- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
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.
- finish implementing splraiseipl (and makeiplcookie).

- 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.

While here, remove "extern" keyword from function declarations.
the only convenient way to use the returned value with numerous library
routines which have not been altered to properly use constified char *.
This was found to be necessary when I extended yamon to hold a string
describing a video mode for use with my experimental radeonfb.

the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.
To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such. I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.
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.
- Use the CPU count register for more accurate microtime (from
sbmips) and delay (based on an evbmips delay function) functions.
- Schedule the next hardclock interrupt more accurately (from
an sgimips patch by Rafal Boni). Clock drift on one board is
now ~7ppm instead of ~330ppm.
- Purge old pmax-based mcclock code.
- Correctly round off some clock-derived variable calculations.
XXX: Some of this code should be migrated to sys/arch/mips.
MIPS32 4Kc CPU board, with support for the MIPS64 5Kc and the QED RM5261
CPU boards to follow.
The cs4281 audio hasn't been tested, there are some interrupt problems
with onboard the pciide, but all other on-board peripherals work.
The evbmips port will support more MIPS evaluation boards in the future.
