💾 bcm47xx_nvram_copy(9) — the Kernel API Manual tea ☕

okay so bestie, welcome to the Kernel API Manual entry for bcm47xx_nvram_copy(9) and honestly? It's a short one. Grab a boba, this'll be quick 🧋✨

🌸 NAME 🌸

bcm47xx_nvram_copy — copy NVRAM to internal buffer 💅

like, that's it. that's the whole job. it copies the NVRAM into an internal buffer. iconic minimalism, no notes 👑

---

✨ SYNOPSIS ✨

void bcm47xx_nvram_copy (void __iomem *nvram_start , size_t res_size );

returns void, takes two args, gets straight to business 🫶

---

🎀 ARGUMENTS 🎀

• nvram_start — so the manpage literally just says -- undescribed -- 😭 bestie the docs simply did not show up for this one. it's a void __iomem * pointer, and that's all the page is giving us. no cap, that's the whole description.
• res_size — also -- undescribed -- 🙈 a size_t with zero lore attached. we know its name and its type and literally nothing else. iykyk, and apparently we do not know 💀

ngl, the source is gonna be your bestie here — the manual page is leaving these two on read 🫠
