From 84f48df530a6ce0423920ebd8fd4e1dde52dd09f Mon Sep 17 00:00:00 2001 From: Vedashree Vidwans Date: Wed, 7 Aug 2019 14:07:57 -0700 Subject: gpu: nvgpu: use vpr resize API This patch adds nvgpu API in linux and qnx to query vpr resize. The new API nvgpu_is_vpr_resize_enabled() is used in nvgpu_submit_channel_gpfifo(). Previously, if non-deterministic channel has timeout disabled and GPU cannot railgate on some platform, then channel doesn't power ref count and results in video freeze. This requires non-determinstic channel job tracking to be enabled if vpr resize is supported or if GPU can railgate.
