Problem with Radeon Pro WX 9100

[Marcello Blancasio]

Hello.

I received a report claiming there's a problem with Radeon Pro WX 9100.

glxgears fails with X error BadAlloc (insufficient resources for operation) on operation X_GLXCreatePbuffer.

Gnome desktop appears badly rendered.

Driver xserver-xorg-video-amdgpu 18.1.99+git20190207-1 is installed. Is AMDGPU "Pro" required? Unfortuantely it is not provided for Debian 10.

Thanks.

Marcello.

I finally have a Radeon Pro for testing, and working through some of these issues is on my “things to do” list. In the meantime, try setting VGL_FORCEALPHA=1.

VGL_FORCEALPHA fixed glxgears, while desktop is still uncorrectly rendered. Tried also VGL_WM=1.

Hello.

I received a report claiming there's a problem with Radeon Pro WX 9100.

glxgears fails with X error BadAlloc (insufficient resources for operation) on operation X_GLXCreatePbuffer.

Gnome desktop appears badly rendered.

Driver xserver-xorg-video-amdgpu 18.1.99+git20190207-1 is installed. Is AMDGPU "Pro" required? Unfortuantely it is not provided for Debian 10.

Thanks.

Marcello.

OK, I'm still working on an appropriate fix/workaround to make the amdgpu drivers pass the VirtualGL Faker unit test (fakerut), so I'll let you know once that work is completed.  Hopefully it will fix the remaining issues.

Unfortunately, my research (using fakerut in the VirtualGL source)
revealed some conformance issues with the AMDGPU driver. These issues
do not exist with Mesa, Catalyst (the legacy ATI/AMD proprietary
driver), or the nVidia proprietary driver. At the moment, the AMDGPU
driver is unsupportable until the moderate and show-stopping issues
below are resolved.

------------------------------

Issue #1:
glXGetSelectedEvent() triggers a BadDrawable X11 error rather than a
GLXBadDrawable X11 error when passed an invalid GLX drawable handle.

Severity:
Minor

Temporary workaround:
0001-fakerut-Don-t-test-glXGetSelectedEvent-err-code.patch

Reference:
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXGetSelectedEvent.xml
"GLXBadDrawable is generated if draw is not a valid window or a valid
GLX pixel buffer."

------------------------------

Issue #2:
glXSwapBuffers() does not actually swap the buffers of a double-buffered
Pbuffer.

Severity:
Show-stopper (without this functionality, there is no way that VirtualGL
can work properly)

Test program reproducing the issue:
pbdbtest.c

Temporary workaround:
0003-Faker-Buffer-swap-Pbuffers-using-glCopyPixels.patch

Reference:
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXCreatePbuffer.xml
"GLXPbuffers contain the color and ancillary buffers specified by
config. It is possible to create a pixel buffer with back buffers and
to swap those buffers using glXSwapBuffers."

------------------------------

Issue #3:
GLX_DRAWABLE_TYPE is implemented using exclusive rather than inclusive
matching in glXChooseFBConfig().

Description:
If you specify GLX_DRAWABLE_TYPE=GLX_PBUFFER_BIT|GLX_PIXMAP_BIT, then
the AMDGPU implementation of glXChooseFBConfig() will not return any
GLXFBConfigs that support window rendering. That is incorrect behavior,
since GLX_DRAWABLE_TYPE is supposed to be inclusive, not exclusive.
Because AMDGPU does not return any GLXFBConfigs that have GLX_WINDOW_BIT
set, the set of GLXFBConfigs that VirtualGL is able to obtain from the
driver contains only R/G/B 10/10/10 GLXFBConfigs.

Severity:
Moderate

Temporary workaround:
0002-Faker-Only-choose-FB-configs-w-GLX_WINDOW_BIT-set.patch

Reference:
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXChooseFBConfig.xml
"GLX_DRAWABLE_TYPE: Must be followed by a mask indicating which GLX
drawable types the frame buffer configuration must support."
(This language implies inclusive rather than exclusive matching, because
it doesn't say that the frame buffer configuration must *only* support
those GLX drawable types.)

------------------------------

Issue #4:
GLX_X_RENDERABLE is incorrectly implemented.

Description:
All GLXFBConfigs returned by the AMDGPU implementation have
GLX_X_RENDERABLE set, even though only some GLXFBConfigs have an X
visual attached. That is incorrect behavior, and it makes it difficult
to work around Issue #3 in a robust manner.

Severity:
Moderate

Workaround:
None

Reference:
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXChooseFBConfig.xml
"GLX_X_RENDERABLE: Must be followed by True or False. If True is
specified, then only frame buffer configurations that have associated X
visuals (and can be used to render to Windows and/or GLX pixmaps) will
be considered. The default value is GLX_DONT_CARE."

------------------------------

Issue #5:
glXCopyContext() triggers a GLXBadContextTag X11 error.

Description:
This also happens with the legacy Catalyst drivers.

Severity:
Minor

Workaround:
Pass -nocopycontext to fakerut.

Reference:
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXCopyContext.xml
does not indicate that a GLXBadContextTag error can occur due to
incorrect input.
https://www.khronos.org/registry/OpenGL/specs/gl/glxencode1.3.pdf
suggests that a GLXBadContextTag error is a low-level failure within the
implementation.

------------------------------

Issue #6:
glXQueryContext(..., GLX_RENDER_TYPE, ...) returns a render type of 0 if
the context was created with a render type of GLX_RGBA_TYPE.

Severity:
Moderate

Test program reproducing the issue:
queryctx.c

Workaround:
None

Reference:
https://www.khronos.org/registry/OpenGL-Refpages/gl2.1/xhtml/glXQueryContext.xml
"GLX_RENDER_TYPE: Returns the rendering type supported by ctx."

[Marcello Blancasio]

Thank you. Do you think that using driver "AMDGPU Pro" rather than just "AMDGPU" would it make any difference?

> an email to virtual...@googlegroups.com

[DRC]

I don't know.  I'm pretty sure that my testing was with the AMDGPU Pro driver.  I am not sure how to test the fully-OSS version of the driver.  I have communicated my findings to AMD, who are looking into the issues.
