drm/amd/display: DP HDCP Compliance 1A-08/09 tests fail

2021-02-09T20:31:00Z

[Why] Current implementation of mod_hdcp_hdcp2_validate_ake_cert() does not process HDCP status message TA_HDCP2_MSG_AUTHENTICATION_STATUS__SIGNATURE_CERTIFICAT_ERROR. As a result, when there is a signature certificate error, mod_hdcp_hdcp2_validate_ake_cert would return the default status, which is success. [How] For all messages other than TA_HDCP2_MSG_AUTHENTICATION_STATUS__SUCCESS and TA_HDCP2_MSG_AUTHENTICATION_STATUS__RECEIVERID_REVOKED, return status as failure.

drm/amd/display: fix calculation for the pwl backlight curve

2021-02-02T17:09:46Z

[Why] The PWL backlight curve is used by the firmware to convert between brightness and linear PWM value. Driver has a backlight LUT, but the firmware holds a PWL curve and interpolates between points. The calculations are incorrect leading to slightly off backlight values being programmed.

drm/amd/display: correct some hdcp variable naming

2021-02-02T17:09:09Z

[why] In HDCP update stream config interface, some variables are named as xxx_supported, but in fact the variable indicates whether or not xxx_enabled. Correct the naming so it is less confusing to read the code. Signed-off-by: Wenjing Liu Reviewed-by: George Shen Acked-by: Anson Jacob Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Modify the hdcp device count check condition

[why] Some MST display may not report the internal panel to DEVICE_COUNT, that makes the check condition always failed.

drm/amd/display: Fix OGAM LUT calculation precision

2020-12-15T16:34:35Z

[Why] The OGAM LUT precision was accumulating too much error in the higher end. [How] Instead of calculating all points of the LUT in relation to the previous ones, perform a full calculation in one of the intermediate segments to stop error propagation.
