macppc/machdep: Correctly disable have_backlight for ofw_quiesce
instead of have_palette (copy-paste bug by myself).

macppc/machdep: Correctly disable have_backlight for ofw_quiesce

instead of have_palette (copy-paste bug by myself).

Move the at-shutdown call to resettodr() from cpu_reboot() to kern_reboot().

It's a small step, but it's a step.

cpu_reboot: use cpu_halt_others() instead of a (simple) open coded
version of it.

switch G5 iMacs to full speed

Un-do a bunch of misguided code sharing.  It's not really shared if it's
full of platform-specific #ifdefs:
- ofwoea_batinit() is gone; just do what's needed early in macppc / ofppc
  initppc() functions.
- Get a bunch of Mac-specific stuff out of ofwoea_initppc().

There is not much point in of_compatible() returning -1 for "no match"
and >= 0 for "match".  Just make it return 0 for "no match" and >0 for
"match" so it can be treated like a boolean expression.

As such of_match_compatible() (a wrapper around of_compatible()) is now
obsolete, and will be removed once all call sites are converted to an
appropriate replacement.

Adapt to new proplib API

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.

work around a bug in some (all?) nvidia OF ROMs:
the color! method always changes only the palette registers associated with the

DVI or ADC.
Don't enable cmap_callback when we find out we're on port 2 of an nvidia card,
that way genfb won't try to use R3G3B2 colours and assume something resembling
an ANSI palette which will at least gives us something usable, as opposed to
black on mostly black.

Update haad-dm branch to haad-dm-base2.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled.  So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks().  Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown().  No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown().  I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that.  Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

get rid of heathrow_FCR

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Apply a set of patches from Frank Wille to make the genfb attachment work

Also, introduce a model_init function.

move ofb_cons.c from macppc/dev to powerpc/oea and rename it to rascons.
This gets rid of some naming confusion, and makes it OFW-MI rather than

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.

Move a bunch of the macppc SMP code out of macppc, and down into the
generic OEA code.  Add a set of md callbacks into these shared routines,
that any oeappc SMP machine needs to provide.  This allows for generally
shared SMP startup code, but still allows for machine-specific
differences in the setup and kicking of the new CPU.

Convert macppc to this new layout.  Tested by Macallan.

Add an initial attempt at SMP to prep.  Tested on UP machine only,
untested on SMP yet.

ipiops.ppc_send_ipi -> ppc_send_ipi

New ppcoea-MI IPI infrastructure.  This is similar to the PIC
infrastructure, but simplified greatly.

Also, convert macppc (the only port currently using IPI's) over to this new
infrastructure.  Still some minor work left to do here.

Generic soft interrupts are mandatory.

Convert macppc to powerpc bus_space.  Lots of work here from Matt Thomas,
as well as the common ofwoea code from myself.  Compile tested only,
still probably needs some fine tuning.

Also in this commit:
Convert macppc to new shared ofwoea routines.
Lots of KNF.

HAVE_GENERIC_SOFTINTRS is no longer optional.  Delete ifndef'd code from
oea_machdep.c, and move softintr__init() to oea_startup().  Remove
softintr__init from every port's cpu_startup().

More cleanup:
1) Remove lcsplx, strayintr, and foosoft from all the converted ports.
None of this stuff is needed anymore.
2) because lcsplx is just "return spllower", just call spllower from
locore_subr.S instead.
3) Every port (except macppc) had a pretty similar cpu_configure(), so
take the common parts out and make a genppc_cpu_configure() in an attempt
to stop using imask[] outside of intr.c

by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their

The comparison of the .o files was based on the output of "objdump -D".

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.

Enter ddb after ddb_init() if -d is specified.

Rearrange console selection code.
Now usb keyboard is preferred to adb.

Pullup 1.82 [tsubai, mycroft]:
Enable console in initppc().

Fix a bug introduced in BOOT_FLAG change.

add new macro BOOT_FLAG() (defined in <sys/boot_flag.h>) - this
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate

as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro

for hpcmips, use new bootverbose instead of it's own hpcmips_verbose

Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.

Add an align argument to uvm_map() and some callers of that
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.

First attempt to spin up the secondary processor on 180MP and 200MP.
XXX Need more work.

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.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

Add all RAM regions to battable.

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.

Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

Update several ports to at least work again without IPKDB

Sorry for breaking this with my last changes :-(.
Fixes PR#9671 by Lennart Augustsson.

Correct the number of arguments to wsdisplay_set_cons_kbd(), for the

Deal with /psuedo-hid in the following atrocious way:

Consider "have /psuedo-hid and only ADB keyboard" case to make the
new PowerBook G3 happy.

Change the vm_map's "entries_pageable" member to a r/o flags member, which
has PAGEABLE and INTRSAFE flags.  PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that.  INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now).  This will eventually
change now these maps are locked, as well.

* convert to using MI allocsys(). most ports were using an MD allocsys(),
  although a couple still used the old pre-4.4-lite (?) mechanism.
* use format_bytes() to format the various printf()s that print out memory sizes

Rewrite the USB keyboard console attachment (again).  Grumble, Macintosh
firmware sets the "stdin" property of /chosen to be a pseudo-hid (yes, they
even spell it incorrectly) that merges all keyboard input into one stream,
so we can't find the USB controller we're attached to.  Instead, just give
it to the first USB keyboard found during autoconfiguration.  So that we
have SOMETHING available early on, use OpenFirmware i/o to do keyboard
input to the console wsdisplay until the USB code attaches the keyboard.

From Jason Thorpe <thorpej@nas.nasa.gov>

pullup 1.43->1.44 (thorpej)

For whatever reason, we just can't call pci_init() that early on Bandit
systems.  Why?  Who knows.  Firmware bugs, maybe.  In any case, moving
the call out of the ADB path works.  "Good enough for me."

pullup 1.42->1.43 (thorpej)

Completely rewrite how cninit() determines which keyboard to use with
the console.  New algorithm:

* if stdin == keyboard, and parent of keyboard == adb, use ADB.
* else, must be a USB keyboard.  Search backwards though the parents
until the USB controller is located.  Determine its location in the PCI
domain, and which type of controller it is, and tell that controller that
it has the console input device.  The USB code will then attach the first
USB keyboard as the console input device during autoconfiguration.

The iMac and Blue and White G3 consoles are fully functional now!

Now we can use symbols in DDB. :-)

Modify syncicache on PowerPC from an inline to a real function.
Support different cache line sizes with the same object code in userland.
While here, move the function to implementation name space.

Now that we have direct-mapped pool pages, we can garbage-collect VM_MBUF_SIZE

Don't call configure() from cpu_startup().

Changes for modified pmap_enter() API:
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.
