STRUCT I915_HDCP_OPS(9)

💅 NAME 💅

okay so bestie, welcome to the struct i915_hdcp_ops(9) page from the Kernel API Manual ✨ this is literally the ops for HDCP2.2 services, and it's giving “small struct, serious business” energy. no cap. 🫶

✨ SYNOPSIS ✨

here's the struct in full, verbatim, because we do not mess with C signatures:

struct i915_hdcp_ops {
    struct module *owner;
    int (*initiate_hdcp2_session)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_ake_init *ake_data);
    int (*verify_receiver_cert_prepare_km)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_ake_send_cert *rx_cert, bool *km_stored, struct hdcp2_ake_no_stored_km *ek_pub_km, size_t *msg_sz);
    int (*verify_hprime)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_ake_send_hprime *rx_hprime);
    int (*store_pairing_info)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_ake_send_pairing_info *pairing_info);
    int (*initiate_locality_check)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_lc_init *lc_init_data);
    int (*verify_lprime)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_lc_send_lprime *rx_lprime);
    int (*get_session_key)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_ske_send_eks *ske_data);
    int (*repeater_check_flow_prepare_ack)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_rep_send_receiverid_list *rep_topology, struct hdcp2_rep_send_ack *rep_send_ack);
    int (*verify_mprime)(struct device *dev, struct hdcp_port_data *data, struct hdcp2_rep_stream_ready *stream_ready);
    int (*enable_hdcp_authentication)(struct device *dev, struct hdcp_port_data *data);
    int (*close_hdcp_session)(struct device *dev, struct hdcp_port_data *data);
};

🎀 Members 🎀

each member is a function-pointer bestie with a job. roster time, iykyk:

• owner — hdcp module.
• initiate_hdcp2_session — initiates a Wired HDCP2.2 Tx Session and prepares AKE_Init.
• verify_receiver_cert_prepare_km — verifies the Receiver Certificate AKE_Send_Cert and prepares AKE_Stored_Km/AKE_No_Stored_Km.
• verify_hprime — verifies AKE_Send_H_prime.
• store_pairing_info — stores the pairing info received.
• initiate_locality_check — prepares LC_Init.
• verify_lprime — verifies lprime.
• get_session_key — prepares SKE_Send_Eks.
• repeater_check_flow_prepare_ack — validates the Downstream topology and prepares rep_ack.
• verify_mprime — verifies mprime.
• enable_hdcp_authentication — marks a port as authenticated.
• close_hdcp_session — closes the Wired HDCP Tx session per port. This also disables the authenticated state of the port.
