💅 PHY_QueryBBReg_8723B(9) — the Kernel API Manual page, bestie edition 💅

okay so this is a page from the Kernel API Manual and it's about one (1) little function called PHY_QueryBBReg_8723B. she reads specific bits out of a BB register. that's it. that's her whole thing. and honestly? iconic.

✨ NAME ✨

PHY_QueryBBReg_8723B — read "specific bits" from a BB register 🎀

🌸 SYNOPSIS 🌸

u32 PHY_QueryBBReg_8723B (struct adapter *Adapter , u32 RegAddr , u32
BitMask );

so she takes an Adapter, a RegAddr, and a BitMask, and she hands you back a u32. the way that she is literally just three args and a dream 😭

🦋 ARGUMENTS 🦋

• Adapter — the adapter. that's the whole description, bestie, the page does not elaborate 🙈 she's mysterious like that. iykyk.
• RegAddr — the target address to be readback. this is the address you're reading from, periodt.
• BitMask — the target bit position in the target address to be readback. so like, where in that address the bits you want are chilling. lowkey the most important one ngl.

the readback register value ✨ that's the whole return. you get the value back. slay.
