reliably supporting badaddr(). False negatives appear to occur
approximately 1.8 percent of the time, although neither false positives
nor consecutive false negatives occur. We take advantage of the latter
property and always use a wrapper that makes multiple checks.
My IP12 no longer sees occasional ghost devices and related panics during
boot.
Devices present on the GIO bus needn't always provide a Product
Indentification Word, even if their address space is the same as the
address space of a slot. Separate the handling of probing for slot-based
devices and graphics devices, matching the latter first, and precluding
addresses probed for the former when a graphics device is known to exist
in a slot's space.
for. Also, remove the 'clk_freq' variable, since this value differs on a
per-platform (IP12 is 20MHz, others are 10MHz) basis.
NB: I have no idea what frequency the GIO SCSI cards use. We'll have to
re-investigate this if we ever come across one.
results in unbootable ecoff kernels ("malloc_type_attach: bad magic"
panic). Maybe this could be fixed with appropriate flags, but elf2ecoff
produces working ecoff kernels and ecoff bootloaders, which was the reason
for the switch in the first place.
GIO slots. This differs from Indy, which has an interrupt per slot, neither
of which is the same as on the other two machines.
This lets my Phobos G160 run in both slots in my Indigo2 and my E++ adapter
works in both slots in my Indigo.
connected to the HPC. The only real reason for doing this is to get the
mac addresses off of E++ ethernet boards and the Challenge S IOPLUS board.
If no eeprom is present, we read in invalid data and take some default
action (query ARCBIOS).
based on mach_type (or at least know the major revision). The only case we
really need to concern ourselves with is differentiating between HPC1
and HPC3 on IP22. Specifically, between a HPC3 on the Challenge S IOPLUS
board and a HPC1.5-based adapter in an Indy.
- 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.
version.
Add disk_blocksize(9) so that disk drivers can record the physical
block size of a disk if it is different to DEV_BSIZE. Right now this
simply initialises dk_blkshift and dk_byteshift according to the
supplied block size. This information is used in the MI version of
bounds_check_with_label().
from cpu_configure(9) to cpu_initclocks(9) on mips ports which use
mips3_clockintr.c:mips3_clockintr() (i.e. CPU INT5 clock) to avoid
hardclock(9) before softclock interrupt is initialized in initclocks().
This should be harmless because initclocks() is a part of configure()
in these days and there is no MI function which expects hardware
interrupts between cpu_configure(9) and cpu_initclocks(9).
Disccussed on tech-kern and port-mips.
