[Why] Once set ROI and do suspend/resume, current flow will not enable OTG_CRC_CTL again due to we'll defer crc configuration when stream is enabled. [How] Remove current suspend/resume function and have logic implemented into amdgpu_dm_atomic_commit_tail() Signed-off-by:

[why] The function's name doesn't represent what it actaully does. The function implements necessary steps for our hardware to transition from link training mode back to video idle mode. Therefore, rename the function as dp_transition_to_video_idle so everyone can understand it. Signed-off-by:

[Why] Active DP dongles return no EDID when dongle is connected, but VGA display is taken out. Current driver behavior does not remove the active display when this happens, and this is a gap between dongle DTP and dongle behavior. [How] For active DP dongles and non-DP scenario, disconnect sink on detection when no EDID is read due to timeout. Signed-off-by:

During the investigation on how to add visual confirmation on top of the planes used by DCN, it becomes evident that the lack of information in the code makes this work unnecessarily complicated. This commit introduces a set of documentation related to the RECOUT operation in order to make it easy for developers to navigate this set of functions. Signed-off-by:

Previous patch caused crash and had been reverted. This patch addresses the issue without regression. [Why] 1. Driver use umachannelnumber to calculate watermarks for stutter. In asymmetric memory config, the actual bandwidth is less than dual-channel. The bandwidth should be the same as single-channel. 2. We found single rank dimm need additional delay time for stutter. [How] Get information from each DIMM. Treat memory config as a single-channel for asymmetric memory in bandwidth calculating. Add additional delay time for single rank dimm. Signed-off-by:

v1: Use the current and custom pstate frequencies to track the current and user-set min/max values in manual and determinism mode. Previously, only actual_* value was used to track the currrent and user requested value. The value will get reassigned whenever user requests a new value with pp_od_clk_voltage node. Hence it will show incorrect values when user requests an invalid value or tries a partial request without committing the values. Separating out to custom and current variable fixes such issues. v2: Remove redundant if-else check Signed-off-by:

Mapping huge page, 2MB aligned address with 2MB size, uses PDE0 as PTE. If previously valid PDE0, PDE0.V=1 and PDE0.P=0 turns into PTE, this requires TLB flush, otherwise page table walker will not read updated PDE0. Change page table update mapping to return table_freed flag to indicate the previously valid PDE may have turned into a PTE if page table is freed. Signed-off-by:
