hwcomposer: Fix regression in hwc_sync
Hwc_sync is in the hotpath of display
rendering and gets called every ~17ms
during active rerendering.
Reading the property "debug.egl.swapinterval"
on every execution of hwc_sync causes a major
regression where the execution of hwc_sync
is much slower than it can be.
Doing I/O in hotpaths is inacceptable
and can cause an unnecessary constant
I/O load, additionally to the slowdown
in display rendering which was caused
in this case.
As solution, we condition this debugging
feature with "DISPLAY_DEBUG_SWAPINTERVAL",
so it can be enabled when explicitly needed.
Gralloc is not directly affected by the regression,
it was adjusted to match the conditioning
of the swapinterval debugging feature.
The HALs of msm8084,msm8226,msm8909,msm8960 and
msm8994 are affected by the regression and
get patched by this patch. Newer HALs
are not affected.
The stats contained in this patch were
collected using a Nextbit Robin (MSM8992),
which uses the msm8994 HAL.
Test: Manual testing for proper conditioning.
Test: Running full CTS suite without DISPLAY_DEBUG_SWAPINTERVAL set.

hwc: Fix to avoid heap corruption
- Check for MAX_NUM_APP_LAYERS before updating yuv indices array.
- Fall back to GPU composition when number of app layers exceeds
MAX_NUM_APP_LAYERS to avoid heap corruption.

hwc: msm8960: Add padding round for transitioning VG pipe
When an external display is connected, the primary display may be
using up both VG pipes. However, a VG pipe is necessary for
playing secure video on the external display. This needs a
padding round to transition the pipe to the external display's
mixer.

hwc: Enable rotator during resolution change.
MDP VG pipe framesize register is not double bufferred.
It introduces corrupted frame during resolution change especially when
rotator is not used. Enable rotator to handle the transition case.

hwc: Fix rotator size allocation to max buffer size
When using the metadata for calculating the rotator destination
buffer size, the allocation happens frequently in the smooth
streaming use case leading to fragmentation of rotator memory.
Base the calculation of this buffer size on the actual width and
height of the buffer instead of the metadata.
