💖 ipa_mem_setup(9) — kernel API manual, but make it cute 💖

okay so bestie, welcome to the glow-up era of ipa_mem_setup(9) — this is a page from the Kernel API Manual, and it's giving "niche networking lore that actually slays." let's get into it 🎀

✨ NAME ✨

ipa_mem_setup — Set up IPA AP and modem shared memory areas 🫶

🌸 SYNOPSIS 🌸

int ipa_mem_setup (struct ipa *ipa );

🦋 ARGUMENTS 🦋

  • ipa — IPA pointer. that's it. that's the whole argument. she's lowkey simple like that 💅

💜 DESCRIPTION 💜

okay so here's the vibe: this function sets up the shared memory regions in IPA local memory. sounds fancy but fr fr it's two things — zero-filling memory regions, and in the case of header memory, telling the IPA where it's located. iconic behavior honestly ✨

this function performs the initial setup of this memory. and ngl, if the modem crashes? its regions get re-zeroed in ipa_mem_zero_modem. so cleanup exists, just not here, iykyk 💀

the AP informs the modem where its portions of memory are located in a QMI exchange that occurs at modem startup. main character communication energy 👑

and here's the thing that matters: there is no need for a matching ipa_mem_teardown function. no teardown era. the setup ate and left no crumbs. periodt 🌈

🍓 RETURN 🍓

0 if successful, or a negative error code. negative error code = not the vibe 😭
