💅 brcmf_sdiod_sglist_rw(9) — bestie, let's talk block data 💅

okay so first things first: this page lives in the Kernel API Manual, and it's all about brcmf_sdiod_sglist_rw, the SDIO interface function that handles block data access. yes, that's a lot of letters, no, you're not supposed to say it out loud. 🫶

✨ NAME ✨

brcmf_sdiod_sglist_rw — the SDIO interface function for block data access. that's it, that's the vibe. 🎀

---

🌸 SYNOPSIS 🌸

int brcmf_sdiod_sglist_rw (struct brcmf_sdio_dev *sdiodev , struct
sdio_func *func , bool write , u32 addr , struct sk_buff_head *pktlist
);

like, look at that signature. it's giving "five arguments and a dream." we stan a function with a clear type signature. ✨

🦋 ARGUMENTS 🦋

• sdiodev — the brcmfmac sdio device. this is the main character of the hardware side, iykyk. 👑
• func — the SDIO function. yes, the actual function, not this function, don't get it twisted bestie.
• write — the direction flag. it tells you which way the data's flowing, lowkey the most important little boolean in the room.
• addr — the dongle memory address, used as either the source or the destination. depends on which way you're going, fr fr.
• pktlist — the skb buffer head pointer. that's your packet list, your whole squad of buffers. 🍓

💖 DESCRIPTION 💖

so here's the tea: this function is the interface function to the MMC stack for block data access. it takes on that responsibility so you don't have to, and honestly? iconic. 🌈

one thing though, and this is important — it assumes that the skb passed down by the caller has already been padded and aligned. so like, do your homework before you call it. it's not gonna pad or align anything for you, bestie. that's on you. 💀

no cap: if you hand it an unpadded or unaligned skb, that's not a this-function problem, that's a you problem. get your buffers aligned first. 💅
