radeon_sync_resv(9)

💖 radeon_sync_resv(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function from the radeon corner of the kernel, and it's literally just here to get your sync situation handled. the manual name is radeon_sync_resv(9) if you're keeping track 🎀

---

🌸 NAME 🌸

radeon_sync_resv — it uses the semaphores to sync to a reservation object. that's the whole vibe, no cap 💅

---

✨ SYNOPSIS ✨

int radeon_sync_resv (struct radeon_device *rdev , struct radeon_sync
*sync , struct dma_resv *resv , bool shared );

like… four args, one int back. classic. 🦋

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer. yes, the whole device. iconic.
• sync — the sync object you're adding fences from the reservation object to 🫶
• resv — the reservation object with the embedded fence. it's in there. iykyk.
• shared — a bool that's true if we should only sync to the exclusive fence. (yes, exactly like that, i'm not making the rules 😭)

---

🔥 DESCRIPTION 🔥

so what does it actually do? it syncs to the fence using the semaphore objects. that's it, that's the function, and honestly? she ate. ✨
