drm_hwcomposer: Fix drmSetMaster() usage
After commit
3b24cd911ebf ("drm_hwcomposer: Ensure composer has
master access to DRM/KMS") was merged I started seeing failures
on 5.4 based kernels.
Diggin into it, it seemed on those kernels drmSetMaster() was
always returning -EACCES, due to the following upstream kernel
change not being present:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=
45bc3d26c95a8fc63a7d8668ca9e57ef0883351c
That change landed around 5.6, so for older kernels we need to
make sure older kernels without this patch still work. So this
patch, as suggested by Roman Stratiienko, reworks the logic
so we call drmSetMaster() and then check drmIsMaster(), rather
then failing due to the return value.

drm_hwcomposer: refactor platform directory
Motivation:
Platform term meaning used in drm_hwcomposer does not correspond to the
content of the platform directory. Platform directory consists of:
1. Buffer information getters for different gralloc (currently called platform).
2. Composition planner logic (which has flaws and should be reworked into
layer->plane mapping during validation stage logic).
3. DrmGenericImpoter with reference counting logic.
Android-11 IMapper@4 metadata API offers a generic way to access buffer
information which makes other gralloc buffer information getters obsolete.
Legacy getters should be maintained for some time until all known users
will migrate to Mapper@4 API.
Implementation:
1. Split 'PlatformImporter' logic to 'Importer' only and 'Buffer Getter' logic.
a. Remove buffer_handle_t parameter from ImportBuffer(). Instead user should
get BufferInfo using ConvertBoInfo to struct hwc_drm_bo_t, then use it for
ImportBuffer().
b. Move DrmGenericImporter.{cpp/h} into the drm directory.
2. Isolate planner code in single file and move it to compositor directory as
compositor/Planner.{cpp/h}
3. Rename platform definition
a. Rename platform directory to bufferinfo.
b. Rename/move bufferinfo/platorm*.{cpp,h} getters to
bufferinfo/legacy/BufferInfo*.{cpp,h}. Align class names/includes.
4. Split legacy/metadata getters logic.
a. Apply existing bufferinfogetter base class only for legacy getters.
b. Combine legacy/generic gettera under new base class.
c. Create a placeholder for generic(metadata) getter.

drm_hwcomposer: fix incorrect layer_count usage
According to [1] DRM YCrCb planes is not the same as gralloc layers.
DRMHWC2 has no information about number of layers used in the buffer.
Also supplying value other than 1 will allways fail validation on
passthrough MapperHal@2.1 and probably other passthrough implementations [2].

drm_hwcomposer: Fix invalid buffer_handle_t pointer
In Android 11, at boot time, I see the following sequence of
calls from SurfaceFlinger that trigger this:
// Composition type for layer is saved in DRM HWC Layer validated_type_
validateDisplay()
// Layer composition type saved in DRM HWC Layer sf_type_
acceptDisplayChanges()
// Composition type in Layer sf_type_ is now "client" so DRM HWC doesn't
// update the Layer buffer pointer
setLayerBuffer()
// DRM HWC Layer sf_type_ is now changed back to "device"
setLayerCompositionType()
// DRM HWC iterates through the layers and finds that Layer composition
// type in sf_type_ is "device" so thinks it is fine to calls
// importBuffer() but this Layer now has an invalid pointer as the

validateDisplay()
Thus this patch, changes the logic to always update the
buffer_handle_t pointer in setLayerBuffer regardless of
composition type rather than keeping the invalid buffer_handle_t
in the Layer obect. The composition type may be changed back to
device composition by setLayerCompositionType at which point the
Layer object needs to have saved the buffer_handle_t.

I'm trying to utilize a policy of lighter reviews w/ quick reverts
when there are issues to keep things moving. So with that in mind
I'm reverting "Extract more BO data by Imagination importer" since
its breaking the build in AOSP.
See:

https://android-review.googlesource.com/c/platform/external/drm_hwcomposer/+/

This breakage is due to the importer code being tightly tied to
the gralloc private handle definitions, which is a common problem
as the gralloc and drm_hwcomposers are separately maintained.
The beagle_x15 gralloc is apparently older, and doesn't have
the newly utilized fields.
So for now, revert this to stay in sync w/ AOSP. I'm happy to
re-apply as soon as a fix is in place which adds some sort of
versioning checks so hopefully drm_hwc can work with different
versions of the gralloc code.
Once users of the old gralloc code are updated, we can remove
such version checks if needed.

each layer.
In some future we should apply some average gains depending of operation type
to calculate pixops more precisely. (e.g. scaling should take more pixops than
blending, and blending should take more that copying, etc.).
Using pixops could be very helpful when drm_hwc HAL have a choice which layer
sets to merge by GPU, making possible minimal energy model based planning.
Create statistics of the following events:
1. Total frames count
2. Total pixel operations
3. Pixel operations validated to use GPU (CLIENT)
4. Calculate composer efficiency: DEVICE/TOTAL operations ratio
5. Failed atomic validation commits count
6. Failed atomic presenting commits count
Usage:
- $ adb shell dumpsys SurfaceFlinger
Statistics will be shown at the end of the dump in 2 forms:
1. Since system launched
2. Since last dumpsys command called
Using statistics for the regression slope monitoring example:
1. Boot the board without the change
2. Use touch or keyboard (avoid using of mouse pointer) to do some predefined
actions (open application, start video, etc.)
3. Save the metrics
4. Boot the board with the change
5. Do exactly the same actions as in (2)
6. Save the metrics
7. Use metrics before and after change to indicate regression slope

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.

In such composition SF will merge layers 0 and 3 and hwcomposer will

Reproduces with compositions that requires 'cursor' or 'dim' layers.
How to reproduce:
1. Connect USB mouse when on home screen, you should see mouse cursor
under icons (Tested with Launcher3QuickStep desktop)
2. Go to Settings -> WIFI -> Connect to the AP, then you should see

Solution:
1. Mark intermediate layers as CLIENT to ensure CLIENT section is in range
from bottom layer to most top CLIENT layer.
2. Use this layer composition to validate if DRM can handle it.

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.
