efika powerpc

Looking at the syslog the data actualy seems to come from the bios!!, but i think it is not.

Having the card put in my old PentiumII pc i can use rovclock and write new settings for memory speed. But when i put back in the efika it is back at 40mhz. Also when in the PentiumII pc and after setting new memory speed and then trying to run glxgears the pc freezes after a few frames.

Reading out the memory speed at my pc returns 330mhz, i think that is way to high, so rovclock seems not to be working correctly. Radeonfb does not report anything in the syslog on pc.

Also running ppracer (tuxracer) on my pc gives me about 12 fps. But then its xorg.conf is not optimized.

Next try is getting windows back on the pII. And see if i can write a proper memory speed from there. And also give tux racer a try there.

Rovclock can change the clock speeds of a running card. As soon as you shut down or reset, the effect of Rovclock is lost. As soon as you start your computer, the BIOS initializes the default clock speed. This default clock speed can be changed by a Radeon BIOS programmer. Such a programmer can modify a BIOS image which you can flash into the card.

What makes you think Radeonfb reads the clock speed from the BIOS? Is radeonfb active on your desktop PC at all? If yes, it should print clock rates.

Yes in the syslog i find a line about reading from the bios
and the radeonfb puts out a line with details about clock and memoryspeed. I should lookup my password for the pgd forum so i can copy and paste from the syslog.

I do think radeonfb is up and running as whilst booting i see a tux at the top of the screen, below is text.

So a radeon bios programmer is what i need, does such a program exist?

Radedit is a good BIOS editor:

You'll have to use Windows though.

I cannot make a backup from the bios under windows, the option is disabled under ati tool.

Also here is an partial dump from the syslog

Having had the card in windows seems to have had a good effect on the memory settings as it now is 240mhz!!! No further effect though, lets try ppracer once more.

**dmantione** · 01-03-2007, 09:04 PM

240 MHz?! That is pretty normal. You wrote 40 MHz above...

Ok, we're at a dead end then, 240 MHz is enough to get reasonable frame rates.

**noeska** · 01-03-2007, 10:11 PM

I am sure it said 40mhz before. No difference in speed though. So memory is not to blame.

Looking at /var/log/xorg.0.log i see:

I hope these are non important.

Also i noticed that the memory usage of the efika is of direct influence on 3d speed, at least for tux-racer.
