| H A D | kfd_int_process_v9.c | diff c3eb12dff0f9c6aa7f2916edaaec5545af5f379f Fri Apr 08 00:53:56 CEST 2022 Felix Kuehling <Felix.Kuehling@amd.com> drm/amdkfd: Ignore bogus signals from MEC efficiently
MEC firmware sometimes sends signal interrupts without a valid context ID
on end of pipe events that don't intend to signal any HSA signals.
This triggers the slow path in kfd_signal_event_interrupt that scans the
entire event page for signaled events. Detect these signals in the top
half interrupt handler to stop processing them as early as possible.
Because we now always treat event ID 0 as invalid, reserve that ID during
process initialization.
v2: Update firmware version checks to support more GPUs
