Use a reference counter instead of a lock to prevent process destruction while functions running out of process context are using the kfd_process structure. In many cases these functions don't need the structure to be locked. In the few cases that really do need the process lock, take it explicitly. This helps simplify lock dependencies between the process lock and other locks, particularly amdgpu and mm_struct locks. This will be important when amdgpu calls back to amdkfd for memory evictions.

This will be used to elliminate the use of the process lock for preventing concurrent process destruction. This will simplify lock dependencies between KFD and KGD. This also simplifies the process destruction in a few ways: * Don't allocate work struct dynamically * Remove unnecessary hack that increments mm reference counter * Remove unnecessary process locking during destruction Signed-off-by:

Increment the kfd_process.lead_thread's reference counter to make it safe to dereference. This is needed for getting a safe reference to the process' mm_struct. Signed-off-by:

This commit adds several debugfs entries for kfd: kfd/hqds: dumps all HQDs on all GPUs for KFD-controlled compute and SDMA RLC queues kfd/mqds: dumps all MQDs of all KFD processes on all GPUs kfd/rls: dumps HWS runlists on all GPUs Signed-off-by: -

Allow HWS to to execute multiple processes on the hardware concurrently. The number of concurrent processes is limited by the number of VMIDs allocated to the HWS. A module parameter can be used for limiting this further or turn it off altogether (mainly for debugging purposes). Signed-off-by:

After debugger is registered, the pqm_destroy_queue fails because is_debug is true, the queue should not be removed from process_queue_list since the count is not reduced. Test application calls debugger unregister without register debugger, add null pointer check protection to avoid crash for this case Signed-off-by:

A second-level user mode trap handler can be installed. The CWSR trap handler jumps to the secondary trap handler conditionally for any conditions not handled by it. This can be used e.g. for debugging or catching math exceptions. When CWSR is disabled, the user mode trap handler is installed as first level trap handler. Signed-off-by:

This hardware feature allows the GPU to preempt shader execution in the middle of a compute wave, save the state and restore it later to resume execution. Memory for saving the state is allocated per queue in user mode and the address and size passed to the create_queue ioctl. The size depends on the number of waves that can be in flight simultaneously on a given ASIC. Signed-off-by:

The trap handler is like an interrupt handler running on the GPU compute unit. It is needed for supporting CWSR (compute wave save/restore). This file defines an array with the pre-compiled GFXv8 shader ISA. The assembly code is included for reference in #if 0 ... #endif. Signed-off-by:

Felix Kuehling authored
Add wptr and mm parameters to hqd_sdma_load and pass these parameters from device_queue_manager through the mqd_manager. SDMA doesn't support polling while the engine believes it's idle. The driver must update the wptr. The new parameters will be used for looking up the updated value from the specified mm when SDMA queues are resumed after being disabled. Signed-off-by:

validate_fbc never fails a modeset. It's simply used to decide whether to use FBC or not. Calling it validate_fbc might be confusing to some so rename it to should_enable_fbc. With that let's also remove the DC_STATUS return code and return bool and make enable_fbc a void function since we never check it's return value and probably never want to anyways. Signed-off-by:
