💅 lbs_set_reg(9) 💅

okay bestie, so this is a page from the Kernel API Manual and it's literally all about lbs_set_reg — the little function that writes a MAC, a Baseband, or an RF register. one job, three registers, zero drama. let's get into it ✨

🌸 SYNOPSIS 🌸

int lbs_set_reg (struct lbs_private *priv , u16 reg , u16 offset , u32 value );

that's the whole vibe. int going in, int coming out, four args in the middle. periodt.

🎀 ARGUMENTS 🎀

  • priv — a pointer to struct lbs_private. yes queen, the private struct, hand it over 🫶
  • reg — the register command. it has to be one of exactly three things: CMD_MAC_REG_ACCESS, CMD_BBP_REG_ACCESS, or CMD_RF_REG_ACCESS. like a little trio of options, pick one 💅
  • offset — the byte offset of the register you're setting. like, which spot 📍
  • value — the actual value you're writing to the register at 'offset'. the payload, the main character of this whole operation 👑

⭐ RETURN ⭐

  • 0 on success — slay, it worked 💖
  • an error code on failure — not slay, but at least it tells you 😭

like, the whole wireless libertas crew showed up 🌈 literally an iconic lineup.

ngl the source path in the footer got cut off at ./drivers/net/wireless/marvell... so if you need the full thing, that's just how it was printed — not me being lazy bestie 💀

okay that's the page!! mwah 💋 — signed off from the ./drivers/net/wireless/marvell... source, dated October 2026, and the title on the tin is still lbs_set_reg(9). go write some registers, you gorgeous nerd 🧚‍♀️⭐
