STRUCT AMDXDNA_DRM_EXEC_CMD(9)

💅 struct amdxdna_drm_exec_cmd 💅

okay bestie, so this is a page from the Kernel API Manual — like, the official lore — and it's all about struct amdxdna_drm_exec_cmd, which is literally the "Execute command." struct. yes that's its whole NAME and it ate 💅

✨ SYNOPSIS ✨

here's the whole vibe, character for character, do not touch:

struct amdxdna_drm_exec_cmd {
    __u64 ext;
    __u64 ext_flags;
    __u32 hwctx;
    __u32 type;
    __u64 cmd_handles;
    __u64 args;
    __u32 cmd_count;
    __u32 arg_count;
    __u64 seq;
 };

🎀 Members 🎀

okay so every single one of these fields, no skipping, this is the whole cast 👑

• ext — MBZ. that's it. that's the whole field. MBZ, as in must be zero — it's giving "don't even try it, bestie" 🙈
• ext_flags — also MBZ. same energy, zero cap. leave it alone 💀
• hwctx — the hardware context handle. your lil backstage pass to the hardware vibe check 🎟️
• type — one of the command types in enum amdxdna_cmd_type. pick your fighter ✨
• cmd_handles — an array of command handles, or just the single command handle itself if there's literally only one (yes, it multitasks, main character energy fr fr) 👑
• args — array of arguments for all the command handles. group chat for args 🫶
• cmd_count — how many command handles are in the cmd_handles array. count 'em 🔢
• arg_count — how many arguments are in the args array. also count 'em 🔢
• seq — the returned sequence number for this command. it comes back to you, that's the whole point 🦋

⚠️ quick reminder that ext and ext_flags are MBZ — must be zero — like, do not put stuff in there, it's not that kind of field, ngl 😭
