                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: devurandom@gmx.net
        QA Contact: dri-devel@lists.freedesktop.org

I was Alt+Tab-ing through the open windows, when KWin crashed.  The backtrace
ends in Mesa.  I am using version 17.2.2 (s.b.).

I now also have this card plugged into the system:

The monitor is still connected to the other card (comment #1), though.

Thank you for the report!

Can you try with Mesa from git master?

The issue is that in Mesa 17.2.2 (which you have according to glxinfo),
si_state_draw.c:1305 corresponds to

   1304                         index_offset -= start_offset;
   1305                 } else if (sctx->b.chip_class <= CIK &&
   1306                            r600_resource(indexbuf)->TC_L2_dirty) {

and it's basically impossible to get a crash there, so I suspect the Gentoo
build actually applies some other patches.

Something random you could try is starting KWin with GALLIUM_THREAD=0.

This is the ebuild:
https://gitweb.gentoo.org/repo/gentoo.git/tree/media-libs/mesa/mesa-17.2.2.ebuild

Patches would be listed in a PATCHES variable or applied in src_prepare().  The
ebuild has only eapply_user there, which would apply patches in
/etc/portage/patches/media-libs/mesa (or a version specific directory), which I
don't have.  Hence I believe there are no patches applied on my system.

I will extract the sources again and will try to attach GDB, while DrKonqi
(KDE's bug-reporting tool) has the process stopped, the next time I reproduce
the crash in the coming days.

I will also install using the 9999 / git ebuild and see whether I can reproduce
there.

Some more information: It does not immediately happen after login. I also tried
to trigger it with maybe more uncommon things like running Steam (and thus
Natural Selection 2) with DRI_PRIME=1, but that did not trigger the crash
either. I had the crash several times in the past, so I first need to find a
way to reproduce it more reliably.

That was, because KWin automatically falls back to software rendering, when the
OpenGL backend crashes to often.  OpenGL is now enabled again, and I can again
perfectly reproduce the crash on every Alt+Tab.

This is what I got from GDB, after extracting the Mesa sources (ebuild ...
preprare) and attaching to the process:

FYI Mesa 17.2.x is EOL, so it might be better to check if 17.3.3 and master
still have the issue.

I can't reproduce the issue currently. What is weird, since it didn't work for
months.

Maybe it's working now again because I deleted the $HOME/.cache content?

Could someone with the same problem do the same to see if it works afterwards
as well for him again?

My bug has been disappeared.  I use Fedora  and there ara 2 different X11
drivers.
The xorg-x11-drv-ati and xorg-x11-drv-amdgpu. I deleted the amdgpu x11 driver,
and install the ati x11 driver. According to lsmod my system still use the
amdgpu module.

The xorg ati driver is for the radeon kernel module.
The xorg amdgpu driver is for the amdgpu kernel module.

If the xorg driver is missing for the respective kernel module, the X server
will use the generic xorg modesetting driver instead. The behavior might be the
same because the modesetting driver has similar capabilities as the hw-specific
drivers.

My mistake...I  took an other look on the system, and the KDE scale method was
set to smooth (The default is accurate). This is reproducable 
System > compositor > scale method > accurate = crash
System > compositor > scale method > smooth or crisp = Can Alt + Tab without
crash.
So you are right, the different X11 driver doesn't solve the problem.

Since a patch that fixes this landed and 17.x is out of support I'm marking
this fixed.
