each icu irq to support multi function PCI devices in the Qube's PCI slot:
- split out interrupt stuff from machdep.c into new interrupt.c
- prepare struct *_intrhead to handle cpu and icu interrupts
- use LIST and malloc(9) to handle multiple interrupts per icu irq
(mostly taken from algor/pci/pcib.c and evbmips/malta/pci/pcib.c)
- move evcnt(9) stuff into *_intrhead from cobalt_intrhand
(i.e. make it per interrupt rather than per handler)
- in pci_intr_map(9) handle CPU interrupt separately and add a sanity check
- fixup interrupt lines for devices on the PCI slot in pci_conf_interrupt(9)
- move some device address definitions into <machine/cpu.h> and
remove <machine/leds.h>
- misc cosmetics
No objection on port-cobalt for three weeks.
- 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.

that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.
all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.
XXX: bus_dma(9) needs an update still.
- 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.
Convert to timecounters.
From Rivo Nurges (rix at estpak dot ee). ok soren@, tested by simon@.
Note that this means we aren't using the gt clock, and maybe we should clean
that up a bit.
works properly
(XXX: the real fix is to implement proper CLFK_BASEPRI())
- prepare an independent statclock(9) handler which use MIPS3 CPU internal
clock interrupt. Enabled by options ENABLE_INT5_STATCLOCK, but not enabled
by default.
- move ICU interrupt stuff from pci/pcib.h to cobalt/machdep.c
because ICU should be initialized before pcib is attached
- initialize ICU more properly
- check interrupt types and set ELCR (edge/level control registers)
accordingly in icu_intr_establish()
- check requested IRQ line and call only a necessary hander in icu_intr()
- use specific EOI to ack interrupts rather than AEOI
- use macro defined in <dev/ic/i8259reg.h>
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
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.

Patch from KIYOHARA Takashi on port-cobalt.
This change makes siop(4) (and maybe all other PCI devices
using pci mem space) work on cobalt.
to select the maximum segment size for each bus_dmamap_load (up to the maxsegsz
supplied to bus_dmamap_create). dm_maxsegsz is reset to the value supplied to
bus_dmamap_create when the dmamap is unloaded.
