display: edo panel: display quality optimization Because edo panel design using delta pixel design, so you can see aliasing in the display edges of the panel. In order to optimize the display quality,add algorithms to rending the framebuff data. If we detect the display pixel design is Delta, disable mdpcomp to get the whole single layer framebuff, then use the algorithms to optimize the pixel arrangement.

hwc: Avoid partial frame update on secure display 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.

display: Dynamic debug logging via binder 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.

hwc/overlay: Get rot dest dimensions instead of manipulating source 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. Change-Id: I501d998f2e0574683c764af9422742b2426ba0c7

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.
