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.

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

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.

It turned out that using some Open Firmware routines causes the system
freeze after calling OF_quiesce().

This is why setting color palette crash the system for some Power Mac G5
models, like PowerMac11,2.

Therefore, stop using color-palette and backlight callbacks for genfb(4)
in this case.

Also, postpone OF_quiesce() after rascons_init_rasops(), and initialize
color palette there if OF is going to be quiesced and color depth is 8.

Now, color palette for wscons is initialized correctly for PowerMac11,2.

workaround a problem with the pegasos firmware interface:
attempting to use /dev/openfirm on this machine hangs hard.

this isn't a new problem, and i've been meaning to try to
figure it out for years, but it's become a problem since
the xf86-video-radeon driver gained code to look for the
macppc model using this interface.

this is why xorg-server 1.18 and 1.20 hang recently on the
pegasosII.


this change is fairly ugly but i couldn't think of a less
ugly method to avoid /dev/openfirm working just on this
one platform. introduce new __OPENFIRMIO_OPEN_CHECK_BROKEN
macro and associated __openfirmio_open_check_broken(), and
use them in the new openfirmopen() to fail opens.

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.

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.

Rename IPL_IMP -> IPL_VM.

Perform a rototill of the powerpc code. Mandate use of SPRG0 to store
a pointer to current cpu's cpu_info structure. Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make
ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK
to std.<platform>. Change faultbuf to a struct instead of an array.

On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.

Make macppc compile by default with -Wall -Wmissing-prototype in addition

Merge my MP tree. At this point, Daystar dual 604 card (i.e. Power Macintosh

branches: 1.10.2;
Make sure everybody has an splvm() and equate it with splimp() (splimp()
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).

Make spl functions no-inline. This saves size and even it runs faster on
some systems.

Add spllock(). See spl(9) for details.

Make sure we provide splsched() as described in spl(9).

Change ICU_LEN to 64.

branches: 1.5.2;
Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

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).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.

Count clock interrupts.

Assign my copyrights to TNF.

Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.

On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

- When starting the boot program, cache a bunch of OFW frequently used
ihandles / phandles, rather than fetching them all the time.
- Change the signature of OF_call_method() to take an array of cells for
the inputs and outputs, rather than using variadic arguments. This
makes it much easier to use OF_call_method() when the format of the
arguments passed to a given method are determined at run-time
(due to e.g. #address-cells).
- Properly inform OpenFirmware where the kernel is loaded by using
"claim" on /chosen/memory and, if running in virtual-mode, using
"claim" on /chosen/mmu to reserve the VA, and "map" on /chosen/mmu
to enter the translation. (The kernel is still always mapped VA==PA.)

__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

the bridge's location.

Define preprocessor symbols (__HAVE_OPENFIRMWARE_VARIANT_AAPL and
__HAVE_OPENFIRMWARE_VARIANT_SUNW) that lets generic OpenFirmware
code deal with differences / quirks among implementation variants.

branches: 1.14.70;
Enable new-style <sys/bus.h> on several PowerPC ports supporting PCI
buses. Make non-inline implementations of bus_space(9) and bus_dma(9)
routines and move them to appropriate .c files.

This may leave amigappc in a bad state, sorry. Fortunately, it will be
easy to repair by imitating the bus.h -> bus_{defs,funcs}.h split in
some other PowerPC port.

Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants,
remove the conditionals and the code associated with the undef case.

branches: 1.12.2; 1.12.8;
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.

branches: 1.11.10;
Generic soft interrupts are mandatory.

branches: 1.10.8; 1.10.16;
add timecounter support, mostly from prep.

branches: 1.9.2;
Convert macppc to generic todr. ok macallan@.

branches: 1.8.8; 1.8.20;
merge ktrace-lwp.

branches: 1.7.16;
Enable generic software interrupts on macppc.

branches: 1.6.16;
Use "#define<tab>".

branches: 1.5.8; 1.5.12;
Remove __BROKEN_DK_ESTABLISH.

Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc. Those
platforms should be changed to use device_register(). In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

Use device_register to find the boot device more reliably. Should now work
on anything it's possible to boot from that we have a driver for.

branches: 1.2.14;
Use arch/powerpc/.

Initial import of macppc port.

Not used.

avoid lint error.

Initial import of macppc port.

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.

Use arch/powerpc/.

Initial import of macppc port.

Don't export USER_SR if _MODULE is defined.
Add a common <powerpc/vmparam.h> like we have for <powerpc/pmap.h>

branches: 1.23.140;
Rename PPC_MPC6XX to PPC_OEA (and any mpc6xx reference to oea).

Remove OLDPMAP support.

Use __LDPGSZ (which must be == USRTEXT) as the text address for a.out
executables, and eliminate the USRTEXT constant, which was only used
by the a.out exec code.

switch all mpc6xx powerpc ports to NEWPMAP by default.
the old pmap is still available with the OLDPMAP option.

MAXSLP is defined to be a machine-independent scheduling parameter,
so move it into sys/param.h.

branches: 1.18.2; 1.18.8;
Make the new pmap optional. Use the old (stable!) pmap by default.

Changes new pmap, common param.h, vmparam.h, and moved includes.

Per discussion w/ chuck and chuck, restructure the md page stuff
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

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.

Remove PAGER_MAP_SIZE definition -- use default value. Instead, decrease
VM_MAX_KERNEL_BUF.

branches: 1.13.2;
Increase all of the limits.

Reduce PAGER_MAP_SIZE to 4MB.

branches: 1.11.4;
Update for the NKMEMPAGES changes.

CL* discarding.

branches: 1.9.2; 1.9.8;
Add VM_MAX_KERNEL_BUF definition.

Now that we have direct-mapped pool pages, we can garbage-collect VM_MBUF_SIZE
and don't need to allocate mb_map.

branches: 1.7.2; 1.7.4;
VM_MBUF_SIZE is in terms of MCLBYTES, not CLBYTES.

Increase default data size to compile libbfd without `virtual memory
exhausted'. Suggested by Scott Reynolds.

MNN is no longer optional

vm_offset_t --> [pv]addr_t.

Change VM_MAXUSER_ADDRESS to 0x7ffff000.

Add support for UVM and MACHINE_NEW_NONCONTIG.

Initial import of macppc port.

Add latent generic soft interrupt support.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

branches: 1.6.2;
Add prototypes for ZS_TXDMA functions.
XXX Maybe we should have DMA hooks in MI z8530tty.

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.

add support for kgdb over zs

branches: 1.3.26; 1.3.30;
Back out previous change.

Enable 115200 and (untested)230400 bps.
