STRUCT EC_PARAMS_CEC_SET(9)

🌸 NAME 🌸

struct ec_params_cec_set — CEC parameters set. Yep bestie, this is the Kernel API Manual page for it, and we're gonna make it make sense 💅.

✨ SYNOPSIS ✨

Here's the struct in all its bitfield glory:

       struct ec_params_cec_set {
           uint8_t cmd : 4;
           uint8_t port : 4;
           uint8_t val;
        };

💅 Members 💅

• cmd — the parameter type, bestie. It can be CEC_CMD_ENABLE or CEC_CMD_LOGICAL_ADDRESS.
• port — the CEC port to set the parameter on. Like, which port is getting the makeover 🎀.
• val — okay so this one is lowkey a two-for-one:
  • if cmd is CEC_CMD_ENABLE, this field can be 0 to disable CEC or 1 to enable CEC functionality. Off or on, periodt.
  • if cmd is CEC_CMD_LOGICAL_ADDRESS, this field encodes the requested logical address between 0 and 15, or 0xff to unregister. That's the whole range, iykyk.
