- The primary panels refresh rate can be change by clients
- Required refresh rate will be set by client using metadata
- If there are multiple clients requesting, it will be used only
when the refresh rates are equal, else it resets to default
- Set the new refresh rate only when there are only YUV layers
updating or when the list has only one RGB layer updating
- MdpVersion gets the dyn fps capabilities from panelInfo

1. Fall back to video only composition instead of full GPU composition
to release all pipes assigned to RGB layers for primary display
during external configuration and padding round. Do this only for
the target which has total number of pipes >= 8.
2. This resolves blinks when HDMI is connected during secure video
playback usecase.

If two PTOR layers are overlapping, remove overlapping

In secure RGB usecase, we mark secure RGB layers for MDP composition
as GPU does not support secure RGB composition even if skip layer
is present. In markLayerForCaching function, when we encounter a skip
layer marked for MDP composition whose handle can be null will flag
"Layer handle is NULL" as error. So we can enable this message only
when MDP debugging logs are enabled.

1. Detect and account the number of secure RGB layers present.
2. Mark secure RGB layers for MDP comp in cache based stratergy.
3. If full MDP comp and partial MDP comp fails, Mark secure RGB
layers for MDP composition.
4. In partial MDP comp reject load based composition, if secure
layer is present to avoid GPU composition.
5. Disable idlefallback feature if secure RGB layer is present
to avoid GPU composition.

Source split splits the crop and position into half, but if the
widths are odd and the left, right crops are swapped for H-flip, it
induces a scaling that is unaccounted for while allocating pipes.
This could lead to DMA pipes having scaling.
To fix this, the patch manipulates position width, if a swap happens.

Remove support for overriding a layer's z to set it up for foreground.

Add support for rotator downscale. This is enabled from 8994 onwards
Constraints:
--Downscale should be a power of 2, max upto 32
--Both directions should have equal downscale
--{src_w, src_h} mod downscale = 0
--No BWC
--No Interlaced video support
The rotator's destination rect is modified to reflect the presence of
downscale. Any downscale calcs should be done only after adjusting
crop to meet rotator's requirements.
Smaller downscale is used if we need to chop off any more than 1
line or pixel.

* Limit the number of rotator sessions to 4 both in

Since there is no content underneath a PTOR layer, all overlapped
contents have been composed by Copybit on render buffer. So for a
PTOR layer, we can set blending to HWC_BLENDING_NONE and planeAlpha
to 0xFF. And the transform for the PTOR layer should be set to 0 to
avoid MDP flipping again.

1. For PTOR layers, MDP needs to be configured with width, height
and format of the Copybit render buffer, otherwise it will lead to
artifacts due to incorrect render buffer reads, when PTOR layer
handles have un-equal strides.
2. Remove render buffer offset for a PTOR layer and configure MDP
with modified source crop, based on its position on render buffer.
3. A layer cannot qualify for PTOR feature, if none of below layers
intersect with it.

Read the maximum width mixer can output from drivers
and consider this in identifying if dual pipes are required
to support a layer. So far above 2K dimensions we are using dual
pipes, but 8x39 mixer output can be upto 2560. So there is no
need of dual pipes as long as pipe data is less than this limit.
Compare layer/panel resolutions against this limit to deduce
if there is a need for dual pipes or split.

On configuring for secure display, MDP switches to secured
memory bank. Invoking any more DCS panel commands which
follows non-secure path will cause XPU violation. So its
necessary for HWC to turn off partial update to avoid DCS
commands due to ROI change.

Provides a way to enable/disable logs at runtime via binder.
The logs need to be enabled from a priviliged shell.
For example,
$ adb shell service call display.qservice 15 i32 0 i32 1
Here 15 is the integer code for DYNAMIC_DEBUG in IQService.h
The first parameter 0 is for DEBUG_ALL
The second parameter 1 is to enable.
Hence, this command enables all debug logs.
Another example - this command enables vsync logging
$ adb shell service call display.qservice 15 i32 2 i32 1

Currently for Mdss rotator we manipulate the layer buffer dimensions
to be equal to what rotator's destination dimensions would be, so that
these could be fed to MDP. Instead, this patch introduces APIs in
rotator so that hwc can directly query destination crop, width, height,
format from rotator.
This also simplifies the updateSource() and configRotator() helpers.

- Consider two smallest layers for PTOR feature which uses MDP comp.
- These two layers are rendered on a buffer and are queued to MDP
to acheive full MDP Composition
- This helps to acheive performance enhancement

1) While setting BWC check for 90 transform and swap crop
2) Calculate decimation in the getDecimationFactor API itself.
Currently, a residual downscale is calculated and the clients have
to take logs and apply forcible decimation like in MdpCtrl
3) Fix bug where transform gets typecasted to bool

Source Split layers always if the driver indicates so by setting
the src_split_always in the capabilities sysfs node.
This is applicable to layers whose width > mixer's width, since
MDP clk rate is dependent on max(mixer_width, layer_width).
This feature can be enabled if the panel height is more than a
certain empirically derived value. Splitting always in those
cases can help with a lower voltage.

MDP bandwidth limitations can be avoided, if the overlapping region
covered by the smallest layer at a higher z-order, can be composed
on a render buffer using Copybit, and then it can be queued to MDP
along with other layers. It helps to improve performace by avoiding
GPU Composition in use cases like Home Screen pan. To enable this
feature, set system prop "persist.hwc.ptor.enable" to "true" or '1'
and enable Copybit HAL compilation.
