1997	thorpej	Implement ISA-specific bus dma methods, and provide the bus dma tag to children via isa_attach_hook(). These bus dma methods are mostly wrappers around the generic i386 bus dma methods, but include support for DMA bounce buffers where required.
1.7.4.3	29-Aug-1997	thorpej	Make isa_mem_alloc() and isa_mem_free() functions, not macros, so that IOM_* constants don't have to be in scope in order to call these. Also, fix a fencepost in isa_mem_alloc().
1.7.4.2	11-Aug-1997	thorpej	Make isa_intr_alloc() return non-zero on IRQ allocation failure, rather than panicing.
1.7.4.1	30-Jul-1997	marc	added pcmcia infrastructure and a few devices
1.18	20-Dec-2023	thorpej	Remove unnecessary <sys/malloc.h>.
1.17	01-Jul-2011	dyoung	#include <sys/bus.h> instead of <machine/bus.h>.
1.16	28-Apr-2010	dyoung	On x86, change the bus_space_tag_t to a pointer to a struct bus_space_tag. For now, bus_space_tag's only member is bst_type, the type of space, which is either X86_BUS_SPACE_IO or X86_BUS_SPACE_MEM. In the future, new bus_space_tag members will refer to override-functions installed by a new function, bus_space_tag_create(9). Add pointers to constant struct bus_space_tag, x86_bus_space_io and x86_bus_space_mem. Use them to replace most uses of X86_BUS_SPACE_IO and X86_BUS_SPACE_MEM. Add an x86-specific bus_space_is_equal(9) implementation that compares the two tags' bst_type.
1.15	20-Apr-2010	dyoung	Re-uppercase x86_bus_space_io.
1.14	19-Apr-2010	dyoung	Add default implementations for bus_space_is_equal(9), bus_space_tag_create(9), and bus_space_tag_destroy(9). Use bus_space_is_equal(9) throughout the kernel to compare bus_space_tag_t's. Tested on i386 and on sparc64.

1.4	15-Aug-1997	mikel	wrap bus_space I/O tag checks with #ifdef DIAGNOSTIC. wrap actual read port map/unmap with #ifdef _KERNEL, so userland probe code will still work.
1.3	07-Aug-1997	christos	Check if we can map the read port, but don't really allocate it because it will cause a conflict with the SoundBlaster Joysticks that say that they require 200/8 and 207 is usually the read port. XXX: This is a hack.

1.11.6.2	26-Sep-2001	fvdl	* add a VCLONED vnode flag that indicates a vnode representing a cloned device. * rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass to VOP_REVOKE * the revoke system call will revoke all aliases, as before, but not the clones * vdevgone is called when detaching a device, so make it use REVOKECLONE to get rid of all clones as well * clean up all uses of VOP_OPEN wrt. locking. * add a few VOPS to spec_vnops that need to do something when it's a clone vnode (access and getattr) * add a copy of the vnode vattr structure of the original 'master' vnode to the specinfo of a cloned vnode. could possibly redirect getattr to the 'master' vnode, but this has issues with revoke * add a vdev_reassignvp function that disassociates a vnode from its original device, and reassociates it with the specified dev_t. to be used by cloning devices only, in case a new minor is allocated. * change all direct references in drivers to v_devcookie and v_rdev to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes when debugging race conditions that still exist wrt. locking and revoking vnodes. * make the locking state of a vnode consistent when passed to d_open and d_close (unlocked). locked would be better, but has some deadlock issues
1.11.6.1	07-Sep-2001	thorpej	Commit my "devvp" changes to the thorpej-devvp branch. This replaces the use of dev_t in most places with a struct vnode *. This will form the basic infrastructure for real cloning device support (besides being architecurally cleaner -- it'll be good to get away from using numbers to represent objects).

1.5	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

1.58	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.57	24-Apr-2021	thorpej	branches: 1.57.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.40	07-Jan-2002	thorpej	Overhaul of the ISA autoconfiguration code to support direct configuration of devices logically attached to the ISA bus: * Change the isa_attach_args to have arrays of io, mem, irq, drq resources. * Add a "pnpnames" and a linked list of "pnpcompatnames" to the isa_attach_args. If either of these members are non-NULL, direct configuration of the bus is being performed. Add an ISA_DIRECT_CONFIG() macro to test for this. * Drivers are not allowed to modify the isa_attach_args unless direct configuration is not being performed and the probe fucntion is returning success. * Adapt device drivers -- currently, all driver probe routines return "no match" if ISA_DIRECT_CONFIG() evaluates to true.

1.30	21-Oct-1996	thorpej	New bus.h implementation/interface: - No more distinction between i/o-mapped and memory-mapped devices. It's all "bus space" now, and space tags differentiate the space with finer grain than the bus chipset tag. - Add memory barrier methods. - Implement space alloc/free methods. - Implement region read/write methods (like memcpy to/from bus space). This interface provides a better abstraction for dealing with machine-independent chipset drivers.

1.37.8.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.38.10.3	10-Oct-2002	jdolecek	sync kqueue with -current; this includes merge of gehenna-devsw branch, merge of i386 MP branch, and part of autoconf rototil work

1.41.4.2	17-Mar-2002	atatat	Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.

1.55	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.54	24-Apr-2021	thorpej	branches: 1.54.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.40	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.39	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.38	17-Mar-2002	atatat	branches: 1.38.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.37	07-Jan-2002	thorpej	Overhaul of the ISA autoconfiguration code to support direct configuration of devices logically attached to the ISA bus: * Change the isa_attach_args to have arrays of io, mem, irq, drq resources. * Add a "pnpnames" and a linked list of "pnpcompatnames" to the isa_attach_args. If either of these members are non-NULL, direct configuration of the bus is being performed. Add an ISA_DIRECT_CONFIG() macro to test for this. * Drivers are not allowed to modify the isa_attach_args unless direct configuration is not being performed and the probe fucntion is returning success. * Adapt device drivers -- currently, all driver probe routines return "no match" if ISA_DIRECT_CONFIG() evaluates to true.

May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.20	24-Dec-1995	mycroft	The IST_* and IPL_* constants are not bus-specific; don't treat them as such. Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.
1.19	05-Oct-1995	mycroft	Use ISA_IPL_TTY, to fix race conditions.

1.38.4.2	17-Mar-2002	atatat	Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.

1.54.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.154	12-Feb-2014	dsl	Change i386 to use x86/fpu.c instead of i386/isa/npx.c This changes the trap10 and trap13 code to call directly into fpu.c, removing all the code for T_ARITHTRAP, T_XMM and T_FPUNDA from i386/trap.c Not all of the code thate appeared to handle fpu traps was ever called! Most of the changes just replace the include of machine/npx.h with x86/fpu.h (or remove it entirely).
1.153	09-Feb-2014	dsl	Tidy up and correct some comments. Replace the hand generated 28 lines that initialised fpetable[] with some pre-processor expressions. The latter was verified to give the same table entries.
1.152	04-Feb-2014	dsl	There is no need to check for recursive calls into fpudna(). Rename the associated ci_fpsaving field to 'unused'. I'm not sure they could ever happen, you could get unwanted calls into the fpu trap code while saving state when using INT13 - but these are different. The return value from the i386 fpudna() was always 1 - possibly a historic relic of the kernel fp emulation. Remove and don't check in trap.S. The amd64 and i386 fpudna() code is now almost identical.
1.151	03-Feb-2014	dsl	Since we always run with CR0.NE set (internal fpu using vector 0x10) npxintr() is only generated when a process executes an FP instruction and the TS set interrupt takes precedence - so we know the current lwp owns the fp registers. It is also then impossible to get a splurious error while saving the registers. Ths lets the npxintr() code be simplified somewhat. XXX: I'm not at all sure it really DTRT if the process actually wished to fixup anything in the signal handler (or even if the signal is masked).
1.150	02-Feb-2014	dsl	Minor fpu initialisation cleanups: Set default CR) so that the FPU is enabled (unset CR0_EM) and initialise i386_fpu_present to 1. No need to call the npx trap indirectly, rename to fpunda() to match amd64. Remove the i386_fpu_exception variable and sysctl (It used to indicate which irq was used for fpu exceptions, but we only support 'internal' now). Hopefully no one cares. fpuinit() now only needs to clear TS before the fninit(). Apart from the checks for 486SX and the 'fdiv bug' this matches the amd64 version. Exclude fpuinit() from XEN kernels, they don't call it - which rather begs the question as to whether it is needed at all!
1.149	26-Jan-2014	dsl	Remove support for 'external' floating point units and the MS-DOS compatible method of handling floating point exceptions. Make kernel support for teh fpu non-optional (486SX should still work). Only 386 cpus support external fpu, and i386 support was removed years ago. This means that the npx code no longer uses port 0xf0 or interupt 13. All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c is now mandatory for all i386 kernels. I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu() to match the very similar amd64 functions. The fpu of the boot cpu is now initialised by a direct call from cpu_configure(), this enables FP emulation for a 486SX. (for amd64 the cr0 values are set in locore.S and similar). This fixes a long-standing bug in linux_setregs() - which did not save the fpu regsiters if they were active. I've test booted a single cpu i386 kernel (using anita). amd64 builds - none of teh changes should affect it. The i386 XEN kernels build, but I'm not sure where they set cr0, and it might have got lost!
1.148	19-Jan-2014	dsl	Flatten the floating point register structures bu moving the 'environment' registers into the main strcuture. There are x87 instructions that only affect the environment, but that is no real excuse for all the sub-structures. Rename fields so that there are far fewer collisions between the two sets of field names.
1.147	08-Dec-2013	dsl	Rename the fields of 'struct envxmm' (itself badly named) so that they are different from those used for the x87 fpu. Use a union to describe the 64bit 'address' field so that it correctly spilt for 32bit binaries. The freebsd emulation defined its own 'struct freebsd_env87' that the code just assumed matched the netbsd one. Since this is a hardware structure, just use the netbsd one. This shouldn't change the binaries except that 'en_fos' used to be incorrectly a 32bit field.
1.146	01-Dec-2013	christos	revert fpu/pcu changes until we figure out what's wrong; they cause random freezes
1.145	08-Nov-2013	christos	Fix unused variable warnings
1.144	23-Oct-2013	drochner	Use the MI "pcu" framework for bookkeeping of npx/fpu states on x86. This reduces the amount of MD code enormously, and makes it easier to implement support for newer CPU features which require more fpu state, or for fpu usage by the kernel. For access to FPU state across CPUs, an xcall kthread is used now rather than a dedicated IPI. No user visible changes intended.
1.143	11-Aug-2011	cherry	branches: 1.143.2; 1.143.12; 1.143.16; unbreak the build. #include <sys/cpu.h>

1.139	20-Dec-2010	matt	branches: 1.139.6; Move counting of faults, traps, intrs, soft[intr]s, syscalls, and nswtch from uvmexp to per-cpu cpu_data and move them to 64bits. Remove unneeded includes of <uvm/uvm_extern.h> and/or <uvm/uvm.h>.

1.137	17-Jun-2010	christos	Only clear the interrupt latch if we are using interrupts!
1.136	18-Apr-2010	jym	This patch fixes the NX regression issue observed on amd64 kernels, where per-page execution right was disabled (therefore leading to the inability of the kernel to detect fraudulent use of memory mappings marked as not being executable). - replace cpu_feature and ci_feature_flags variables by cpu_feature and ci_feat_val arrays. This makes it cleaner and brings kernel code closer to the design of cpuctl(8). A warning will be raised for each CPU that does not expose the same features as the Boot Processor (BP). - the blacklist of CPU features is now a macro defined in the specialreg.h header, instead of hardcoding it inside MD initialization code; fix comments. - replace checks against CPUID_TSC with the cpu_hascounter() function. - clean up the code in init_x86_64(), as cpu_feature variables are set inside cpu_probe(). - use cpu_init_msrs() for i386. It will be eventually used later for NX feature under i386 PAE kernels. - remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already performed by cpu_hatch() through cpu_init_msrs(). - remove cpu_signature and feature_flags members from struct mpbios_proc (they were never used). This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines. XXX Should kernel rev be bumped? XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.

As this was triggered by npxsave_cpu/fpusave_cpu not working for a different CPU, remove the cpu_info argument and adjust npxsave_/fpusave_ to use bool for the save. OK ad@
1.122	11-Jan-2008	bouyer	Merge the bouyer-xeni386 branch to head, at tag bouyer-xeni386-merge1 (the branch is still active and will see i386PAE support developement). Sumary of changes: - switch xeni386 to the x86/x86/pmap.c, and the xen/x86/x86_xpmap.c pmap bootstrap. - merge back most of xen/i386/ to i386/i386 - change the build to reduce diffs between i386 and amd64 in file locations - remove include files that were identical to the i386/amd64 counterparts, the build will find them via the xen-ma/machine link.
1.121	26-Dec-2007	yamt	- share idt entry allocation code among x86. - introduce a function to reserve an idt entry and use it instead of manipulating idt_allocmap directly. - rename idt to xen_idt for amd64 xen. add missing #ifdef XEN.

1.118	17-Oct-2007	garbled	branches: 1.118.2; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.
1.117	26-Sep-2007	ad	branches: 1.117.2; x86 changes for pcc and LKMs. - Replace most inline assembly with proper functions. As a side effect this reduces the size of amd64 GENERIC by about 120kB, and i386 by a smaller amount. Nearly all of the inlines did something slow, or something that does not need to be fast. - Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL. In that case make them inlines. Makes curlwp LKM and preemption safe. - Make bus_space and bus_dma more LKM friendly. - Share a few more files between the ports. - Other minor changes.

1.88	22-Nov-2002	fvdl	New interrupt code. The basic idea behind it is to hide the differences in interrupt controllers in struct pic, and try to keep as much common code as possible. At the lowest (asm) level, this is done with CPP macros. The main structure is now struct intrsource, describing an established interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic). For quick masking, there may be a maximum of 32 sources per CPU. Sources can be assigned to any CPU in the MP case, though currently they all go to the boot CPU.
1.87	05-Oct-2002	fvdl	Adjust callers to setgate() to match new extra parameter.
1.86	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.85	01-Apr-2002	jdolecek	Make work on FPU-less computers again - if FPU is not detected in npxprobe1(), set npxdna_func to new npxdna_empty(). This function just returns 0 and thus fallbacks to a T_DNA trap (and math emulate, if present). This fixes kern/15828 by Masaru Oki, tested on 386DX machine. Reviewed by Jason Thorpe. make npxdna_s87() and npxdna_xmm() static g/c (npx_type == NPX_NONE) test from npxdna_s87(), it's no longer needed
1.84	10-Jan-2002	enami	Cope with rev. 1.16 of frame.h; trapframe now starts at if_gs in intrframe. This fixes PR#14040.
1.83	08-Jan-2002	toshii	Remove fwait after fxsave. Raising math exception from fpu_save causes machine reboots. Also, this fwait would cause incorrect results, as pending exceptions are to be handled later after fxrstor.
1.82	15-Nov-2001	lukem	add RCSID
1.81	03-Sep-2001	thorpej	Eliminate a needless test, pointed out by Bill Sommerfeld.
1.80	03-Aug-2001	thorpej	Upon further reading of the manual, don't save the MXCSR-at-last-exception. Its status bits are sticky, and unaffacted by FNINIT.
1.79	03-Aug-2001	thorpej	Remember the MXCSR at last-exception the way we do the FPU SW/TW.
1.78	02-Aug-2001	thorpej	- Rename cpu_use_fxsave to i386_use_fxsave. - If we detect SSE/SSE2 support in the CPU, enable SSE exceptions and set i386_has_{sse,sse2} as appropriate. - Expose i386_use_fxsave and i386_has_{sse,sse2} through sysctl as machdep.{osfsxr,sse,sse2}.
1.77	02-Aug-2001	thorpej	Add support for saving/restoring SSE/SSE2 state using FXSAVE/FXRSTOR. Reviewed by Frank.
1.76	17-May-2001	lukem	branches: 1.76.2; don't bother providing duplicate code for {read,write}_eflags() since it's in cpufuncs.h anyway
1.75	26-Apr-2001	thorpej	Explicitly include <machine/pio.h>.
1.74	17-Jan-2001	fvdl	branches: 1.74.2; Export some variables.

1.70	06-Oct-1999	fvdl	branches: 1.70.2; 1.70.8; Set variable i386_fpu_present to 1 if a functional FPU was detected. For later retrieval by sysctl.
1.69	24-Mar-1999	mrg	branches: 1.69.8; completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.68	26-Jan-1999	christos	move the assembly functions to locore.s and make the variables used by them non-static
1.67	22-Mar-1998	drochner	switch to non-BROKEN_INDIRECT_CONFIG
1.66	20-Mar-1998	mycroft	In npxdna(), if there was an exception state in the FPU but npxproc was null, the frstor would fault on a PPro. I'm pretty sure this is not how the chip is supposed to behave, but it's easy enough to do a fninit to throw away the exception state. Also, some other minor changes to the documentation.
1.65	10-Feb-1998	mrg	- add defopt's for UVM, UVMHIST and PMAP_NEW. - remove unnecessary UVMHIST_DECL's.
1.64	06-Feb-1998	mrg	add the i386 MD portions for UVM.
1.63	24-Jan-1998	mycroft	Store the initial NPX control word appropriate for the emulation in the saved FPU state, and use it when initializing the FPU on demand.
1.62	23-Jan-1998	mycroft	Some rearrangement of the startup code: * Move some of the memory bootstrapping and the DDB startup earlier. * Always put the IDT and the initial GDT and LDT in a separate page. * Various minor changes.
1.61	12-Jan-1998	thorpej	Update for changes to config.
1.60	16-Oct-1997	mycroft	branches: 1.60.2; Need vmmeter.h here now.

1.55	11-Apr-1996	cgd	update for addition of a machine-dependent cookie as the first argument to isa_intr_{,dis}establish().
1.54	17-Mar-1996	thorpej	New device attachment scheme: - split softc size and match/attach out from cfdriver into a new struct cfattach. - new "attach" directive for files.*. May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.53	07-Jan-1996	mycroft	Put #includes in the right order.
1.52	24-Dec-1995	mycroft	The IST_* and IPL_* constants are not bus-specific; don't treat them as such. Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.
1.51	10-Oct-1995	mycroft	Add USERMODE() and KERNELMODE() macros, and use them.
1.50	05-Oct-1995	mycroft	Remove unneeded input operands to fnsave(), fnstcw(), and fnstsw().

1.46	06-Aug-1995	mycroft	Eliminate direct uses of curproc in npxdna() and npxinit().
1.45	06-Aug-1995	mycroft	Stop using cr0 to flag that the FPU has not been used.
1.44	06-Aug-1995	mycroft	Move the `used fpu' flag into mdproc, so it can be referenced when a process is swapped out. Implement process_{read,write}_fpregs.
1.43	04-May-1995	mycroft	If we decide to use IRQ 13, explicitly turn off CR0_NE to be sure.
1.42	04-May-1995	mycroft	Update a comment to match that last change.
1.41	04-May-1995	mycroft	npxinit() should not be called during autoconfig now. Watch for this condition.
1.40	04-May-1995	mycroft	Move some comments from before npxsave1() to before npxsave().

1.30	18-Nov-1994	mycroft	Convert port, IRQ, and DRQ numbers to ints.
1.29	07-Nov-1994	mycroft	Garbage collect some variables which are no longer used.
1.28	07-Nov-1994	mycroft	Since npxdna() and npxsave() are only ever called at spl0 now, we can get rid of all the overhead of frobbing the IDT, and just use a simple flag to tell npxintr() to ignore interrupts. This allows lots of code reduction. Also, update some comments and add some DIAGNOSTIC code to detect is these assumptions ever become wrong.
1.27	06-Nov-1994	mycroft	Only save the FPU state if somebody else needs the FPU, or when forking.
1.26	04-Nov-1994	mycroft	Make IRQ_SLAVE a plain number, too, and remove IRQ{0-15}.
1.25	04-Nov-1994	mycroft	Change all of the uses of IRQ{0-15} and bit masks to use plain numbers rather than bit shifting.

1.20	05-May-1994	cgd	lots of changes: prototype migration, move lots of variables, definitions, and structure elements around. kill some unnecessary type and macro definitions. standardize clock handling. More changes than you'd want.
1.19	24-Apr-1994	mycroft	Rename two files.
1.18	07-Apr-1994	mycroft	Implement dynamic IRQ configuration and IRQ sharing. Inline spl*() calls. Reorganize and clean up the relevant code.

1.12	03-Jan-1994	mycroft	Inline all the [lr]cr[023]() `functions' in cpufunc.h.
1.11	20-Dec-1993	mycroft	Use cpufunc.h only where (currently) needed.
1.10	20-Dec-1993	mycroft	Canonicalize all #includes, and add pio.h where appropriate.

1.8	16-Sep-1993	brezak	Changes to use a trap frame for syscalls.
1.7	14-Jun-1993	cgd	branches: 1.7.4; say "using exception 16" rather than "exception 16"; the latter lookes like it could be an error message...
1.6	27-May-1993	proven	Cleaned up a little.
1.5	26-May-1993	proven	Compiles with gcc-2.3.3 now.

1.3	09-May-1993	deraadt	npx patches from Bruce Evans. patchkit 10002
1.2	03-Apr-1993	cgd	added changes from Steven Reiz <sreiz@aie.nl> (based on those by Poul-Henning Kamp <phk@data.fls.dk>) to get the kernel to compile properly when gcc2.* is cc. (should still work when gcc1.39 is in use.)
1.1	21-Mar-1993	cgd	branches: 1.1.1; Initial revision
1.1.1.1	21-Mar-1993	cgd	initial import of 386bsd-0.1 sources

1.7.4.12	14-Nov-1993	mycroft	Remove some more gratuitous casting.
1.7.4.11	08-Nov-1993	mycroft	If we get an unexpected DNA, try to clean up and keep running anyway.
1.7.4.10	26-Oct-1993	mycroft	Set to I/O area size. Don't bother to do the fwait while probing.
1.7.4.9	17-Oct-1993	mycroft	Minor cleanup.
1.7.4.8	16-Oct-1993	mycroft	Add missing dv_class entry to cfdrivers, and use dv_xname where appropriate.
1.7.4.7	13-Oct-1993	mycroft	Remove unused intrframe.
1.7.4.6	12-Oct-1993	mycroft	Remove stupid special case for immediate signal processing. This doesn't save more than a few cycles, and causes interrupt frames to be bogusly large.
1.7.4.5	11-Oct-1993	mycroft	#include pio.h where needed, and remove cpufunc.h.
1.7.4.4	10-Oct-1993	mycroft	load_cr0 --> lcr0
1.7.4.3	09-Oct-1993	mycroft	Make npxintr() non-static so locore can get to it.
1.7.4.2	07-Oct-1993	mycroft	Convert to new config, with some general cleanup.
1.7.4.1	24-Sep-1993	mycroft	clock.c: Finish conversion. Make rtcput() work if VRT bit not set. Speed up time conversion in delay(). fd.c: Minor changes to autoconfig. Use dv_parent rather than storing another pointer to the fdc_softc in each fd_softc. Change disk label stuff for our kernel. icu.s: Make splx() and splnone() return previous cpl for now. isa.c: Minor autoconfig changes. isa.h: rtcin() is now nvram() and is declare in nvram.h. Make isaphysmem a caddr_t. pccons.c: XXXX: Maybe we should insist they open /dev/io now. timerreg.h: #define TIMER_NPORTS. wd.c: Delete unused wdnoreloc() and wddospart(), and use remaining two bits in unit number. struct disk --> struct wd_softc. struct board --> struct wdc_softc. Still needs much work.
1.60.2.2	05-May-1998	mycroft	Pull up 1.66, per request of mycroft.
1.60.2.1	29-Jan-1998	mellon	Pull up 1.63 (mycroft)
1.69.8.1	27-Dec-1999	wrstuden	Pull up to last week's -current.

1.70.8.11	23-Jan-2001	thorpej	Sync with the trunk.
1.70.8.10	10-Jan-2001	sommerfeld	Significant rewrite of slave CPU attach and initialization, centering on identifycpu() and spreading outward. Separate feature probes (cpuid invocation), which runs on the cpu being attached, from the display of this information, which runs on the boot cpu; remove some of the probe code from locore as it doesn't need to run that early. We now spin up secondary cpu's during cpu_attach, have them do a cpu feature probe, and then have them spin waiting for a "go" signal. We no longer pay attention to the cpu signature and cpuid features reported by the MP BIOS since those are known to be truncated for at least some bioses. We now do npx initialization (including FDIV bug detection) on all cpus. XXX Change some of the cyrix bug workarounds to fit the new identifycpu() system; this is untested.
1.70.8.9	09-Jan-2001	sommerfeld	Fix two bugs preventing this from working if !MULTIPROCESSOR 1) ci->ci_curproc is not (yet) used in uniprocessor mode. 2) change a "pushl cpu_info_primary" to the intended "pushl $cpu_info_primary" (oops)
1.70.8.8	25-Aug-2000	sommerfeld	Get this to at least build again in the !MULTIPROCESSOR case..
1.70.8.7	18-Aug-2000	sommerfeld	GC dead code.
1.70.8.6	18-Aug-2000	sommerfeld	Restructure (based somewhat on how Jason adapted this for the alpha). Now works in the multiprocessor case.
1.70.8.5	07-Aug-2000	sommerfeld	Merge sommerfeld_i386mp_1 branch forward to 20000806 sources
1.70.8.4	26-Jun-2000	sommerfeld	Start making npx.c MP-safe; Interface to npx now specifies the process and/or cpu to act on. Implement an IPI for MP lazy FP save. Tested and working when only one CPU is running; untested in the MP case since we can't run user processes on multiple CPU's yet. Along for the ride: - Change i386_send_ipi to take a "struct cpu_info *" rather than a cpu number. - Turn off the "give me the brain" test IPI's.
1.70.8.3	25-Jun-2000	sommerfeld	Merge up to just-post-1.5 -current

1.70.2.2	18-Jan-2001	bouyer	Sync with head (for UBC+NFS fixes, mostly).
1.70.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.74.2.12	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.103.2.2	07-Jul-2004	tron	branches: 1.103.2.2.2; 1.103.2.2.4; Pull up revision 1.106 (requested by mycroft in ticket #611): Back out part of the changes in rev 1.86. Remove npxdna_notset(), and instead have the DNA trap handler point to npxdna_empty() by default. This way, if there are no npx devices found and MATH_EMULATE is not configured, we go back to the old behavior of issuing a SIGKILL and printing: pid XXX killed due to lack of floating point rather than panicking.

1.116.22.3	06-Nov-2007	joerg	Refactor PNP API: - Make suspend/resume directly a device functionality. It consists of three layers (class logic, device logic, bus logic), all of them being optional. This replaces D0/D3 transitions. - device_is_active returns true if the device was not disabled and was not suspended (even partially), device_is_enabled returns true if the device was enabled. - Change pnp_global_transition into pnp_system_suspend and pnp_system_resume. Before running any suspend/resume handlers, check that all currently attached devices support power management and bail out otherwise. The latter is not done for the shutdown/panic case. - Make the former bus-specific generic network handlers a class handler. - Make PNP message like volume up/down/toogle PNP events. Each device can register what events they are interested in and whether the handler should be global or not. - Introduce device_active API for devices to mark themselve in use from either the system or the device. Use this to implement the idle handling for audio and input devices. This is intended to replace most ad-hoc watchdogs as well. - Fix somes situations in which audio resume would lose mixer settings. - Make USB host controllers better deal with suspend in the light of shared interrupts. - Flush filesystem cache on suspend. - Flush disk caches on suspend. Put ATA disks into standby on suspend as well. - Adopt drivers to use the new PNP API. - Fix a critical bug in the generic cardbus layer that made D0->D3 break. - Fix ral(4) to set if_stop. - Convert cbb(4) to the new PNP API. - Apply the PCI Express SCI fix on resume again.

1.23	26-Jan-2014	dsl	Remove support for 'external' floating point units and the MS-DOS compatible method of handling floating point exceptions. Make kernel support for teh fpu non-optional (486SX should still work). Only 386 cpus support external fpu, and i386 support was removed years ago. This means that the npx code no longer uses port 0xf0 or interupt 13. All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c is now mandatory for all i386 kernels. I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu() to match the very similar amd64 functions. The fpu of the boot cpu is now initialised by a direct call from cpu_configure(), this enables FP emulation for a 486SX. (for amd64 the cr0 values are set in locore.S and similar). This fixes a long-standing bug in linux_setregs() - which did not save the fpu regsiters if they were active. I've test booted a single cpu i386 kernel (using anita). amd64 builds - none of teh changes should affect it. The i386 XEN kernels build, but I'm not sure where they set cr0, and it might have got lost!

1.20	02-Apr-2009	dyoung	During shutdown, detach devices in an orderly fashion. Call the detach routine for every device in the device tree, starting with the leaves and moving toward the root, expecting that each (pseudo-)device driver will use the opportunity to gracefully commit outstandings transactions to the underlying (pseudo-)device and to relinquish control of the hardware to the system BIOS. Detaching devices is not suitable for every shutdown: in an emergency, or if the system state is inconsistent, we should resort to a fast, simple shutdown that uses only the pmf(9) shutdown hooks and the (deprecated) shutdownhooks. For now, if the flag RB_NOSYNC is set in boothowto, opt for the fast, simple shutdown. Add a device flag, DVF_DETACH_SHUTDOWN, that indicates by its presence that it is safe to detach a device during shutdown. Introduce macros CFATTACH_DECL3() and CFATTACH_DECL3_NEW() for creating autoconf attachments with default device flags. Add DVF_DETACH_SHUTDOWN to configuration attachments for atabus(4), atw(4) at cardbus(4), cardbus(4), cardslot(4), com(4) at isa(4), elanpar(4), elanpex(4), elansc(4), gpio(4), npx(4) at isa(4), nsphyter(4), pci(4), pcib(4), pcmcia(4), ppb(4), sip(4), wd(4), and wdc(4) at isa(4). Add a device-detachment "reason" flag, DETACH_SHUTDOWN, that tells the autoconf code and a device driver that the reason for detachment is system shutdown. Add a sysctl, kern.detachall, that tells the system to try to detach every device at shutdown, regardless of any device's DVF_DETACH_SHUTDOWN flag. The default for kern.detachall is 0. SET IT TO 1, PLEASE, TO HELP TEST AND DEBUG DEVICE DETACHMENT AT SHUTDOWN. This is a work in progress. In future work, I aim to treat pseudo-devices more thoroughly, and to gracefully tear down a stack of (pseudo-)disk drivers and filesystems, including cgd(4), vnd(4), and raid(4) instances at shutdown. Also commit some changes that are not easily untangled from the rest: (1) begin to simplify device_t locking: rename struct pmf_private to device_lock, and incorporate device_lock into struct device. (2) #include <sys/device.h> in sys/pmf.h in order to get some definitions that it needs. Stop unnecessarily #including <sys/device.h> in sys/arch/x86/include/pic.h to keep the amd64, xen, and i386 releases building.

If either of these members are non-NULL, direct configuration of the bus is being performed. Add an ISA_DIRECT_CONFIG() macro to test for this. * Drivers are not allowed to modify the isa_attach_args unless direct configuration is not being performed and the probe fucntion is returning success. * Adapt device drivers -- currently, all driver probe routines return "no match" if ISA_DIRECT_CONFIG() evaluates to true.

1.9	26-Jan-2014	dsl	Remove support for 'external' floating point units and the MS-DOS compatible method of handling floating point exceptions. Make kernel support for teh fpu non-optional (486SX should still work). Only 386 cpus support external fpu, and i386 support was removed years ago. This means that the npx code no longer uses port 0xf0 or interupt 13. All the "npx at isa" lines go from the configs, arch/i386/isa/npx.c is now mandatory for all i386 kernels. I've renamed npxinit() to fpuinit() and npxinit_cpu() to fpuinit_cpu() to match the very similar amd64 functions. The fpu of the boot cpu is now initialised by a direct call from cpu_configure(), this enables FP emulation for a 486SX. (for amd64 the cr0 values are set in locore.S and similar). This fixes a long-standing bug in linux_setregs() - which did not save the fpu regsiters if they were active. I've test booted a single cpu i386 kernel (using anita). amd64 builds - none of teh changes should affect it. The i386 XEN kernels build, but I'm not sure where they set cr0, and it might have got lost!

1.2	22-Nov-2002	fvdl	branches: 1.2.6; New interrupt code. The basic idea behind it is to hide the differences in interrupt controllers in struct pic, and try to keep as much common code as possible. At the lowest (asm) level, this is done with CPP macros. The main structure is now struct intrsource, describing an established interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic). For quick masking, there may be a maximum of 32 sources per CPU. Sources can be assigned to any CPU in the MP case, though currently they all go to the boot CPU.

Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted.

1.179	30-Sep-2006	elad	Implement the "device" scope. It uses an authorization wrapper per device class on the system to ensure type-safety. For now, it supports only terminal (TTY) devices, and has two actions for them: "open terminal" and "privileged set". Sample usage has been added to i386 and hp300 code for reference. Update documentation.

1.169	13-Mar-2004	bjh21	branches: 1.169.8; 1.169.10; Abstract the interface between pckbc(4), and the pckbd(4) and pms(4) drivers that attach to it. This allows for other host interface chips that use the same keyboards and mice, such as the ones in the ARM IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still called pckbc(4), and the new abstraction layer is "pckbport", so the child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which also contains some code shared between all host controllers. To avoid incompatibility, pckbdreg.h is still installed in /usr/include/dev/pckbc. In theory, this shouldn't cause any behavioural changes in the drivers concerned. Thy just use rather more function pointers than before. Tested on i386 and (with a new host driver) acorn32. Compiled on several other affected architectures.

1.154	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

1.152	17-Mar-2002	atatat	Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.151	07-Jan-2002	thorpej	Overhaul of the ISA autoconfiguration code to support direct configuration of devices logically attached to the ISA bus: * Change the isa_attach_args to have arrays of io, mem, irq, drq resources. * Add a "pnpnames" and a linked list of "pnpcompatnames" to the isa_attach_args. If either of these members are non-NULL, direct configuration of the bus is being performed. Add an ISA_DIRECT_CONFIG() macro to test for this. * Drivers are not allowed to modify the isa_attach_args unless direct configuration is not being performed and the probe fucntion is returning success. * Adapt device drivers -- currently, all driver probe routines return "no match" if ISA_DIRECT_CONFIG() evaluates to true.

1.149	31-Jul-2001	jdolecek	branches: 1.149.4; Make console polling (cnpollc/cngetc) work on IBM PS/2 keyboard controller using level triggered interrupts, which livelocks calling intr routine if the data register is not read in the interrupt routine, as it's case when polling after interrupts are enabled during boot. Block all interrupts when polling for keypress, and modify intr routine to read and store value from data register. The latter one is to avoid losing a keypress when one would manage to press a key when kernel is not in spl-guarded code section. Tested with classic pccons, 'pcconskbd at pckbc' and 'pckbd at pckbc' configurations, on i386.

1.146	02-Jun-2001	jdolecek	When polling, raise priority level to tty, to block keyboard interrupts when the system is "warm", i.e. interrupts are not blocked anymore. This seems to be necessary on my PS/2 Model 70 keyboard - without this, system ends up in endless loop calling the keyboard intr routine if a key is pressed when polling. This _may_ be just specific to level-triggered interrupts PS/2 MCA uses, though it's more likely it's just the way the particular keyboard controller works. Discussed on tech-kern@.
1.145	02-May-2001	scw	Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point in each tty driver to indirect through it. This allows tty line-disciplines to handle poll(2) system calls.

Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

1.139	23-Mar-2000	thorpej	branches: 1.139.4; New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.

1.112	01-Oct-1997	drochner	Fix the problem described in PR port-i386/4177: scroll lock could cause tsleep() to be called from an interrupt handler. The semantics of the scroll-lock key is changed now: it issues a ^S or ^Q, depending on the current state. (It should probably issue tp->t_cc[VSTOP] or tp->t_cc[VSTART] instead, but this would require more serious structural changes because there is not always a tty context present.) The "scroll lock" LED is now controlled by pcstart()/pcstop(), so it will show the real state even if the start/stop characters are remapped or the normal ^S/^Q are used.

Originally supplied in PR #1529 2) Add option PCCONS_REAL_BS which (for US keyboards only) forces backspace to really be backspace and not delete. Intended to close PR #2264 submitted by Greg Woods. He wanted it changed for everyone -- I thought adding a kernel compile option was friendlier.

1.21	16-Jun-1993	mycroft	Make sysbeep() take a frequency, not a timer count, and add constants BEEP_FREQ and BEEP_TIME which can be overridden in the config file.
1.20	31-May-1993	cgd	fix bogus initializer
1.19	28-May-1993	deraadt	1. It is now possible to build a kernel that does not have a pc0 device driver. 2. "press any key to reboot" reads the key from the console. 3. wddump() still needs a non-blocking getc() routine (or flush)
1.18	26-May-1993	deraadt	tty dynamic allocation
1.17	22-May-1993	cgd	add rcsids to everything and clean up headers
1.16	18-May-1993	cgd	make kernel select interface be one-stop shopping & clean it all up.
1.15	10-May-1993	deraadt	ring buffer code now uses rbchar's (shorts) instead of chars.
1.14	04-May-1993	mycroft	Don't autorepeat locking keys. (Can someone test this with X?)
1.13	26-Apr-1993	mycroft	Oops. sgetc() is used elsewhere, so should not be static.
1.12	22-Apr-1993	mycroft	Rename sput to sputc and make it and sgetc static.
1.11	22-Apr-1993	mycroft	Use rb_read to gather output; do exactly 4 spl calls, and don't hold the interrupts locked very long, lest we overrun our serial port FIFOs.
1.10	21-Apr-1993	mycroft	Huge performance improvement (not so bloody many spl calls)!
1.9	20-Apr-1993	mycroft	Slight performance improvement.
1.8	20-Apr-1993	mycroft	Fix typo in last change.
1.7	20-Apr-1993	mycroft	Don't output NULs.
1.6	11-Apr-1993	deraadt	Whoops. vidio card io space is 16 bytes large, not 8 bytes large. probe now returns the right thing
1.5	11-Apr-1993	deraadt	nay, pccons.c still did not return the right thing from probe.. --> 8
1.4	10-Apr-1993	glass	fixed to be compliant, subservient, and to take advantage of the newly hacked config(8)
1.3	08-Apr-1993	deraadt	dmesg output at boottime now tries to print out information as soon as it is available. The output looks much more like Sunos.

1.31.2.23	03-Nov-1993	mycroft	Read exactly one character per interrupt, and just assume it's there. (This is important for pms.)
1.31.2.22	31-Oct-1993	mycroft	Nuke some unused externs.
1.31.2.21	29-Oct-1993	mycroft	Don't output NULs.
1.31.2.20	28-Oct-1993	mycroft	Make ps_state a plain integer rather than a bitmap.
1.31.2.19	28-Oct-1993	mycroft	After a successful probe, patch the video memory back so we don't leave a blinking `Z' in the corner of the screen.
1.31.2.18	27-Oct-1993	mycroft	Don't panic! If the user presses a lock key during pccngetc(), that is.
1.31.2.17	27-Oct-1993	mycroft	Make pcforceintr() actually work.
1.31.2.16	27-Oct-1993	mycroft	Ignore receiver interrupts if we are in pccngetc().
1.31.2.15	26-Oct-1993	mycroft	Put arguments to pcattach() is correct order.
1.31.2.14	26-Oct-1993	mycroft	Rearrange do_async_update() to allow printf()s in kbd_cmd() without looping. Allow hard-wired configurations. Round shared memory size up to 1k. Add some debugging code. Set a default attribute in pccninit(). Stack `kernel' variable to avoid resetting it inside DDB.
1.31.2.13	18-Oct-1993	mycroft	More reorg. Should be `finished' now.
1.31.2.12	17-Oct-1993	mycroft	Way hacked. Don't ask.
1.31.2.11	17-Oct-1993	mycroft	Minor cleanup.
1.31.2.10	16-Oct-1993	mycroft	Add missing dv_class entry to cfdrivers, and use dv_xname where appropriate.
1.31.2.9	16-Oct-1993	mycroft	Don't forget to enable the interrupt line when registering a handler. Change the first argument to isa_mem{check,alloc}() to a caddr_t.

1.31.2.5	09-Oct-1993	mycroft	Use ISA_HOLE_VADDR() to calculate Crtat, and make it static.
1.31.2.4	07-Oct-1993	mycroft	Merge changes from trunk. Allow some string contants to be compacted.
1.31.2.3	29-Sep-1993	mycroft	lms.c: Update for new config. lpa.c: Defunct. lpt.c: Update for new config. Fix handling of interrupted writes. Merge code from lpa driver. Make all operations interruptible. Remove a few other bogons. lptreg.h: Add LPT_NPORTS. pccons.c: Merge changes from trunk.
1.31.2.2	24-Sep-1993	mycroft	clock.c: Finish conversion. Make rtcput() work if VRT bit not set. Speed up time conversion in delay(). fd.c: Minor changes to autoconfig. Use dv_parent rather than storing another pointer to the fdc_softc in each fd_softc. Change disk label stuff for our kernel. icu.s: Make splx() and splnone() return previous cpl for now. isa.c: Minor autoconfig changes. isa.h: rtcin() is now nvram() and is declare in nvram.h. Make isaphysmem a caddr_t. pccons.c: XXXX: Maybe we should insist they open /dev/io now. timerreg.h: #define TIMER_NPORTS. wd.c: Delete unused wdnoreloc() and wddospart(), and use remaining two bits in unit number. struct disk --> struct wd_softc. struct board --> struct wdc_softc. Still needs much work.

1.136.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.144.4.8	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).

1.149.4.2	13-Oct-2001	fvdl	Revert the t_dev -> t_devvp change in struct tty. The way that tty structs are currently used (especially by console ttys) aren't ready for it, and this will require quite a few changes.
1.149.4.1	10-Oct-2001	fvdl	Convert all remaining devices.
1.153.4.1	19-May-2002	gehenna	Add device switch. Replace the access to devsw table and the hard-coded majors with devsw API.

1.47	05-Jun-2000	sommerfeld	branches: 1.47.6; 1.47.8; 1.47.10; If rnd is configured into the kernel, do rnd(4) entropy collection from devices connected to pckbc: - Do actual sample collection in pckbc. - Add rndsource_element_t to the slot data. - Change pckbc_set_inputhandler() to take an additional argument, the name of the device, which is (eventually) passed into rnd_attach_source() to identify the source. - Change callers of pckbc_set_inputhander() appropriately.
1.46	03-Dec-1999	thorpej	branches: 1.46.4; Split the PC-like keyboard controller driver into chip back-end and bus front-end.
1.45	19-Aug-1999	drochner	branches: 1.45.2; 1.45.8; back out last rev - it looks like a local hack which shouldn't go here, and it breaks the "opms at pckbc" case
1.44	16-Aug-1999	augustss	Add umodem device.
1.43	06-May-1999	drochner	sync diagnostic printouts in opms_pckbc_probe() with dev/pckbc/psm.c: pmsprobe() -- most notably: put a part inside #ifdef DEBUG

1.40	15-Aug-1998	mycroft	Make copyright notices with my name consistent.
1.39	22-Mar-1998	drochner	Allow to attach the mouse driver to the new MI keyboard controller driver. This should allow to use old X servers which depend on the old mouse interface to work in the future. XXX There can be only one attachment - either to an old console driver or to the new pckbc driver - be configured.
1.38	22-Mar-1998	drochner	switch to non-BROKEN_INDIRECT_CONFIG
1.37	12-Jan-1998	thorpej	Update for changes to config.

May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.25	16-Mar-1996	thorpej	Change the PS/2 mouse driver to be a child of the "pckbd" attribute, which represents the "keyboard controller". Give "pc" and "vt" drivers the "pckbd" attribute. In pcattach() (pccons and pcvt), attach children of the keyboard controller.
1.24	24-Dec-1995	mycroft	The IST_* and IPL_* constants are not bus-specific; don't treat them as such. Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

1.5	23-Jun-1993	mycroft	Oops. Reversed order of args to outb(). Still haven't gotten my 486 booted with a new kernel to actually test this, though.
1.4	14-Jun-1993	mycroft	Explicitly disable mouse during attach.
1.3	14-Jun-1993	mycroft	Fix egregious stupidity.
1.2	14-Jun-1993	mycroft	Yeah, I'm awake.
1.1	14-Jun-1993	mycroft	Add preliminary (read: untested) PS/2 mouse driver.
1.7.2.2	03-Nov-1993	mycroft	Actually compiles now...
1.7.2.1	03-Nov-1993	mycroft	Recloned from other mouse drivers. Should work, but the probe routine may cause the keyboard to lock up on machines with no auxiliary port.
1.9.2.2	19-Jul-1994	cgd	from trunk, per mycroft.

1.1	21-Mar-1993	cgd	after 0.2.2 "stable" patches applied
1.12.2.1	22-Jul-1993	cgd	slight (strange!) mod from julian to make it work with ultra34f, as well.
1.13.2.11	25-Mar-1994	mycroft	Stylistic changes.
1.13.2.10	02-Feb-1994	mycroft	Change some structure names.

1.30.2.1	27-Jul-1994	cgd	from trunk, per mycroft
1.55	22-Nov-2002	fvdl	Removed in the new intr world.
1.54	11-Nov-2002	itohy	XINTR_TSS() macro for non-ELF case whitespace nit
1.53	05-Oct-2002	fvdl	Define XINTR_TSS
1.52	03-Oct-2002	fvdl	Make shared IRQs for the normal PIC case work again as they did before the MP merge (i.e. treat them as having the lowest level of all registered handlers in the chain for the IRQ).
1.51	01-Oct-2002	fvdl	Merge Bill Sommerfeld's i386 MP branch. This code has some known caveats, but works quite well in a lot of MP cases, and all UP cases that I have tested. Parts of this will hopefully be reworked in the not-too-distant future.
1.50	10-Jun-2002	itohy	s/XHOLE_VEC/XHOLD_VEC/
1.49	31-May-2002	thorpej	Make this work with an ISO C preprocessor.
1.48	21-Sep-2001	fvdl	branches: 1.48.10; 1.48.12; Make the newer gas happy by explicitly adding '*' to indirect calls, and matching mov extensions with register names.
1.47	17-Jul-2001	mrg	branches: 1.47.2; use a shift instead of a divide.
1.46	20-Jan-2000	enami	branches: 1.46.2; 1.46.8; 1.46.10; fix typo in comment.
1.45	23-Aug-1999	kleink	branches: 1.45.2; Unlike in an i386 a.out assembler, where in an .align n directive n is meant to be the logarithm to base 2 of the alignment, in an ELF environment n is the actual alignment boundary; thus, adjust the directives accordingly. Albeit the wonderful i386 architecture doesn't mind the smaller alignment in an obvious way, it is likely to have resulted in some performance penalty during the a.out->ELF transition.
1.44	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.43	01-Dec-1998	thorpej	Use _C_LABEL() to generate C labels in assembly code, don't prepend an underscore (_) directly. (XXX Except in a few places, where traditional CPP's macro evaluation semantics break things, so we test for __ELF__ directly in those places).
1.42	15-Aug-1998	mycroft	Assign my copyrights to TNF.
1.41	04-Jul-1998	jonathan	defopt DDB.
1.40	10-Feb-1998	mrg	- add defopt's for UVM, UVMHIST and PMAP_NEW. - remove unnecessary UVMHIST_DECL's.

1.38	16-Nov-1997	mycroft	Minor change.
1.37	16-Nov-1997	mycroft	Fix a condition where we might keep interrupts blocked while servicing a soft interrupt. Fixes serial port silo overflow problems.
1.36	28-Feb-1997	mycroft	branches: 1.36.8; Import interrupt priority changes from com patches: * Make it a strict hierarchy. (It was close anyway). * Add `serial' and rename `softtty' to `softserial'. * Make soft interrupts a bit less special-case.
1.35	20-Nov-1996	mycroft	branches: 1.35.6; Remove incomplete and unused `fast' vector code.
1.34	20-Nov-1996	jonathan	Fix cut-and-paste errors.
1.33	20-Nov-1996	jonathan	* Add old-style vmstat -i interrupt counters for normal and stray interrupts. Interrupts for irqs with handlers are counted as normal, even if none of the handlers claim the interrupt. Should all be redone with hierarchical event counters. that count hardware events and invocations of each handler separately. * Increment cnt.v_intr for normal interrupts (bugfix).
1.32	07-Jan-1996	mycroft	branches: 1.32.4; Stylistic changes.
1.31	07-Jan-1996	mycroft	Deal with GCC's dead code elimination being suboptimal.
1.30	07-Jan-1996	mycroft	Build the frame for recursive interrupts manually, and make sure to disable interrupts to avoid races.
1.29	08-May-1995	mycroft	The previous optimization only works for edge-triggered interrupts...
1.28	03-May-1995	mycroft	By default, don't frob the ICU masks here. The software masking should be sufficient.
1.27	01-May-1995	mycroft	Update to match include files. Eliminate _ucodesel, _udatasel, and IdlePTD.
1.26	22-Apr-1995	mycroft	Move some comments to more appropriate places.
1.25	17-Apr-1995	cgd	clean up several ISA device interfaces: autoconfiguration, header inclusion, and interrupt configuration. more work still needs to be done, but it's getting better...
1.24	18-Nov-1994	mycroft	Remove Xwild; it's no longer used.
1.23	04-Nov-1994	mycroft	isa.h -> isareg.h
1.22	27-Oct-1994	cgd	new RCS ID format.
1.21	09-Oct-1994	mycroft	Oops; slight optimization to the previous.
1.20	09-Oct-1994	mycroft	Oops. Just fake %ebp; nothing else.
1.19	09-Oct-1994	mycroft	If DDB is configured, make a fake stack frame.
1.18	23-May-1994	cgd	branches: 1.18.2; notdef out some debug code that no longer works
1.17	18-Apr-1994	mycroft	Only report `stray' interrupts if DEBUG, since they occur normally.
1.16	15-Apr-1994	cgd	keep vmstat happy.
1.15	07-Apr-1994	mycroft	Macroize some more constants.

1.13	02-Apr-1994	mycroft	Minor code cleanup.
1.12	19-Dec-1993	mycroft	Clean up trap handling and macroize interrupt entry and exit code. From magnum branch.
1.11	17-Dec-1993	mycroft	From magnum branch: Remove Jolitz's netisr kluge. Make sure cpl == 0 really means base priority. Other minor cleanup.
1.10	02-Aug-1993	mycroft	branches: 1.10.2; Add RCS identifiers, remove some completely useless RCS logs and patchkit headers, and a few other insignificant changes.
1.9	03-Jul-1993	cgd	change interrupt vector names to begin with "X" rather than "V", so we're like every other BSD system on the planet...
1.8	03-Jul-1993	cgd	Unless INTR_DEBUG is set, don't report all of the "random" event types. also, unless INTR_DEBUG is set, make the internal branch labels for the interrupt code be local labels, so profiling works OK.
1.7	01-Jul-1993	andrew	Fixed a typo.
1.6	01-Jul-1993	mycroft	Fix Andrew's real bug, and put back the FAST_VECTOR changes.
1.5	30-Jun-1993	andrew	Backed out the changes to the FAST_VECTOR code that were made in the previous revision, as they apparently broke something.
1.4	27-Jun-1993	andrew	Neatened up the AUTO_EOI conditionals. FAST_VECTOR() now saves & restores the ES register, just to be on the safe side (since ES is used in some locore routines).
1.3	14-Jun-1993	mycroft	Add support for other networks than INET.
1.2	06-Jun-1993	cgd	apply patch 167, to fix some interrupt system bogosities
1.1	06-Jun-1993	cgd	incorporate Bruce Evans' interrupt changes, as hacked by Rod grimes, for patchkit patch 158. it appears to work well.
1.10.2.17	05-Dec-1993	mycroft	Use specific EOIs always.
1.10.2.16	05-Dec-1993	mycroft	Turn off special mask mode by default. It is clearly not supported enough.
1.10.2.15	11-Nov-1993	mycroft	Macroize interrupt entry and exit code.
1.10.2.14	01-Nov-1993	mycroft	Take advantage of special mask mode by leaving interrupts masked in ISR until they are serviced. No need to frob IMR.
1.10.2.13	01-Nov-1993	mycroft	imen --> imask
1.10.2.12	31-Oct-1993	mycroft	Reenable ICUs earlier in the interrupt sequence, and put the masking and unmasking code into macros.
1.10.2.11	29-Oct-1993	mycroft	Remove dummy ether_output().
1.10.2.10	27-Oct-1993	mycroft	Somehow I managed to delete this rather critical instruction.
1.10.2.9	27-Oct-1993	mycroft	This is a kluge.

1.126	13-Jan-1995	mycroft	Minor rearrangement.
1.125	13-Jan-1995	mycroft	Change the way sc_skip is used. Fix a bug in the (incomplete) DMA code. Add a new sc_blkno (which will be useful later).
1.124	07-Jan-1995	mycroft	Fix a race condition between normal I/O and wd_get_parms().
1.123	03-Jan-1995	mycroft	Add interrupt sharing types.

Other minor changes.
1.92	14-Oct-1994	cgd	move arch dependence to archs. clean up a bit. deal with weird MAXPARTITONS.

1.73	12-Mar-1994	mycroft	Prefix the busy-wait messages with `ignore this:' so people stop reporting it as a bug.
1.72	12-Mar-1994	mycroft	Fix problem with reading the disk label if it's not at the beginning of the disk.
1.71	12-Mar-1994	mycroft	Remove backward compatibility hacks for config(8), as they are no longer useful.
1.70	12-Mar-1994	mycroft	Update to match config(8).
1.69	11-Mar-1994	mycroft	Various: Put WDF_ERROR in the wdc_softc, to avoid gratuitously forcing non-active drives into single-sector mode on the next transfer. Arrange to wait for an interrupt after wdsetctlr(); this avoids long busy-wait delays, and gets rid of the `extra interrupt' messages (except for one immediately after autoconfig on some machines). Replace some uses of wdsetctlr() with simply lowering wd->sc_state; no point in forcing this immediately. Allow control operations to time out. Enable the warnings for long busy-wait delays by default. Some other minor things not worth mentioning.
1.68	10-Mar-1994	mycroft	Add a heuristic for detecting old config(8)s. This is very temporary.
1.67	10-Mar-1994	mycroft	Now that the disk probe routines are actually called, they need to return something.
1.66	10-Mar-1994	mycroft	More updates for new config.
1.65	10-Mar-1994	mycroft	Update for new config.
1.64	10-Mar-1994	mycroft	Cleanup to fit standard coding conventions, and many bugs fixed.
1.63	07-Mar-1994	mycroft	Some changes inspired by Bruce Evans's driver: Consolidate error reporting in one function. Actually use the dk_status and dk_error fields, and pass around only the error bit to avoid lots of unneeded assignments and tests. No functional differences.
1.62	07-Mar-1994	mycroft	Remove DKFL_QUIET.
1.61	06-Mar-1994	mycroft	DELAY() --> delay(). This is not a macro.
1.60	05-Mar-1994	mycroft	Move the drive select and various other things into wdcommand(), to avoid duplicating code.
1.59	04-Mar-1994	mycroft	Make sure we clear the interrupt when necessary. Why this isn't needed on my hardware is a mystery.
1.58	04-Mar-1994	mycroft	Add another missing splx().
1.57	04-Mar-1994	mycroft	Remember to splx() on some error conditions.
1.56	04-Mar-1994	mycroft	Start the timeout loop after we've decided there is a disk there.
1.55	04-Mar-1994	mycroft	De-ANSIfy. Move the timeout counter into struct disk. Remove unneeded args to wd[gs]etctlr(). Other minor changes.
1.54	03-Mar-1994	mycroft	Watch `seek complete' bit per IBM documentation. Clean up wdioctl(). Other minor cleanup.
1.53	02-Mar-1994	mycroft	Be more careful about clearing the controller and drive active flags.
1.52	02-Mar-1994	mycroft	Don't busy-wait for read or write completion.
1.51	02-Mar-1994	mycroft	Make wdc_wait() do an implicit wait_for_unbusy(). Pass structure pointers rahter than unit numbers where appropriate. Fix conflict if two drives have I/O pending at the same time. Add some more sanity checks. Some other minor cleanup.
1.50	26-Feb-1994	mycroft	Get the residual count right.
1.49	26-Feb-1994	mycroft	Clean up busy-wait code a little, and we need a special disksort() to skip over bufs in a combined transfer.
1.48	26-Feb-1994	mycroft	Fix bug from 1.43 correctly.
1.47	26-Feb-1994	mycroft	Fix typo.
1.46	26-Feb-1994	mycroft	Various cleanup, and fix last night's bug.
1.45	26-Feb-1994	mycroft	Fix typo.
1.44	26-Feb-1994	mycroft	Some more stylistic cleanup.
1.43	25-Feb-1994	mycroft	Fix an obvious bug that could stall the queue.

1.37	25-Feb-1994	mycroft	`We are the KNF. You will be assimilated.'
1.36	10-Feb-1994	mycroft	Back pointers are not useful for disksort().
1.35	09-Feb-1994	mycroft	All ioctl routines take a struct proc * now.
1.34	06-Feb-1994	mycroft	Remove another use of b_actl.
1.33	06-Feb-1994	mycroft	Use b_actf, not av_forw.
1.32	03-Jan-1994	mycroft	Inline all the [lr]cr[023]() `functions' in cpufunc.h.
1.31	03-Jan-1994	mycroft	Inline all the [lr]cr[023]() `functions' in cpufunc.h.
1.30	24-Dec-1993	ws	Correct dumping to WD (was destroyed by MACHINE_NONCONTIG code)
1.29	20-Dec-1993	mycroft	Canonicalize all #includes, and add pio.h where appropriate.
1.28	16-Dec-1993	mycroft	Eliminate reference to Maxmem.
1.27	13-Dec-1993	cgd	from Soeren Schmidt <sos@login.dkuug.dk>: Basically it does a timeout on lost interrupts, starting the operation again and logging and error message on the console. additionally fixes some of the (newer ending) while loops (that made it work with two IDE disks !)
1.26	01-Aug-1993	mycroft	branches: 1.26.2; Add RCS identifiers (this time on the correct side of the branch), and incorporate recent changes in netbsd-0-9 branch.
1.25	28-Jul-1993	cgd	incorporate changes from 0-9-base to 0-9-ALPHA
1.24	08-Jul-1993	deraadt	branches: 1.24.2; documentation error
1.23	07-Jul-1993	deraadt	added a timeout debugging mode to wd.c so that people can see how slow their controllers really are. Look for the WDCNDELAY_DEBUG definition.
1.22	07-Jul-1993	deraadt	ok, 5 second command timeouts..
1.21	06-Jul-1993	deraadt	number of changes: 1. controller reset code moved into one function, called from more places now. 2. more places now do timeouts. TIPCAT code turned on. 3. blew away the unused WDOPENLOCK test code. 4. delay is now done using WDCNDELAY repetitions of DELAY(25). Up to 2.5 second pause accepted from controller (some controllers have some commands that are actually this slow) 5. some of the old timeout code was really whacked.
1.20	05-Jul-1993	deraadt	added a missing {/} pair that barsoom seems to have taken out, but which the standard 386bsd 0.1 driver did have. This is for a piece of code in the bad block handling. found/fixed by hpeyerl.
1.19	05-Jul-1993	deraadt	all timeout code now calls DELAY() so the timeout delays are the same length on all processors. Where possible, the controller is reset if it times out.
1.18	05-Jul-1993	deraadt	increased the timeout inside wdcommand(). Some controllers impliment some commands very slowly.
1.17	18-Jun-1993	cgd	fix the divide-by-zero problem w/old disks. this patch is ws's "fault."
1.16	28-May-1993	deraadt	1. It is now possible to build a kernel that does not have a pc0 device driver. 2. "press any key to reboot" reads the key from the console. 3. wddump() still needs a non-blocking getc() routine (or flush)
1.15	22-May-1993	cgd	add rcsids to everything and clean up headers
1.14	20-May-1993	deraadt	First cut at cpu independent disklabels. There will be niggly little details no doubt..
1.13	10-May-1993	deraadt	This patch allows the wd device driver to tell how big the disks are on WD1007-derived controllers. In this example, wdc0 is a WD1007-clone, and wdc1 is a WD1003-clone. WD1007 controllers are generally ESDI and IDE controllers. wdc0 at 0x1f0-0x1f7 irq 14 on isa wd0 at wdc0 targ 0: 322MB 1224 cyl, 15 head, 36 sec <disktype> wdc1 at 0x170-0x17f irq 7 on isa wd2 at wdc1 targ 0: (unknown size) <disktype>
1.12	09-May-1993	deraadt	i thought i deleted this line before!
1.11	04-May-1993	deraadt	support for making dev->id_alive be set, this is for iostat to find disk devices. wee bit of a kludge. sub-device attach() routines must now return 1 for successful attach(), 0 otherwise. Other bsd's do this too..
1.10	18-Apr-1993	deraadt	slight code quality improvement. not related to the bug with very old controllers or disks! :-)
1.9	15-Apr-1993	deraadt	Once more: some changes to the ioconf.c structure. It will now handle devices hanging off controllers, any kind of controller. A device on isa0 is called at probe(self), then attach(self) A controller on isa0 is called at probe(self), then all it's children with defined unit numbers are initialized by calling attach(subdev); next all subdevices with unit ? are initialized by calling attach(sundev). Almost all device entry points is now like the vax/sun model (intr being the weird one)
1.8	15-Apr-1993	deraadt	wd driver would fail on calling wdgetctlr() for older drives and controllers. New behaviour is that if the standard method fails, try to recalibrate the drive. Success means the drive exists. patch by hpeyerl@novatel.cuc.ab.ca (who owns several of these historical artifacts)
1.7	12-Apr-1993	deraadt	new scsi subsystem. changes also in config/mkioconf.c & sys/scsi/*
1.6	09-Apr-1993	cgd	have probe return size of io space on successful return, rather than simply 1.
1.5	08-Apr-1993	deraadt	dmesg output at boottime now tries to print out information as soon as it is available. The output looks much more like Sunos.
1.4	06-Apr-1993	deraadt	ripped out a message
1.3	06-Apr-1993	deraadt	Mod-barsoom wd additions. config program + kernel config files changed too. fd support had to change slightly too.

Use dv_parent rather than storing another pointer to the fdc_softc in each fd_softc. Change disk label stuff for our kernel. icu.s: Make splx() and splnone() return previous cpl for now. isa.c: Minor autoconfig changes. isa.h: rtcin() is now nvram() and is declare in nvram.h. Make isaphysmem a caddr_t. pccons.c: XXXX: Maybe we should insist they open /dev/io now. timerreg.h: #define TIMER_NPORTS. wd.c: Delete unused wdnoreloc() and wddospart(), and use remaining two bits in unit number. struct disk --> struct wd_softc. struct board --> struct wdc_softc. Still needs much work.
