For split displays, earlier we allowed pipes to switch mixers in
subsequent rounds. This change prevents that and makes sure there
is one composition round where a pipe being transferred to another
mixer of the same display is UNSET

If framebuffer needs to be configured, configure it before all the
other layers in mdp composition. This helps in cases where we are
out of SMPs and framebuffer configuration fails owing to that.
Framebuffer being the fallback path, should always get highest
priority when reserving SMP blocks

Dumpsys runs in different thread not in composition thread.
Accessing mdp composition frame info in dumpsys with out
synchronizing could cause crash since frame info can get reset
in composition thread.

Add support for unevenly split primary displays.
The driver provides info about the split via msm_fb_split sysfs node
For external we assume even split. If driver doesn't specify any split
for primary, we default to even split.

This change adds adb property support to disable mixed mode in
MDP Comp. Will be helpful in debugging issues to narrow down the
root cause.

- 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.

Reset idle fall back at the end of prepare, so that irrespective of
whether primary or external is configured first, both will fall back.

There is h/w limitation when MDP_OP_SCALE_RGB_ENHANCED bit and
MDP4_OP_SCALEX_EN or MDP_OP_SCALEY_EN bit is set.
The minimum block size is 2x2. MDP will hang if the source RGB image
height or width is equal to 1. Hence fallback to GPU in such cases.

Fix reseting on handles, they never were in most cases,
owing to wrong size.
Fix redrawing, which needs to be done also when the fb's zorder changes.
Fix mdpcount update which should happen before we assess the pipes
available versus the pipes needed.
Handle video only cases, where other UI layers could be present, but we
cannot use MDP comp for them.
Restructure MDP comp decision model and some redesign.

With this change we are moving MDP composition from all-or-nothing
implementation to mixed mode implementation where layers can
partially be composited through MDP and while rest of the layers are
composed / cached in framebuffer.
- Mixed mode design is based on layer caching
- Mixed mode path is configured only when non-bypassing
layers are cached.
- Never allow mixed mode when FB needs to be udpated.
- If we cannot bypass all MDP comp marked layers, bail
out completely.

This change adds support to MDP composition to use DMA pipes when
layer scaling is not needed. Also makes sure not to invoke
MDP rotator when DMA pipes are configured since MDP rotator will
expect both the DMA pipes to available for performing rotation.
In such cases, we let the first frame of rotated video frame to
fall back to FB.

-Add support for Video via overlay on 4k2k external panel.
-Add support for rotating videos on 4k2k panels. We use
pre-rotation in hwc to rotate a video into a single buffer,
irrespective of panel size. Then this buffer is fed to MDP.
Rotator objects are managed by the new RotMgr.
-Cleaup mdpcomp and overlay.

This patch:
-Implements MDP composition for higher resolution

-Adds DMA pipe support for high res. MDP composition

This is a software workaround for MDP hardware limitation where
DSI mode panels wont give more than 30 FPS if buffers in RGB
pipes are of width less than 5
MDP can't handle layers of width less than 3. Fail MDP
Composition for those frames.

Does a basic implementation of the dump function
called by SurfaceFlinger in dumpsys.
Further logs in different areas can be added later on

This change extends MDP composition to support
upto 4 layers by making border fill as base pipe and
using all MDP h/w pipes in overlay mode.

SurfaceFlinger re-creates HWC worklist only for new frame and on layer geometry
change. Invalidate triggered by idle timeout refreshes the existing worklist
retaining its previous composition type. So its MDP comp's responsibility to
clear layer composition types to HWC_FRAMEBUFFER on timeout.
