STM32_PERIPHERAL_FIREWALL(9)

💅 STM32_PERIPHERAL_FIREWALL(9)

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's a lil guy, but it's lowkey important, so let's get into it ✨

🌸 NAME 🌸

So this page is all about the firewall types, and there's three of them. Yes, three. Not me hyping up a whole trio 🫶

• STM32_PERIPHERAL_FIREWALL — this type of firewall protects peripherals 💖
• STM32_MEMORY_FIREWALL — this type of firewall protects memories/subsets of memory zones 🧠✨
• STM32_NOTYPE_FIREWALL — undefined firewall type 💀 (like, it's literally the "we don't know" one, no cap)

fr fr, STM32_NOTYPE_FIREWALL being undefined is the whole point — it's not a mistake, it's just the not-a-type type 🙈

⭐ SYNOPSIS ⭐

STM32_PERIPHERAL_FIREWALL

that's it. that's the synopsis. she's minimal, she's iconic 👑

🦋 SEE ALSO 🦋

go look at the kernel file ./include/linux/bus/stm32_firewall.h — specifically the struct in there 👀 that's where the real tea is 🍓

and then these besties, in no particular order (okay, fine, this order):

• stm32_firewall_controller(9)
• stm32_firewall_controller_register(9)
• stm32_firewall_controller_unregister(9)
• stm32_firewall_populate_bus(9)

like, if this page was a vibe check, those are the main characters 🌈

💜 mwah, that's the whole page. short and slay.

sign-off szn: this lil beauty lives in ./include/linux/bus, dated October 2026, and it's page STM32_PERIPHERAL_FIREWALL(9) of the Kernel API Manual 🎀✨ go forth and firewall responsibly bestie 💅🔥
