Can't boot SGI O2

[KIYOHARA Takashi]

Hi!


My SGI O2 can't boot. It hangs up in pmap.c:pmap_bootstrap().

arch/mips/mips/locore.S
arch/sgimips/sgimips/mach_init()
arch/mips/mips/pmap_bootstrap()
kern/vfs_bio.c:buf_memcalc()
if (bufpages != 0) {
:
} else {
:
mapsz = vm_map_max(buf_map) - vm_map_min(buf_map);
}
kern/init_main.c:main()
:
kern/vfs_bio.c:bufinit()
if (bufmem_valimit != 0) {
:
buf_map = uvm_km_suballoc(...)
:
} else
buf_map = kernel_map;


And valiable 'bufpages' is maybe 0 on all mips ports.

#ifndef BUFPAGES
# define BUFPAGES
#endif

u_int bufpages = BUFPAGES;


How we avoid this problem?

Thanks,

Also can't boot alpha machine.

arch/alpha/alpha/machdep.c:alpha_init()
arch/alpha/alpha/pmap.c:pmap_bootstrap()
kern/vfs_bio.c:buf_memcalc()

Hi,

The attached patch makes my PWS500au alpha boot again by restoring the
case where buf_map is not yet mapped when called early from
pmap_bootstrap().

Excellent!
My AlphaStation 500/333 works fine.

However I can't test on sgimips. My sgimips(O2) died... X-<
Maybe power suply.

Please commit your patch. :-)

Hello.

Oracle/Sun/Cobalt's FTP site no longer has the Qube2 ISO image of the restore
CD. Does anyone have the image somewhere that I could download it from? Thanks.
