✨ amdgpu_ring_emit_reg_write_reg_wait_helper ✨

okay bestie so this is a page from the Kernel API Manual β€” yes, the actual kernel docs, we're in the big leagues now πŸ’… β€” and it's about a little ring helper that has your back. Let's get into it 🫢


🌸 NAME 🌸

amdgpu_ring_emit_reg_write_reg_wait_helper β€” the ring helper, no cap πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

void amdgpu_ring_emit_reg_write_reg_wait_helper (struct amdgpu_ring
*ring , uint32_t reg0 , uint32_t reg1 , uint32_t ref , uint32_t mask );

like literally that's the whole signature, copy it exactly, don't @ me ✨


πŸ’– ARGUMENTS πŸ’–

  • ring β€” the ring you're writing to, bestie πŸ’«
  • reg0 β€” the register you're writing
  • reg1 β€” the register you're gonna wait on
  • ref β€” the reference value you write/wait on
  • mask β€” the mask you wait on

πŸ”₯ DESCRIPTION πŸ”₯

okay so this is the helper for rings that don't support write and wait in a single oneshot packet 😭 like they just can't do it in one go, so this helper picks up the slack. it's giving "I'll do it in two because I have to" energy and honestly? iconic πŸ‘‘
