Subject: [RFC PATCH v2 05/18] rust: drm: expose <drm/display/drm_hdcp.h> HDCP 2.2 message definitions
Date: Fri, 3 Jul 2026 04:00:52 +0100 [thread overview]
Message-ID: <20260703030123.2814-6-mike@fireburn.co.uk> (raw)
In-Reply-To: <20260703030123.2814-1-mike@fireburn.co.uk>
Add <drm/display/drm_hdcp.h> to the bindings so Rust DRM drivers can use
the canonical HDCP 2.2 message IDs (HDCP_2_2_AKE_INIT ..
HDCP_2_2_REP_STREAM_READY), length constants and hdcp2_* message structs
instead of redefining them. The header only pulls in <linux/types.h>, so
it adds no new heavy dependencies.
The Vino DisplayLink DL3 driver uses these for its HDCP 2.2 AKE/LC/SKE
handshake (carried over a vendor USB transport rather than the DP/HDMI
HDCP transport, so only the message definitions are reused, not the
drm_hdcp_helper state machine).
