💅 radeon_doorbell_get(9) — the Kernel API Manual, bestie edition 🎀

okay so welcome to the Kernel API Manual entry for radeon_doorbell_get (like the title says, that's the whole name, no notes ✨). it's giving "small function, big responsibility" and honestly? we're obsessed. let's get into it 🦋

✨ NAME ✨

radeon_doorbell_get — literally just allocate you a doorbell entry 🔔💖

🌸 SYNOPSIS 🌸

int radeon_doorbell_get (struct radeon_device *rdev , u32 *doorbell );

yes bestie, it takes two arguments and returns an int, that's the whole vibe check 🫶

🎀 ARGUMENTS 🎀

  • rdev — the radeon_device pointer, aka your main character pointer 💅
  • doorbell — the doorbell index 🛎️

🌈 DESCRIPTION 🌈

so what it does: it allocates a doorbell for use by the driver (and this is for all asics, no cap). then it returns 0 on success, or -EINVAL on failure 🫠. that's it. that's the function. iconic, lowkey ✨

ngl, -EINVAL is your "something was wrong with the args" era 😭 so check yourself before you wreck yourself fr fr.
