 1.29 30-Nov-2024  christos Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.
 1.28 12-Jul-2018  maxv branches: 1.28.36;
Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.
 1.27 24-Dec-2015  christos branches: 1.27.16; 1.27.18;
fenv for m68k
 1.26 17-Jul-2011  joerg branches: 1.26.12; 1.26.30;
Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
 1.25 04-Mar-2007  tsutsui Stop installing <machine/intr.h> on hp300. Suggested by simonb.
 1.24 09-Feb-2007  ad branches: 1.24.2;
Merge newlock2 to head.
 1.23 26-Jul-2006  drochner branches: 1.23.4;
don't install <machine/db_machdep.h>, this is kernel only
 1.22 01-Jul-2006  tsutsui No need to install autoconf.h.
 1.21 11-Dec-2005  christos branches: 1.21.4; 1.21.8; 1.21.16;
merge ktrace-lwp.
 1.20 08-May-2004  kleink branches: 1.20.12;
Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.
 1.19 17-Jan-2003  thorpej branches: 1.19.2;
Merge the nathanw_sa branch.
 1.18 26-Nov-2002  lukem Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.
 1.17 07-Aug-2002  briggs Implement pmc(9) -- An interface to hardware performance monitoring
counters. These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface. Initially, the Intel XScale
counters are the only ones supported.
 1.16 28-Nov-2001  kleink branches: 1.16.8;
No point in installing svr4_machdep.h.
 1.15 15-Apr-2001  kleink branches: 1.15.2; 1.15.8;
Add definitions of C99 integer format conversion macros.
XXX Fastest minimum-width integer types haven't been decided upon yet.
 1.14 15-Apr-2001  kleink Add definitions of C99 specified-width integer type limits.
XXX Fastest minimum-width integer types haven't been decided upon yet.
 1.13 14-Apr-2001  kleink Add definitions of C99 integer constant macros.
Tidy Makefiles up a little.
 1.12 14-Apr-2001  kleink Add definitions of C99 minimum-width and greatest-width integer types.
XXX Fastest minimum-width integer types haven't been decided upon yet.
 1.11 26-Jun-2000  kleink branches: 1.11.2;
Add <machine/int_types.h>, which provides namespace-pure definitions
of exact-width integer types.
 1.10 29-Apr-2000  thorpej Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
 1.9 17-Mar-2000  tron Install "machineendian_machdep.h".
 1.8 23-Dec-1999  kleink C99: Define a NAN macro in <math.h> which evaulates to a constant expression of
a single-precision quiet NaN; only to be defined on platforms that do support
this value.
 1.7 21-Dec-1999  frueauf As per Chris G. Demetriou <cgd@netbsd.org> don't install
loadfile_machdep.h into /usr/include/hp300/, instead create a
link for machine and hp300 in ${.OBJDIR} like
sys/arch/alpha/stand/Makefile.buildboot does for alpha.
 1.6 20-Dec-1999  frueauf Add loadfile_machdep.h to includes to be installed - this makes
sys/arch/hp300/stand/* compile again.
 1.5 19-Apr-1999  kleink branches: 1.5.2; 1.5.8;
Add COMPAT_SVR4 for m68k.
 1.4 15-Mar-1999  minoura branches: 1.4.4;
Pullin m68k/ieee.h.
 1.3 15-Jan-1999  bouyer Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
 1.2 12-Jul-1998  veego Add elf_machdep.h to the INCS list.
 1.1 12-Jun-1998  cgd Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
 1.4.4.1 21-Jun-1999  thorpej Sync w/ -current.
 1.5.8.1 27-Dec-1999  wrstuden Pull up to last week's -current.

 1.5.2.1 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.

 1.5 07-May-2019  kamil Switch all users (except ia64) of custom machine/ansi.h to common_ansi.h

Deduplicate the code among ports and poll definitions of types
directly from a compiler.

This fixes miscompilation of certain programs that instruct compilers
to generate code for different types. This bug has been detected with
-fshort-wchar in EFI firmware.

Proposed and discussed on a mailing list (twice).

Itanium uses custom !ELF fallback switch, temporarily leave it as it is.

 1.1 23-Jan-1994  cgd stub
 1.13 20-Apr-2014  tsutsui Add proper consinit(9) support for sti(4) at sgc framebuffer on hp300.

The cnattach functions for sti(4) and service switch check method
for 425e in com_frodo.c are taken from OpenBSD.
The strategy how to choose the console device in hp300_cninit() is
quite diverged from 4.4BSD and OpenBSD so it's tweaked by me.

Also put several changes in sti_sgc.c to reduce diffs from OpenBSD/hp300.

Tested on 425e and 362 (which still uses gendiofb(4), not sti(4)).

XXX: sti(4) requires uvm_km_alloc(9) and uvm_map_protect(9)
to copy and call ROM functions on the executable memory region, so
it can be called before UVM and related initializations are complete.
Probably it's time to consider about MI "deferred consinit()" API
in init_main.c (or elsewhere) for modern complicated VM system...
 1.12 06-Feb-2011  tsutsui branches: 1.12.4; 1.12.10; 1.12.14; 1.12.18; 1.12.28;
Switch NetBSD/hp300 to wscons with rasops. Simply ported from OpenBSD/hp300.

- Only A1416 Kathmandu (topcat) framebuffer on 425t is tested, but
all other variants (TigerShark, Hyperion, DaVinci, GatorBox, Renaissance)
should also work if they are working on OpenBSD/hp300.
- sti(4) and SGC bus support are not pulled because I don't have 425e
and I can't confirm that 362 and 382 actually have SGC bus.
(I'll commit a DIO based dumb driver for 362 and 382 framebuffers later)
- Xorg server with wsfb driver will also be integrated soon
once after keycode with NoSymbol problem is addressed.
(We have to re-think what code should be used on WSDISPLAY_COMPAT_RAWKBD)
- MI HIL keyboard and mouse drivers are working fine though
cngetc via hilkbd has some problem (still we can input commands).
- No old HP-UX like HIL ioctl compatibility (we removed COMPAT_HPUX anyway).
grfinfo(8) and hilinfo(8) will be removed shortly.

Demonstrated on NetBSD booth at Open Source Conference 2011 Kagawa.

Replace resource map usage with extent maps.
 1.7 14-Dec-2001  gmcgarry Update the console attach interface now that bus_space is available.
Basically means that hardware drivers with console attachments are
now largely machine independent.
 1.6 06-Oct-1998  thorpej branches: 1.6.26; 1.6.30;

 1.3 03-Mar-1996  thorpej Fix logic errors in new console probe code that caused framebuffers
outside of "internal i/o" space to not even have a chance at console-hood.
Fix tested by Thorsten Frueauf <frueauf@ira.uka.de>, and offered with
my sincerest apologies that the bug ever existed in the first place.
 1.2 28-Feb-1996  thorpej Copyright assigned to The NetBSD Foundation.
 1.1 24-Feb-1996  thorpej Completely rework how the console is probed. Console probing no longer

Add sti at sgc framebuffer.
Ported from OpenBSD by kiyohara@.
Fix a botch on switching from apci (and dca) to MI com(4) 10 years ago.
I.e. fix apci device address per FRODO_BASE macro change
in frodoreg.h rev 1.2. Now bootloader works with serial console
on HP425e (which has only com at frodo).
Thanks to miod@openbsd for providing his 425e.
Add sti(4) at sgc screen console support. From (the late) OpenBSD/hp300.
Tested on HP9000/425e, which was sent from Miod Vallat and
demonstrated at Open Source unConference 2014 Kagawa.
Check the service switch on 425e to select apci serial console.
Taken from OpenBSD/hp300. See the following comment for details:
> * Check the service switch. On the 425e, this is a physical
> * switch, unlike other frodo-based machines, so we can use it
> * as a serial vs internal video selector, since the PROM can not
> * be configured for serial console.
Add proper RealTime Clock support for HP9000/425e.
As the OpenBSD/hp300 page says 425e doesn't have the traditional
RTC at intio (as it also lacks DCA 16550 serial at intio?),
but after a few hour investigation it turns out that
425e uses mc146818 compatible calendar clock in
the Apollo "frodo" utility chip and the frodo chip on
425e actually has the 32kHz OSC and is actually backed up
by the onboard lithium battery.
Tested on HP425e (with mcclock) and HP362 (with old rtc).
Add RTC support for HP9000/425e to bootloader too.
Also put several cleanup:
- make local functions and variables static
- use proper variable types
- some KNF
Note it turns out that extreme slowness of netboot on hp300 is
caused by the too slow access of the traditional RTC chip at intio
(i.e. netboot on 425e is so much faster than others). Oh well.
Add proper consinit(9) support for sti(4) at sgc framebuffer on hp300.
The cnattach functions for sti(4) and service switch check method
for 425e in com_frodo.c are taken from OpenBSD.
The strategy how to choose the console device in hp300_cninit() is
quite diverged from 4.4BSD and OpenBSD so it's tweaked by me.
Also put several changes in sti_sgc.c to reduce diffs from OpenBSD/hp300.
Tested on 425e and 362 (which still uses gendiofb(4), not sti(4)).
XXX: sti(4) requires uvm_km_alloc(9) and uvm_map_protect(9)
to copy and call ROM functions on the executable memory region, so
it can be called before UVM and related initializations are complete.
Probably it's time to consider about MI "deferred consinit()" API
in init_main.c (or elsewhere) for modern complicated VM system...
Also fix the apci device address in dnkbd.c as apci.c rev 1.12:
http://mail-index.netbsd.org/source-changes/2014/04/10/msg053940.html
Finally dnkbd(4) is confirmed working at least on bootloader.
Thanks again to Miod Vallat.
Make the Apollo Domain keyboard actually work.
Tested on HP9000/425e and the keyboard model A1630-82001 R2 (RX-60857-HW)
provided by Miod Vallat. Mouse support needs more work.
Pull random notes on the Apollo Domain keyboard from ancient PR/3528.
Bump versions to denote recent 425e related changes.
Probe mcclock only on 425e to avoid an extra "not configured" message.
Add and enable sti(4) at sgc in install kernels for 425e.
Tested on both serial console and framebuffer console.

 1.1 14-Dec-1999  thorpej Add a bootinfo facility, as is used on i386 and pmax, ports. We expect
the bootinfo to be located in the first page of kernel text (which has
been zero-filled for a Very Long Time to allow us to unmap KVA 0); the
boot loader will place it there after loading the kernel image.

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.

still include <machine/byte_swap.h> and define macros for some of
the bswap*() functions.
 1.1 15-Jan-1999  bouyer Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

Add dummy bus_dma(9) typedefs (enabled by __HAVE_NO_BUS_DMA) in <sys/bus.h>
for ports which don't bother to have unnecessary bus_dma(9) implementation
to appease MI driver modules that require bus_dma_tag_t.

For amiga, move <m68k/bus_dma.h> inclusion from <machine/pci_machdep.h>
to <machine/bus.h> since amiga will want actual bus_dma(9) in future
for PCI devices.

installboot(8): formatting improvements

Use Ar foo instead of <foo>; this is mdoc.

Other formatting tweaks.
installboot(8): fix up markup

Don't overuse .Sy - when everything is highlighted, nothing is. Use
.Ic for options &c to get correct PostScript output (both are bold in
plain text).

Use Aq Ar inside .Pa, as both Pa and Ar are rendered as underscored
text in plain text output, and the distinction is lost.

Don't set examples in bold, but give them .Pp space around - they are
much easier to read this way.

Use consistent -width in FILES.

PR/57909: Jan-Benedict Glaw: Don't include (build) timestamp when doing a
reproducible build
fix usage string, improve error handling.
add missing chunk for repro-build. fix gcc warnings.
avoid stringop truncation, fix copyright string to prevent assembler warnings.

Fix build as a tool (Jan-Benedict Glaw)

Fix integer overflow of strtol(3) for "loadpoint" address on ILP32 hosts.

This strtol(3) was introduced in rev 1.12 for PR/57909 after netbsd-10,
but it returns LONG_MAX (0x7FFFFFFF) for 0xFFF00000 on ILP32 hosts and
the wrong loadpoint causes "NOT ENOUGH MEMORY" error by the BOOTROMs
on loading uboot.lif on (at least) my 9000/360 and 9000/425t.

Misc cosmetic changes for mostly readability.
- KNF and add some newlines per blocks
- define and use proper bintobcd() macro
- make local functions and variables static

The same uboot.lif binaries are generated.

Rename ${PROGAOUT} -> ${PROGELF} to reflect reality.
Use proper signedness for the LIF file system data structures.

Ancient 4.3BSD used short and int for location, file size, file type,
and addresses etc. but all of them should be unsigned.

Also rename several variables and add comments for readability.
The LIF file system info can be found in "The HPDir Project" page:
https://www.hp9845.net/9845/projects/hpdir/
The same uboot.lif binaries are generated.

Add a preliminary CD boot support to uboot for preparation of PR/54455.
Briefly tested on mame, but not enalbed yet.

Recognize SCSI CD-ROM devices as a booted device properly.

Necessary for PR port-hp300/54455, to boot an md root root RAMDISK

kernel from CD-ROM without "WARNING: can't find match for bootdev:"
prompt.

Sync with src/sys/arch/hp300/stand/mkboot/volhdr.h rev 1.6.
https://mail-index.netbsd.org/source-changes/2024/05/07/msg151195.html

Use proper signedness for the LIF file system data structures.
mkboot should use this MI <sys/bootblock.h> and volhdr.h should
be removed soon.

Use MI <sys/bootblock.h> to refer LIF filesystem structures.
This should have been done when LIF definitions were initially added
to <sys/bootblock.h> for MI installboot(8).

Enable SUPPORT_CD on uboot.

Make cd9660_util.c usable in userland tools like installboot(8).

This was partially done for src/distrib/cdrom/macppc_installboot,
but more strict prototypes are necessary for native binary builds.

Install cd9660 related system headers for tools installboot(8) builds.

Reorder function prototypes per source files.

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

Put a RAMDISK kernel and SYS_UBOOT into hp300 installcd to make it bootable.

This should finally close PR/54455.

Appease warnings on building tools/installboot on Cygwin.

This file, which will be included by <sys/cdefs.h>, will contain macros
such as __warn_references() and __weak_reference() which are actually
machine dependant. This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".

 1.71 18-Feb-2019  thorpej Refactor the 68040 writeback() from each m68k port's trap handler into a
shared copy: m68040_writeback(). It is essentially a copy of the Atari
version, with some minor cosmetic tweaks and one small performance optimization
from the mvme68k port.

Tested by rjs@ on a Quadra 950. (Thanks!)

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.

 1.44 28-Aug-2004  thorpej De-__P
 1.43 04-Jan-2004  jdolecek Rearrange process exit path to avoid need to free resources from different
process context ('reaper').

From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
as FPU state), and is the last potentially blocking operation;
all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
for both 'process' and 'lwp' exit

uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.

MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.

g/c now unneeded routines and variables, including the reaper kernel thread

 1.34 26-May-2000  thorpej branches: 1.34.2;
First sweep at scheduler state cleanup. Collect MI scheduler
state into global and per-CPU scheduler state:

- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.

- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).

- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.

- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.

Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

 1.30 11-Nov-1998  thorpej Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the

- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

 1.28 13-Feb-1998  scottr Avoid declaring the "astpending" and "want_resched" globals in cpu.h,
as this breaks C++ code that happens to indirectly include this header.
Both Matthias Scheler and I noticed this, independently.

This problem notably does not affect the atari and sun3/sun3x ports,
which have already implemented a similar solution.
 1.27 26-Oct-1997  is Make these compile after m68k/m68k.h 1.4->1.5.

- Move a bunch of hp300 SPU-specific stuff out of cpu.h, and place it
in new hp300spu.h file. This includes the code that associates
model number with cpu/mmu/cache combinations.
- Define "mmuid" constants for several models, derived from code
provided by Mike Smith.
 1.24 14-Apr-1997  thorpej Rearrange the interrupt code slightly:
- place all interrupt-related macros, prototypes, etc. into <machine/intr.h>,
like other ports.
- rename isrlink/isrunlink/isrinit, etc. intr_establish/intr_disestablish/
intr_init, etc., and move to intr.c for naming consistency.
- don't call intr_init() twice.
 1.23 09-Apr-1997  thorpej regdump() is prototyped in m68k/cpu.h now.

 1.16 21-Dec-1995  mycroft Remove deprecated cpu_setstack().
 1.15 11-Dec-1995  thorpej Rather than using individual HP300 model names, map those model names to
properties such as "M68040" and "M68K_MMU_MOTOROLA", used to conditionally
compile code. This is more in-line with now the other m68k ports do it,
and makes it much easier to find "common ground" among them.

In locore.s, use the MMU-type constants defined my <machine/cpu.h> rather
than "expanded" values.

Because HP300-model names are mapped to CPU/MMU combinations in
<machine/cpu.h>, no change to kernel configuration will be necessary.
 1.14 28-Jun-1995  cgd remove unused cpu_exec() definitions. moved "broken swap" markers, for

installboot(8): formatting improvements

Use Ar foo instead of <foo>; this is mdoc.

Other formatting tweaks.
installboot(8): fix up markup

Don't overuse .Sy - when everything is highlighted, nothing is. Use
.Ic for options &c to get correct PostScript output (both are bold in
plain text).

Use Aq Ar inside .Pa, as both Pa and Ar are rendered as underscored
text in plain text output, and the distinction is lost.

Don't set examples in bold, but give them .Pp space around - they are
much easier to read this way.

Use consistent -width in FILES.

PR/57909: Jan-Benedict Glaw: Don't include (build) timestamp when doing a
reproducible build
fix usage string, improve error handling.
add missing chunk for repro-build. fix gcc warnings.
avoid stringop truncation, fix copyright string to prevent assembler warnings.

Fix build as a tool (Jan-Benedict Glaw)

Fix integer overflow of strtol(3) for "loadpoint" address on ILP32 hosts.

This strtol(3) was introduced in rev 1.12 for PR/57909 after netbsd-10,
but it returns LONG_MAX (0x7FFFFFFF) for 0xFFF00000 on ILP32 hosts and
the wrong loadpoint causes "NOT ENOUGH MEMORY" error by the BOOTROMs
on loading uboot.lif on (at least) my 9000/360 and 9000/425t.

Misc cosmetic changes for mostly readability.
- KNF and add some newlines per blocks
- define and use proper bintobcd() macro
- make local functions and variables static

The same uboot.lif binaries are generated.

Rename ${PROGAOUT} -> ${PROGELF} to reflect reality.
Use proper signedness for the LIF file system data structures.

Ancient 4.3BSD used short and int for location, file size, file type,
and addresses etc. but all of them should be unsigned.

Also rename several variables and add comments for readability.
The LIF file system info can be found in "The HPDir Project" page:
https://www.hp9845.net/9845/projects/hpdir/
The same uboot.lif binaries are generated.

Add a preliminary CD boot support to uboot for preparation of PR/54455.
Briefly tested on mame, but not enalbed yet.

Recognize SCSI CD-ROM devices as a booted device properly.

Necessary for PR port-hp300/54455, to boot an md root root RAMDISK

kernel from CD-ROM without "WARNING: can't find match for bootdev:"
prompt.

Sync with src/sys/arch/hp300/stand/mkboot/volhdr.h rev 1.6.
https://mail-index.netbsd.org/source-changes/2024/05/07/msg151195.html

Use proper signedness for the LIF file system data structures.
mkboot should use this MI <sys/bootblock.h> and volhdr.h should
be removed soon.

Use MI <sys/bootblock.h> to refer LIF filesystem structures.
This should have been done when LIF definitions were initially added
to <sys/bootblock.h> for MI installboot(8).

Enable SUPPORT_CD on uboot.

Make cd9660_util.c usable in userland tools like installboot(8).

This was partially done for src/distrib/cdrom/macppc_installboot,
but more strict prototypes are necessary for native binary builds.

Install cd9660 related system headers for tools installboot(8) builds.

Reorder function prototypes per source files.

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

Put a RAMDISK kernel and SYS_UBOOT into hp300 installcd to make it bootable.

This should finally close PR/54455.

all other variants (TigerShark, Hyperion, DaVinci, GatorBox, Renaissance)
should also work if they are working on OpenBSD/hp300.
- sti(4) and SGC bus support are not pulled because I don't have 425e
and I can't confirm that 362 and 382 actually have SGC bus.
(I'll commit a DIO based dumb driver for 362 and 382 framebuffers later)
- Xorg server with wsfb driver will also be integrated soon
once after keycode with NoSymbol problem is addressed.
(We have to re-think what code should be used on WSDISPLAY_COMPAT_RAWKBD)
- MI HIL keyboard and mouse drivers are working fine though
cngetc via hilkbd has some problem (still we can input commands).
- No old HP-UX like HIL ioctl compatibility (we removed COMPAT_HPUX anyway).
grfinfo(8) and hilinfo(8) will be removed shortly.

 1.16 18-Jan-2024  thorpej Make the M68K_MMU_* defines real kernel options, available in opt_m68k_arch.h.
For 68030, 68040, and 68060, infer M68K_MMU_MOTOROLA. For 68010 and 68020, it
must be an explicit option (set in std.${MACHINE} or, in the case of hp300,
inferred from the specific model option).
 1.15 18-Jan-2024  thorpej Rather than testing for and defining the M680x0 CPU option in
hp300spu.h, make the individual model options (e.g. HP320, HP425,
etc.) declare a dependency on the correponding M680x0 options.
This makes them appear correctly in opt_m68k_arch.h rather than
having to pull in all of <machine/cpu.h>.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
 1.15 29-Jun-2003  thorpej Adapt to ktrace/lwp changes.
 1.14 28-Jun-2003  darrenr Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
 1.13 17-Jan-2003  thorpej Merge the nathanw_sa branch.
 1.12 04-Jul-2002  thorpej Add kernel support for having userland provide the signal trampoline:

* struct sigacts gets a new sigact_sigdesc structure, which has the
sigaction and the trampoline/version. Version 0 means "legacy kernel
provided trampoline". Other versions are coordinated with machine-
dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions. Instead,
sendsig() looks up the handler by peeking in the sigacts for the
process getting the signal (since it has to look in there for the
trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later. Kernel
version not bumped; we will ride the 1.6C bump made recently.

Garbage-collect a bunch of _very_ hp300-specific code, most of which

for the DMA controller by tracking all of the DIO devices that have
"ISRPRI_BIO" interrupt handlers, and finding the highest auto-vector
level among them and informing the DMA controller.

Previously, in a post-flattening world, the DMA controller was always
told to interrupt at lev5, which is fine I guess although definitely not
ideal, but would not work on aaaancient HP320 Rev A DMA boards. To that
effect, print a warning if a Rev B DMA board ends up at ipl != 3 (we can't
differentiate between a Rev A and a Rev B board).
 1.37 16-Jan-2024  thorpej Switch hp300 over to the common interrupt dispatch code.

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.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

sys/rwlock.h: Make this more self-contained for bool.

machine/mutex.h: Sprinkle includes so this can be used by crash(8).

ddb: New `show all tstiles' command.
Shows who's waiting for which locks and what the owner is up to.

Include psl.h for ipl_cookie_t if __MUTEX_PRIVATE

sys: Rip <sys/resourcevar.h> out of <uvm/uvm_param.h>.

And thus out of <sys/param.h>, which is exceedingly overused and
fragile and delenda est.

Should fix (some) issues with the recent inclusion of machine/lock.h
in various machine/mutex.h files.

arm/mutex.h: Need machine/intr.h, machine/lock.h.

For ipl_cookie_t and __cpu_simple_lock_t.
evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL.

Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which
should really be fixed.
opencrypto/cryptodev.h: Fix includes.
- Move sys/condvar.h under #ifdef _KERNEL.
- Add some other necessary includes and forward declarations.
- Sort.

hp300/intr.h: Fix missing includes.
linux/idr.h: Need <sys/mutex.h> for kmutex_t.
amiga/intr.h: Don't define spl*() functions if !_KERNEL.

This is used by crash(8) now, and what's important is ipl_cookie_t.
cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8).
cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER.

Probably not necessary but let's be a little more cautious about
this.

atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8).

arm/cpu.h: Need sys/param.h for COHERENCY_UNIT.

Nix machine/param.h -- not meant to be used directly, pulled in by
sys/param.h.

Move the definition of ipl_cookie_t out of the kernel-only sections,
some _KMEMUSER applications need it.

ddb: Cast pointer to uintptr_t first before db_expr_t.

hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

news68k/intr.h: Fix includes. Put some definitions under _KERNEL.

next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

sys/ksem.h: Hack around fstat(8) abuse of _KERNEL.

sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).

x68k/intr.h: Put functions under _KERNEL so crash(8) can use this.

Make ipl_cookie_t visible for _KMEMUSER userland applications.

fix editor mishap in previous

Explicitly include <sys/mutex.h> for kmutex_t.

Replace kmutex_t * (which may be undefined here) with struct kmutex *,
suggested by Taylor.

hp300/intr.h: Put most of this under #ifdef _KERNEL.
Only ipl_cookie_t really needs to be exposed now, for crash(8).

mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
Make inclusion of sys/intr.h explicit for spl*.

fix hppa and vax builds.

machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in
sys/types.h. avoids cpu_data.h vs sched.h include order issues.

move the hppa ipl_t typedef with the moved usage of it.
machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.

Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which
always comes from sys/types.h. And, really, sys/types.h (or at least
sys/stdint.h) is needed for uintN_t and uintptr_t.

ddb: Cast pointer to uintptr_t, then to db_expr_t.
Avoids warnings about conversion between pointer and integer of
different size on some architectures.

re-fix hppa builds.

this file uses __cpu_simple_lock(), not just the underlying type,
so it does need machine/lock.h.

Break cycle by using `struct kmutex *' instead of `kmutex_t *'.
sys/sched.h included sys/mutex.h
which includes sys/intr.h
which includes machine/intr.h
which on cats includes arm/footbridge/footbridge_intr.h
which includes arm/cpu.h
which includes sys/cpu_data.h
which includes sys/sched.h

But there was never any real need for sys/mutex.h in sys/sched.h,
because it only uses pointers to the opaque struct kmutex. Cycle
broken by using `struct kmutex *' instead of pulling in sys/mutex.h
for the definition of kmutex_t.

Side effect: This revealed that sys/cpu_data.h needed sys/intr.h
(which was pulled in accidentally by sys/mutex.h via sys/sched.h) for
SOFTINT_COUNT. Also revealed some other machine/cpu.h header files
were missing includes of sys/mutex.h for kmutex_t.

ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t.

explicitly include no longer implicitly included sys/mutex.h.

arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz.
Sidesteps namespace collision with `#define bits ...' in net/zlib.c.

complete the previous - there were two calls to find_first_bit() to fix.

arm/xscale: Missed a spot with previous find_first_bit commit.

evbarm/g42xxeb: Fix off-by-one in previous.

The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x),
which is equivalent to fls32(x) - 1, not to fls32(x).

Note that fls32 is 1-based and returns 0 for x=0.

Require that each each MACHINE/MACHINE_ARCH supply a lock.h. This file
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.

These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.

Tested on atari, hp300, and news68k.
 1.50 09-Dec-2009  tsutsui Fix wrong NBSEG values for all hp300 pmap derived m68k ports.
They were incorrect since 1997 on amiga and atari, and since 2002
on other ports, but fortunately they don't look so fatal.

Anyway, these values will be moved into <m68k/pmap_motorola.h> soon
since they are quite pmap implementation dependent.

compile code. This is more in-line with now the other m68k ports do it,
and makes it much easier to find "common ground" among them.

In locore.s, use the MMU-type constants defined my <machine/cpu.h> rather

Because HP300-model names are mapped to CPU/MMU combinations in

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

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.

 1.1 13-Jan-2024  thorpej Switch hp300 over to the common m68k vector table.
 1.41 01-Feb-2020  tsutsui Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).

Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
but each port uses different PAGE_SIZE value (4096 or 8192)
due to historical reasons.
- Currently module(7) binaries are built per each port so
all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
support m68k ports where PAGE_SIZE==8192.
(though this would affect only if static binaries built on
4k page hosts are executed on 8k page hosts)

To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.
For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.

Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:
https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035

 1.25 29-Apr-2001  thorpej Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

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.

Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).

Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
but each port uses different PAGE_SIZE value (4096 or 8192)
due to historical reasons.
- Currently module(7) binaries are built per each port so
all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
support m68k ports where PAGE_SIZE==8192.
(though this would affect only if static binaries built on
4k page hosts are executed on 8k page hosts)

To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.

For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.

Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:
https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035
https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954

Should be pulled up to netbsd-9.
