drm_hwcomposer: Fix sync_file fd leak from "Rework audofd"
In commit
0fade37afd60 ("drm_hwcomposer: Rework autofd"),
a change to some very subtle existing code caused a resource
leak such that after 10 minutes or so of active display
output, we would start seeing:
android.hardware.graphics.composer@2.3-service: failed to dup fence 10
over and over in logcat. Moving the mouse would cause black
frame to flicker and eventually Surfaceflinger would crash
and restart.
The problem was subtle change in the following hunk:
@@ -1047,10 +1049,9 @@ HWC2::Error DrmHwcTwo::HwcLayer::SetLayerBlendMode(int32_t mode) {
HWC2::Error DrmHwcTwo::HwcLayer::SetLayerBuffer(buffer_handle_t buffer,
int32_t acquire_fence) {
supported(__func__);
- UniqueFd uf(acquire_fence);
set_buffer(buffer);
- set_acquire_fence(uf.get());
+ acquire_fence_ = UniqueFd(fcntl(acquire_fence, F_DUPFD_CLOEXEC));
return HWC2::Error::None;
}
The core of the problem being, that the UniqueFd class calls
close(fd_) in its descructor. So while the change using
fcntl(...,F_DUPFD_CLOEXEC) matches what was burried in
set_acquire_fence(), dropping the creation (and more importantly
the destruction when it goes out of scope) of uf changes the
logic so we don't end up calling close on the aquire_fence fd
argument passed in.
One can confirm this resource leak by doing:
adb shell lsof | grep composer
And noticing the number of sync_file fds growing over time.
Thus, this patch fixes the logic, so instead of dup()'ing the
passed in fd, (and then closing it as done before Roman's
patch), we can just set aquire_fence_ to a new UniqueFd directly
using the aquire_fence fd passed in.
This pattern actually occured twice, so I've fixed it in both
places.

making analytical tracking of FD lifecycle much harder than it may be.
Keep this part clean is very important, since any wrong code may open
a hard-to-detect runtime bugs and fd leaks, which may accidentally slip
into the production.
Implementation:
1. Combine UniqueFd anf OutputFd into single class.
2. Reduce the API to be minimal and sufficient.
3. Document the API and use cases.
4. Move to utils/UniqueFd.h.

drm_hwcomposer: Tracking of the DRM FB objects using RAII
DRM framebuffer objects must be kept registered in DRM/KMS
while used for scanning-out (After atomic commit applied
for processing by display controller and until next atomic
commit is applied for processing).
Existing logic for tracking current state is overcomplicated and
needs to be redesigned. Also further developing of drm_hwc will
require migration to asynchronous atomic commit, so additional
asynchronous FB cleanup logic must be created.
Buffer caching logic will also benefit from this.
With the RAII all further changes will be less painful and more robust.
By this commit I also renamed DrmGenericImporter to DrmFbImporter:
'Fb' word is present in most of existing composers (android and linux)
so it will be easier to compare different implementations.

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.
With this patch, things are back to working on both hikey960

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: Implement *DisplayBrightness* stubs
Implement *DisplayBrightness* stub to be able boot
Android 11 using android.hardware.graphics.composer@2.3-service.
This change caused by error during boot:
failed to get hwcomposer2 function 61
61 is equal to SetDisplayBrightness.
GetDisplayBrightnessSupport is a companion of it.

drm_hwcomposer: Fix ValidateDisplay() when lowest z-order is nonzero
ValidateDisplay()'s algorithm for achieving minimal GPU load assumes
that the lowest z-order is zero and that layers have sequential z-orders.
CalcPixOps() and MarkValidated() are also written with the same assumption.
However, there is no such guarantee provided by SurfaceFlinger and VTS
tests like PRESENT_DISPLAY_NO_LAYER_STATE_CHANGES fail as they only have
one layer with z-order of 10.
Normalise the mapping between layers and z-order so that the algorithm works
as intended.

drm_hwcomposer: Run test commit only when it actually needed
Composition testing is expensive. We do not need to spend CPU time when:
* All layers are marked as a client.
The patch skips CommitFrame function called by the ValidateDisplay
method in this case.

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
// setLayerBuffer() was ignored.
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.
Not sure how we could reproduce the same sequence of calls on
another Android version.

Crosvm doesn't implement EDID virtio cmd, so when commit

- Don't negate errno before passing to strerror, at least on
bionic this results in "Unknown error -x" instead of the actual

drm_hwcomposer: Add fallback to client for layers flattening
Google recommends to delegate composition to GLES instead of HWC when
screen isn't updating to conserve power, as stated on page
https://source.android.com/devices/graphics/implement-hwc.
Current implementation of hwcomposer has flattening of layers if after
some time there were no updates of frames, but it uses writeback
connector. Not every device has a support of writeback feature, so
some sort of fallback should be provided.
It is possible to fallback to client composition in case if writeback
isn't available. This is used to reduce power consumption since
squashing layers into a single layer on GPU and then using that buffer
is more efficient than loading drm device.
