STRUCT AMDXDNA_DRM_QUERY_HWCTX(9)

💅 struct amdxdna_drm_query_hwctx(9) — like, the whole Kernel API Manual, but make it make sense 🫶

okay bestie, sit down, hydrate, and let me tell you about struct amdxdna_drm_query_hwctx ✨ this is the kernel API manual page for it, and honestly? she's giving receipts. this struct is literally the data for a single context — one context, all the tea ☕

---

🌸 NAME 🌸

struct amdxdna_drm_query_hwctx — the data for a single context. that's it, that's the vibe 💖

---

✨ SYNOPSIS ✨

here's the whole glow-up, laid out exactly:

struct amdxdna_drm_query_hwctx {
    __u32 context_id;
    __u32 start_col;
    __u32 num_col;
    __u32 pad;
    __s64 pid;
    __u64 command_submissions;
    __u64 command_completions;
    __u64 migrations;
    __u64 preemptions;
    __u64 errors;
};

no cap, that's the entire struct. every field is a little main character, so let's meet the cast 🎀

👑 Members 👑

• context_id — the ID for this context. her government name, basically 💅
• start_col — the starting column for the partition assigned to this context. where her section of the world begins ✨
• num_col — the number of columns in the partition assigned to this context. how much real estate she's working with 📐
• pad — structure padding. not important, just vibes. she's there so the layout stays cute 🌸
• pid — the Process ID of the process that created this context. the origin story, the parent, the one who brought her into this world 😭🫶
• command_submissions — the number of commands submitted to this context. all the asks, all the requests, all the "hey can you—" 💌
• command_completions — the number of commands completed by this context. she ate and left no crumbs 🔥
• migrations — the number of times this context has been moved to a different partition. she's been relocated, she's seen things 💀
• preemptions — the number of times this context has been preempted by another context in the same partition. interrupted mid-sentence by someone in her own group chat 🙈
• errors — the errors for this context. the L's. we keep them anyway 💜
