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 π β and it's about a little ring helper that has your back. Let's get into it π«Ά
πΈ NAME πΈ
amdgpu_ring_emit_reg_write_reg_wait_helper β the ring helper, no cap π
π¦ SYNOPSIS π¦
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 β¨
π ARGUMENTS π
ringβ the ring you're writing to, bestie π«reg0β the register you're writingreg1β the register you're gonna wait onrefβ the reference value you write/wait onmaskβ the mask you wait on
π₯ DESCRIPTION π₯
okay so this is the helper for rings that don't support write and wait in a single oneshot packet π 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 π
