Subject: [PATCH 2/9] drm/amdgpu: Refine function amdgpu_csa_vaddr
Date: Thu, 6 Dec 2018 20:22:37 +0800	[thread overview]
Message-ID: <1544098957-21969-1-git-send-email-Rex.Zhu@amd.com> (raw)

on baremetal, driver create csa per ctx.
So add a function argument: ctx_id to
get csa gpu addr.
In Sriov, driver create csa per process,
so ctx id always 1.
