r600_dma_is_lockup(9)

okay bestie, welcome to the r600_dma_is_lockup(9) page from the Kernel API Manual 💅✨ this one is short and sweet, and it's literally here to check if the DMA engine is locked up. no cap.

🎀 NAME 🎀

r600_dma_is_lockup - Check if the DMA engine is locked up.

💖 SYNOPSIS 💖

bool r600_dma_is_lockup (struct radeon_device *rdev , struct radeon_ring
       *ring );

🦋 ARGUMENTS 🦋

these two are the whole cast, and they're giving main character energy:

• rdev — a radeon_device pointer, periodt.
• ring — a radeon_ring structure holding ring information.

🌈 DESCRIPTION 🌈

so like, this function checks if the async DMA engine is locked up. it returns true if the engine appears to be locked up, and false if not. that's the tea ☕✨
