radeon_fence_wait_timeout(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to radeon_fence_wait_timeout(9) from the Kernel API Manual — the whole page is about waiting for a fence to signal, with a timeout, and we’re gonna make it make sense. 💖 No cap, it’s shorter than it looks.

💖 NAME 💖

radeon_fence_wait_timeout — wait for a fence to signal with timeout. 🎀

✨ SYNOPSIS ✨

long radeon_fence_wait_timeout (struct radeon_fence *fence , bool intr ,
       long timeout );

🎀 ARGUMENTS 🎀

  • fence — radeon fence object. literally the fence object we’re waiting on.
  • intr — use interruptible sleep. this is the little switch that decides how the sleep behaves.
  • timeout — maximum time to wait, or MAX_SCHEDULE_TIMEOUT for infinite wait. also, the return tea lives right here in the original page: it returns remaining time if the sequence number has passed, 0 when the wait timeout, or an error for all other cases.

💅 DESCRIPTION 💅

Wait for the requested fence to signal (all asics). 🦋 intr selects whether to use interruptable (true) or non-interruptable (false) sleep when waiting for the fence. so yes: true means interruptable sleep, false means non-interruptable sleep — that’s the whole selector vibe.

🦋 SEE ALSO 🦋
