Hi there,
as this is my first post, i'd like to introduce myself, although it
may be a bit off-topic ;-) My pseudonym is FAKE, i'm from germany
and proud owner of an Indigo2 R4k. I just found enough time
(thanks, santa) to fire up linux on it. My System is:
Indigo2, ~160MB RAM, GR3-XZ Gfx Board, R4400 proc.
this is my /dev/cpuinfo:
system type : SGI Indigo2
processor : 0
cpu model : R4000SC V5.0 FPU V0.0
BogoMIPS : 74.75
byteorder : big endian
wait instruction : no
microsecond timers : yes
extra interrupt vector : no
hardware watchpoint : yes
VCED exceptions : 23868
VCEI exceptions : 32852
(the PROM hinv says i have a R4400 and a FPU ... is cpuinfo right?)
Anyways, i want to contribute, and so i got the 2.5.1 kernel from
oss.sgi.com via cvs and compiled it. it boots, but exactly when the
scsi-driver is about to add the disk it oopses and i get the message
<1>Unable to handle kernel paging request at virtual address 00000000, epc ==
880db32c, ra == 880
db270
Oops in fault.c:do_page_fault, line 204:
.... ( insert useless stack trace here, becuz of non-saved system map *dough*)
sorry for not saving the System.map >_< i'll check in more deeply if i get
oopses in future.
then i compiled 2.4.14, it worked, but somehow debian didn't like it, but
that's not the kernel's
fault. Anyways, now i compiled the 2.4.16 and everything just works fine -
except devfs and the ARC
console. Devfsd says:
Error getting protocol revision Inappropriate ioctl for device
and the ARC console (one thing i especially want to get to work) behaves
strange:
As the kernel starts writing output the PROM console adds black lines to the
screen,
whilest the data from before the kernel started output (boot linux
console=ttyS0... etc)
nicely scrolls UP........ what to do? i tried to find information about the
PROM on
oss.sgi.com and toolbox.sgi.com, but both seem _DAMN_ outdated (the newest
"news" are from
2000 or something) so i'm stuck....
i would enjoy helping, but i'm still learning, as i am very new to the mips
platform...
i have some experiences with linux/the kernel in general on the intel32
platform.
well, plz reply, so i can start coding ^-^
greetz & thanx in advance
FAKE
