STRUCT KFD_IOCTL_DBG_TRAP_SET_WAVE_LAUNCH_MODE_ARGS(9)

💖 NAME 💖

struct kfd_ioctl_dbg_trap_set_wave_launch_mode_args — the arguments struct for KFD_IOC_DBG_TRAP_SET_WAVE_LAUNCH_MODE, bestie 💅

(this one lives in the Kernel API Manual, if you were wondering 🫶)

---

✨ SYNOPSIS ✨

struct kfd_ioctl_dbg_trap_set_wave_launch_mode_args {
    __u32 launch_mode;
};

look at her. one field. absolutely zero notes. she said "minimalism" and ate 🔥

---

🎀 Members 🎀

• launch_mode (IN) — the actual mode value, and for the lore you gotta go see kfd_dbg_trap_wave_launch_mode 💜

---

🌸 Description 🌸

okay so the whole job of this struct is literally just: set wave launch mode. that's it. that's the post 📮

generic errors apply here, so if something goes sideways, go read kfd_dbg_trap_operations for the whole error situation 😭

and the return? it's - 0 on SUCCESS. yes girl, zero on success, iconic behavior 👑

ngl, no cap — if you're poking at debug traps, keep kfd_dbg_trap_operations open in another tab. the generic errors live there and they will find you 🙈
