dma_fence_array_create(9)

🌸 NAME 🌸

okay so bestie, this is dma_fence_array_create(9) from the Kernel API Manual — and it's literally all about creating a custom fence array 💅✨

dma_fence_array_create - Create a custom fence array 🎀

✨ SYNOPSIS ✨

the exact call, no cap:

struct dma_fence_array * dma_fence_array_create (int num_fences , struct
       dma_fence **fences , u64 context , unsigned seqno );

🎀 ARGUMENTS 🎀

• num_fences [in] — number of fences to add in the array 🧮
• fences [in] — array containing the fences 🦋
• context [in] — fence context to use 🎯
• seqno [in] — sequence number to use 🔢

💖 DESCRIPTION 💖

so the glow-up is: allocate a dma_fence_array object and initialize the base fence with dma_fence_init ✨ in case of error it returns NULL 😭

the caller should allocate the fences array with num_fences size and fill it with the fences it wants to add to the object. ownership of this array is taken, and dma_fence_put is used on each fence on release 🫶

and yes: if signal_on_any is true, the fence array signals if any fence in the array signals; otherwise it signals when all fences in the array signal 👑 periodt.
