They are derived from 4.4BSD/sparc and have been there since initial import
of NetBSD/sparc in 1993, but the struct sbusdev is almost unused for years,
nothing calls sbusreset(), and all (*sd->sd_reset)() functions look bogus.
Suggested by mrg@ and martin@, and tested on SS1+ and SS20.
no return; need to stick in text mode as long as possible since libsa does
not include a rasops library. While here, add the 'vesa' command to pxeboot
to mirror biosboot behaviour.
backwards time was incorrect, and actually disabled the use of mfpr for
timecounters. The intent was to emulate a 32 bit counter using the
hardclock_ticks from the clock interrupt and the contents of the
Interval Counter register. The problem with that was when the ICR
wrapped, but the clock interrupt was blocked resulted in an incorrect
count. Work around this by keeping track of the previous ICR value
and hardclock_ticks to ensure the 32 bit counter doesn't go backwards.
Also, the ICR runs from -10000 to -1, so adjust the value when reading it.
Now mfpr works quit nicely on my 4000/90.
for number keys. snj@ often overshoots the spacebar in a panic and
accidentally hits 'b' instead, which makes the loader boot item '2'.
Can't fix snj@, so fix the boot loader instead.
information from the BIOS in addition to the currently selected default
partition. Handy when you don't know where to boot from. Here's a demo:
type "?" or "help" for help.

- unless otherwise specified, modules are now loaded from the same device
as the kernel ('load miniroot' now implies 'load tftp:miniroot' if the
boot command is 'boot tftp:netbsd')
- the module name -> path expansion now works when a device prefix: is
specified ('load tftp:miniroot' now works)
- if the module name has been expanded to a path, print that path when
loading the module rather than the symbolic name
- only print an error in module_open if both the expanded path and the
raw path fail to open
send pmap tlb shootdowns to them cause the shootdown job queue to fill up,
but since the cpus aren't running yet, no IPIs get sent. When the job
queue is full, the bit mask of cpus to send the IPI to is not set and no
shootdown IPI ever gets sent after the cpu is marked running. Always
set the cpumask even when the queue is full. Now I get shootdown ipis
on all the secondary cpus.
cpus are told to begin running. Since the seconedary cpus weren't being
added to the cpu_info list until then, that initialization wasn't being
done and resulted in crashes on the secondary cpus. Add the secondary
cpus to the cpu_info_list after they've been started (but waiting to be
told to start running). This fixes the problem specifically stated in
PR port-alpha/41106. MP alphas will now at least boot and begin running,
but will eventually crash in various ways later.
It will replace azalia(4) after testing.
To use, comment out azalia in your kernel configuration and uncomment the
hdaudio and hdafg lines so it reads:
# Intel High Definition Audio
hdaudio* at pci? dev ? function ?
hdafg* at hdaudiobus?
You should also:
cd /dev
sh MAKEDEV audio
address in the ISA hole (because addr+size calculations wrap to 0). Fixes
ohci on VirtualPC 7 for Mac, which places OHCI at base address 0xfffff000
size 0x1000.
The head of the list is now a pv_header, which contains the first pv_entry
as well as a 16-bit attributes field (replaces the pmap_attributes array
plus the pv_entry::pv_flags field) as a 16-bit count of caller-specified
cache-inhibited mappings.
Tested on hp300 (shared pmap_motorola.c), changes to atari and amiga copies
are purely mechanical.
