Subject: Regression 2.6.34->2.6.35-rc4: radeaon KMS an RS690 broken

I just tried 2.6.35-rc4 to see, if a different bug is fixed, but noted
that this kernel will only boot with radeon.modeset=0.

If KMS is active the display turns off and the system is completely
dead, not even SysRq+B is working.

I build a new kernel with the radeon driver as a module and inserted
it by hand via ssh.
The ssh session, I was using has this output:
ariolc drm # insmod ./drm_kms_helper.ko
ariolc drm # insmod ttm/ttm.ko
ariolc drm # insmod radeon/radeon.ko
Segmentation fault
ariolc drm #

The final insmod segfaulted, the shell was displaying a new prompt,
but not new input was possible.
The system still reacted to ping and trying to create a new ssh
connection resulted in a password prompt, but after entering the
password no shell was provided.
I tried SysRq+S, SysRq+U and SysRq+B, but not visible result. After a
reboot I did not find any additional information in /var/log/messages.
The effect was like the boot time failures with a builtin radeon
driver: The display (attached to the VGA output) just turns off.

But I had a second ssh connection open, doing tail -f /var/log/messages:

KMS was working stable on 2.6.33 and seems to work on 2.6.34 (Not
really tested, because 2.6.34 is not working for me, but I'm not sure
if that is KMS related)

drm/radeon/kms: fix bandwidth calculation when sideport is present

My system does not have any sideport memory.
The other revisions before this did boot into the correct KMS mode,
but I did not test X, because I'm using that system as a remote
desktop server and only sometimes the fb text console to debug
something that went wrong.

Make sure your kernel has this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f892034a8ce80ed7098f667aae2eb6300e570603

If it's still a problem even with that patch, send me a copy of your
vbios (as root):
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/rs690.rom
echo 0 > rom

OK, thanks.

Yes. But looking at my logs the regression did not happen from
2.6.34->2.6.35 but from 2.6.33 to 2.6.34.
The first failed ring test was with the Gentoo 2.6.34 kernel, but all
the working bisect steps between 2.6.34 and 2.6.35-rc4 also failed.

I will try to bisect this tomorrow, but I'm not sure if this will
work, because 2.6.34 is not really working for me.

I bisected it to this commit:

d594e46ace22afa1621254f6f669e65430048153 is the first bad commit
commit d594e46ace22afa1621254f6f669e65430048153
Author: Jerome Glisse <[email protected]>

drm/radeon/kms: simplify memory controller setup V2

Get rid of _location and use _start/_end also simplify the
computation of vram_start|end & gtt_start|end. For R1XX-R2XX
we place VRAM at the same address of PCI aperture, those GPU
shouldn't have much memory and seems to behave better when
setup that way. For R3XX and newer we place VRAM at 0. For
R6XX-R7XX AGP we place VRAM before or after AGP aperture this
might limit to limit the VRAM size but it's very unlikely.
For IGP we don't change the VRAM placement.

Tested on (compiz,quake3,suspend/resume):
PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710
AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730
IGP:RS480(RPB*),RS690,RS780(RPB*),RS880

RPB: resume previously broken

V2 correct commit message to reflect more accurately the bug
and move VRAM placement to 0 for most of the GPU to avoid
limiting VRAM.

Jerome, Any thoughts? I got another report of the CP being broken an
an rs690 on IRC as well.
Looks like the checks that clipped vram based on the aperture size got
removed on rs600 and rs690. Also, I think ideally we want always want
mc_vram_size and the internal MC vram map to always be the actual vram
size while the part we expose to the memory manager should be clipped
to the aperture size. I think that was the root cause of the old
brightness lockup bug since there is a bios scratch area usually at
the end of vram which causes problems if we've limited the MC's vram
map.
