💅 radeon_ring_lock(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the radeon_ring_lock(9) page, straight out of the Kernel API Manual ✨ this one's short and sweet — she locks a ring, she grabs some space on it, she comes back with an int. iconic behavior honestly 🦋

🌸 NAME 🌸

radeon_ring_lock — lock the ring and allocate space on it 💫

✨ SYNOPSIS ✨

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

like, that's the whole signature, no notes 💅

🫶 ARGUMENTS 🫶

  • rdev — a radeon_device pointer. your device, your main character 🔥
  • ring — a radeon_ring structure holding ring information. yes, the ring. she contains multitudes ✨
  • ndw — number of dwords to allocate in the ring buffer. count 'em, bestie 🔢

💖 DESCRIPTION 💖

So what she does: locks the ring and allocates ndw dwords in the ring buffer — and this applies to all asics, no cap, every single one of them 🫶

Returns 0 on success, error on failure. that's it, that's the whole vibe check 🌈

ngl, always check that return value — an error is an error and she will tell you about it 😭

👑 SEE ALSO 👑

The kernel file lives at ./drivers/gpu/drm/radeon/radeon_ring.c — go read her, she's literally right there 📂

And the whole ring crew, in this exact order, because we do not disrespect the list 🙈:
