[why] For MST connector atomic check we have to check a new CRTC state instead of an old one, when checking if CRTC is disabled to release VCPI slots allocated. Signed-off-by:

[Why] Currently we share rxstatus between HDMI and DP, so we use 16bits The drm defines work with 1bytes at a time. So we need to split the HDMI rxstatus into 2bytes before we can use drm defines [How] -create rxstatus for dp and hdmi. rxstatus for hdmi is split into bytes using arrays. -use drm_hdcp defines for the remaining structs Signed-off-by:

[Why] drm already has this define [How] drm Mask is 0x08 vs 0x0800. The reason is because drm mask works on a byte. ^^ =======|| || Since the first byte is always zero we can ignore it and only check the second byte. Signed-off-by: -

[Why] These defines/macros exist already no need to redefine them [How] Use the defines/macros from drm_hdcp.h -we share the rxstatus between HDMI and DP (2 bytes), But upstream defines/macros for HDMI are for 1 byte. So we need to create a separate rxstatus for HDMI Signed-off-by:

[Why] The old way was to poll PSP and update the properties. But due to a limitation in the PSP interface this doesn't work for MST. [How] According to PSP if set_encryption return success, the link is encrypted and the only way it will not be is if we get a link loss(which we handle already). So this method should be good enough to report HDCP status. Signed-off-by:

[Why] Before we had a disable_type1 flag, this forced HDCP 2.2 to type0 There was no way to force type1. [How] Remove disable_type1 flag and instead add a flag to force type0/1. Signed-off-by:

[Why] We need to do this to support HDCP over MST Currently we save a display per link, in a MST case we need to save multiple displays per link. [How] We can create an array per link to cache the displays, but it complicates the design. Instead we can use the module to cache the displays. Now we will always add all the displays to the module, but we use the adjustment flag to disable hdcp on all of them before they are added. When we want to enable hdcp we just query the display(cache), remove it then add it back with different adjustments. Its the similar for disable. Signed-off-by:

[Why] HDCP 2.2 uses type0 and type1 content type. This is passed to the receiver to stream the proper content. For example, in a MST case if the main device is HDCP2.2 capable but the secondary device is only 1.4 capabale we can use Type0 Type0 content: use HDCP 1.4 or HDCP2.2 type0 Type1 content: Only use HDCP 2.2 type1 [How] We use the "hdcp content type" property in drm. We use the disable_type1 flag in hdcp module to select the type based on the properties. For updating the property we use the same logic as 1.4, but now we consider content_type as well and update the property if the requirements are met Signed-off-by:

[Why] HDCP 2.2 was disabled, we need to enable it [How] -Update display topology to support 2.2 -Unset hdcp2.disable in update_config -Change logic of event_update_property, now we set the property to be ENABLED for any level of encryption (2.2 or 1.4). Signed-off-by:

[Why] HDCP is a bit finicky so we try it 3 times, this leads to a case where if we fail the first time and pass the second time the error is still shown in dmesg for the first failed attempt. This leads to false positive errors. [How] Change the logging from ERROR to WARNING. Warnings are still shown in dmesg to know what went wrong. Signed-off-by:

[why] When updating DSC config, a new config has to be validated before proceeding with applying the update. Validation, however, modifies the current state. This means DSC config validation would affect pipe re-assignment, causing intermittent screen corruption issues when ODM is required for DSC. [how] - Use a copy of the current state for modified DSC config validation - Set the update type to FULL_UPDATE to correctly validate and set the actual state used for committing the streams Signed-off-by:

[Why] DCN will hang if we access registers before PHY init is done. So we need to spin or abort. [How] On hardware with DMCUB running and working we shouldn't time out waiting for this to finish and we shouldn't hit the spin cycle. If there's no hardware support then we should exit out of the function early assuming that PHY init was already done elsewhere. If we hit the timeout then there's likely a bug in firmware or software and we need to debug - add errors and asserts as appropriate. Signed-off-by:

[WHY] There can be a conflict between OS HDR multiplier and 3dlut HDR multiplier, which are both sent to DC. [HOW] Instead of having dc determine which HDR multiplier to use, make the decision in dm and send only the intended value in a surface update. Store the current OS HDR multiplier and determine whether to use it or the 3dlut's multiplier before sending the surface update to dc. Send multiplier to dc in fixed31_32 format, dc then converts it to hw format. Signed-off-by:
