2024-06-14drm/amdgpu/kfd: remove is_hws_hang and is_resettingYunxiang Li1-1/+0
is_hws_hang and is_resetting serves pretty much the same purpose and they all duplicates the work of the reset_domain lock, just check that directly instead. This also eliminate a few bugs listed below and get rid of dqm->ops.pre_reset. kfd_hws_hang did not need to avoid scheduling another reset. If the on-going reset decided to skip GPU reset we have a bad time, otherwise the extra reset will get cancelled anyway. remove_queue_mes forgot to check is_resetting flag compared to the pre-MES path unmap_queue_cpsch, so it did not block hw access during reset correctly.

MES can concurrently schedule queues on the device that require exclusive device access if marked exclusively_scheduled without the requirement of GWS. Similar to the F32 HWS, MES will manage quality of service for these queues. Use this for cooperative groups since cooperative groups are device occupancy limited. Since some GFX11 devices can only be debugged with partial CUs, do not allow the debugging of cooperative groups on these devices as the CU occupancy limit will change on attach. In addition, zero initialize the MES add queue submission vector for MES initialization tests as we do not want these to be cooperative dispatches.

2023-06-09drm/amdkfd: update process interrupt handling for debug eventsJonathan Kim1-1/+3
The debugger must be notified by any debugger subscribed exception that comes from hardware interrupts. If a debugger session exits, any exceptions it subscribed to may still have interrupts in the interrupt ring buffer or KGD/KFD pipeline. To prevent a new session from inheriting stale interrupts, when a new queue is created, open an interrupt drain and allow the IH ring to drain from a timestamped checkpoint. Then inject a custom IV so that once the custom IV is picked up by the KFD, it's safe to close the drain and proceed with queue creation. The drain must also be on debug disable as SW interrupts may still be processed. Drain at this time and clear all the exception status. The debugger may also not be attached nor subscibed to certain exceptions so forward them directly to the runtime. GFX10 also requires its own IV processing, hence the creation of kfd_int_process_v10.c. This is because the IV from SQ interrupts are packed into a new continguous format unlike GFX9. To make this clear, a separate interrupting handling code file was created.

The PSP TA will only provide xGMI topology info for links between GPU sockets so links between partitions from different sockets will be hardcoded as 3 xGMI hops with 1 hops weighted as xGMI and 2 hops weighted with a new intra-socket weight to indicate the longest possible distance. If the link between a partition and the CPU is non-PCIe, then assume the CPU (CCDs) is located within the same socket as the partition and represent the link as an intra-socket weighted single hop XGMI link with memory bandwidth. Links between partitions within a single socket will be abstracted as single hop xGMI links weighted with the new intra-socket weight and will have memory bandwidth. Finally, use the unused function bits in the location ID to represent the coordinates of the compute partition within its socket. A follow on patch will resolve the requirement for GPU socket xGMI link representation sometime later.
