From 1db8c142b6c557a951e8f9866b98953fe91cbdd6 Mon Sep 17 00:00:00 2001 From: Sharat Masetty Date: Thu, 29 Nov 2018 15:35:20 +0530 Subject: drm/scheduler: Add drm_sched_suspend/resume_timeout() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds two new functions to help client drivers suspend and resume the scheduler job timeout. This can be useful in cases where the hardware has preemption support enabled. Using this, it is possible to have the timeout active only for the ring which is active on the ringbuffer. This patch also makes the job_list_lock IRQ safe.
