💖 amdgpu_mes_rs64mem_setup_bitmaps(9) 💖

okay bestie, so this is a page straight outta the Kernel API Manual — the manual name is amdgpu_mes_r...etup_bitmaps(9) (yes the truncation is part of the vibe, we don't make the rules) and it's literally all about one little function. let's get into it 🫶

---

✨ NAME ✨

amdgpu_mes_rs64mem_setup_bitmaps — the girlies allocate bitmaps after querying MES, and honestly? iconic. 🎀

---

🌸 SYNOPSIS 🌸

int amdgpu_mes_rs64mem_setup_bitmaps (struct amdgpu_mes *mes );

that's it. that's the whole call. copy it exactly, no cap 💅

---

🦋 ARGUMENTS 🦋

• mes — the MES instance, aka the main character of this whole operation 👑

---

⭐ DESCRIPTION ⭐

so here's the tea: this function gets called after QUERY_SCHEDULER_STATUS has returned and MES has already written the array sizes into the GPU buffer. like, the sizes are already sitting there, she's just showing up fashionably late to read them 💀

what does she do with them? she reads the sizes and then allocates the tracking bitmaps. that's the whole job. lowkey simple, highkey essential. 🧚

and the return value:

• Returns 0 on success 🎉
• Returns a negative errno on failure 😭

fr fr bestie, watch that return value — negative errno means something went sideways, don't just ignore it 🙈

and that's the whole page bestie, you ate that 💅✨ this one's living in ./drivers/gpu/drm/amd/amdgpu, dated October 2026, so mark your calendars accordingly 🗓️💖 mwah, go allocate something cute 🎀🦋
