🌸 NAME 🌸

radeon_ring_alloc — allocate space on the ring buffer 🎀

🦋 SYNOPSIS 🦋

int radeon_ring_alloc (struct radeon_device *rdev , struct radeon_ring
*ring , unsigned ndw );

like, that's the whole signature, copy it exactly, don't get creative 💅

✨ ARGUMENTS ✨

  • rdev — a radeon_device pointer 🫶 that's your device handle, main character energy
  • ring — the radeon_ring structure holding ring information 🎀 she's literally holding the whole ring's lore
  • ndw — number of dwords to allocate in the ring buffer 💖 the amount, in dwords, fr fr

💜 DESCRIPTION 💜

so what she does: allocate ndw dwords in the ring buffer (all asics). yes, all asics, no exceptions 👑

returns 0 on success, error on failure — that's the vibe check, if you get 0 you're slaying, anything else is not it 😭

🔥 SEE ALSO 🔥
