5978857615 overlay: 8994: De-prioritize DMA pipe in line mode
De-prioritize DMA pipes in line mode on 8994. If DMA pipes need to be
used in block mode for downscale, there could be cases where
consecutive rounds need separate modes, which cannot be supported
since we at least need 1 round in between where the DMA is unused

6c7eeac178 hwc: Extend partial frame update for split displays
Extends partial frame update support for split displays by calculating
changing region(ROI) independently for each half of the screen. In case of
only one half updating, display driver shuts down the DSI/MDP mixer control
of the non updating half.

Maintains two ROI's for each display. In case of Non-split
displays, only left ROI is updated.

For 8x26, if external display is connected, DMA pipe should never
be occupied by primary display. Otherwise, external display would
lack DMA pipe if switch to GPU composition.

a36be92d30 hwc/overlay: validate and prepare frame
Send the entire frame (array of overlays) to driver, so that it would
check pipes params and the whole frame wrt bandwidth and SMP.

Now, the overlay's commit API just prepares an overlay object but
makes no ioctl calls.

If the driver finds the frame, as a whole, to be not ok, the
validation fails and overlay/hwc return silently.

If a certain overlay object is mis-configured or pipes are
unavailable, the driver sets the number of objects it processed.
Overlay uses this to dump the incorrect config.

4b0a924ff4 overlay: pipe reservation mechanism for overlay
This change provides APIs for this mechanism. In a case where
pipeid corresponding to the layer needs to be reserved, then pipe
session could be initiated for that pipe. This will ensure that
the pipe is not garbage collected, and is manually destroyed when
the session (or pipe requirement) has been ended. This change
also provides the api to locally allocate the dest for the given
reserved overlay pipeid.

   denotes a Color layer.
2. There is no color member in HWC layer, so RGBA color value

6a9bb9ebd0 libhwcomposer: MDP partial frame update
This change adds support in HWC for MDP partial update applicable
only for command mode panels. Presence of MDP FB (GRAM) in
command mode panels allows MDP clients to update only the updating region
of the frame as rest of the frame will be cached in the GRAM.

HWC calculates the updating region of a frame (ROI) by deducing
outer bounds of its updating layer destinations. Layers not lying
within the calculated ROI will be dropped from the composition
since its illegal to program MDP pipes for non participating layers.

Saurabh Shah
3a23a9d09e overlay: Remove optimization that prevents garbage collection
There is an optimization to not do garbage collection (and thus UNSET)
if pipe usage hasn't change, added during older chip time frames.
It worked then because, continuous overlay failures were not normal,
and on failure userspace didn't UNSET remaining pipes.

On newer chips, owing to bandwidth limitations, continuous overlay
failures could happen, plus now we UNSET all other pipes. Thus each
round if GPU gets used, the optimization infers that pipe usage hasn't
changed and does not UNSET pipes.

Also the optimization doesn't do anything useful than saving a few
loops, but is suicidal in current situations, so can safely be done
away with.

784e98575f hwc/overlay: Force pipe config if list geometry changes
Force pipes of a display, whose geometry has changed, to pass
configuration arguments using MSMFB_SET_IOCTL. This helps the driver
make additive bandwidth calculations and reject the frame if the
requirements go beyond what the hardware can support.

This change still preserves the optmization to avoid ioctl calls, in
cases where pipe params are the same but makes an exception when
list geometry changes.

0ceeb6ad01 hwc/overlay: Introduce padding round between DMA modes.
Introduce a padding round between the DMA line and block modes.
Do this based on whether DMA is actually being used, when block mode

This relieves the driver of doing an UNSET ahead of vsync which could
cause blinks in all such transition scenarios.

This approach should lead to smooth transitions for multiple targets
with the exception of secure videos, where there could be a blink in
any of the different approaches we use.

e0dff93772 overlay: Reset allocation on all pipes, if commit fails.
If commit fails on a pipe, overlay hal needs to reset allocation
on all pipes for the given display. As MDP Comp fails, it falls
back to video and PipeBook logic does not pick-up those pipes on
which commit was successful. Driver sets new pipes and un-stages
previously set pipes (with same z-order). Pipe clean-up happens
and then in next round, PipeBook logic picks-up previous pipes
hence userspcae and driver remain out of sync.
