With a patch to mesa to expose rgb565 pbuffers even on a server with
only depth 24 and 32 visuals, fixes
dEQP-EGL.functional.render.single_context.gles2.rgb565_pbuffer. Those
pbuffers (or at least something renderable with 565) are required by
the current CTS for GLES3, and having the server support DRI3 on those
pixmaps means that we can avoid having a different path for EGL
pbuffers compared to pixmaps.

KMS drivers are not required to support GEM. In particular, vmwgfx
doesn't support flink and handles and names are identical.
Getting a bo name should really be part of a lower level API, if needed,
but in the mean time work around this by setting the name identical to
the handle if GEM isn't supported.
This fixes modesetting driver dri2 on vmwgfx.

When support for allocating GBM BOs with modifiers was added,
glamor_fd_from_pixmap() was changed so that it would return an error if
it got a bo with modifiers set from glamor_fds_from_pixmap(). The
problem is that on systems that support BOs with modifiers,
glamor_fds_from_pixmap() will always return BOs with modifiers.
This means that glamor_fd_from_pixmap() was broken entirely, which broke
a number of other things including glamor_shareable_fd_from_pixmap(),
which meant that modesetting using multiple GPUs with the modesetting
DDX was also broken. Easy reproducer:
- Find a laptop with DRI prime that has outputs connected to the
dedicated GPU and integrated GPU
- Try to enable one display on each using the modesetting DDX
- Fail
Since there isn't a way to ask for no modifiers from
glamor_fds_from_pixmap, we create a shared _glamor_fds_from_pixmap()
function used by both glamor_fds_from_pixmap() and
glamor_fd_from_pixmap() that calls down to the appropriate
glamor_egl_fd*_from_pixmap() function.

Hi,
I upgraded Xwayland and the assorted libraries from git masters today,
and noticed that glamor wouldn't work anymore on i.MX6/etnaviv. The
error was:
No provider of glVertexAttribDivisor found. Requires one of:
Desktop OpenGL 3.3
OpenGL ES 3.0
GL extension "GL_ANGLE_instanced_arrays"
GL extension "GL_ARB_instanced_arrays"
GL extension "GL_EXT_instanced_arrays"
GL extension "GL_NV_instanced_arrays"
The problem is that etnaviv offers GLSL 140 on GL 2.1 and glamor
rendering assumes that glVertexAttribDivisor() is always available on
GLSL>=130, which is not the case here. Forcing GLSL 120 makes glamor
work fine again on this platform. After chatting with ajax in
#xorg-devel, the following solution was proposed.
This is my first time of submitting a patch, so please excuse me and
advise if I'm doing it wrong ;)
Cheers

When compositing a no-reflect gradient, 'before' the gradient is empty,
but 'after' the gradient is padded with the final color. Both sides are
supposed to be empty.
This is fixed by moving the virtual stops to match the first and last
client-supplied stops for no-reflect gradients, then causing everything
'before' the initial virtual stop and 'after' the final virtual stop to
emit rgba(0,0,0,0). This does not impact gradients using the other
reflect modes.
