Emil Velikov 744c419cb4 glamor: check for non NULL pixmap at close_screen
DDX such as Xorg, Xwayland & Xephyr do not destroy the pixmap before
they call into CloseScreen. At the same time Xvfb (support for glamor
coming with later commit) do.

As such the pixmap will be NULL and we'll crash out.

Emil Velikov f3ab3d0c61 glamor_egl: disable modifiers via glamor_init()
Currently we parse through xf86Info.debug to check if we the modifiers
should be disabled. Handle that within DDX and pass GLAMOR_NO_MODIFIERS
into the glamor_init() flags.

This allows individual DDX control over the setting - say when modifiers
are woking OK with one implementation and not the other.

Most importantly, this removes the final xf86 piece from the codebase.

Move from the xf86 specific ScrnInfoRec::privates, to the dix private

former within the existing CloseScreen.

If a pixmap is not exportable, `glamor_gbm_bo_from_pixmap()` would fail

  (EE) modeset(0): present flip failed

Adam Jackson 766bf01b21 glamor: Fix more fallback paths with non-GXcopy rop with GLES
Desktop GL can handle arbitrary rops here, GLES can't. The switch
statement attempts to optimize some cases that GLES can still handle if
we precompute the right pixel value, but we were then throwing that

xts-render passes against glamor+gles.

Eric Anholt 8702c938b3 glamor: Introduce a central place for our pixmap format/type handling.
We had various helper functions trying to come up with the
internalformat/format/type/render formats for pixmaps, and it's much
nicer to just detect what those should be once at startup.  This gives
us a chance to do the right thing for GLES.

It also, notably, fixes our format/type for depth 15 and 16 setup for
desktop GL, so that we actually allocate 16bpp (GL_RGB/565) on most
drivers instead of 32bpp (GL_RGB/UBYTE).

GLES still has regressions over desktop (2 regressions in llvmpipe
XTS, many in rendercheck), but I think this is a good baseline.

Paul Kocialkowski c98c7709c6 glamor: Propagate FBO allocation failure for picture to texture upload
When uploading a picture to a texture, glamor_upload_picture_to_texture
calls glamor_pixmap_ensure_fbo to ensure that there is backing FBO.
The FBO will be allocated if the picture's drawable pixmap does not have
one already, which can fail when there is no GL memory left.

glamor_upload_picture_to_texture checks that the call succeeded and will
enter the failure path if it did not. However, unlike many other
functions in glamor, this one has ret set to TRUE initially, so it needs
to be set to FALSE when a failure happens.

Otherwise, the error is not propagated and the failure path return TRUE.
This leads to a fault when trying to access the FBO pointer later on.

Adam Jackson 0a9415cf79 glamor_egl: Don't initialize on llvmpipe
Mesa started supporting GL_OES_EGL_image on llvmpipe in 17.3, after this
commit:

    commit bbdeddd5fd0b797e1e281f058338b3da4d98029d
    Author: Gurchetan Singh <gurchetansingh@chromium.org>
    Date:   Tue Aug 1 14:49:33 2017 -0700

        st/dri: add drisw image extension

That's pretty cool, but it means glamor now thinks it can initialize on
llvmpipe. This is almost certainly not what anyone wants, as glamor on
llvmpipe is pretty much uniformly slower than fb.

This fixes both Xorg and Xwayland to refuse glamor in such a setup.
Xephyr is left alone, both because glamor is not the default there and
because Xephyr+glamor+llvmpipe is one of the easier ways to get xts to
exercise glamor.

The (very small) downside of this change is that you lose DRI3 support.
This wouldn't have helped you very much (since an lp glamor blit is
slower than a pixman blit), but it would eliminate the PutImage overhead
for llvmpipe's glXSwapBuffers. A future change should add DRI3 support
for the fb-only case.

Lyude Paul 186a21c4ba glamor: Unbreak glamor_fd_from_pixmap()
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.

Lukas F. Hartmann 7437b6dbde glamor_init: clamp GLSL to 120 if platform doesn't have instanced arrays
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 ;)

Daniel Stone 23c67987a3 glamor: Add fd_from_pixmap hook
Add a fd_from_pixmap (singular) hook to go with fds_from_pixmap, which
will ensure that the pixmap is allocated without modifiers and is thus
exportable to non-modifier-aware clients.

This makes it possible to run a compositing manager on an old GLX/EGL
stack on top of an X server which allocates internal buffer storage
using exotic modifiers from modifier-aware GBM/EGL/KMS.

When compositing a no-reflect gradient, 'before' the gradient is 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

Michel Dänzer 7c88977d33 glamor: Store the actual EGL/GLX context pointer in lastGLContext
Fixes subtle breakage which could sometimes trigger after a server reset
with multiple screens using glamor:

Screen A enters glamor_close_screen last and calls various cleanup
functions, which at some point call glamor_make_current to make sure
screen A's GL context is current. This sets lastGLContext to screen A's
&glamor_priv->ctx. Finally, glamor_close_screen calls
glamor_release_screen_priv, which calls free(glamor_priv).

Later, screen B enters glamor_init, which allocates a new glamor_priv.
With bad luck, this can return the same pointer which was previously
used for screen A's glamor_priv. So when screen B's glamor_init calls
glamor_make_current, lastGLContext == &glamor_priv->ctx, so MakeCurrent
isn't called for screen B's GL context, and the following OpenGL API
calls triggered by glamor_init mess up screen A's GL context.

The observed end result of this was a crash in glamor_get_vbo_space
because glamor_priv->vbo didn't match the GL context, though there might
be other possible outcomes.

Assigning the actual GL context pointer to lastGLContext prevents this
by preventing the false negative test in glamor_make_current.
