[Why and How] - For driver disable cases in current implementation, if P-State is unsupported or still supported by firmware, we force it supported by DCN. - SubVP now needs to be included in this case along with FPO. Reviewed-by:

[Why & How] ODM seamless transitions require DIV_MODE_AUTO. However, DIV_MODE_AUTO only works when all the horizontal timing params are divisible by the ODM combine factor. Therefore, disable the ODM 2:1 policy when the horizontal timing params are not divisible by 2. Reviewed-by:

[why] When user unplugs mst hubs, the current code will forcefully zero entire mst payload allocation table structure stored in link before we deallocate actual payload when disabling stream. During the first disable stream sequence, we will use current mst payload allocation table to determine if link should be turned off. Because we zero out it before we are disabling stream, the payload allocation table stored in link doesn't represent the actual allocation status, so we turn off link at the first disable stream without waiting until all streams' payloads have been deallocated. This avoilates the designed deallocation sequence and caused system hang in DP2 scenario. [how] Remove payload during deallocation and never zero payload allocation structure without actually deallocating payload. Reviewed-by:

[why] Original change 594b237b ("drm/amd/display: Add interface to track PHY state") was implemented by assuming stream's dpms off is equivalent to PHY power off. This assumption doesn't hold in following situations: 1. MST multiple stream scenario, where multiple streams are sharing the same PHY output. Toggle dpms off for one of the stream doesn't power off the PHY due to the presence of other streams. 2. enable stream failure scenario, where enable stream fails due to failure of link training. This will cause DPMS off is set to false, while the actual PHY power state is off in certain cases. Due to the problematic assumption, the logic will skip disabling other streams for MST multiple stream scenario, therefore PHY is not actually powered off. [how] 1. Rework this refactor by moving PHY state update down to hardware level, where we update PHY state in place when hardware sequencer is actually changing the power state of the PHY hardware. 2. Reimplement symclk on TX off workaround in place when we are actually calling transmitter control to power off PHY in dcn32. Note the workaround is added due to the lack of proper software interface to set TX while keeping symclk on. We plan to address this interface problem so we can set TX off only without affecting symclk in future dcn versions. Fixes: 594b237b ("drm/amd/display: Add interface to track PHY state") Reviewed-by:

[Why] DC makes use of layer_index (zpos) when picking the HW plane to enable HW cursor on. However, some compositors will not attach zpos information to each DRM plane. Consequently, in amdgpu, we default layer_index to 0 and do not update it. This causes said DC logic to enable HW cursor on all planes of the same layer_index, which manifests as a double cursor issue if one of the planes is scaled (and hence scaling the cursor as well). [How] Use DRM core helpers to calculate a normalized_zpos value for each drm_plane_state under each crtc, within the atomic state. This helper will first consider existing zpos values, and if identical/unset, fallback to plane ID ordering. The normalized_zpos is then passed to dc_plane_info during atomic check for later use by the cursor logic. Reviewed-by:

[Why] 420 modes are limited by FMT buffer width of 4096 which requires multi-pipe support in form of ODM combine. If 420 modes have greater HActive than 4096, the DML logic should accomodate whether it should be rejected, or ODM combine 2:1 or 4:1 is triggered accordingly. [How] FMT Buffer limit of 4096 in DCN32. Force ODM combine depending on HActive and FMT Buffer limit. Reject modes if TMDS 420 and above 4096. Acked-by:

This patch updates the PTE flags when translate further (TF) is enabled: - With translate_further enabled, invalid PTEs can be 0. Reading consecutive invalid PTEs as 0 is considered a fault. To prevent this, ensure invalid PTEs have at least 1 bit set. - The current invalid PTE flags settings to translate a retry fault into a no-retry fault, doesn't work with TF enabled. As a result, update invalid PTE flags settings which works for both TF enabled and disabled case. Fixes: 352e683b ("drm/amdgpu: Enable translate_further to extend UTCL2 reach") Reviewed-by:
