✨ NAME ✨

vme_master_set — sets up the configuration for your VME master window. that's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

int vme_master_set (struct vme_resource *resource , int enabled ,
unsigned long long vme_base , unsigned long long size , u32 aspace , u32
cycle , u32 dwidth );

look at her go 😭 seven whole parameters, she's serving function signature realness 👑

---

🦋 ARGUMENTS 🦋

• resource — pointer to the VME master resource. like, the actual thing you got from requesting it 💖
• enabled — the state you want the window configured to. yes queen, tell it what to be ✨
• vme_base — base address for the window. where it all starts fr fr
• size — size of the VME window. how much room she gets 🌈
• aspace — VME address space for the VME window. which space we're in, iykyk
• cycle — VME data transfer cycle type for the VME window. the type of cycle, very main character energy 💅
• dwidth — VME data transfer width for the VME window. how wide the data's traveling, no cap 🧚

💜 DESCRIPTION 💜

so basically: this sets the configuration for the VME master window you handed it. one job, and she does it 🎯

🔥 RETURN 🔥

• Zero on success — slay, we love a clean return 💖
• -EINVAL if the operation isn't supported on this device, or if you gave it an invalid resource, or if the attributes you passed are invalid (rude of you tbh 🙈)
• also, hardware specific errors may be returned on top of all that. so like, stay alert bestie 💀
