drm/vkms: Fix license inconsistent

2019-02-20T09:29:15+00:00

commit 7fd56e0260a22c0cfaf9adb94a2427b76e239dd0 upstream. Fixes license inconsistent related to the VKMS driver and remove the redundant boilerplate comment.

drm/vkms: Fix plane duplicate_state

2019-01-22T20:09:57+00:00

commit 7cdf33ab02e01300e7e6289acbac9cd8759f8712 upstream. We need to handle allocation failures and bail out. While at it, tune the allocation failures down to debug level. syzbot injected an allocation failure and then hit this WARN_ON.

drm/vkms: Fix possible memory leak in _vkms_get_crc()

2018-09-21T08:50:45+00:00

'vaddr_out' is malloced in _vkms_get_crc() and should be freed before leaving from the error handling cases, otherwise it will cause memory leak.

drm/vkms: Enable/Disable cursor support with module option

Cursor support is not complete yet. Add module option 'enable_cursor' to enable/disable cursor support which is used for testing currently.

drm/vkms: Compute CRC with Cursor Plane

2018-09-11T17:56:19+00:00

This patch compute CRC for output frame with cursor and primary plane. Blend cursor with primary plane and compute CRC on the resulted frame. This currently passes cursor-size-change, and cursor-64x64-[onscreen, offscreen, sliding, random, dpms, rapid-movement] from igt kms_cursor_crc tests.

drm/vkms: Fix race condition around accessing frame number

2018-09-05T14:04:50+00:00

crtc_state is accessed by both vblank_handle() and the ordered work_struct handle vkms_crc_work_handle() to retrieve and or update the frame number for computed CRC. Since work_struct can fail, add frame_end to account for missing frame numbers. Use (frame_[start/end]) for synchronization between hrtimer callback and ordered work_struct handle. This patch passes the following subtests from igt kms_pipe_crc_basic test: bad-source, read-crc-pipe-A, read-crc-pipe-A-frame-sequence, nonblocking-crc-pipe-A, nonblocking-crc-pipe-A-frame-sequence Signed-off-by: Haneen Mohammed Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20180903211743.GA2773@haneenDRM

drm/crc: Cleanup crtc_crc_open function

2018-08-22T16:47:58+00:00

This patch make changes to allocate crc-entries buffer before enabling CRC generation. It moves all the failure check early in the function before setting the source or memory allocation. Now set_crc_source takes only two variable inputs, values_cnt we already gets as part of verify_crc_source. Changes since V1: - refactor code to use single spin lock Changes since V2: - rebase Changes since V3: - rebase on top of VKMS driver Signed-off-by: Mahesh Kumar Cc: dri-devel@lists.freedesktop.org Cc: Laurent Pinchart Cc: Haneen Mohammed Reviewed-by: Maarten Lankhorst Acked-by: Leo Li (V2) Reviewed-by: Laurent Pinchart (V3) Signed-off-by: Rodrigo Vivi Link: https://patchwork.freedesktop.org/patch/msgid/20180821083858.26275-3-mahesh1.kumar@intel.com
