            Bug ID: 111122
           Summary: 2500U: Graphics corruption on kernel 5.2
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu

Kernel log

Arch Linux
Lenovo E485 (16 GiB RAM)
AMD Ryzen 2500U

xorg-server 1.20.5-2
mesa 19.1.2-1
xf86-video-amdgpu 19.0.1-1
libdrm 2.4.99-1

After upgrading to the linux kernel 5.2 from the Arch Linux repositories, my
laptop started to show graphical corruption in Firefox or Konsole. It is much
worse if something is moving on the screen e.g., a video is playing. Sometimes
Firefox is almost unusable as a result. A downgrade to 5.1.16 immediately fixes
the issues.

Somebody mentioned similar corruption for bug 109206:
https://bugs.freedesktop.org/show_bug.cgi?id=109206#c57

My kernel command line is:

initrd=\amd-ucode.img initrd=\initramfs-linux.img
root=PARTUUID=34098e4c-f1bf-4a43-a0a8-2ba3ed3c71a6 idle=nomwait
psmouse.synaptics_intertouch=1 acpi_osi=Linux amdgpu.gpu_recovery=1
ivrs_ioapic[32]=00:14.0

I used to have iommu=pt or iommu=off on the command line to get this laptop to
boot properly but I have not needed that switch for a while. I might try to
reintroduce it with 5.2 just to see what happens. In any case, my setup worked
before, so something does not seem right.

Reintroducing iommu=pt does, indeed, seem to fix these graphical issues. Why is
this flag suddenly required for proper operation again?

Is every laptop with an Raven Ridge APU different here or why can the kernel
not just figure out how to properly configure the IOMMU so that everything
works?

I think that I'm seeing something related with my 2700u Inspiron 7375.

If I have compositing enabled in XFWM4, the system will immediately stop
responding after logging in with LightDM. If the window manager compositing is
disabled, I'm able to log in, but then there is graphical corruption.

With git bisect I traced the problem back to
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=df8368be1382&id=df8368be1382b442384507a5147c89978cd60702

I can edit the source file, and by only changing the KMS_DRIVER_MINOR
definition from 32 to 30, get the system working correctly with 5.2.0.

Same symptoms here after upgrading from Linux 5.1 to 5.2 on Dell Latitude 5495,
Ryzen Pro 2700U. Graphical corruption, and/or the GUI will stop responding.
Magic SysRq is needed to reboot the computer.

kernel log contains the following bits when this happens:

[   44.921571] [drm:amdgpu_job_timedout] *ERROR* ring gfx timeout, signaled

Another confimation of same issue on HP Envy x360 15-bq181no with Ryzen 5 2500U
with Manjaro. Kernel option iommu=pt fixes it, didn't try other workarounds.

Your issue in particular is likely unrelated - it's an issue in userspace.

The bisected commit is the one that allowed xf86-video-amdgpu to start scanning
out DCC compressed buffers that mesa produces, with the caveat that mesa needs
a hook on present for the re-tile. My guess is that hook isn't running when you
aren't using "compositing".

I'm not sure if mesa or xf86-video-amdgpu have options yet to disable DCC or
not, but for that particular setup you'd probably want it disabled.

--- Comment #7 from Wiktor Kaczor <wiktoraleksanderkaczor@gmail.com> ---
I have the same problem using the Lenovo 530S-14ARR with Ryzen 5 2500U. 

The XFCE4 compositing makes the system immediately freeze as soon as I log in
on Manjaro with the 5.2.4-1 kernel.

On the 5.3rc2 kernel, I can enable it and it doesn't immediately hang without
recovery. That said, the compositing doesn't work and we have a lot of
corruption as soon as anything updates on screen.

The "iommu=pt" option didn't do anything for me in regards to reducing the
corruption.

I didn't know which logs to include so I didn't. Send reply with the names and
hopefully, approximate path of any logs to include.

Yeah, could be that radeonsi is missing cases where this hook needs to run (or
DCC needs to be disabled altogether).

Pierre or Marek, can you look into this?

I couldn't reproduce the problem (Ryzen 7 PRO 2700U laptop).

Could you list the version number of the various component involved (kernel,
mesa, xf86-video-amdgpu and libdrm) please?

Also can you reproduce the problem with another desktop environment?

Just rebuilt mesa, libdrm, and xf86-video-amdgpu from git this evening. The
kernel is the gentoo patched version of 5.2.6. The problem is not limited to
XFCE's window manager. This is what it looks like in Dolphin:

Does using "AMD_DEBUG=nodcc" Mesa environment variable help?

Could you capture an apitrace of the issue in Dolphin so I can reproduce more
easily?

It does. Exporting that in my ~/.profile makes the desktop usable.

It seems that the Dolphin issue is not related to the desktop graphics
corruption. I tested it again using a kernel that had my hack to under-report
the version number and saw the same rendering issues in Dolphin, but that
kernel doesn't require the nodcc environment variable.

Setting AMD_DEBUG="nodcc" system-wide via /etc/profile will help against GUI
freeze, but not against graphical corruption (screenshot attached).

It seems that the graphics corruption on my Dell Latitude 5495 with kernel 5.2
is a different issue. Kai-Heng Feng bisected and identified this in the Ubuntu
Launchpad tracker already.

Let's focus on this issue first.

Can you paste the output of: "AMD_DEBUG=info glxgears" please?

And would you be able to test other versions of Mesa to see if your issue could
be bisected (if it happens to be a Mesa problem)?

So, I've installed Compton as an alternative compositor on XFCE4 (I disabled
the internal one), it works rather well The only problem I could find so far is
that the graphics corruption persists when moving windows (the white blocky
stuff that appears around all moving elements). Although, It does clear up as
soon as I stop moving the window.

Alternatively, I was thinking of moving to using Wayland, however, XFCE4
doesn't seem to support it so that's not an option for me. Perhaps someone can
test that on their own system. Anyhow, I'm happy with the functionality of my
current albeit partial solution. I will continue to check in for a full
solution though.

I haven't had a lot of time to work on this, but I do have one more data point:
Mesa 19.1.4 has no corruption in Dolphin but still requires the nodcc
workaround with kernel 5.2.6.

The following applies to the graphics corruption seen in Dolphin:

    radeonsi: make gl_SampleMaskIn = 0x1 when MSAA is disabled

    gl_SampleMaskIn is 1 when R_028BE0_PA_SC_AA_CONFIG is 0, so this commit
rework the conditions
    controlling this register.

    Before it was set if the sctx->framebuffer had a sample count > 1.

    Now we still require this condition, but we also need either:
      - GL_MULTISAMPLE to be enabled
      - to be executing an operation that doesn't depends on GL state using
u_blitter.

    This fixes the arb_sample_shading/sample_mask piglit tests on radeonsi.

How old is XFCE in 16.04? I'm using 4.14, which was released this month. 

Here's a quote from the release notes: "The window manager received a slew of
updates and features, including support for VSync (using either Present or
OpenGL as backend) to reduce or remove display flickering, HiDPI support,
improved GLX support with NVIDIA proprietary/closed source drivers, support for
XInput2, various compositor improvements and a new default theme." Maybe older
versions of the window manager don't trigger the issue.

Either way, I have an extra SSD on the way. I should be able to swap that in to
the machine and figure out some directions for reproducing the bug from a clean
install.

It's hard to tell who's talking about which issue as there seems to be two or
even three different ones going on here.

I believe I'm seeing the originally reported issue as iommu=pt helps on my
2700U. Without it, I get heavy corruption throughout KDE. I'm running OpenSUSE
Leap 15.1 with kernel-default 5.2.10-1.g5878ee6. Going back to 5.1 also works.

Apparently, Lenovo released a new BIOS update for my laptop (Thinkpad E485)
today. The changelog mentions, "Sync IOAPICID in IVRS and APIC ACPI tables
(Linux)." I installed the update and removed both the ivrs_ioapic[32]=00:14.0
flag, as well as the iommu=pt flag from my kernel command line for testing. To
my surprise, the laptop booted just fine and from what I can tell, the
graphical corruption seems to be gone. In the meantime, the kernel and mesa
were updated a few times and I cannot pinpoint what, exactly, fixed my issues.

-> mesa 19.1.5
-> kernel 5.2.10.arch1-1
-> llvm-libs 8.0.1-3

amd_fix.sh

I've been having a problem with display corruption on Fedora using recent
updates. Here is my report on their bug tracker:

https://bugzilla.redhat.com/show_bug.cgi?id=1745380

I can confirm that when compiz is enabled, the system will lock up when it's
started. Adding "iommu=pt" to the kernel flags in grub2 will allow the system
to boot without freezing but the display is still corrupt.

Adding "AMD_DEBUG=nodcc" to the environment provides a complete workaround
(without the need for the kernel flag).

I've attached a file "amd_fix.sh" which if placed in /etc/profile.d/ will
provide a workaround until this can be fixed in the kernel or wherever the
problem is.

Using kernel 5.3.0 and mesa git with that patch:
* Graphics corruption in Dolphin is gone (without nodcc env variable)
* System lockup is gone (without nodcc env variable)
* Desktop corruption is still present (without nodcc env variable)
* Desktop corruption is gone (nodcc env variable set)

--- Comment #30 from William Bonnaventure <william.bonnaventure@gmail.com> ---
Fixed issue with a BIOS update on Lenovo E485 (v1.54 with AMD 2500U) with
Fedora 30 KDE.

I had an issue on previous BIOS that requires a kernel option to boot on all
kernels (ivrs_ioapic[32]=00:14.0). After BIOS update, this option is not needed
and there is no longer graphic corruption on Kernel 5.2+. This corruption was
impacting at least Firefox, dolphin and the Plasma Desktop.

KDE plasma 5.15.5
mesa 19.1.6
xorg-x11-drv-amdgpu 19.0.1
libdrm 2.4.99

As of my observation, the graphic corruption was introduced in the amdgpu
driver inside Kernel 5.2 and occurs only when forcing boot with the ivrs_ioapic
override.
