STRUCT MAAR_CONFIG(9)

💖 struct maar_config — MAAR configuration data 💖

okay bestie, welcome to the Kernel API Manual — we're looking at the struct maar_config(9) page, and it's literally the config data for a pair of MAARs. Let's get into it 🫶

✨ SYNOPSIS ✨

       struct maar_config {
           phys_addr_t lower;
           phys_addr_t upper;
           unsigned attrs;
        };

🧚 Members 🧚

• lower — the lowest address that the MAAR pair will affect. It must be aligned to a 2^16 byte boundary. no cap, alignment is not optional here 💅
• upper — the highest address that the MAAR pair will affect. It must be aligned to one byte before a 2^16 byte boundary. yes, one byte before — that's the vibe 😭
• attrs — the accessibility attributes to program, eg. MIPS_MAAR_S. The MIPS_MAAR_VL attribute will automatically be set. so you don't have to do it yourself, iconic behavior honestly ✨

🌸 Description 🌸

This struct describes the configuration of a pair of Memory Accessibility Attribute Registers — applying attributes from attrs to the range of physical addresses from lower to upper inclusive. inclusive inclusive, bestie, both ends are in the range 💖
