STRUCT OMAP_IOMMU_DOMAIN(9)

💖 struct omap_iommu_domain(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is struct omap_iommu_domain, which is literally, as the name suggests, an omap iommu domain 🎀. that's it. that's the vibe.

🌸 NAME 🌸

struct omap_iommu_domain — omap iommu domain 🦋

✨ SYNOPSIS ✨

here's the whole glow-up, copied exactly, no cap:

struct omap_iommu_domain {
    u32 num_iommus;
    struct omap_iommu_device *iommus;
    struct device *dev;
    spinlock_t lock;
    struct iommu_domain domain;
 };

👑 Members 👑

• num_iommus — the count of iommus chilling in this domain. literally just a number, u32 coded 💅
• iommus — the omap iommu device data for all the iommus in this domain. everyone's invited to the party 🫶
• dev — the struct device that's using this domain. the one actually living here 🏠
• lock — the domain spinlock_t, and bestie listen: you should take it when attaching/detaching. not optional, not a suggestion, fr fr 🔒
• domain — the generic domain handle that the iommu core code uses. it's giving "behind the scenes manager" energy 💀
