firmware likes to put PCI memory resources into this range, notably a Rage
IIc which puts the 2nd register aperture to 0x2000.
This should allow a few graphics chips to work with XFree86 which previously
failed with something like this:
(WW) ATI: PCI/AGP Mach64 in slot 2:5:0 could not be detected!
No devices to configure. Configuration failed.
Thanks to Florian Stoehr for doing most of the work tracking this down.
- fix a panic in mach64_alloc_screen()
- some cleanup
- restrict mach64_mmap() to addresses which belong to it
- mach64_attach now prints bus addresses instead of kernel vm addresses
- initial support for macppc
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
move a few bits around and make adding screens after attach time
actually work.
When not booting as console, try to properly set up the hardware to
get a display nevertheless (XXX - does not yet work on my U5).
#if 0 some unused functions planned for future extensions (to make clear
they are unused now)
offset calculation. Mostly from Bang Jun Young.
Don't call wsdisplay_cnattach unconditionally.
On sparc use OF to decide whether we are console output.
This makes it actually work on my U5 - if only we had a keyboard driver
to produce wskbd events (coming soon).
