STRUCT INTEL_TH_OUTPUT(9)

💖 NAME 💖

okay bestie, welcome to the struct intel_th_output(9) page from the Kernel API Manual — this is the descriptor for INTEL_TH_OUTPUT type devices, and it's lowkey the little ID card that tells everyone which output port is which. 🪪✨

🌸 SYNOPSIS 🌸

struct intel_th_output {
    int port;
    unsigned int    type;
    unsigned int    scratchpad;
    bool multiblock;
    bool active;
 };

🎀 Members 🎀

• port — the output port number, assigned by the switch. 🔢
• type — GTH_{MSU,CTP,PTI}. 🏷️
• scratchpad — scratchpad bits to flag when this output is enabled. 🚩
• multiblock — true for multiblock output configuration. 🧱
• active — true when this output is enabled. ✅

💫 Description 💫

okay so this is an output port descriptor. The switch driver uses it to tell which output port this output device corresponds to. 🎯 It gets filled in at the output device's probe time by switch::assign. Then it's passed from the output device driver to switch related code to enable/disable its port. literally the handoff bestie. 🫶
