From: Chunming Zhou Date: Tue, 21 Jul 2015 08:04:39 +0000 (+0800) Subject: drm/amdgpu: prepare job before push to sw queue for pte ring X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4274f5d45cf11f88d7380702a7147b70553ddd6e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/amdgpu: prepare job before push to sw queue for pte ring user mode will still use pte ring as a normal ring. if the prepare job generates another command(update pte) on its ring in scheduler, then will kill scheduler which is going to waiting later job but pending running job.
