Subject: [PATCH] drm/v3d: HACK: gut runtime pm for now.
|
|
|
|
Something is still unstable -- on starting a new glxgears from an idle
|
|
X11, I get an MMU violation in high addresses. The CTS also failed
|
|
quite quickly. With this, CTS progresses for an hour before OOMing
|
|
(allocating some big buffers when my board only has 600MB available to
|
|
Linux)
|
