Both patches don't fix anything over here. They do pretty much as if nothing

After fixing the patch (it was not applying correctly on the previous three
patches 77705, 77706 and 77743) and recompiling, it seems to fix the error.

Even with gfxpayload=text (which is working correctly without all the patches),
I still have the AMD-Vi IO PAGE FAULT messages.

Maybe, I'll test it later then. After all, I do have gfxmode and gxpayload used
in my grub.cfg.

I have gfxmode/gfxpayload commented out from grub.cfg, maybe that's the

Well, it does help: the screen switches from GRUB to kernel correctly set
(displaying the console), then the screen flashes for a moment (one white flash
instead of one blue flash when the reported bug happens), comes back to normal
in console (where there is now the AMD-Vi IO PAGE FAULT messages) and continues
to work even after Xorg is started.

A difference between Vladimir and I is we don't have the same video card (6950
over here).

Vladimir, do you see a page fault in your dmesg after applying the four
patches? Something that would look like:

Possibly.  I'm hoping to get hear back from the hw guys early next week to see
if I can get teh existing code to work as it's supposed to.  If not, I'll just
send these patches upstream for now.  If they don't make 3.9 final, they'll
show up via the stable kernel stream.

[Bug 57567] 3.7 radeonfb broken on efivga screens

  Alex, is this expected for the workaround?
 
 No.  So it appears turning off the displays doesn't help either :/

Well, it does help: the screen switches from GRUB to kernel correctly set
(displaying the console), then the screen flashes for a moment (one white flash
instead of one blue flash when the reported bug happens), comes back to normal
in console (where there is now the AMD-Vi IO PAGE FAULT messages) and continues
to work even after Xorg is started.

A difference between Vladimir and I is we don't have the same video card (6950
over here).

Just tested with 6970, still fine, no AMD-Vi messages in dmesg.

I have gfxmode/gfxpayload commented out from grub.cfg, maybe that's the
difference between your and mine setups.

Maybe, I'll test it later then. After all, I do have gfxmode and gxpayload used
in my grub.cfg.

Even with gfxpayload=text (which is working correctly without all the patches),
I still have the AMD-Vi IO PAGE FAULT messages.

I was able to log in, launch "xset dpms force off". My screen turned off. After
waking it up, the display was still shifted.

X starts, but I'm never getting to the log screen. Once X is started, if I go
into console and come back, only my mouse pointer is being displayed correctly,
the background stays as what was in the console. I suppose something is hanging
or crashing X.

I think you can adjust the console blanking with setterm.  Can you start X and
force a dpms cycle even if the screen is garbled?

On the console, just wait for the screen to blank.  In X:
xset dpms force off
will force a dpms cycle.

Using a Cayman 6950 with both patches didn't help over here. Tried two times,
two times where the screen was shifted (like in Vladimir's screenshot). First
time flickering, second only shifted.

[Bug 57567] 3.7 radeonfb broken on efivga screens

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=57567

--- Comment #31 from Alexandre Demers alexandre.f.dem...@gmail.com ---
(In reply to comment #30)
 Created attachment 77706 [details] [review]
 additional fix
 
 Apply this along with attachment 77705 [details] [review].

Using a Cayman 6950 with both patches didn't help over here. Tried two times,
two times where the screen was shifted (like in Vladimir's screenshot). First
time flickering, second only shifted.

New screenshot

It actually became worse, hard to replicate scenario with shifted screen(most
of time looks like 3.8), and then it panics on reboot. Sshot of panic attached.

Ah, and without patch it is always same as with 3.8.

I have strange results

few notes first, 3.8-ati is 3.8.5 kernel + reverted
62444b7462a2b98bc78d68736c03a7c4e66ba7e2

3.9-rc5_patched is  3.9-rc5 with your latest patch

3.8 - ubuntu vanilla 3.8.5

so, here is all results:

1) cold boot, boot 3.9-rc5_patched - same screen as with 3.8 (bad)
2) boot macosx, reboot, boot 3.9-rc5_patched - same screen as with 3.8
3) boot 3.8-ati, reboot, boot 3.9-rc5_patched - result like on previous
screenshot I've posted, horizontal shift is always different 

I didnt test 3.9 with your first patch with all cases.

I don't have a picture as neat as yours. I also saw a change in the display,
but my display is flickering after the first few vertical lines (only the first
few lines are stable, but they are still shifted as in your screenshot).

I've just tested vanilla 3.9-rc5, to be sure that it's actually your patch that
make things a little bit better, not 3.9 kernel itself.

unpatched 3.9-rc5 - same ersult as 3.7/3.8 kernel, so yeah, it's definetly a
patch.

new dmesg with drm.debug=14

It's a little bit better now, framebuffer is always shifted. (previously
framebuffer usualy was lost, or messed up). it's 3.9-rc5 + patch

I've also tried 3.8.5+patch, and saw no difference to just 3.8.5, just saying.
