✨ uvd_v1_0_semaphore_emit ✨

okay bestie, welcome to the Kernel API Manual portion of the group chat 💖 this one's all about uvd_v1_0_semaphore_emit, and honestly? it's giving "small function, big responsibility" energy. let's get into it 🫶

🌸 NAME 🌸

uvd_v1_0_semaphore_emit — emit semaphore command 💅

🦋 SYNOPSIS 🦋

bool uvd_v1_0_semaphore_emit (struct radeon_device *rdev , struct
radeon_ring *ring , struct radeon_semaphore *semaphore , bool emit_wait
);

like, look at that signature. four arguments, returns a bool, absolutely iconic. 🎀

💜 ARGUMENTS 💜

  • rdev — a radeon_device pointer. yes, the whole device. main character energy fr fr 👑
  • ring — a radeon_ring pointer. it's the ring we're playing with ✨
  • semaphore — the semaphore to emit commands for. literally what it says on the tin 🎯
  • emit_wait — true if we should emit a wait command 🙈 (so like, false means the other thing, iykyk)

⭐ DESCRIPTION ⭐

Emit a semaphore command (either wait or signal) to the UVD ring. that's it, that's the vibe — one command, semaphore-flavoured, straight to the UVD ring. no cap, it's lowkey that simple 💀

ngl this is the whole description in the original too, so don't come for me — some functions just know exactly what they are and don't need a whole essay 💅

🌈 SEE ALSO 🌈

the kernel file lives at ./drivers/gpu/drm/radeon/uvd_v1_0.c, and here's the whole friend group (aka the sibling functions you'll probably want to meet too):

and that's a wrap, bestie 🧚💖 this cutie comes to you from ./drivers/gpu/drm/radeon, dated October 2026, and it's officially the uvd_v1_0_semaphore_emit(9) page — slay, periodt, go emit some semaphores responsibly 🎀✨
