b678befb6e gl-renderer: Create a high priority context
EGL_IMG_context_priority allows the client to request that their
rendering be considered high priority. For ourselves, this is important
as we are interactive and any delay in our rendering causes input-output
jitter; a less than smooth user interactive. So if the driver supports
setting the context priority, try and create our EGLContext as high
priority. The driver may reject our request due to system restrictions,
in which case it will fallback to normal priority, but if successful it
will reschedule our rendering and all of its dependencies to execute
earlier, especially important when the GPU is being hogged by background
clients.

99ef816fd1 dmabuf: set modifier to invalid for not supporting clients
modifier_hi and modifier_lo are set to 0 by clients,
which are not supporting modifiers. Modifier attributes
of buffers of these clients set to 0 too in linux-dmabuf.c

import_simple_dmabuf function in gl-renderer.c compares
modifier attribute of the buffer with DRM_FORMAT_MOD_INVALID.
DRM_FORMAT_MOD_INVALID is equal to ((1ULL<<56) - 1).
Therefore, modifer 0 is accepted as valid. Then, the function
checks support for eglQueryDmaBufModifiersEXT.
If it is not supported import_simple_dmabuf function is returning
NULL.

This patch sets the modifier attribute to DRM_FORMAT_MOD_INVALID
for clients which are not supporting modifiers. Without this patch
linux-dmabuf protocol is not working for not supporting clients.

b040974398 gl-renderer: Set pitch correctly for subsampled textures
zwp_linux_dmabuf_v1 allows clients to pass an explicit pitch for each
plane, but wl_shm only takes a single pitch parameter; the pitch for
secondary planes must be inferred.

Multi-plane sub-sampled textures have partial width/height, e.g.
YUV420/I420 has a full-size Y plane, followed by a half-width/height U
plane, and a half-width/height V plane.

GStreamer's waylandsink - the only user of wl_shm YUV formats - expects
the implementation to follow the example of Xv and implicitly divide the
pitch for secondary planes by the subsampling factor. gl-renderer was
not doing this, and instead just using the (larger) stride provided by
the client for all planes in the buffer.

Fix gl-renderer to divide pitch by the subsampling factor when uploading
from subsampled SHM buffers into GL textures, also dividing co-ordinates
when doing offset partial uploads.

Tested with:
  $ gst-launch-1.0 videotestsrc ! waylandsink

df0e4b965f gl-renderer: Emit GPU rendering begin and end timeline timepoints
Use EGL fence sync objects to emit timepoints for the beginning and the
end of rendering on the GPU. The timepoints are emitted asynchronously
using the sync file fds associated with the fence sync objects. The sync
file fds are acquired using the facilities provided by the
EGL_ANDROID_native_fence_sync extension.

The asynchronous timepoint submissions are stored in a list in
gl_output_state until they are executed, and any pending submissions
that remain at output destruction time are cleaned up.

If timelining is inactive or the required EGL extensions are not
present, then GPU timepoint processing and emission are skipped.

Note that the GPU timestamps returned by sync files are in the
CLOCK_MONOTONIC clock domain, and are thus compatible with the
timeline timestamps (which also are in the CLOCK_MONOTONIC domain).

gl-renderer, simple-dmabuf-v4l: fix dmabuf y-invert
Invert the Y_INVERT flag for the EGL import fo dmabufs. This fixes
weston-simple-dmabuf-intel to show the same image on both GL-composited
and with direct scanout on a hardware plane. Before, the image would
y-flip when switching between these two cases. Now the orientation also
matches the color values written in simple-dmabuf-intel.c.

The GL-renderer uses the OpenGL convention of texture coordinates, where
the origin is at the bottom-left of an image. This can be observed in
texture_region() where the texcoords are inverted if y_invert is false,
since the surface coordinates have origin at top-left.  Both wl_shm and
dmabuf buffers have origin at the top-left.

When wl_shm buffer is imported with glTexImage2D, it gets inverted
because glTexImage2D is defined to read in the bottom row first. The shm
data is top row first. This incidentally also means, that buffer pixel
0,0 ends up at texture coordinates 0,0. This is now inverted compared to
the GL coordinate convention, and therefore gl_renderer_attach_shm()
sets y_inverted to true. This causes texture_region() to NOT invert the
texcoords. Wayland surface coordinates have origin at top-left, hence
the double-inversion.

Dmabuf buffers also have the origin at top-left. However, they are
imported via EGL to GL, where they should get the GL oriented
coordinates but they do not. It is as if pixel 0,0 ends up at texcoords
0,0 - the same thing as with wl_shm buffers. Therefore we need to invert
the invert flag.

Too bad EGL_EXT_image_dma_buf_import does not seem to specify the image
orientation. The GL spec implied result seems to conflict with the
reality in Mesa 11.2.2.

I asked about this in the Mesa developer mailing list. The question with
no answers:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120249.html

that supports this patch.

simple-dmabuf-v4l is equally fixed to not add Y_INVERT. There is no
rational reason to have it, and removing is necessary together with the
GL-renderer change to keep the image the right way up. This has been
tested with VIVID.

36d699a164 gl-renderer: Make dummy surface current after all outputs are gone
When all outputs are gone, there are no current read/write
surfaces associated with a context. This makes the previously
created dummy surface current until an output gets attached
to avoid any potential crashes.

v2:

f0c3a1c112 gl-renderer: move check_extension() to shared/
... prefixing it with a "weston_". This way we can reuse it across the
board, instead of the current strstr. The latter of which can give us
false positives, thus it will be resolved with next commit(s).
