Thanks for the report, fixed in Git master (and should get backported to a
future 17.3.y release):

Thanks a lot, Michel!  I confirmed that 255573996 plus the linked patch works
for me as well.

--- Comment #14 from eric vz  ---
Thanks, Michel.  On a hanging call to glxinfo, dri2_validate_usage is being
called from gbm_dri_bo_import, which gets parameters of a 100x100 FD image
buffer for usage 5 (scanout | rendering).  However, the image texture winds up
with is_displayable = 0, so si_check_resource_capabilities returns false,
gbm_dri_bo_import destroys the image, and glxinfo hangs.  I confirmed that if I
set variable usage = 0 the problem does not occur.  I have not yet been able to
trace where the texture flags are set, but I got far enough to find that
they're being read from the image buffer as metadata.  

However, it occurs to me that as a newcomer to the domain (e.g., I had to
google what a scanout is), I don't know the real problem:

* Should usage include scanout?
* Should the image metadata include is_displayable? 
* Should the null return from gbm_dri_bo_import cause the caller to hang?

Either point 1 or point 2 seems like it must be wrong, and might be the easiest
fix. Point 1 seems the stronger case, since glxinfo doesn't actually draw
anything as far as I'm aware. Since Firefox, Chromium, and other apps also seem
to fail on this, I'm expecting to find some kind of common initialization code
that does it.  Will report back when I get time to dig.  Or, if anyone knows
better than I do which avenue to pursue, I'm happy to be redirected.  I don't
expect to have time to look at this until the weekend.

It's not called in the client but in the Wayland compositor process, or maybe
in Xwayland.

--- Comment #12 from eric vz  ---
Subsequent bisects (starting at different ranges so different commits would be
tested) have led me to the same place. No idea why I thought 255573996 worked
for a while; all new builds from it break for me.  I have Pacman packages for
every build I've made if anyone would find them useful.

I narrowed the problem to the final return statement by replacing it with
"return true;" which resulted in a working build.  I also tried to rule out
side-effects from the call by adding "bind =
screen->check_resource_capability(screen, image->texture, bind) ? 1 : 0;"
before the return true so the method would be called but its return value
ignored, assuming the compiler is not smart enough to optimize that out.  That
build worked too. 

I assume that capability check must sometimes be returning false in some
unexpected situations, and something is not handling that.  I tried making a
debug build of mesa-demos, then gdb glxinfo and set a breakpoint on
dri2_validate_usage, but that method appears not to be called before the
process hangs.  I assume something during system startup calls it, caches the
result, and leads to these issues downstream?

If anyone has any guidance on next steps, I'd appreciate it.

I can confirm that switching from radeon to amdgpu on

03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Pitcairn XT [Radeon HD 7870 GHz Edition]

Device: AMD Radeon HD 7800 Series (PITCAIRN / DRM 3.19.0 / 4.14.11-1-ARCH, LLVM
5.0.1) (0x6818)

fixes the issue.

Following up on this, it looks like my bisect wa bad.  I retried commit
255573996cc997cb61be9adad3e8fcaa78db5d1f and it works fine. 

I will re-bisect to find the real offending commit and report when I have an
answer.

--- Comment #9 from Jonathan Williams  ---
I also have this problem on Arch Linux with a Radeon HD 7770, mesa 17.3.1-2,
gnome-shell 3.26.2+9+ga3736d3a3-1.  The Gnome Wayland session starts, but
several XWayland apps (Firefox, Thunderbird, steam client) do not.  glxinfo
shows no response when run, as reported above.

Downgrading to mesa 17.2.6 appears to fix it, but for this card I can also work
around it by switching to the amdgpu kernel module instead of the default
radeon, which appears to resolve the issues under mesa 17.3.

Hung glxinfo backtrace - mesa 17.3.1-1

On the chance you'd want to see a newer version, I built mesa 17.3.1-1 (with
debug symbols this time!) and have the same issue.  Backtrace attached.

I can't reproduce this with weston or gnome-shell.

Which Wayland compositor and which version of Xwayland are you using?

Can you get a gdb backtrace of glxinfo when it hangs?

Working on narrowing down the source of the issue, I've found so far that
17.2.7 builds work fine (though I had to change --enable-omx-bellagio back to
--enable-omx), and 17.3.0-rc3 does not.  I'll try an -rc1 build, then I may be
on to learning how to package from a locally bisected git.

Similar experience here on Arch Linux with a Radeon HD 8870M / R9 M270X/M370X. 
Firefox hangs on launch before drawing a window, and Chromium won't start
either unless I --disable-gpu.  Similar strace results, no amdkfd errors.

Archive package 2017/12/15/extra/os/x86_64/mesa-17.2.6-1 works fine,
2017/12/16/extra/os/x86_64/mesa-17.3.0-2 doesn't.  Kernel 4.9.69-1-lts #1 SMP
Thu Dec 14 19:51:07 CET 2017 x86_64 GNU/Linux, if it matters.

I notice the Arch maintainer changed the build arg --enable-omx to
--enable-omx-bellagio in this release.  I know nothing of Mesa's build process,
this being my first encounter, but I thought that might be useful to mention in
case it's relevant.

https://bugs.freedesktop.org/show_bug.cgi?id=104306

Bug ID: 104306
   Summary: Mesa 17.3 breaks Firefox and other Xwayland apps on
AMD HD7750
   Product: Mesa
   Version: 17.3
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/radeonsi
  Assignee: dri-devel@lists.freedesktop.org
  Reporter: mesabu...@p33.org
QA Contact: dri-devel@lists.freedesktop.org

On latest stable Archlinux with AMD HD7750, Mesa 17.3 breaks Firefox,
Libreoffice, mpv with X11 backend and Chromium (when running WebGL).

Launching firefox or glxinfo from command line results in no response and no
crashes. There are no errors in dmesg or journalctl, except Probe failed with
amdkfd, but blacklisting amdkfd doesn't solve the issue. Using strace on
firefox there are system interrupted notices. Chromium works, but opening any
WebGL page freezes Chromium. mpv with X11 backend shows Bad Drawable, server
failed to allocate resource.

Downgrading to mesa 17.2.6 solves the issue.
