671d9fed3a kmssink: Do not source using padded width/height
The width/height from the video meta can be padded width, height. But when
sourcing from padded buffer, we only want to use the valid pixels. This
rectangle is from the crop meta, orther it is deduces from the caps. The width
and height from the caps is save in the parent class, use these instead of the
GstVideoInfo when settting the src rectangle.

This fixes an issue with 1080p video displaying repeated or green at the
padded bottom 8 lines (seen with v4l2codecs).

040077dbc8 kmssink: fix memory leak on failing allowed caps
When drm does not find any format, the allowed_caps is
empty one and need to be unref by the caller.

63940feaaf kmssink: Save last metadata at the same time as the last buffer
The render width/height and the vinfo was only saved upon renegotiation. This
fixes the problem by saving this metadata at the same time the buffer is
saved. The saved copy of this is needed for expose() and drain() virtual functions.
This fixes various assertion that happens on drain query.

115b65d1ab kmssink: Fix crash with force-modesetting=1
This is a master regression, we would allocate a bo without having
created the allocator yet. As of now, we lazily create the allocator.

80b599c81b kmssink: Do not drain if imported buffer are from KMS
This adds a check to avoid draining when the imported buffers are in
fact own by kmssink. This happens since we export our kms buffer as
DMABuf. They are not really imported back as we pre-fill the cache,
but uses the same format as if they were external. This fixes
performance issues seen with videocrop2-test (found in -good).

8574154cc8 kmssink: Avoid drain on caps changes
Draining systematically on caps changes was a hack. Instead, properly
save the render information used to render last_render, and use that
information to drain. This fixes performance issues met with video crop
meta and per frame caps changes.

112baf404e kmssink: Fixup all errno tracing
All DRM ioctl uses errno to report the error and simply returns -1
when some error occured. This patch fixes all usage of the return
value instead of errno to trace the error type and moves to g_strerror
instead of string.h strerror in order to be consistent with the rest
of GStreamer.

cbff147f71 kmssink: fix tmp_kmsmem leaks

showing a frame or if none is showed this memory was leaked.

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.

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.

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
and ALLOCATION queries so all upstream buffers can be returned to the
pool if needed. As the buffer may be used for scanout, we copy this
buffer into a dumb buffer prior to let it go.
