💅 radeon_gart_table_vram_alloc — a Kernel API Manual moment 💅

okay so this is a page from the Kernel API Manual, section 9, and bestie, it's a whole little vibe about giving the GART page table some video memory. super specific, super iconic, let's get into it 🎀

✨ NAME ✨

radeon_gart_table_vram_alloc — allocate vram for gart page table 💖

like, that's literally it. the whole job. it allocates VRAM for the GART page table. no cap.

🌸 SYNOPSIS 🌸

int radeon_gart_table_vram_alloc (struct radeon_device *rdev );

that's the whole call, copy it exactly please, character for character, because kernel signatures do not play 🫶

🦋 ARGUMENTS 🦋

  • rdev — a radeon_device pointer. that's it, that's the argument. it's the radeon device you're doing this for 👑

💜 DESCRIPTION 💜

so the way this works is it allocates video memory for the GART page table — and honestly? only for the specific asics that need it, namely pcie r4xx, r5xx+. these asics require the gart table to live in video memory. like, they simply will not accept it anywhere else. main character asics only, i guess 💅

return value check, because we love clarity:

  • returns 0 for success — slay ✨
  • returns an error for failure — not slay, but important to know 😭
bestie pls actually check the return value. 0 means we ate, anything else means something went wrong and you should handle it. no vibes-based error handling 🙈

🔥 SEE ALSO 🔥

the kernel file for all of this lives at:

./drivers/gpu/drm/radeon/radeon_gart.c

and here's the whole friend group, all of them, in order, no one left out 🫶:

anyway that's the page!! this one came out of ./drivers/gpu/drm/radeon and it's dated October 2026, so shoutout to the future i guess 🌈⭐ go allocate that vram and have the best day, mwah 💋🧚
