💖 ipa_qmi_setup(9) 💖

okay so welcome to the Kernel API Manual entry for ipa_qmi_setup, bestie — this is the little setup function that gets QMI message exchange ready, and yes it's giving main character energy in the IPA world ✨

🌸 NAME 🌸

ipa_qmi_setup — Set up for QMI message exchange

🎀 SYNOPSIS 🎀

int ipa_qmi_setup (struct ipa *ipa );

🦋 ARGUMENTS 🦋

• ipa — IPA pointer

👑 DESCRIPTION 👑

So this one gets called at the very end of ipa_setup, and its whole job is to prepare for the exchange of QMI messages that perform a "handshake" between the AP and modem. No cap, that's the vibe.

When the modem QMI server announces its presence, an AP request message supplies operating parameters to be used to the modem, and the modem acknowledges receipt of those parameters. Literally a whole little back-and-forth moment.

Important bestie note: the modem will not touch the IPA hardware until this handshake is complete. Periodt.

And if the modem crashes (or shuts down), a new handshake begins when the modem's QMI server is started again. Like a fresh start, but make it QMI 💅
