isci_host_init(9)

okay so bestie, welcome to isci_host_init(9) from the Kernel API Manual ✨ — this is the page for the function that does the "(re-)initialize hardware and internal (private) state" thing. let's get into it 💅

🎀 NAME 🎀

isci_host_init — (re-)initialize hardware and internal (private) state.

✨ SYNOPSIS ✨

int isci_host_init (struct isci_host *ihost );

🌸 ARGUMENTS 🌸

• ihost — host to init. that's the whole argument, bestie 🫶

🦋 DESCRIPTION 🦋

okay so here's the vibe check: any public facing objects (like asd_sas_port, and asd_sas_phys), or one-time initialization objects like locks and waitqueues, are not touched 🙅‍♀️. not even a little. they are initialized in isci_host_alloc, so this function leaves them alone. periodt 💅

lowkey important: "not touched" means not touched — those objects and one-time init things are handled in isci_host_alloc, not here 😭
