The bitmap in cu_info structure is defined as a 4x4 size array. In Acturus, this matrix is initialized as a 4x2. Based on the 8 shaders. In the gpu cache filling initialization, the access to the bitmap matrix was done as an 8x1 instead of 4x2. Causing an out of bounds memory access error. Due to this, the number of GPU cache entries was inconsistent. Signed-off-by:

Problem: When run_job fails and HW fence returned is NULL we still signal the s_fence to avoid hangs but the user has no way of knowing if the actual HW job was ran and finished. Fix: Allow .run_job implementations to return ERR_PTR in the fence pointer returned and then set this error for s_fence->finished fence so whoever wait on this fence can inspect the signaled fence for an error.

[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.

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.
