CXL FEATURES(9)

💖 cxl features(9) 💖

okay bestie, welcome to the Kernel API Manual page for cxl features(9) — it’s short, it’s iconic, and it’s all about CXL features. 💅

So, CXL Features: a CXL device that includes a mailbox supports commands that allow listing, getting, and setting of optionally defined features — think memory sparing or post package sparing. Vendors may define custom features for the device. Slay. ✨

• Kernel file ./drivers/cxl/core/features.c
• devm_cxl_setup_features(9)

🫶 that’s the whole vibe — source/version is ./drivers/cxl/core, dated October 2026, and the page is cxl features(9). bye bestie 💖
