hi,
i'have this machine (sgi indigo2/impact R10K, the purple one, equipped with a Solid Impact gfx)

Code:

>>hinv
                   System: IP28
                Processor: 175 Mhz R10000, with FPU
     Primary I-cache size: 32 Kbytes
     Primary D-cache size: 32 Kbytes
     Secondary cache size: 1024 Kbytes
              Memory size: 320 Mbytes
                 Graphics: Solid Impact
                SCSI Disk: scsi(0)disk(2)
               SCSI CDROM: scsi(0)cdrom(4)
                    Audio: Iris Audio Processor: version A2 revision 1.1.0



i installed gentoo 2006.1 to an impact R10K, and i set the PROM-evironment this way
Code:

>>printenv
OSLoadPartition=scsi(0)disk(2)rdisk(0)partition(8)
SystemPartition=scsi(0)disk(2)rdisk(0)partition(8)
OSLoadFilename=ip28(gentoo)
OSLoader=sash64
AutoLoad=No
TimeZone=PST8PDT
console=g
diskless=0
dbaud=9600
volume=80
sgilogo=y
autopower=y
netaddr=192.168.0.5
eaddr=08:00:69:0a:3a:9a
boottune=1
cpufreq=174
ConsoleOut=serial(0)
ConsoleIn=serial(0)




i configure the last-one 2.6.17.ip28 kernel in these two ways:

(A) without support for EISA-bus and for sgi-framebuffer
(B) with support for EISA-bus, for virtual terminals, for sgi-framebuffer


now, (A) boots very well, while (B) start booting, then loops for ever

see the following:

(A) boots very well

the same happens using the prebuild kernel from http://dev.gentoo.org/~redhatter/mips/sgi/ip28/kernel-images/
i think the problem is related to the gfx solid impact: removing it in (B) cause the system to complete the boot process, keeping the gfx inside EISA bus in (B) cause the system not to complete the boot process: it seems stalled waiting xever for something from the hardware.


do you have any idea of the problem ?

That is unusual. You mention graphics in the EISA bus -- Last I checked, Solid Impact boards plugged into the GIO64 bus ports, not EISA. ;-)

That kernel I built definately does have VT and IMPACT support inbuilt. That said, I'll put up another image in a moment. What does your arc.cf look like?

That should be fine. So the problem is it loops when using IMPACT console, but not when using serial?

the problem is the that with the gfx-framebuffer enabled in the kernel the machine loops 4 ever.
It loops if the console is UART, it loops if the console is gfx. It always loops for ever causing me to reset and to boot a kernel without the framebuffer support.

I have noted that your indigo2 is a green one, i'm speaking about the purple one, i think it is different in the solid impact, because your kernel loops too, while you say you have booted it with success.

May be we are speaking about 2 different machines: indigo2 green and indigo 2 purple, both are R10K, or i don't know how to explain the difference ...

Actually, the teal case is merely cosmetic. It's still an IP28 stuffed in that case. Most R10k Indigo2's are the purple colour you describe though.

Just a question... when you boot from Impact console, is the PROM set up to use Impact or serial console?

The Impact driver in Linux relies on the PROM initialising the graphic board.

i've done these 2 tests:

A) setenv console g, boot kernel with impact fgx framebuffer, PS/2 mouse & keyboard plugged
B) setenv console d, boot kernel with impact fgx framebuffer, PS/2 mouse & keyboard plugged

in case A and B the kernel halts its booting and loop for evere. I've noticed the monitor has a flashing in case A, nothing happens in case B: blank screen.

Irix boots very well and i can see it on the screen. What could be wrong ?

again, removing the gfx video board form the GIO64bus causes the system to boot fine.

i report gfx solidimpact's chips label:
chip1: SGI/ISD 1994 Vi01 REVA 099-9028-011 83G61HF0008

I can only think that there's something funny with your framebuffer board that Linux does not like.

What do you mean by "monitor has a flashing"? I've seen some monitors that go into standby mode (flashing their POWER LED) when they detect no signal, or can't sync. Does the monitor have any On-Screen Display menu, and if so, can it tell you the sync-rate of the video signal?

it is what happens: i poweron, i see the prom menu, i enter the command menu, i boot gentoo, suddenly the monitor detects no signal, and the system is halted.

The nosync could be a problem of the monitor, but the boot is halted: i mean no serial console, no ssh console, no sound from the harddisk, nothing: the boot is really halted in a loop.

Here, i have 3 solidimpact boards, they are working with IRIX, they are not with gentoo.

Personally i think your SolidImpact board is different from mine, we can explain the monitor flashing (it should be a problem in video sync, Irix works, gentoo doesn't), but if i use your kernel, there is no explanation about what i see on my system: a boot completly halted: i really think is a driver problem.


when i plugged a 3com eisa board on an other indigo2 i experienced slots are not the same: irix had problems if i put this 3com board in the "wrong slot number": EISAslot1 is not the same as EISAslot2, ecc. It seems silly, but slots are numbered and i have experienced this stupid problem. So, which slot have you plugged with the gfx video board ? (yes, i know, i have experienced an EISA slot number, the gfx is GIO64, but ... just to know if this is the silly problem)


Anybody else has experienced this problem, here ?
i'd like to hear from other gentoo-forum-people, expecially from who owns a purple indigo2 impact.

my impact is well running, now i'd like to plug an IDE-HD controller in the EISA slot

has anybody expirienced this idea ?

could you suggest me a good IDE-hard-disk-controller-board to plug in the impact-EISA-slot ?

i mean a board supported by the linux IDE/ATA drivers

thank you

EISA support on IP28 is practically untested. With a few patches (the URLs to which I have misplaced) you can get it to compile. My understanding is that things like DMA don't work properly (sound cards are non-functional for instance) and thus you'd have pathetically slow disk I/O throughput.

octane2 (on-board) sound card is working :D
indigo2 (on-board) sound card is NOT working :(


i think i will build (or buy, i see it on ebay-shop @ $100+shipping) an adaptor SCSI<-->ATA
[may it be a good electronic project for my university degree ? scsi are too expensive !!!]

Yep... I'm aware of the problems regarding HAL2 on IP28. Incidentally, it's the same result I face on the O2... if they don't crash the machine, they cause severe distortion when playing a waveform.

yes, HAL2-IP28 is terrible ! no sound from it, no love, only noise.

so personally i think i'd better plan to add an I2C-mp3-audio-decodert-chip (<$40) on the IP28-LPT and to buld I2C kernel support
Then i will cat song.mp3 to "/dev/i2c" and the chip will decode stream into audio ;)

gosh, so should have realized a 300Gb-ip28-200Watt-mega-iPOD ?
yes, an alternative use of an obsolete machine: LOL !!!


[silly, mad, but LOL, isn't it ? ;) ]

Hardly worth it, when the host CPU can do it just fine. ;-) Parallel ports don't have much bandwidth.

On the SCSI->ATA thing... it might work... I've never tried.

i'd like to put a 8250-16550 uart chip board on the EISA bus

here i have got a lot of 16450 8bit PC board, i plugged one of them inside the indigo2, i enabled /device-drivers/character-devices/serial-drivers/8250-16550
/bus-optiones/EISA-support

i reboot, the kernel is instable, the indigo2 serial line stops to work, i can't see nothing on the serial console

i used ssh and i reset to
/device-drivers/character-devices/serial-drivers/IP22-zilog-8530-serial-port

the uart card should work on the EISA bus. It is not working.

i wander if we'd better rewrite EISA-driver in polling way :P
i realize IRQ and DMA are reasons to failure

at last, it is well working =P

here I've got this CGA CRT http://www.webalice.it/devilcoder/myphoto/mystudio.jpg (the one on the left, the orange one)

that comes with a wonderful ISA graphic card (it is very hard to find CGA now a day, but i've found it =P)
I'd like to add it into my impact as THE text console =P

I think it is a bit hard to write/adapt the driver in the linux sources =P

Little wonder really... CGA cards rely mostly on BIOS routines, or by hooking a specific region of memory, which is directly written to by the OS/applications.

This is why you can't have multiple CGA cards in a machine for instance ... they both try to hook the same BIOS routines, and the same regions of memory.

Now the BIOS is non-existant on a SGI workstation. They have a PROM which pay sweet FA attention to the EISA bus -- that's the operating system's worry -- the PROM is only concerned with the onboard hardware. The memory region used by the CGA adaptor will probably clash with something too -- they were not designed to talk to SGI computers, or vice versa.

Likewise with the serial board -- they were designed with IBM-compatible hardware in mind, which SGI computers are anything but.

ok, so i'd better build my own CGA adaptor using an CCPLD soldered to an ISA prototype board: in this case this board will be seen by kernel as a normal "memory mapped device" in where the kernel linux has only to move data. What the kernel moves to it will be putted to the video ram so ... displayed on the CRT at last. Easy.


pro:
1) no bion requited
2) handling the graphic board means handling an easy memory mapped device
3) you can allocate the smartest address to the device, so the SGI mon should be happy
4) no DMA, so no futile complicated add on: we are talking about a slow text only console
5) no interrupt design

=P

could you suggest me good memory addresses in where i coudl map my own developed device for the indigo2 isa bus ?

is there any documentation about it ?

No idea... you're asking highly technical questions about the hardware implementation of the IP28 that are so far over my head it isn't funny.

We support running Linux on the IP28.

We don't support hardware hacking of the IP28.
