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:

To improve the code readability, this commit removes a set of commented and not used functions for a long time. Notice that now we have the amdgpu_dm_dtn_log, which prints all the relevant information that we need. 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:

When PAGE_SIZE is larger than AMDGPU_PAGE_SIZE, the number of GPU TLB entries which need to update in amdgpu_map_buffer() should be multiplied by AMDGPU_GPU_PAGES_IN_CPU_PAGE (PAGE_SIZE / AMDGPU_PAGE_SIZE). Reviewed-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:

The user applications maybe register the KFD_EVENT_TYPE_HW_EXCEPTION and KFD_EVENT_TYPE_MEMORY events, driver could notify them when poison data consumed. Beside that, some applications maybe register SIGBUS signal hander. These applications will handle poison data by themselves, exit or re-create context to re-dispatch works. Signed-off-by:

Screen flickers rapidly when two 4K 60Hz monitors are in use. This issue doesn't happen when one monitor is 4K 60Hz (pixelclock 594MHz) and another one is 4K 30Hz (pixelclock 297MHz). The issue is gone after setting "power_dpm_force_performance_level" to "high". Following the indication, we found that the issue occurs when sclk is too low. So resolve the issue by disabling sclk switching when there are two monitors requires high pixelclock (> 297MHz). v2: - Only apply the fix to Oland. Signed-off-by:
