             Bug #: 43655
           Summary: Latest radeon dri driver on HD6950 with kernel 3.2
                    flickers
    Classification: Unclassified
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: alexandre.f.demers@gmail.com


My new HD6950 flickers like hell right from the initialization. Using kernel
3.1.0 is just fine, but kernels 3.2.0-rc3 and over make the screen flicker (I
can't tell for versions in between for now). Also, the screen seems shifted by
a bit more than half my monitor's width.

I also have an integrated HD3200 and I have no problem at all when selecting
this integrated chipset over my PCI-E 6950 with the same driver and kernel
combinations.

Can you bisect?  Did you update any other components (mesa, xf86-video-ati) or
just the kernel?

More info about this bug: I have both kernel 3.1.0 and 3.2.0-rc4 installed
right now (compiled from kernel.org). I had 3.2.0-rc3 installed, before moving
to rc4 to test if the bug had been solved.

Have I updated other components? Of course, I'm testing with latest versions of
both mesa and xf86-video-ati (I'll have to test today's versions though). But
then, it shouldn't be a problem since I'm testing the same components with both
kernels.

I'll bisect kernel's commits in the next couple of days to find which one is
breaking things.

OK, so after testing first all RCs, I narrowed the problem between RC3 and RC4.
So, bisecting gave me the following culprit:

commit 9b5a4d4f65e260a109eaeea8bbc8062a7c58b55e
Merge: cb35999 67589c7
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Mon Nov 28 13:49:43 2011 -0800

    Merge branch 'for-3.2-fixes' of
git://git.kernel.org/pub/scm/linux/kernel/gi

    * 'for-3.2-fixes' of
git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu
      percpu: explain why per_cpu_ptr_to_phys() is more complicated than
necessa
      percpu: fix chunk range calculation
      percpu: rename pcpu_mem_alloc to pcpu_mem_zalloc

It has nothing to do with drm in itself. But it must be related at some
point... I'll reset my tree tomorrow and retest to be sure by compiling just
before this commit.

Strangely, when rebisecting, I found commit
a34815b96f9a21b3a2e2912dfd0d994acd2855e3 to be the bad one... It is really near
to the first one. So, I'm retesting both to be sure.

It sounds like the problem may happen or not with a certain probability with
any given kernel. You should probably test each kernel a certain number of
times before declaring it as good, or the bisection may not work correctly.

I tested today's latest kernel version after fighting with the beast for the
last couple of days. Just to be sure, I made a clean compilation and it now
works properly without any problem. I'll assume for the moment it was related
to something stuck in the compilation.

If anything goes wrong again, I'll reopen the bug.

This is one driving me crazy. You were right, it is no reproducible everytime.
I have to reboot a couple of time to trigger it or to fix it... Going back to
bisection.

--- Comment #8 from Alexandre Demers <alexandre.f.demers@gmail.com> 2011-12-15 17:50:38 PST ---
I think I've found a hint. Here's the thing:

Whatever kernel version is the first entry in my Grub's list, the problem will
appear. If I select a different kernel manually or if I change the default menu
entry to a different one, everything is fine. The only exception is if my first
menu entry is Windows. Then, there is never any problem.

Here is what I see when selecting the first entry. First, the Grub's background
stays for a moment and then it switches to the boot screen (using Ubuntu, it
shows the Ubuntu loading screen). However, most of the time, it will flicker,
usually showing only a couple of clear lines at the top of the screen.

If I select another entry, it switches to the kernel initialization (showing
step by step what is being done) and then it switches to the boot screen only
after having initialized correctly the screen. The only difference I can see
between the first entries and the others is the following in my grub.cfg:
    set gfxpayload=$linux_gfx_mode

I suspect a bad interaction between Grub and the rest of the initialization
process. Does my suspicion make sense?

Quite possibly. Can you test your hypothesis by moving this line between
entries?

Tested and confirmed. Whenever I added "set gfxpayload=$linux_gfx_mode", there
was a really high chance of hitting this bug (near 90% of the time). Without
it, I booted flawlessly.

Should I try to bisect drm driver to see if there is a version without that
problem? I've had this new 6950 for less than 2 weeks, so I don't even know if
it worked correctly at some point.

--- Comment #13 from Alexandre Demers <alexandre.f.demers@gmail.com> 2012-07-21 03:49:15 PDT ---
It's been some time now. Since my initial report, I moved from Ubuntu to Arch.
Today, it was officially announced Arch was moving to Grub2. So I updated my
setup (I was using Grub legacy since my move to Arch). Suprise, this bug is
still valide.

So I played around with grub default options. So GRUB_GFXMODE=auto works fine,
but GRUB_GFXPAYLOAD_LINUX=keep triggers the bug. Removing the latest option
makes everything runs smoothly.

I read bug 49262 and two things are common with my setup: we are both using a
69XX radeon card and we are both using a DVI-to-VGA adaptor. I'm wondering if
the combination of card AND adaptor was the root of the problem. Before having
this 6950 card, I was using an Radeon HD 3200 IGP without any adaptor and I had
no problem.

I don't have any other monitor here and I don't have a DVI or HDMI input on my
monitor, so I can't tell yet. But still, what would you suggest to try to help
figure out what's going on? Any comment from Alex or Michel would be
appreciated. I could have access to a different monitor if I ask for it.

May well be the same as bug 42373. I'll try to find a way to dig this following
42373 repro steps.

If it's same as https://bugs.freedesktop.org/show_bug.cgi?id=42373 then patch
there should fix your issue.

It fixes it. Applied, rebooted 3 times without problem, went back to 3.6-rc1
(no patch) problem appeared, went back to patched kernel and still no problem.

Fixed by attachment 64759 (proposed in bug 42373 which is similar to this bug
but is not the same since it is not fixed by the attachment)

--- Comment #20 from Alexandre Demers <alexandre.f.demers@gmail.com> ---
I'm reopening this bug for two reasons:
 -It is still happening with kernel 3.9.0-rc4 because attachment 64759 from bug
42373 seems to never have been pushed
 -It is not a duplicate of bug 42373 since attachment 64759 fixes current bug
but not 42373

It would be nice to have a revised version of attachment 64759 that applies
correctly on latest kernel, then to have it tested and pushed to kernel's git.

So I'm trying to narrow down what is going on. Kernel 3.5 + patch 64759 works
OK. I'm now testing kernel's commit 81ee8fb6b52ec69eeed37fe7943446af1dccecc5
that was supposed to supersede patch 64759 in kernel 3.6. I'll see what I get.

My feeling is we are not saving/restoring an address (VM, VRAM, TTM, whatever)
correctly somewhere along the path.

--- Comment #22 from Alex Deucher <agd5f@yahoo.com> ---
The current code should do the right thing with respect to disabling display
access to vram when we reconfigure the memory controller.  The current code
disables memory reads but leaves the display controllers enabled while we
change the MC setup.  Turning off the crtcs as the patch you mentioned does has
two problems:
1. it breaks some systems which the current method fixes
2. it defeats the purpose of GRUB_GFXPAYLOAD_LINUX=keep which is to avoid
turning off the displays for flickerless boot up.  If you turn off the crtcs
you have to re-init the entire display pipeline.
The problem seems to be that disabling the crtc memory reads seems to take
longer than expected on some systems which leads to invalid reads while the MC
is being reprogrammed.  One possible solution may be to leave the MC as
configured by the vbios and try and put the gart aperture either before or
after the location of varm in the GPU's address space.

I understand what you are explaining. Meanwhile, I'm bisecting to find out
where it was broken again since commit 81ee8fb6b52ec69eeed37fe7943446af1dccecc5
does indeed what it is supposed to do (no problem when using
GRUB_GFXPAYLOAD_LINUX=keep). So, somewhere between commit
81ee8fb6b52ec69eeed37fe7943446af1dccecc5 and 3.9.0-rcx, something went wrong.

62444b7462a2b98bc78d68736c03a7c4e66ba7e2 is the first bad commit
commit 62444b7462a2b98bc78d68736c03a7c4e66ba7e2
Author: Alex Deucher <alexander.deucher@amd.com>
Date:   Wed Aug 15 17:18:42 2012 -0400

    drm/radeon: properly handle mc_stop/mc_resume on evergreen+ (v2)

    - Stop the displays from accessing the FB
    - Block CPU access
    - Turn off MC client access

    This should fix issues some users have seen, especially
    with UEFI, when changing the MC FB location that result
    in hangs or display corruption.

    v2: fix crtc enabled check noticed by Luca Tettamanti

So in other words, your explanation Alex seems to be right. I'll be waiting if
anything has to be tested.

Still the same. 1 boot on 4 was OK, the three others were showing the same kind
of corruptions as before.
