πŸ’… panthor_vm_...ed_bos_resvs(9) πŸ’…

okay so bestie, welcome to the Kernel API Manual ✨ β€” yes it's a whole manual, yes it's about kernel graphics, no you're not allowed to be scared of it. this one's short and sweet, i promise 🫢


🌸 NAME 🌸

panthor_vm_prepare_mapped_bos_resvs β€” literally just: prepare resvs on VM BOs. that's it. that's the whole name section. slay πŸ’–

✨ SYNOPSIS ✨

int panthor_vm_prepare_mapped_bos_resvs (struct drm_exec *exec , struct
panthor_vm *vm , u32 slot_count );

return type is int, three args, no cap 🧚

πŸŽ€ ARGUMENTS πŸŽ€

  • exec β€” the locking/preparation context. it's giving "let me get my stuff in order first" energy.
  • vm β€” the VM that the GPU job is targeting. main character VM, honestly πŸ‘‘
  • slot_count β€” how many slots you wanna reserve. a number. a u32. respect it πŸ¦‹

πŸ’œ DESCRIPTION πŸ’œ

okay so here's the vibe πŸ”₯ β€” GPU jobs just assume that every BO bound to the VM at the time the job gets submitted will still be there when the job actually executes. bold of them, but go off i guess 😭

to guarantee that actually happens, we need to reserve a slot on all BOs mapped to a VM, and then update that slot with the job fence after its submission. that's the whole plan. no notes. periodt πŸ’…

⭐ RETURN ⭐

0 on success πŸŽ‰ β€” otherwise a negative error code, which is never the vibe but okay πŸ™ˆ
