[Why] Uninitialized variable causes diag compilation build failure. [How] - Ensure that variable in question is always initialized before being used. - The variable in question is the USB4 DP training pattern. In case an unsupported training pattern has been requested, update status accordingly and abort current link training attempt. Reviewed-by:

[Why] For some customer blending transition cases, the available pipe for second stream is a pipe index that is greater than the number of timing generators, which can cause a problem in acquire_first_free_pipe since it assumes same index for pipe and timing generator [How] Added logic to use last timing generator index if the pipe index is greater than number of timing generators.

Recently we introduced a patch for fixing an MST issue, but it caused a regression on Club 3D since we could not set a refresh rate higher than 60Hz. This commit fixes this issue by adding a proper check after validating the stream. Fixes: f04d275d ("drm/amd/display: add mst port output bw check") Reviewed-by:

[Why] With ODM policy 2 to 1, there exists a new use case scenario where stream content is unchanged, but ODM may be used. When this happens, the stream needs to be committed with a new pipe setting. This did not happen due to stream change detection logic not accounting for ODM. [How] Set ODM flag in stream and commit stream when change in ODM has been detected due to policy change. Reviewed-by:

[Why] Unexpected change of aux hw mapping causes dmub soft hang when initiate aux transation at wrong aux channel. ddc_channel stands for hw dp aux index which is from vbios, but link_index is pure software concept for link count depending on which link is probed first. They are not interchangeable. dmub aux transaction could pass if happens eDP link_index gets the same value as vbios ddc_channel, e.g., ddc_channel = 1, link_index = 1 if they gets different, e.g., ddc_channel = 2, link_index = 0, overwrite ddc_channel with link_index will have wrong ddc channel being used for aux transaction in dmub PSR, cause aux transaction soft hang. [How] ddc_channel mapping to each link is determined by vbios and further parsed in dc. Such info. should not be touched in any kind, otherwise the mapping is screwed up leading to aux transaction timeout. Reviewed-by:

[Why] It's possible that we don't have a link encoder assignment if the context is NULL but we're calling dc_add_stream_to_ctx from DM directly. Link encoder assignment will happen later after global validation runs with fast_validate = false. [How] Remove the ASSERTION. We already guard against NULL link_enc. Reviewed-by:

[Why] While applying a state to hardware, there is a transition period where the back-end is reset using the old state; then enabled using the new state. Generally, the link encoder configuration module queries stream-to-encoder assignments in either the new or old state based on a mode variable. During the transition there is a need to query both states, however toggling this mode variable can lead to incorrect programming of encoders. [How] - Add new function to explicity query stream-to-encoder assignment in the current state rather than intermittently switch the mode of operation of the link encoder assignment module. - Add additional checks for encoder assignment defects. - Explicitly reset the mode of operation if application of state to hardware ends prematurely.

[WHY?] When adding/removing a plane to some configurations, unsupported pipe programming can occur when moving to a new plane. Such cases include pipe split on multi-display, with MPO, and/or ODM. [HOW?] Add a safe transistion state that minimizes pipe usage before programming new configuration. When adding a plane, the current state has the least pipes required so it is applied without splitting. This must be applied prior to updating the plane_state for seamless transition. When removing a plane, the new state has the least pieps required so it is applied without splitting. Signed-off-by:

[Why] Found when running igt@kms_atomic. Userspace attempts to do a TEST_COMMIT when 0 streams which calls dc_remove_stream_from_ctx. This in turn calls link_enc_unassign which ends up modifying stream->link = NULL directly, causing the global link_enc to be removed preventing further link activity and future link validation from passing. [How] We take care of link_enc unassignment at the start of link_enc_cfg_link_encs_assign so this call is no longer necessary. Fixes global state from being modified while unlocked. Signed-off-by:

[Why] Most of the time, a single display uses the ODM combine. When using multi-display, we use ODM combine only if it is necessary. These cases are not flexible enough for us, and we can improve them to take advantage of our hardware. We want to have more control over the ODM policy. [How] This commit add a new debug flag named enable_single_display_2to1_odm_policy to control the ODM policy and another flag named enable_dp_dig_pixel_rate_div_policy to fine control the ODM combine. This is possible by adding a new "pipe.dest" parameter that can be set to ODM 2:1 combined if we use a single display. For dynamic ODM combine, when using DP-DIG, DCN applies K2=2 settings for ODM combine. Note that this feature affects the following registers: - timing.pix_clk_100khz -> DP_VID_M, DP_VID_N - requested_pix_clk_100hz -> DP_DTOn_PHASE - OTGn_PIXEL_RATE_DIVK2 - DP_PIXEL_PER_CYCLE_PROCESSING_MODE - DIG_FIFO_OUTPUT_PIXEL_MODE - DP_VID_N_MUL Acked-by:

We don't need to validate and map root PD specially here, it would be validated and mapped by amdgpu_vm_validate_pt_bos if it is evicted. The special case is when turning a GFX VM to a compute VM, if vm_update_mode changed, we should make sure root PD gets mapped. So just map root PD after updating vm->update_funcs in amdgpu_vm_make_compute whether the vm_update_mode changed or not. v3: - Add some comments suggested by Christian. v2: - Don't rename vm_validate_pt_pd_bos and make it public.
