With previous golden settings, compute task can't use reserved LDS (32K) on CU0 and CU1. On 64K LDS system, if compute work group allocate more than 32K LDS, then it can't be dispatched to CU0 and CU1 because of the reservation. This enables compute task to use reserved LDS on CU0 and CU1. Signed-off-by:

At default, the autosuspend delay of audio controller is 3S. If the gpu reset is triggered within 3S(after audio controller idle), the audio controller may be unable into suspended state. Then the sudden gpu reset will cause some audio errors. The change here is targeted to resolve this. However if the audio controller is in use when the gpu reset triggered, this change may be still not enough to put the audio controller into suspend state. Under this case, the gpu reset will still proceed but there will be a warning message printed("failed to suspend display audio"). V2: limit this for BACO and mode1 reset only V3: try 1st to use pm_runtime_autosuspend_expiration() to query how much time is left. Use default setting on failure Signed-off-by:Evan Quan <evan.quan@amd.com> Reviewed-by:

The current GWS usage model will only allows a single GWS-enabled process to be active on the GPU at once. This ensures that a barrier-using kernel gets a known amount of GPU hardware, to prevent deadlock due to inability to go beyond the GWS barrier. The HWS watches how many GWS entries are assigned to each process, and goes into over-subscription mode when two processes need more than the 64 that are available. The current KFD method for working with this is to allocate all 64 GWS entries to each GWS-capable process. When more than one GWS-enabled process is in the runlist, we must make sure the runlist is in over-subscription mode, so that the HWS gets a chained RUN_LIST packet and continues scheduling kernels.

Rather than only enabling GWS support based on the hws_gws_support modparm, also check whether the GPU's HWS firmware supports GWS. Leave the old modparm in place in case users want to test GWS on GPUs not yet in the support list. v2: fix broken syntax from the first patch. Signed-off-by:

Since commit "Move to a per-IB secure flag (TMZ)", we've been seeing hangs in GFX. We need to send FRAME CONTROL stop/start back-to-back, every time we flip the TMZ flag. That is, when we transition from TMZ to non-TMZ we have to send a stop with TMZ followed by a start with non-TMZ, and similarly for transitioning from non-TMZ into TMZ. This patch implements this, thus fixing the GFX hang. v1 -> v2: As suggested by Luben, and accept part of implemetation from this patch: - Put "secure" closed to the loop and use optimization - Change "secure" to bool again, and move "secure == -1" out of loop. v3: Small fixes/optimizations.
