acpi_amd_wbrf_add_remove(9)

💅 acpi_amd_wbrf_add_remove(9) — kernel API manual, but make it make sense 🎀

okay bestie, so this one is from the Kernel API Manual, and it's literally about telling everyone which frequency band your device is out here using. adding it, removing it, the whole vibe. let's go ✨

---

🌸 NAME 🌸

acpi_amd_wbrf_add_remove — add or remove the frequency band the device is using

like, that's it. that's the whole job. add or remove, pick your fighter 💅

---

✨ SYNOPSIS ✨

int acpi_amd_wbrf_add_remove (struct device *dev , uint8_t action ,
struct wbrf_ranges_in_out *in );

no cap, three args, one int coming back at you 🫶

---

🎀 ARGUMENTS 🎀

• dev — device pointer. yes girl, the device pointer, the whole reason we're here 🦋
• action — remove or add the frequency band into bios 🔥 (that's a uint8_t, so keep it cute and small)
• in — input structure containing the frequency band the device is using. it's the struct wbrf_ranges_in_out *, iykyk 🍓

---

💖 DESCRIPTION 💖

so basically the whole point here is to broadcast to other consumers the frequency band the device starts to use. main character announcement energy, honestly 👑

underneath the surface — and this is the part people always miss — the information is cached into an internal buffer first. that buffer is the moment, the buffer is everything. then a notification is sent to all those registered consumers, so they can go retrieve that buffer and know the latest active frequency bands. literally a group chat push notification but for frequency bands 😭

and the bestie part? consumers that haven't yet been registered can still retrieve the information from the cache when they register. nothing gets lost, nobody gets left on read 💜

---

🔥 RETURN 🔥

0 for success add/remove wifi frequency band 🌈

returns a negative error code for failure 💀

okay that's the whole page, slay 💅 this one's served fresh from ./drivers/platform/x86/amd, dated October 2026, and it's a Kernel API Manual situation. go forth and add/remove those frequency bands, bestie, you're gonna ate 🎀✨🦋
