b43_radio_read(9)

💅 b43_radio_read(9) — like, the radio register one 🎀

okay so real talk, bestie: this is a page from the Kernel API Manual (the b43 wireless crew's corner of it, specifically) and it's about reading a radio register. Yes, the whole page. It's short. She's ✨*concise*✨. Let's get into it.

---

🌸 NAME 🌸

b43_radio_read — 16bit Radio register read access

That's it. That's the whole vibe. You read 16 bits out of a radio register. Iconic behavior honestly 👑

---

✨ SYNOPSIS ✨

u16 b43_radio_read (struct b43_wldev *dev , u16 reg );

So you hand her a dev and a reg, and she hands you back a u16. Give and take. Balance. Main character energy 🦋

---

🫶 ARGUMENTS 🫶

• dev — -- undescribed --
• reg — -- undescribed --

😭 not me having to tell you that the manpage literally says -- undescribed -- for both of these. I'm not gatekeeping, I promise — that's genuinely all it says. The docs looked at these two parameters and went "no thoughts, head empty" 💀 so like… no cap, that's the whole description. Zero elaboration. Both of them. dev is a struct b43_wldev * and reg is a u16 per the synopsis, and that's the entire story we have to work with.

💖 SEE ALSO 💖

okay this is the part where she ate and left no crumbs — the SEE ALSO section is long, and every single one of these is a real reference, so don't come for me if it's a lot 🍓

First up, the source file itself:

• Kernel file ./drivers/net/wireless/broadcom/b43/phy_common.h

and then the whole friend group, in this exact order, all of them (9):

• b43_interference_mitigation
• b43_txpwr_result
• b43_phy_operations
• b43_phy_allocate
• b43_phy_free
• b43_phy_init
• b43_phy_exit
• b43_has_hardware_pctl
• b43_phy_read
• b43_phy_write
• b43_phy_copy
• b43_phy_mask
• b43_phy_set
• b43_phy_maskset
• b43_radio_write
• b43_radio_mask
• b43_radio_set
• b43_radio_maskset
• b43_radio_wait_value
• b43_radio_lock
• b43_radio_unlock
• b43_phy_lock
• b43_phy_unlock
• b43_switch_channel
• b43_software_rfkill
• b43_phy_txpower_check
• b43_phy_txpower_check_flags
• b43_phy_shm_tssi_read

a couple of those are enums and one is a struct, and the manpage spells them out as enum b43_interference_mitigation(9), enum b43_txpwr_result(9), struct b43_phy_operations(9), and enum b43_phy_txpower_check_flags(9) — so if you go looking, look for those exact names, mwah 💋

ngl, b43_radio_read's besties really showed up for her. b43_radio_write is right there in the middle, as she should be — they're a matching set 🔥

🌈 a lil sign-off 🌈

and that's the page!! short, sweet, and absolutely refusing to describe its own arguments 🙈 it lives at ./drivers/net/wireless/broadco... (yes, truncated, yes that's how it's printed, don't @ me) and it's dated October 2026 — future queen behavior fr fr ⭐

go read some radio registers, bestie. 16 bits at a time. periodt 💜🧚
