📦 version 7.3.1, in nixpkgs unstable

💖 radeon_scratch_get(9) 💖

okay so bestie, welcome to the radeon_scratch_get(9) page — it's a Kernel API Manual situation, and honestly it's a whole little icon. sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

radeon_scratch_get — allocate a scratch register ✨

🎀 SYNOPSIS 🎀

int radeon_scratch_get (struct radeon_device *rdev , uint32_t *reg );

like, that's the whole signature. she's compact, she's efficient, she's giving main character energy 🔥

🌸 ARGUMENTS 🌸

  • rdev — a radeon_device pointer. literally the GPU device handle, she's the whole vibe 💅
  • reg — the scratch register mmio offset. that's your out-param, she tells you where the register lives 🎯

🦋 DESCRIPTION 🦋

so what does she actually do? she allocates a CP scratch register for use by the driver — and yes, that's on all asics, no exceptions, no pick-me behavior, she's for everyone 💖

returns 0 on success 🎉 or -EINVAL on failure 😭 that's it, that's the whole story, no cap.

ngl the description here is short but that's the point — one job, done well. she's lowkey iconic for that.

🌈 SEE ALSO 🌈

okay bestie this list is long but every single one of these is part of the family, so we're listing them all, periodt 🫶

and the kernel file where all this lives, fr fr:

Kernel file ./drivers/gpu/drm/radeon/radeon_device.c

and that's the page!! 🧚 she ships out of ./drivers/gpu/drm/radeon and this cutie is dated October 2026 — mwah, slay, go allocate some scratch registers responsibly 💜✨🎀
