From bb13d763f251c28b08d996671c5146a2113fc9e7 Mon Sep 17 00:00:00 2001 From: Jonathan Kim Date: Fri, 24 Mar 2023 16:19:27 -0400 Subject: drm/amdkfd: fix kfd_suspend_all_processes Flush delayed restore work in kfd_suspend_all_queues instead of cancelling. Cancelling the work before it runs results in the queues becoming permanently disabled. Flushing the work ensures that the queue suspend/resume state stays balanced.
