Subject: [PATCH] drm/radeon: don't init gpuvm if accel is disabled
Date: Wed, 28 Jan 2015 14:41:35 -0500 [thread overview]
Message-ID: <1422474095-20982-1-git-send-email-alexander.deucher@amd.com> (raw)
If acceleration is disabled, it does not make sense
to init gpuvm since nothing will use it. Moreover,
if radeon_vm_init() gets called it uses accel to try
and clear the pde tables, etc. which results in a bug.
Bug:
