drm_hwcomposer: Fix returned fence in PresentDisplay
DrmHwcTwo::HwcDisplay::PresentDisplay was always returning -1 as the
present fence. This commits ensures the fence fd is correctly retrieved
after doing the commit-frame operation. It also updates outdated logic
that caused PresentDisplay to return the retire fence rather than the
present fence.
DrmHwcTwo::HwcDisplay::AddFenceToPresentFence is also changed so that
it assumes it is given ownership of the file descriptor it receives as
argument. This function was indeed called consistently with this
behaviour, which meant the dup led to leakage of file descriptors.
With the changes above this patch fixes a failure in the CTS test
dEQP-VK.wsi.android.display_timing.fifo.display_timing (for example
running Android 10 on HiKey960). The test failed with the error
"Unexpectedly received invalid timestamp." reported multiple times in
the logcat output.

drm_hwcomposer: pre-filter modes provided to HWC2
Currently LocalDisplayAdapter in AOSP filters out similar modes based
on their currently limited supported attributes: width/height/refresh.
This leads to a situation where important modes are discarded, like the
preferred mode and/or the active mode, leading SurfaceFlinger to select
an unwanted and potentially invalid mode in the list provided by
drm-hwcomposer to HWC2.
Let's pre-filter the modes provided to HWC2 by :
- systematically adding the preferred mode
- systematically adding the current active mode, if different
from preferred mode
- keeping the interlaced modes filtering-out if no other non-interlace
modes with same widthXheight exists (for HD-Ready 1080i TVs or CVBS)
- discarding modes if a similar mode with same widthXheight@refresh was
already selected for HWC2
This mimics the behavior of LocalDisplayAdapter filtering algorithm,
but keeps the important modes from the DRM Point Of View and drops the
duplicate modes while keeping the mode ordering from DRM in account.
This local filtering should ultimately go out when HWC2 can actually
handle mode Attributes to describe Preferred mode, Interlaced, 3D...
and LocalDisplayAdapter uses these Attributes for filtering duplicate
modes.

we only see with certain dummy HDMI dongles (which provide

I'm still trying to understand more about why this happens

The net of the issue is we see CreateComposition() being called,
which adds the client_layer_ to the zmap. Then it creates the
DrmHwcLayers copying the non-initialized buffer_ value as the
sf_handle.
This then later causes a crash in ImportBuffer() when we

drm_hwcomposer: Fixup Sean's HiSi dummy planner
The dummy HiSi Planner is careful to not try to emplace layers
that aren't HW_FB. However, in some cases we might have a single
layer to draw. In that case the dummy importer will pretend it
imported the buffer, and the planner will skip over it and not
emplace it. Since there were no errors and the layers_ count is
the same as the available planes, we won't force client
composition, and will try to do device composition for the
buffer we didn't really import.
This results in the drm layer going a bit wonky.
Thus, this patch tries to fix this by erroring out if we try to
plan only a single layer, but don't emplace anything. This
results in the CreateComposition() function failing, which will
force client rendering, making it work (with only minimal logcat
noise - only in the single layer case).

drm_hwcomposer: add scene flattening
Flattening of a scene is triggered if it doesn't change for a while.
As of now there is a separate thread which triggers flattening if the
scene did not change in last 60 vsyncs.
There are two options for flattening a scene:
* Serial, by using a writeback connector attached to the same crtc as
the one driving the display. This happens only if possible_clones
mask reports that the display encoder and writeback encoder could
work simultaneously.
The steps for achieving this are:
1. Build a commit that enables writeback connector, we don't need to
build a commit that contains the entire active_composition, just
set the writeback specific properties a let the kernel duplicate
the rest of the state.
2. Commit and wait for writeback_fence to fire.
3. Setup a composition with just one plane enabled.
4. Apply the composition if a new one has not been applied meanwhile.
* Concurrent, by comitting the scene to a new unused crtc (state !=
DRM_MODE_CONNECTED) and getting the result back through a writeback
connector.
The steps for achieving this are:
1. Copy layers from active composition.
2. Plan layers of copy on the unused crtc. This is realized by using a
newly created DrmDisplayCompositor object.
3. Commit copy to the unsed crtc and get the result as a drmhwclayer.
4. Setup a composition with just one plane enabled. Re-importing the
buffers might be needed since we might have been using a different
dri node.
5. Apply the composition if a new one has not been applied while doing
the flattening

However, in the case where there is only one layer, such as with

avail_planes to one, and since there is only one layer, we don't

However, we don't know much about client layer, so information for

drm_hwcomposer: Try to fix clang-format pipeline
The clang-format pipeline generates false negatives
sometimes, with:
$ git diff -U0 --no-color master...HEAD | clang-format-diff-3.5 -p 1 -style=file > format-fixup.patch
fatal: ambiguous argument 'master...HEAD': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
as seen here:
https://gitlab.freedesktop.org/john.stultz/drm-hwcomposer/-/jobs/932
This tries to address the issue by explictly fetching
freedesktop/master and referencing FETHC_HEAD instead of master
which doesn't always exist.

drm_hwcomposer: Make sure we check for new 16bit alpha value
In commit
025d0a65 ("Use 16 bit value for plane alpha"),
the alpha value was bumped to a 16bit value.
Unfortunately in drmdisplaycompositor.cpp we are still
comparing it against a 8bit 0xff value, which now fails
causing the display to not start.
So fix this comparing to the 16bit 0xffff value.
With this change the display starts up again.

drm_hwcomposer: Fall back to client compositon if the gl precompostior fails
If the gl precompositor isn't being used, we cannot accept
every layer as a device composited layer.
Thus this patch adds some extra logic in the validate function
to fall back to client side compositing if the gl precompositor
did not initialize properly.
This does force everything to a single plane even if we have
a few available, but a deeper rework of the validate step
planning is needed before we can reliably make use of them.
Credit to Rob Herring, who's single plane patch was what this
was originally based on.

drm_hwcomposer: Cleanup gl precompositor init and provide uses_GL flag
The drm_hwcomposer has its own GL pre-compositor which is used
to squish layers when there are more layers then planes on the
display hardware. In many ways this duplicates the client-side
GL compositing that is done in SurfaceFlinger, but in theory can
be more highly optimized for the hardware.
Unfortunately, due to these optimizations, the drm_hwcomposer's
pre-compositor becomes somewhat hardware specific (originally
targeting nvidia hardware, I believe).
So on some hardware, the gl precompositor may not actually
initialize due to hardware missing features, or the hardware
supporting different shader APIs.
Rather then try to rework the drm_hwcomposers precompositor
to be more generic, I instead suggest that when the
precompositor fails to initialize, we simply fall back to the
already more widely compatible client compositor in
SurfaceFlinger.
Thus, this patch cleans up some of the precompositor
initialization, which didn't handle failures well.
