ipa_uc_power(9)

💖 NAME 💖

ipa_uc_power — Take a proxy power reference for the microcontroller 💅

and yes bestie, this is the ipa_uc_power(9) page from the Kernel API Manual 🫶

✨ SYNOPSIS ✨

void ipa_uc_power (struct ipa *ipa );

🎀 ARGUMENTS 🎀

• ipa — IPA pointer. That's the whole argument list, iconic behavior honestly ✨

🦋 DESCRIPTION 🦋

okay so picture this: the first time the modem boots, it loads firmware for and starts the IPA-resident microcontroller. The microcontroller signals that it has completed its initialization by sending an INIT_COMPLETED response message to the AP.

The AP must ensure the IPA is powered until it receives this message, and to do so we take a "proxy" clock reference on its behalf here, bestie. Once we receive the INIT_COMPLETED message — specifically in ipa_uc_response_hdlr — we drop this power reference. periodt 💅
