💅 vme_master_request — a Kernel API Manual moment

okay so bestie, welcome to vme_master_request(9), straight out of the Kernel API Manual ✨ this is the glow-up page for requesting a VME master window resource, and honestly it's giving "let me reserve my little corner of the bus" energy 🎀

✨ NAME ✨

vme_master_request — request a VME master window resource. that's it, that's the whole vibe 🦋

🌸 SYNOPSIS 🌸

struct vme_resource * vme_master_request (struct vme_dev *vdev , u32
address , u32 cycle , u32 dwidth );

no cap, that's the exact signature — copy it character for character, she's iconic like that 💖

🎀 ARGUMENTS 🎀

  • vdev — pointer to the VME device struct vme_dev that got assigned to your driver instance. like, which device are we even talking about, bestie? this one 👑
  • address — the required VME address space, literally the space you're asking for.
  • cycle — the required VME data transfer cycle type. yes, the type of cycle, don't skip it 🙈
  • dwidth — the required VME data transfer width. width matters, always 🌈

🦋 DESCRIPTION 🦋

so what does she actually do? she requests use of a VME window resource — and not just any window, one that's capable of being set for the requested address space, the requested data transfer cycle, and the requested width 💅 all three at once. it's giving "matching energy" fr fr.

⭐ RETURN ⭐

  • pointer to VME resource on success 🫶
  • NULL on failure 😭
