- Use PCI_INTERRUPT_PIN_MAX and I386_PCI_INTERRUPT_LINE_NO_CONNECTION
instead of magic number.
the Following changes are
{Modified with,Approved by} UCHIYAMA Yasushi <uch@netbsd.org>:
- Do not touch a PIRQ router, if the PIRQ is already routed
by the BIOS, or no appropriate IRQ is found for the PIRQ.
The latter prevents a panic on the machine of Frank van der Linden.
- Do not modify a PCI Interrupt Configuration register,
if it is already set by the BIOS, even if it is inconsistent
with the PCI IRQ routing table provided by the BIOS.
(The PCI Interrupt Configuration register seems to be more reliable
than the PCI IRQ routing table.)
This is needed to prevent a incorrect header_fixup() caused
by the incorrect PIR table on a Panasonic Let's Note AL-N2T516J5.
Provide "options PCIBIOS_INTR_FIXUP_FORCE" to retain
previous behavior, i.e. believe the PCI IRQ routing table
and ignore the PCI Interrupt Configuration register.
Although I'm not sure this is really needed.
- Do not modify a PCI Interrupt Configuration register,
if appropriate IRQ is not found for the link.
- Move a pciintr_icu_getclink() call and a pciintr_icu_get_intr()
call from pciintr_link_fixup() to pciintr_link_alloc(),
and only allocate pciintr_link_map if those calls succeeded.
This reduces number of calls of pciintr_icu_getclink(),
and also avoid necessity to validate a clink value in
ICU's {get,set}_{intr,trigger}() functions.
The sanity checks are not removed yet, though.
- Fix uninitialized usage of variable `bitmap' on stage 3
of pciintr_link_fixup().
- Remove a member variable `old_irq' from struct pciintr_link_map.
- Always use 0x%02x for printf format of canonical link value.
- Use DIAGNOSTIC instead of PCIINTR_DEBUG for really weird situation.

- add several debug printf which can be enabled by FIRESTARDEBUG.

This keeps the SR management more contained in locore, and should
be roughly the same performance as the .text size is less. Talked
to simonb and he was ok with this change.
jhawk. This callback is used by platform code to manage things like
watchdogs that should be disabled while in ddb. Done as a callback
for processors such as mips that support lots of different systems.
Add ddb support for QED opcodes, fill in enough routines so "next" usually
works, kdbpoke support for any size. Add callback that ports can hook when
entering and leaving ddb. This can be used for things like turning
off watchdogs while in ddb.
different than on the DECstation).
- Use IOASIC_DMA_BLOCKSIZE instead of PAGE_SIZE.
Should make this work on the Alpha. From discussion with
Izumi Tsutsui, Gregory McGarry, and Chris Demetriou, and
much reading of EK-D3SYS-PM.
bootblock revision strings, use bootbock_name[] (i.e. "NetBSD/sun3")
in initial bootblock messages instead of just "NetBSD"
while here, do sligh Makefile cleanup to share more code between them and also
to make buildable on NetBSD 1.4.1 (my test compile system)
get rid of the XX define hack for netboot & ufsboot, build xxboot.c as
part of libsa - previos main() was renamed to xxboot_main(), main()
is now in respective conf.c files and calls xxboot_main() with
appropriate name of boot block type
XXX I had no chance to actually test the resulting bootblocks, but the
changes were fairly streightforward and should no influence functionality of
boot code
