Blocklisted; failure code BLOCKLIST_FEATURE_FAILURE_SOFTWARE_GL

  • It should be "mesa/v3d".
  • Failing at OGL3.2 might made it think it's using software gl although GLES is hardware.
  • Let Wayland and X11 behave the same: Enable X11_EGL by default for this driver (Mesa baseline == Mesa 10). It enables WebGL2 support.
  • (Enabling WebRender depends on fixing the PBO problem. HW WR performs better than SW WR.)

Can you run the test program from bug 1731480 comment 15 in this setup and post the out? Also with LIBGL_ALWAYS_SOFTWARE=1 for comparison?

GL_RENDERER of es2_info differs between with LIBGL_ALWAYS_SOFTWARE=1 (llvmpipe (LLVM 11.0.1, 128 bits)) and without (V3D 4.2).

(Icenowy Zheng from bug 1721053 comment 4)

It's a GPU w/o display capability, and use DRM PRIME to output to another display-only DRM device.

In this case, there is /dev/dri/card[01], card0 being the display-only device and card1 being the renderonly device; renderD128 is bound to card1, but when doing DRI it's still using /dev/dri/card0 (Mesa will notice that it's a display-only device and try to probe renderonly device, and thus open renderD128)

My Macbook has card0 and renderD128, but the Raspberry Pi 4 additionally has a card1.

$ ls -l /dev/dri

Thanks, things start to make sense to me.

  • It should be "mesa/v3d".

Per comment 2 and the linked Mesa MR (https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/9697) it makes sense that we detect software rendering here. So this requires more recent Mesa to get fixed. It would, however, probably make sense to explicitly check for EGL_MESA_device_software to not accidentally detect software rendering. Will create a patch for that.

  • Failing at OGL3.2 might made it think it's using software gl although GLES is hardware.

I don't think so. The context creation happens long after our hardware detection in glxtest. With bug 1644606 in place we could, however, make these targets (e.g. ARM builds) prefer GLES over GL to avoid the noise of the warnings.

  • Let Wayland and X11 behave the same: Enable X11_EGL by default for this driver (Mesa baseline == Mesa 10). It enables WebGL2 support.

Looks like this won't work, see above.

  • (Enabling WebRender depends on fixing the PBO problem. HW WR performs better than SW WR.)

So you did confirm that disabling gfx.webrender.pbo-uploads fixes the issues? And are the glitches you are seeing the same like the ones reported in https://gitlab.freedesktop.org/mesa/mesa/-/issues/4620? If so, that's likely a good hint for the Mesa devs.
I don't see Android blocking that feature on any devices, which too me sounds like it should work.

Yes, the Pi is a "split render/display SoC" and has a kms read only device. This will likely be an issue for DMABUF detection (bug 1730936), because our normal detection likely doesn't work there and the new extension for it (EGL_EXT_device_drm_render_node) does not yet get exposed on such devices, at least not in the original MR (https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11797). But that's again not our job and should be fixed by Mesa going forward.

Yes, that's what I meant with recognize "mesa/v3d": There needs to be a rule that Firefox doesn't classify v3d (GL_RENDERER: V3D 4.2) as software GL.
EGL_MESA_device_software is shown for V3D although hardware GL is definitely used.
LIBGL_ALWAYS_SOFTWARE=1 is incredible slow in comparison.

WR/v3d (smoother scrolling) > SW WR > WR/llvmpipe

With bug 1644606 in place we could, however, make these targets (e.g. ARM builds) prefer GLES over GL to avoid the noise of the warnings.

Nice to have, but not required. The warning is no problem.

  • Let Wayland and X11 behave the same: Enable X11_EGL by default for this driver (Mesa baseline == Mesa 10). It enables WebGL2 support.

Looks like this won't work, see above.

I don't understand, why would this not work? I'm using it.
GLX is OGL2.1, that's WebGL 1-only.
Wayland would already try to use WebGL/EGL/Mesa with Mesa >= 10. https://searchfox.org/mozilla-central/rev/d21e359bd26dd0a7ba216472184d6fed8f0afd48/widget/gtk/GfxInfo.cpp#649

  • To have the same on Wayland and X11, I assume such a rule would be needed:

    APPEND_TO_DRIVER_BLOCKLIST_EXT(
    OperatingSystem::Linux, ScreenSizeStatus::All, BatteryStatus::All,
    DesktopEnvironment::All, WindowProtocol::All, DriverVendor::MesaV3d, // <----
    DeviceFamily::All, nsIGfxInfo::FEATURE_X11_EGL,
    nsIGfxInfo::FEATURE_ALLOW_ALWAYS, DRIVER_GREATER_THAN_OR_EQUAL,
    V(10, 0, 0, 0), "FEATURE_ROLLOUT_X11_EGL_MESA_V3D", "Mesa 10.0.0.0");

  • Or we lower minimum required EGL/Mesa version for all users to 20 as a next step. That seems easier and better. It's fine on Debian oldstable: bug 1730768 comment 6.

  • (Enabling WebRender depends on fixing the PBO problem. HW WR performs better than SW WR.)

So you did confirm that disabling gfx.webrender.pbo-uploads fixes the issues?
And are the glitches you are seeing the same like the ones reported in https://gitlab.freedesktop.org/mesa/mesa/-/issues/4620?
I don't see Android blocking that feature on any devices, which too me sounds like it should work.

Yes. I assume the problem lies in an aspect of it.
It looks far worse for me: bug 1738816
There are some specific config rules, there is even a rule for Android Mesa:
https://searchfox.org/mozilla-central/rev/d21e359bd26dd0a7ba216472184d6fed8f0afd48/gfx/wr/webrender/src/device/gl.rs#1655-1718

I don't understand, why would this not work? I'm using it.

The thing is that older Mesa versions explicitly mark this driver as a software one by exposing EGL_MESA_device_software. This is an external bug that I personally wouldn't want to work around with special rules if instead distros can just update their Mesa version (or backport the fix). That's the job of distro maintainers.

Do you think you could install a recent Mesa version on your device, ideally directly from git? It would be great to know how the current status of the driver looks like, not that of a year ago (also regarding the PBO bug).

Severity: -- → S3

Gnome X11 / Raspberry Pi OS 64-bit (Debian Stable + rpi repo) + Mesa 21.2.6 from Debian Testing also needs gfx.webrender.pbo-uploads:false for HW WR.
(Next step will be trying out 21.3.0~rc5-1 from Debian experimental.)

The device is still detected as "mesa/software-unknown" / FEATURE_FAILURE_SOFTWARE_GL.
gfx.webrender.reject-software-driver:false does not help, it is the second of two blocking mechanisms.

bug 1736267 comment 5 caused FEATURE_FAILURE_OPENGL_LESS_THAN_3.
gfx.egl.prefer-gles.enabled:true does not help.

  • Detected as software
  • FEATURE_FAILURE_OPENGL_LESS_THAN_3
  • gfx.webrender.pbo-uploads:false required for HW WR correctness

Does running with MESA_GL_VERSION_OVERRIDE=3.0 bypass the FEATURE_FAILURE_OPENGL_LESS_THAN_3 issue? Looks like d3d is the only mesa driver exposing GLES 3 but not GL 3.0.
I'm slightly unsure if it's worth to fix that check as long as the state of that driver is so bad. OTOH we should make it as easy as possible for driver devs to work on it.

As for the software part: will look into that now.

Keywords: leave-open

Mesa explicitly advertises the EGL_MESA_device_software extension
when appropriate. Only ever set MESA_ACCELERATED when that is the
case to avoid confusion around edge-cases and driver bugs.

Assignee: nobody → robert.mader
Status: NEW → ASSIGNED

We have a custom render node discovery code (needed for DMABUF) that
predates the EGL_DRM_RENDER_NODE_FILE_EXT extension. It has additional
value that it helps us discover the right vendor and device ID on
multi-GPU setups (there's a EGL extension far that backing, but
not ready yet).
In case our custom code fails - notably split display/render SoCs,
which are common in the ARM world - lets use
EGL_DRM_RENDER_NODE_FILE_EXT as fallback. This will ensure we
get a valid render node path on all devices, assuming the driver
supports that extension right. These SoCs are usually no multi-GPU
systems. If they are, we still don't get the right IDs - but an
extension for that is in the making.

Note: Mesa does not implement this right for such SoCs, i.e. it
will fail just as our own custom code. However, there's a MR in
review - once it lands, things should start working, see
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/12796

Jan, can I ask you to test latest nightly on bookworm/with Mesa 22.2.0~rc1? It should work in most regards now - but it would be great to have an about:support. And important to know if there are still rendering issues with HW-WR. Right now after bug 1783924 HW-WR is shipping to release, but we might want to block it a bit longer on v3d.

SW WR is default because of FEATURE_FAILURE_OPENGL_LESS_THAN_3

That plus the annoying warning about failed context creation should be possible to fix by choosing GLES first by default. Will create a patch for that.

Not fixed with try build from bug 1784453 comment 8 and a fresh profile.
gfx.egl.prefer-gles.enabled is true by default, but:

"gfx.blacklist.webrender.failureid": "FEATURE_FAILURE_OPENGL_LESS_THAN_3",
"gfx.blacklist.webrender": 4,

"windowLayerManagerType": "WebRender (Software)",

"status": "blocklisted",
"message": "No qualified hardware"

And fall back to a 2.x context otherwise.

Most drivers will create a 3.x/4.x context when setting the major
version to 2, however in cases where that's not supported we need to
actively ask for 3.0 in order to determine up-front that HW-WR is not
supported. We do so in order to avoid flodding users with such hardware
with error messages (or to have every device ID in the database,
alternatively).

We don't need to care about 1.x as we actively disable all GL
functionality in that case.

(In reply to Robert Mader [:rmader] from comment #26)

The patch above should fix that, can you give it a try? https://treeherder.mozilla.org/jobs?repo=try&revision=8b5a20bac9dad2364f6d715b9c1500b4514412d5
