[Why] Some LED panel drivers might not like fractional PWM. In such cases, backlight flickering may be observed. [How] Add a DC feature mask to disable fractional PWM, and associate it with the preexisting dc_config flag. The flag is only plumbed through the dmcu firmware, so plumb it through the driver path as well. To disable, add the following to the linux cmdline: amdgpu.dcfeaturemask=0x4 Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=204957Signed-off-by:

Ras reboot debugfs node allows user one easy control to avoid gpu recovery hang problem and directly reboot system per card basis, after ras uncorrectable error happens. However, it is one common entry, which should get rid of ras_ctrl node and remove ip dependence when inputting by user. So add one new auto_reboot node in ras debugfs dir to achieve this. v2: in commit mssage, add justification why ras reboot debugfs node is needed. v3: use debugfs_create_bool to create debugfs file for boolean value Signed-off-by:

If device reset/suspend/resume failed for some reason, dqm lock is hold forever and this causes deadlock. Below is a kernel backtrace when application open kfd after suspend/resume failed. Instead of holding dqm lock in pre_reset and releasing dqm lock in post_reset, add dqm->sched_running flag which is modified in dqm->ops.start and dqm->ops.stop. The flag doesn't need lock protection because write/read are all inside dqm lock. For HWS case, map_queues_cpsch and unmap_queues_cpsch checks sched_running flag before sending the updated runlist. v2: For no-HWS case, when device is stopped, don't call load/destroy_mqd for eviction, restore and create queue, and avoid debugfs dump hdqs.

This is a quick and low risk fix. Those APIs which are exposed to other IPs or to support sysfs/hwmon interfaces or DAL will have lock protection.

[Why] * Clk Mgr DTO update point did not cover all needed updates, as it included a check for plane_state which does not exist yet when the updater is called on driver startup * This resulted in another update path in the pipe programming sequence, based on a dppclk update flag * However, this alternate path allowed for stray DTO updates, some of which would occur in the wrong order during dppclk lowering and cause underflow [How] * Remove plane_state check and use of plane_res.dpp->inst, getting rid of sequence dependencies (this results in extra dto programming for unused pipes but that doesn't cause issues and is a small cost) * Allow DTOs to be updated even if global clock is equal, to account for edge case exposed by diags tests * Remove update_dpp_dto call in pipe programming sequence (leave update to dppclk_control there, as that update is necessary and shouldn't occur in clk mgr) * Remove call to optimize_bandwidth when committing state, as it is not needed and resulted in sporadic underflows even with other fixes in place Signed-off-by:

[Why&How] BT.2390 EETF is used for tone mapping/range reduction. Say display is 0.1 - 500 nits. The problematic case is when content is 0-400. We apply EETF because 0<0.1 so we need to reduce the range by 0.1. In the commit, we ignore the bottom range. Most displays map 0 to min and then have a ramp to 0.1, so sending 0.1 is actually >0.1. Furthermode, HW that uses 3D LUT also assumes min=0. Signed-off-by:

[why] A display that supports DRR can never really be considered "synchronized" with any other display because we can dynamically enable DRR (i.e. without modeset). this will cause their relative CRTC positions to drift and lose sync. this will disrupt features such as MCLK switching that assume and depend on their permanent alignment (that can only change with modeset) [how] check for ignore_msa in stream when considered synchronizability this ignore_msa is basically actually implemented as "supports drr" Signed-off-by:
