Subject: [PATCH v2] drm/msm: Fix the a650 hw_apriv check
Date: Tue, 15 Sep 2020 10:35:51 -0600 [thread overview]
Message-ID: <20200915163551.1713571-1-jcrouse@codeaurora.org> (raw)
Commit 604234f33658 ("drm/msm: Enable expanded apriv support for a650")
was checking the result of adreno_is_a650() before the gpu revision
got probed in adreno_gpu_init() so it was always coming across as
false. Snoop into the revision ID ahead of time to correctly set the
hw_apriv flag so that it can be used by msm_gpu to properly setup
global buffers.
