Add experimental support GENERIC.MP.

Remove unused enable_intr()/disable_intr().

branches: 1.31.2; 1.31.12;
Use BEBOX_REG for mapped to BAT instead of bebox_mb_reg.

intr.h must not include cpu due to deadly embrace with SOFTINT_COUNT.
Cleanup intr.h so MD definitions can overload common definitions.
Rototill pic/intr.c. Virtual IRQs can now be reclaimed. separate virq
from hwirq from picirq. Redo intr mask calculations.
tested on pmppc and macppc (MP).

branches: 1.29.6;
Support 64-bit imask for powerpc/pic.

Remove clause 3 and 4 from TNF licenses

Fix some bugs since ppcoea-renovation.
It status is reach asking boot device now.

branches: 1.26.2;
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.

branches: 1.25.6; 1.25.14; 1.25.22; 1.25.24; 1.25.26; 1.25.28;
Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts
via a soft interrupt. In the near future, softclock will be run from process
context.

merge yamt-splraiseipl branch.

- finish implementing splraiseipl (and makeiplcookie).
http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html
- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.

branches: 1.23.14; 1.23.16;
Change "inline" back to "__inline" in .h files -- C99 is still too
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

branches: 1.22.2; 1.22.4; 1.22.6;
__asm__ -> __asm
__const__ -> const
__inline__ -> inline
__volatile__ -> volatile

Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.

merge ktrace-lwp.

branches: 1.19.16;
Move CLKF_BASEPRI to machine specific <intr.h> file since it depends on
the encoding of the spl for the port.

branches: 1.18.2;
Rename IPL_IMP -> IPL_VM.

Peform a rototill over the powerpc-based ports.

Move the trap/vector initialization for MPC6xx ports to mpc6xx_machdep.c
Also move softnet, install_extintr, mapiodev, kvtop. Add common BAT
initialization code.

Add user Altivec support.

Fix calls to OF_call_method in macppc/macppc/machdep.c.

Use ci_fpuproc in cpu_info instead of separate fpuproc.

Add separate syscall.c and defined __HAVE_SYSCALL_INTERN.

branches: 1.16.4; 1.16.8;
"doesn't" should have an 's'.

achive is not a good word.

branches: 1.14.6;
Make all powerpc ports use a common Makefile.powerpc (except walnut)
Enforce -Wmissing-prototypes -Wstrict-prototypes for all ppc ports.
Split out macppc cpu support and make common to mpc6xx ports. Make
other mpc6xx ports use it. Add evcnts for mpc6xx traps.

branches: 1.13.2;
Remove the use of splimp() from the NetBSD kernel. splnet()
and only splnet() is allowed for the protection of data structures
used by network devices.

branches: 1.12.2;
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).

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

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

branches: 1.9.2;
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.

Sync w/ the i386 port. Fixes some bugs in the conventional interrupt
heirarchy. Reviewed by sakamoto@netbsd.org.

Add some declarations.

branches: 1.6.8;
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).

add The Be interrupt controller setmask function(bebox_intr_mask).
change SINT_TTY to SINT_SERIAL
splsofttty to splsoftserial, and so on.

change order of interrupt description bit

remove/import software interrupt model and external interrupt handler
from OpenBSD/powerpc.
move bus_space_* from bus_machdep.c to bus.h.

branches: 1.1.2;
Initial commit of NetBSD/bebox port.
