STRUCT KFD_IOCTL_DBG_TRAP_QUERY_EXCEPTION_INFO_ARGS(9)

🦋 struct kfd_ioctl_dbg_trap_query_exception_info_args(9) — Kernel API Manual 🦋

🌸 NAME 🌸

okay bestie, meet struct kfd_ioctl_dbg_trap_query_exception_info_args — the arguments for KFD_IOC_DBG_TRAP_QUERY_EXCEPTION_INFO. That's the whole vibe: it's the lil' struct you pass for that query. 🫶

✨ SYNOPSIS ✨

struct kfd_ioctl_dbg_trap_query_exception_info_args {
    __u64 info_ptr;
    __u32 info_size;
    __u32 source_id;
    __u32 exception_code;
    __u32 clear_exception;
};

💅 Members 💅

• info_ptr — (IN) pointer to exception info buffer to copy to. It's giving destination energy. 🎯
• info_size — (IN/OUT) exception info buffer size (bytes). Two-way street, bestie. 🔁
• source_id — (IN) target gpu or queue id. iykyk which one you're poking. 👀
• exception_code — (IN) target exception. The main character of this struct, lowkey. ⭐
• clear_exception — (IN) clear raised exception_code exception (0 = false, 1 = true). Yes, those exact values, no improv. 💅

📝 Description 📝

This one gets you additional info on a raised exception. Generic errors apply (see kfd_dbg_trap_operations). Return - 0 on SUCCESS.

If exception_code is EC_DEVICE_MEMORY_VIOLATION, copy info_size(OUT) bytes of memory exception data to info_ptr. If exception_code is EC_PROCESS_RUNTIME, copy saved kfd_runtime_info to info_ptr. Actual required info_ptr size (bytes) is returned in info_size.

bestie, clock that info_size is doing IN/OUT duty — the actual required info_ptr size comes back through it. Don't ignore the return glow-up. ✨
