2021-04-07T13:02:31+00:00

commit 6c5403173a13a08ff61dbdafa4c0ed4a9dedbfe0 upstream. We seem to have some more driver bugs than thought.

Revert "drm/ttm: Warn on pinning without holding a reference"

2021-03-25T09:13:34+00:00

This reverts commit 7d09e9725b5dcc8d14e101de931e4969d033a6ad which is commit 57fcd550eb15bce14a7154736379dfd4ed60ae81 upstream. It is causing too many warnings on 5.11.y, so should be dropped for now.

This reverts commit 0492006cc5ecb112d109a4b5cfa99798184a69e2 which is commit 6c5403173a13a08ff61dbdafa4c0ed4a9dedbfe0 upstream. It, and the following revert, are causing unneeded warnings to be sent to the kernel log. For 5.11 these are not needed at this point in time.

drm/ttm: Warn on pinning without holding a reference

2021-03-24T10:54:10+00:00

[ Upstream commit 57fcd550eb15bce14a7154736379dfd4ed60ae81 ] Not technically a problem for ttm, but very likely a driver bug and pretty big time confusing for reviewing code. So warn about it, both at cleanup time (so we catch these for sure) and at pin/unpin time (so we know who's the culprit).

drm/dp/mst: Export drm_dp_get_vc_payload_bw()

2021-02-02T15:31:37+00:00

This function will be needed by the next patch where the driver calculates the BW based on driver specific parameters, so export it. At the same time sanitize the function params, passing the more natural link rate instead of the encoding of the same rate. v2: - Fix function documentation.

drm/fb-helper: Rename dirty worker to damage worker

2020-11-24T08:27:55+00:00

The dirty worker handles all damage updates, instead of just calling the framebuffer's dirty callback. Rename it to damage worker. Also rename related variables accordingly. No functional changes are made.
