pop_back() was causing a seg fault when pp_dpm_pcie file is empty and returns whitespace. Signed-off-by: Divya Shikre <[email protected]> Change-Id: I888f1f79751cd456e43751a5b96d08560a039677 (cherry picked from commit ec71380)
SMI lib function rsmi_event_notification_get read events from all GPUs, each event returned with device dv_idx. Currently we create read thread for each GPU, it is not necessary because each thread reads same events, and each thread display events from other GPUs with incorrect GPU index. Create one read thread for multiple GPUs, and display event with correct GPU index received from data.dv_idx. Signed-off-by: Philip Yang <[email protected]>
Update kfd_ioctl.h from KFD to add HMM migration and recoverable page fault, queue eviction and restore event, and event triggers defines. Update rocm_smi.h to add new SMI notification events and triggers defines, with the same enum value as kfd_ioctl.h, to avoid value translation in smi lib. Change fscanf %63s format to %MAX_EVENT_NOTIFICATION_MSG_SIZE[^\n] to read entire line as one message. Signed-off-by: Philip Yang <[email protected]>
Use SMI_EVENT_ALL_PROCESS to receive event from all processes because HMM migration events are per process event, KFD requires this flag plus super user premission to receive events from other process, so showevents to relaunchAsSudo if arguments are in new event list. User can specify event name in short format, for example "--showevents migrate" will show MIGRATE_START, MIGRATE_END events. Define message size using macro from rocm_smi.h Signed-off-by: Philip Yang <[email protected]>
Add new event names defines, set event mask RSMI_EVT_NOTIF_ALL_PROCESS to receive events from all processes. Add protection check in case new event type returns from KFD, to avoid out of range access segmentation fault. Signed-off-by: Philip Yang <[email protected]>
