[parisc-linux] PALinux on HP9000/735-125

[parisc-linux] PALinux on HP9000/735-125

[Sven Cronenberg]

I installed PALinux 0.93 on my HP9000/735 running hat 125Mhz. I use
a SCSI Disk connected to the narrow SCSI canel and the CRX48z
graphics system.

Im using kernel version 2.14.16-pa24 and updated the debian packages like
mentioned in the 0.9.3. errata section today.

Some questions:
- I tried execessing the framebufferdevice. 'fbset' report '/dev/fb0: no 
such device'
  though the STI console works fine as a text-console. Whats the reasion 
for that error?
  Can I currently use the framebuffer device on the HP9000/735?
- has someone been able to make the 100mbit EISA-ethernet-card 3c597 work
  in the HP9000/735 under Linux?
- can I enable a german keymap for the HIL keyboard (trying to do this 
during the
  installation made the keyboard totaly unusable so I had to reboot )?
- is the HIL mouse still unsupported or is there a patch or so to make 
it work?


But inspite of all these problems:
Nice work. It's great to see my PARISC Box running a free operating 
system instead
the obsolute HPUX 10.20.

Try a newer kernel. It might work starting with kernel 2.4.17-pa2 and above.

Sorry, no idea.

You might want to write a script with setkeycodes.
Search the archives, I think I once sent such a script.

Still unsupported.

[parisc-linux] Use the X-Server from HPUX und PALinux?

[Sven Cronbenberg]

On many PARISC Systems there is still no X-Windows
support or X-Windows has to access the graphics card
via the framebuffer device.

I wonder if there could be a chance to get the X-Server
from HPUX working under PALinux. Would the HPUX
compatiblity be good enough to have a chance whith
that?

Perhaps the suggestion sounds a bit unconventional but
for example many people running NETBSD on the
680x0 based HP-Workstations have made good experiences
with that. For example I am running a HP9000/425
und NETBSD 1.5 but because the HP300 port of
XFree is slow and buggy, I use the Xserver from
HPUX 9.

Well, originally that was the plan John Marvin had but I don't think
he's had time to work on the missing kernel support (ioctl calls for
gfx card drivers). If someone wants to try it and report what's missing,
we might find time to get it working peice meal.  In general, HPUX 32-bit
SOM binary support is in place though no one is regularly testing it.

You are aware of the STI framebuffer driver right? You can use that to run X 
on most HP graphics cards. The HPUX Xserver could be much faster but sti-fb is 
currently better than nothing.

crx48z is untested, so we don't try to use it in framebuffer mode. There
is a check in drivers/video/stifb.c which refuses untested cards (search
for Hack). Just remove that check and see what happens.

if you build your own kernel with the check removed, it might work.

IMHO no EISA card will work at the moment. During the weekend I tried
to get an Adapatec 1742 card going in my B132, and the problem is,
that the pdc doesn't initialize EISA cards. Looks like that is done
by HPUX. So before any EISA cards will work, we need something like 
that for Linux, too.

I was trying to get EISA cards working a while ago. The basic problem is,
as Thomas indicated, that the EISA cards need to be configured by a
configuration utility before you can use them. HPUX has a utility called
eisa_config, but there is no equivalent in Linux. Seems all other EISA
platforms (i386, alpha, mips) can be configured by booting a diskette, so
nobody bothered with a linux version yet. 

I think it should work to boot HPUX, get the correct EISA .cfg file and
use the eisa_config utility. The configuration is actually stored in an
eeprom, so it's not tied to the OS. I can't test this though as the only
HPUX CDs I have are too old for the machine.

Another option may be to run the utility on Linux, tried that once but it
complained it could not access /dev/eeprom. A bit scary too, if something
goes wrong one could end up with a corrupt eeprom....

but that's not enough. I did that and setup the card with HPUX, but it's
still unconfigured, when Linux finds it. The .cfg describes how to
configure the different card parameters, eisa_config puts the selected
params to a nvram, and some other part does the real card poking
during kernel startup. Other platforms have that card poking stuff
included into the firmware.

It isn't a big deal to do the card setup itself, because .cfg includes
everything needed. It's more a problem of getting that information
during the kernel startup. If we know the nvram setup and how stuff
gets put there, we could read that and do the card setup from within
the Linux kernel. But I haven't found anything about that, yet.

Just as a mostly offtopic note you may well be able to get some help with
this (or loan out some help) to the mips port.  Some SGI systems (SGI I2
comes to mind) have EISA slots, and I suspect suffer from the same
problem, it's also possible that SGI has come up with a workaround for it,
so you'd have to get in touch with someone in the know.

I think that the PDC only initialize a card that is used for booting. I also
think that Matthew Wilcox had a HP 100MB Ethernet interface up and running a 
while ago. (The PDC might have initialzed that board when it searched for boot
devices.)
Another problem with EISA boards currently, is that most of them are bus-masters
and the current EISA support lacks the busmatering and DMA bits.

I have started an eeprom driver a while ago, and I started to try to decode the 
EISA parts of the EEPROM. I have about half of it figured out I think, but the
other half seems to be somewhat hard.

I looked a doing a parser for the CFG files, but it turns out that there are a
lot of options and stuff. Even binary code overlays that are supposed to be
loaded and executed by the ECU (EISA configuration utility) exists. Adaptec 
uses one for the AHA-274x. Not suppoered by HPUX, though.

hmm, I had a quick glance over the hp100.c and it looks like the driver
does the eisa config itself. So that would explain why it worked.

that's why I was looking into the problem. I wanted to improve EISA support.

that's a start. Do you have a patch for your eeprom driver somewhere ?

I saw that overlay thing also for the AHA-1742. I just removed it from the
.cfg to get eisa_config running with it.
