The HDCP 1.4 spec does not require the QUERY_STREAM_ENCRYPTION_STATUS
check, it was always a nice-to-have. After deploying this across various
devices, we've determined that some MST bridge chips do not properly

Hello,
This patchset pulls the HDCP protocol auth/exchange/check logic out from
i915 into a HDCP helper library which drivers can use to implement the
proper protocol and UAPI interactions for achieving HDCP.
Originally this was all stuffed into i915 since it was the only driver

This patch moves the hdcp atomic check from i915 to drm_hdcp so other

Hello again,
Here is v3 of the patch series. Notable changes include incorporating
review feedback involving:
- Changed dt-bindings to introduce new compatible string
- Code changes in msm driver as suggested by Stephen & Abhinav
- Fixed issues found by 0-day
Thank you to

This patch moves the hdcp atomic check from i915 to drm_hdcp so other
drivers can use it. No functional changes, just cleaned up some of the
code when moving it over.

Instead of forcing a modeset in the hdcp atomic check, simply return
true if the content protection value is changing and let the driver

This patch updates the connector's property value in 2 cases which were

1- Content type changes. The value should revert back to DESIRED from
ENABLED in case the driver must re-authenticate the link due to the
new content type.
2- Userspace sets

use the new drm_debug_syslog_enabled() call to avoid triggering

I think the only risk is getting UINT_MAX from userspace, since
drm_rect stores ints. However, it looks like check_src_coords() and
the check in __setplane_internal() should ensure those values are
pruned out.
