amdgpu_seq64_alloc(9)

🌸 amdgpu_seq64_alloc(9) — like, the Kernel API Manual page, bestie 💅

okay so this is a page straight outta the Kernel API Manual (amdgpu_seq64_alloc(9), yes the whole name is the title, we love a self-titled icon 👑) and it's literally just one little function that grabs you some 64-bit memory from the seq64 pool. Short page, but it ate. let's get into it ✨

✨ NAME ✨

amdgpu_seq64_alloc — allocate a 64-bit memory 🎀

✨ SYNOPSIS ✨

int amdgpu_seq64_alloc (struct amdgpu_device *adev , u64 *va , u64
*gpu_addr , u64 **cpu_addr );

✨ ARGUMENTS ✨

so there's four things you gotta hand over, no cap:

• adev — the amdgpu_device pointer. your main character struct fr 🫶
• va — the VA you use to access the seq in process address space 💜
• gpu_addr — the GPU address you use to access the seq 🔥
• cpu_addr — the CPU address you use to access the seq 🌸

✨ DESCRIPTION ✨

Allocates a 64-bit memory from the seq64 pool. that's it, that's the whole vibe. short king 👑

✨ RETURN ✨

• 0 on success 💖
• a negative error code on failure 😭 (rip, but at least it's negative and not, like, mysterious)

✨ SEE ALSO ✨

go check out the kernel file ./drivers/gpu/drm/amd/amdgpu/amdgpu_seq64.c — it's giving source-of-truth 💅 and also these besties right here:

alright bestie, that's the whole page, mwah 🧚 this one lives at ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — timestamped for the future, iconic behavior honestly ⭐💜
