STRUCT NVMEM_KEEPOUT(9)

💖 struct nvmem_keepout(9) — the Kernel API Manual, but make it group chat 💖

okay so bestie, this page lives in the Kernel API Manual and it's all about struct nvmem_keepout — literally the NVMEM register keepout range ✨ like, the little "do not touch" zone of your NVMEM. iykyk 🫶

🌸 NAME 🌸

struct nvmem_keepout — NVMEM register keepout range. no cap, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

struct nvmem_keepout {
    unsigned int start;
    unsigned int end;
    unsigned char value;
 };

look at her. three fields. main character energy 💅

• start — the first byte offset to avoid. like, this is where the "nope, not this one" begins 🚫
• end — one beyond the last byte offset to avoid. yes bestie, one beyond — it's exclusive, so the last byte you actually avoid is end - 1. do not come for me, that's just how it is 💀
• value — the byte to fill reads with for this region. so when somebody reads this zone, they get this byte back instead of whatever spicy secret is actually there 🙈
