The subsystem driver provides a mechanism for the application to register a user-defined function that gets called within an interrupt context.
Callback functions defined in the application code must be registered with provided handlers, using the following defined API:
int XV_HdmiRxSs1_SetCallback(XV_HdmiRxSs1 *InstancePtr,
u32 HandlerType,
void *CallbackFuncPtr,
void *CallbackRef);Available handlers are defined in xv_hdmirxss1.h:
- XV_HDMIRXSS1_HANDLER_CONNECT
- XV_HDMIRXSS1_HANDLER_AUX
- XV_HDMIRXSS1_HANDLER_AUD
- XV_HDMIRXSS1_HANDLER_LNKSTA
- XV_HDMIRXSS1_HANDLER_STREAM_UP
- XV_HDMIRXSS1_HANDLER_STREAM_DOWN
- XV_HDMIRXSS1_HANDLER_STREAM_INIT
- XV_HDMIRXSS1_HANDLER_FRL_CONFIG
- XV_HDMIRXSS1_HANDLER_FRL_START
- XV_HDMIRXSS1_HANDLER_TMDS_CONFIG
- XV_HDMIRXSS1_HANDLER_HDCP_AUTHENTICATE
- XV_HDMIRXSS1_HANDLER_VFP_CH
- XV_HDMIRXSS1_HANDLER_VRR_RDY
- XV_HDMIRXSS1_HANDLER_DYN_HDR
Note: The following HDMI 2.1 RX Subsystem interrupt callbacks are defined in the
driver, but they are not directly programmable in this release.
- XV_HDMIRXSS1_HANDLER_BRDGOVERFLOW
- XV_HDMIRXSS1_HANDLER_DDC
- XV_HDMIRXSS1_HANDLER_TMDS_CLK_RATIO
HDCP related callbacks are not covered in this document.
- XV_HDMIRXSS1_HANDLER_HDCP
- XV_HDMIRXSS1_HANDLER_HDCP_AUTHENTICATION_REQUEST
- XV_HDMIRXSS1_HANDLER_HDCP_AUTHENTICATED
- XV_HDMIRXSS1_HANDLER_HDCP_UNAUTHENTICATED
- XV_HDMIRXSS1_HANDLER_HDCP_STREAM_MANAGE_REQUEST
