okay so bestie, welcome to the Kernel API Manual ✨ — yes the title is literally truncated in the header, that's not a typo, that's just how it's saved, iykyk 🫶

🌸 NAME 🌸

imx_dsp_rproc_rx_tx_callback — the inbound mailbox message handler, aka the girl who answers the door when messages show up 📬💖

✨ SYNOPSIS ✨

void imx_dsp_rproc_rx_tx_callback (struct mbox_client *cl , void *data
);

it's giving "void function, two args, no return value, no drama" 💅

🎀 ARGUMENTS 🎀

  • cl — the mailbox client pointer, and it's the one used for requesting the mailbox channel 🦋 like, this is the connection, the link, the situationship between you and the mailbox, fr fr
  • data — the mailbox payload 💌 literally whatever the message came carrying

👑 DESCRIPTION 👑

okay so this handler gets invoked by the mailbox driver whenever a mailbox message is received — every single time, no cap 🔥

usually, the SUSPEND and RESUME related messages get handled right here in this function 🌈 like this is their home, this is their main character energy

and the other messages? bestie, those get handled by the remoteproc core — not here, not this function's problem, she delegates 💅✨

ngl it's lowkey a bouncer situation: SUSPEND and RESUME get into this function's VIP section, everyone else gets pointed at the remoteproc core 🙈

🦋 SEE ALSO 🦋
