From 56e449603f0ac580700621a356d35d5716a62ce5 Mon Sep 17 00:00:00 2001 From: Luben Tuikov Date: Sat, 14 Oct 2023 21:15:35 -0400 Subject: drm/sched: Convert the GPU scheduler to variable number of run-queues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The GPU scheduler has now a variable number of run-queues, which are set up at drm_sched_init() time. This way, each driver announces how many run-queues it requires (supports) per each GPU scheduler it creates. Note, that run-queues correspond to scheduler "priorities", thus if the number of run-queues is set to 1 at drm_sched_init(), then that scheduler supports a single run-queue, i.e. single "priority". If a driver further sets a single entity per run-queue, then this creates a 1-to-1 correspondence between a scheduler and a scheduled entity.
