Dor Askayo 0e9a0c203c xwayland: clear pixmaps after creation in rootless mode
When a pixmap is created with a backing FBO, the FBO should be cleared
to avoid rendering uninitialized memory. This could happen when the
pixmap is rendered without being filled in its entirety.

One example is when a top-level window without a background is
resized. The pixmap would be reallocated to prepare for more pixels,
but uninitialized memory would be rendered in the resize offset until
the client sends a frame that fills these additional pixels.

Another example is when a new top-level window is created without a
background. Uninitialized memory would be rendered after the pixmap is
allocated and before the client sends its first frame.

This issue is only apparent in OpenGL implementations that don't zero
the VRAM of allocated buffers by default, such as RadeonSI.

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.

former within the existing CloseScreen.

Note: we need to ensure that the screen private is unset and the screen
callbacks are restored in our CloseScreen function.

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.

Daniel Stone 1b9fa3b64c glamor: Track if BO allocation used modifiers
Keep track of whether or not we fed modifiers into GBM when we allocated
a BO. We'll use this later inside Glamor, to reallocate buffer storage
if we allocate buffer storage using modifiers, and a non-modifier-aware
client requests an export of that pixmap.

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.

Eric Anholt 51984dddfc glamor: Delay making pixmaps shareable until we need to.
If a pixmap isn't getting exported as a dmabuf, then we don't need to
make an EGLImage/GBM bo for it.  This should reduce normal pixmap
allocation overhead, and also lets the driver choose non-scanout
formats which may be much higher performance.

On Raspberry Pi, where scanout isn't usable as a texture source, this
improves x11perf -copypixwin100 from about 4300/sec to 5780/sec under
xcompmgr -a, because we no longer need to upload our x11perf window to
a tiled temporary in order to render it to the screen.
