unreserve_bo_and_vms(9)

🌸 NAME 🌸

okay so bestie, you have landed on unreserve_bo_and_vms(9) from the Kernel API Manual, and the whole assignment is literally Unreserve BO and VMs from a reservation context. lowkey iconic, highkey essential. 💖

✨ SYNOPSIS ✨

int unreserve_bo_and_vms (struct bo_vm_reservation_context *ctx , bool
       wait , bool intr );

🎀 ARGUMENTS 🎀

• ctx — the reservation context to unreserve, periodt. 💅
• wait — optionally wait for a sync object representing pending VM updates; yes, this is the optional-wait era. 🕰️
• intr — whether the wait is interruptible. that's the whole tea. 🫶

💅 DESCRIPTION 💅

so like, this function also frees any resources allocated in reserve_bo_and_(cond_)vm(s) — it's giving cleanup icon behavior, no cap. 🧹✨

and it returns the status from amdgpu_sync_wait. that's the return value, bestie, straight up. 💯
