Subject: [PATCH 1/7] gl-renderer: Add EGLDevice enumeration support
X-NVConfidentiality: public
EGLDevice provides means to enumerate native devices.
In preparation for follow-on changes to support frame presentation
through EGLDevice+EGLOutput, this change adds both
gl_renderer_get_devices() and gl_renderer_get_drm_device_file()
functions which will help to enumerate EGLDevices and match them to DRM
devices.

Subject: [PATCH 2/7] gl-renderer: Add support for EGLDevice composited frame
presentation
X-NVConfidentiality: public
EGLDevice provides means to enumerate native devices, and then create
an EGL display connection from them.
Similarly, EGLOutput will provide means to access different
portions of display control hardware associated with an EGLDevice.
For instance, EGLOutputLayer represents a portion of display
control hardware that accepts an image as input and processes it
for presentation on a display device.
EGLStream implements a mechanism to communicate frame producers and
frame consumers. By attaching an EGLOutputLayer consumer to a stream,
a producer will be able to present frames on a display device.
Thus, a compositor could produce frames and feed them to an
EGLOutputLayer through an EGLStream for presentation on a display
device.
This change adds required logic to support presentation approach
described above.
Note that some unpublished EGL extensions were needed:
- EGL_NV_stream_attrib:
https://github.com/aritger/eglstreams-kms-example/blob/master/proposed-extensions/EGL_NV_stream_attrib.txt
- EGL_EXT_stream_acquire_mode:
https://github.com/aritger/eglstreams-kms-example/blob/master/proposed-extensions/EGL_EXT_stream_acquire_mode.txt
- EGL_NV_output_drm_flip_event:
https://github.com/aritger/eglstreams-kms-example/blob/master/proposed-extensions/EGL_NV_output_drm_flip_event.txt

Subject: [PATCH 3/7] gl-renderer: Add EGL client support for EGLStream frame
presentation
X-NVConfidentiality: public
By attaching a GLTexture consumer to a stream, a producer (wayland EGL
client) could feed frames to a texture, which in turn can be used by a
compositor to prepare the final frame to be presented.
This change adds required logic to support presentation approach
described above.
Note that some unpublished EGL extensions were needed:
- EGL_NV_stream_attrib:
https://github.com/aritger/eglstreams-kms-example/blob/master/proposed-extensions/EGL_NV_stream_attrib.txt
- EGL_WL_wayland_eglstream:
https://github.com/aritger/eglstreams-kms-example/blob/master/proposed-extensions/EGL_WL_wayland_eglstream.txt

Subject: [PATCH 4/7] compositor-drm: Gracefully handle vblank and flip invalid
timestamps
X-NVConfidentiality: public
Instant query for vblank timestamp may always fail, resulting in
never scheduling a full repaint in drm_output_start_repaint_loop().
Additionally, timestamp provided in page_flip_handler() may also be
invalid.
This change makes both drm_output_start_repaint_loop() and
page_flip_handler() to schedule a full repaint in any of the
situations above.

Subject: [PATCH 5/7] compositor-drm: Add support for EGLDevice+EGLOutput
X-NVConfidentiality: public
As previously stated, EGLDevice and EGLOutput will provide means
to access native device objects and different portions of display
control hardware respectively.
Whenever EGL_EXT_device_drm extension is present, EGLDevice can
be used to enumerate and access DRM KMS devices, and EGLOutputLayer
to enumerate and access DRM KMS crtcs and planes.
By using EGLStreams and attaching an EGLOutputLayer consumer
(representing a DRM KMS crtc or plane) to it, compositor-drm can
produce final composition frames and present them on a DRM device.
This change adds required logic to support presentation through
EGLDevice+EGLOutput+EGLStream. Whether GBM or EGLDevice should be
used can be controlled by --use-egldevice backend argument.

Subject: [PATCH 6/7] simple-egl: Do not set EGL up until XDG setup is complete
X-NVConfidentiality: public
There is nothing that prohibits the underlying EGL_PLATFORM_WAYLAND
implementation to attach a buffer or commit surfaces right after the
Wayland EGLSurface has been created.
Since XDG Shell v6 imposes that no buffer attachments or surface commits
must be done before a configure is complete, Wayland clients shouldn't
start setting EGL up until XDG setup is complete.

Subject: [PATCH] compositor-drm: Release current & next fb when deactivating
the session
X-NVConfidentiality: public
With
commit 47224cc9312fef05c1a523ea0da0a1aae66f100d
Author: Daniel Stone <daniels@collabora.com>
Date: Sat Nov 5 08:04:07 2016 +0000
compositor-drm: Delete drm_backend_set_modes
we stopped forcing a modeset when restoring the session. The motivation
was that we would use a stale fb, so better to let the next repaint
handle it.
However, if drm_output::current != NULL, we won't issue a modeset upon
repaint.
This change releases both drm_output::current and drm_output::next when
deactivating the current session. This ensures the very first repaint
after restoring the session will issue a modeset.
