CXL OBJECTS(9)

💅 CXL OBJECTS 💅

okay so you're in the Kernel API Manual, section 9, and this page is literally just the glow-up reveal of the CXL core objects — ports, decoders, and regions — no cap. 🎀

The tea ☕: these iconic little objects are shared between the subsystem drivers cxl_acpi, cxl_pci, and the core drivers (port-driver, region-driver, nvdimm object-drivers... etc). Like, they all pass the aux cord around, iykyk. 🫶
