STRUCT CXL_EP(9)

✨ NAME ✨

okay bestie, struct cxl_ep is literally here to track an endpoint's interest in a port. this is the struct cxl_ep(9) page from the Kernel API Manual, and it's giving “small struct, important job” energy 💅✨

🦋 SYNOPSIS 🦋

struct cxl_ep {
    struct device *ep;
    struct cxl_dport *dport;
    struct cxl_port *next;
 };

💖 Members 💖

• ep — the device that hosts a generic CXL endpoint (expander or accelerator). main-character device energy, no cap 🫶
• dport — which dport routes to this endpoint on port. yes, it's routing lore 🌈
• next — the cxl switch port across the link attached to dport; it's NULL if attached to an endpoint. that's the whole link situation, periodt 💀
