[igt-dev] [PATCH i-g-t v4 2/2] kms_content_protection: Add Content Protection test
Ramalingam C
ramalingam.c at intel.com
Mon Oct 22 14:23:49 UTC 2018
Pretty simple test:
- picks the hdcp capable output with suitable pipe and apply modeset.
- checks the connected sink's hdcp capability through debugfs
- apply a FB and wait for the flip completion.
- clears the content protection property
- verifies that it clears
- sets the content protection property to desired
- verifies that it transitions to enabled
- incase of timeout three reattempts are implemented
- clear the content protection property and modeset on the crtc
Above steps are repeated on all HDCP capable connectors for both
legacy and atomic subtests.
v2:
dynamic subtests are dropped [Daniel]
v3:
debugfs is used to detect the sink's hdcp capability [Daniel]
data structure is made as global variable.
v4:
debugfs file from connector's debugfs dir is used [Daniel]
