devm_cxl_add_classdev(9)

💖 NAME 💖

devm_cxl_add_classdev — add a CXL memory class-code device.

okay so this page is from the Kernel API Manual, and it's giving section 9 energy for devm_cxl_add_classdev(9). Bestie, we're adding a CXL memory class-code device, no cap. ✨

🌸 SYNOPSIS 🌸

struct cxl_memdev * devm_cxl_add_classdev (struct cxl_dev_state *cxlds
);

That's the whole signature, literally. 🫶

🎀 ARGUMENTS 🎀

• cxlds — the CXL device state you're associating with the memdev. That's the one, bestie. 💅

💅 DESCRIPTION 💅

When the call returns, the device will have had a chance to attach to the cxl_mem driver. But heads up: it may fail to attach if the CXL topology is not ready — that means hardware CXL link down, or software platform CXL root not attached. 😭

The parent of the resulting device and the devm context for allocations is cxlds->dev. Periodt.

🦋 SEE ALSO 🦋

Kernel file ./drivers/cxl/mem.c, plus cxl mem(9) and devm_cxl_probe_mem(9). Go read those if you want the full lore. 📚✨
