radeon_ring_test_lockup(9)

💅 radeon_ring_test_lockup — like, the Kernel API Manual edition, bestie

Okay so picture this: it's a page from the Kernel API Manual all about radeon_ring_test_lockup, and it's literally just one job — checking whether a ring is locked up by, yep, recording information. That's the whole vibe. ✨

🎀 NAME 🎀

radeon_ring_test_lockup — check if ring is lockedup by recording information

No cap, that's the entire mission statement. She records stuff so you can tell if the ring has given up on life. 💀

---

🌸 SYNOPSIS 🌸

bool radeon_ring_test_lockup (struct radeon_device *rdev , struct radeon_ring *ring );

Returns a bool, takes two pointers, that's it, that's the whole function. Slay. 🫶

---

🦋 ARGUMENTS 🦋

• rdev — the radeon device structure. Like, the big picture device object, the main character of the whole driver. 👑
• ring — the radeon_ring structure holding ring information. This is the one we're side-eyeing to see if it's locked up. 👀
