STRUCT AMDXDNA_DRM_GET_ARRAY(9)

💅 struct amdxdna_drm_get_array(9) — a lil' field guide

okay so this is from the Kernel API Manual, bestie, and it's literally the struct you use when you wanna get an information array out of the amdxdna driver. yeah. that's the whole vibe. let's get into it 🫶

---

🌸 NAME 🌸

struct amdxdna_drm_get_array — Get information array. that's it, that's the tweet. she fetches info arrays, no cap 💖

---

✨ SYNOPSIS ✨

here's the whole struct, character for character, do NOT touch her:

struct amdxdna_drm_get_array {
    __u32 param;
    __u32 element_size;
    __u32 num_element;
    __u32 pad;
    __u64 buffer;
 };

(yeah there's a lil' extra space before the closing brace in the original, we're keeping it, that's her little quirk 🎀)

---

🦋 Members 🦋

🌈 param

the "what do you actually want, bestie" field. here's the supported lineup:

• DRM_AMDXDNA_HW_CONTEXT_ALL — returns all created hardware contexts. the whole friend group 🔥
• DRM_AMDXDNA_HW_LAST_ASYNC_ERR — returns the last async error. the receipts of what went wrong most recently 💀
• DRM_AMDXDNA_BO_USAGE — returns usage of heap/internal/external BOs. she's nosy and she's counting 👑

🌸 element_size

specifies the maximum element size… and then comes back with the actual element size. so she takes a suggestion and gives you the truth. iconic behavior honestly 💅

⭐ num_element

same energy: specifies the maximum number of elements, and returns the actual number of elements. she under-promises, she reports accurately 🧚

🎀 pad

MBZ. and if you don't know what that means, it's "must be zero" — like, literally set it to zero, no cap, don't be weird about it 🙈

💜 buffer

specifies the match conditions going in, returns the matched information array coming out. it's giving two-way street, it's giving bidirectional main character energy 🦋
