💖 wcnss_ctrl_smd_callback(9) 💖

okay so bestie, you're reading the Kernel API Manual — welcome, pull up a chair, this one's a lil function with a big job 🦋

✨ NAME ✨

wcnss_ctrl_smd_callback — the handler that catches responses coming back from SMD 👑

🌸 SYNOPSIS 🌸

int wcnss_ctrl_smd_callback (struct rpmsg_device *rpdev , void *data ,
int count , void *priv , u32 addr );

🎀 ARGUMENTS 🎀

• rpdev — the remote processor message device pointer, aka the whole reason we know who's talking to us 💅
• data — pointer to the incoming data packet, the actual goods 📦
• count — size of the incoming data packet, so we know how much of the goods there are
• priv — unused. literally just vibing there 🙈
• addr — unused too. also just vibing. they're both fine, they're supporting characters 🫶

⭐ DESCRIPTION ⭐

Handles any incoming packets from the remote WCNSS_CTRL service. that's the whole job, no cap. every packet that shows up from that service gets caught right here — main character energy, honestly 😭✨

ngl this is the function that's just... there when the remote side replies. iconic behavior.
