ENUM IPC_UL_USR_OP(9)

💅 enum ipc_ul_usr_op(9)

okay so this is a page from the Kernel API Manual bestie, and it's about enum ipc_ul_usr_op — literally the control operation that tells the code which right action to run on the user interface. it's giving "one enum to rule the vibes" ✨

🌸 SYNOPSIS 🌸

enum ipc_ul_usr_op {
    UL_USR_OP_BLOCKED ,
    UL_MUX_OP_ADB ,
    UL_DEFAULT

};

like, that's the whole thing. three constants. she's simple, she's iconic 💅

🎀 Constants 🎀

• UL_USR_OP_BLOCKED — the uplink app was blocked until CP confirms that the uplink buffer was consumed, and that whole thing was triggered by the IRQ. so yeah, blocked until the confirmation lands, no cap 🫶
• UL_MUX_OP_ADB — in MUX mode the UL ADB shall be added to the free list. that's the whole assignment, periodt ✨
• UL_DEFAULT — SKB in non muxing mode. that's it, that's the vibe 😌
