okay so bestie, welcome to the dma_fence_unwrap_merge(9) page ✨ this one lives in the Kernel API Manual and it's literally about taking a whole pile of fences, unwrapping them, and merging them back into one flat vibe. no cap, it's giving "cleanup era" πŸ§ΉπŸ’–


🌸 NAME 🌸

dma_fence_unwrap_merge β€” unwrap and merge fences πŸ¦‹


✨ SYNOPSIS ✨

dma_fence_unwrap_merge (... );

πŸŽ€ ARGUMENTS πŸŽ€

  • ... β€” variable arguments πŸ’« like, as many as you need, it's variadic and it's thriving.

πŸ‘‘ DESCRIPTION πŸ‘‘

So here's the tea β˜•: all the fences you hand over as parameters get unwrapped and then merged back together as a flat dma_fence_array. Slay. πŸ’…

It's lowkey perfect if you've got multiple containers that need to be merged together β€” that's literally the whole point, iykyk 🫢

It's implemented as a macro so it can allocate the necessary arrays on the stack and account the stack frame size to the caller. yes bestie, stack frame size accounting, we love a responsible icon πŸ’€βœ¨

On memory allocation failure it returns NULL 😭 β€” otherwise you get a dma_fence object representing all the given fences. main character return value fr fr πŸ‘‘
