7d79378895 kmssink: Add "restore-crtc" property
This adds "restore-crtc" property using which one
can restore previous crtc mode.

By default it is enabled, if CRTC was already
active with a valid mode and kmssink set a new mode
on CRTC using force-modesetting.

This helps user restore previous crtc mode and get
the previous session back after running a kmssink
pipeline involving a force-modesetting.

For e.g. When running a kmssink pipeline on rpi
using force-modesetting on tty console, it was giving
a blank screen after pipeline, and now with help of restore-crtc
functionality, CRTC is set with previous crtc mode
previously active on tty console.

2f30287b5f kmssink: Escape DRM property names
This allow setting properties that contains spaces. The spaces are
replaced with '-'. As an example, one can set the connector proper
"scaling mode" with the following:

Can be used to pass custom connector properties to DRM. Properties can

with the following gst-launch-1.0 syntax. Note that the name of the
structure is ignored.

62a194c781 kmssink: configure mode setting from video info
drmModeGetFB returns -EINVAL for multi-planar framebuffers. Instead of
depending on the framebuffer dimensions to select the mode, use width
and height from GstVideoInfo, which was used to create the framebuffer
in the first place.  This enables kmssink to display multi-planar
formats such as I420 or NV12 with modesetting enabled.

9a34dd8c2a kmssink: Add support for mxsfb-drm driver
The mxsfb-drm driver has been added to the kernel long ago and will now
be the default display driver for NXP i.MX28, i.MX6SX and i.MX7D
processors so now is a good time to add it to kmssink.

Also, this is used in the upcoming i.MX8MQ and i.MX8MM processors.

DRM_RDWR was not defined until libdrm 2.4.68.  However,

Seems silly to to bump minimum libdrm version for a simple

7e38fb5422 kms: fix crash if bo allocation failed when copying to dumb buffer
If bo allocation failed we destroy the buffer and return GST_FLOW_ERROR,
but the @buffer pointer was still pointing to the address of the
destroyed buffer. gst_kms_sink_copy_to_dumb_buffer() was then trying to
unref it when bailing out causing a crash.

Leave @buffer untouched if allocation failed to fix the crash.
Also remove the check on *buffer being not NULL as gst_buffer_new()
will abort if it failed.

b8c5a4c9ed kmssink: drop last rendered buffer on ALLOCATION and DRAIN queries
kmssink keeps a reference on the last rendered buffer. If this buffer
refers to an upstream buffer, it should be should be released on DRAIN

pool if needed. As the buffer may be used for scanout, we copy this
buffer into a dumb buffer prior to let it go.
