💖 fsl_mc_portal_allocate(9) 💖

okay bestie, welcome to the Kernel API Manual page for fsl_mc_portal_allocate(9) — yes, the manual name is folded in right here because we are not copying the header line, we are living it ✨

💖 NAME 💖

fsl_mc_portal_allocate - Allocates an MC portal. that's the whole name, no cap 💅

✨ SYNOPSIS ✨

int fsl_mc_portal_allocate (struct fsl_mc_device *mc_dev , u16
       mc_io_flags , struct fsl_mc_io **new_mc_io );

🎀 ARGUMENTS 🎀

• mc_dev — MC device for which the MC portal is to be allocated. like, the device that's getting its portal moment 💅
• mc_io_flags — Flags for the fsl_mc_io object that wraps the allocated MC portal. flags for the wrapper, because the wrapper matters too 🫶
• new_mc_io — Pointer to area where the pointer to the fsl_mc_io object that wraps the allocated MC portal is to be returned. yes, a pointer to an area where a pointer gets returned — pointerception, but make it slay 😭

🦋 DESCRIPTION 🦋

okay so here's the tea: this function allocates an MC portal from the device's parent DPRC, from the corresponding MC bus' pool of MC portals and wraps it in a new fsl_mc_io object. iconic behavior, honestly.

and if 'mc_dev' is a DPRC itself, the portal is allocated from its own MC bus. periodt. that's the whole description, no extra lore added by me 🌸
