CXL CORE PCI(9)

💅 cxl core pci(9) 💅

okay so welcome to the Kernel API Manual, bestie — this is the page for cxl core pci, and it’s giving “small but essential.” Compute Express Link protocols are layered on top of PCIe — that’s the whole vibe. And CXL core provides a set of helpers for the CXL interactions that occur via PCIe. That’s it, that’s the lore. 💖

✨ SEE ALSO ✨

the Kernel file is ./drivers/cxl/core/pci.c, and the related-reference squad is literally right here:

• devm_cxl_add_dport_by_dev(9)
• cxl_hdm_decode_init(9)
• read_cdat_data(9)
• cxl_pci_get_latency(9)

no cap, keep these names exactly as they are — they’re the whole point. 🫶

so yeah, that’s the page, bestie. this one came from the source/version path ./drivers/cxl/core and is dated October 2026 — periodt. 🎀✨
