okay bestie, welcome to the cxl_probe_device_regs(9) page — yes, that's the manual name, and yes, we're in the Kernel API Manual. we're about to detect some CXL Device register blocks. it's giving low-level but make it cute. 🦋

🌸 NAME 🌸

cxl_probe_device_regs — Detect CXL Device register blocks 💖

✨ SYNOPSIS ✨

void cxl_probe_device_regs (struct device *dev , void __iomem *base ,
       struct cxl_device_reg_map *map );

literally the whole signature, bestie — copy it exactly, no cap. 🫶

🎀 ARGUMENTS 🎀

• dev — Host device of the base mapping. that's the main-character device, periodt. 👑
• base — Mapping of CXL 2.0 8.2.8 CXL Device Register Interface. yes, the whole 8.2.8 situation, iykyk. 🌀
• map — Map object describing the register block information found. it's not just a map, it's the map. 💅
