✨ devm_nvdimm_memremap ✨

Okay bestie, welcome to the Kernel API Manual corner 🫶 — today’s main character is devm_nvdimm_memremap.

💖 NAME 💖

devm_nvdimm_memremap — map a resource that is shared across regions. That’s the whole vibe: shared mapping, and the device gets a reference to it. Periodt. 💅

🦋 SYNOPSIS 🦋

void * devm_nvdimm_memremap (struct device *dev , resource_size_t offset , size_t size , unsigned long flags );

🎀 ARGUMENTS 🎀

• dev — the device that will own a reference to the shared mapping. She’s holding the ref, okay? 👑
• offset — physical base address of the mapping.
• size — mapping size.
• flags — memremap flags, or, if zero, perform an ioremap instead. Yep, zero flips it to the ioremap route — iconic little plot twist 🌸
