[why] When comparing current DSC timing settings with enforced through debugfs we have to calculate number of both vertical and horisontal slices. So instead of doing that every time we should just use number of slices rather than setting its dimensions. [how] In connector's dsc preferred settings structure change slice height and slice width parameters to number of slices vertical and horisontal. Also calculate number of slices in debugfs rather in create_stream_for_sink. Signed-off-by:

[why & how] Previously we were returning the number of bytes allocated for a write buffer from debugfs and when manually used it wouldn't rise any errors, but it wouldn't match the size of the parameters passed from userspace. In successful case return the size passed by usermode otherwise the error code is returned. That simplifies the parser helper and removes a potential error of returning mismatched input size.

[why] We need a virtual tool that would emulate a physical connector unplug to usermode, while connector is still physically plugged in. [how] Added a new option to debugfs entry "trigger_hotplug". It emulates hotplug irq handling scenario by clearing DC and DM connector states. It can be triggered with the following command: echo 0 > /sys/kernel/debug/dri/0/DP-X/trigger_hotplug Signed-off-by:

[why] For debug purposes we want not to enable DSC on certain connectors even if algorithm deesires to do so, instead it should enable DSC on other capable connectors or fail the atomic check. [how] Adding the third option to connector's debugfs entry dsc_clock_en. Accepted inputs: 0x0 - connector is using default DSC enablement policy 0x1 - force enable DSC on the connector, if it supports DSC 0x2 - force disable DSC on the connector, if DSC is supported Ex. # echo 0x2 > /sys/kernel/debug/dri/0/DP-1/dsc_clock_en Signed-off-by: -

[Why] DCValidator is created/destroyed repeatedly for cofunctional validation which causes a lot of memory thrashing, particularly when Driver Verifer is enabled. [How] Implement a basic caching algorithm that will cache DCValidator with a matching topology. When a match is found, the DCValidator can be reused. If there is no match, a new one will be created and inserted into the cache if there is space or an unreference entry can be evicted. Signed-off-by:
