vfio_ap_mdev_cfg_add(9)

🌸 NAME 🌸

okay so bestie, welcome to vfio_ap_mdev_cfg_add(9) from the Kernel API Manual 💅 This function is literally here to store bitmaps specifying the adapters, domains and control domains that have been added to the host's AP configuration for each matrix mdev to which they are assigned. It's giving very specific bookkeeping, and honestly? iconic ✨

💅 SYNOPSIS 💅

void vfio_ap_mdev_cfg_add (unsigned long *apm_add , unsigned long
       *aqm_add , unsigned long *adm_add );

It's void, so there's no return value to catch — no cap 🫶

🎀 ARGUMENTS 🎀

• apm_add — a bitmap specifying the adapters that have been added to the AP configuration 🌈
• aqm_add — a bitmap specifying the domains that have been added to the AP configuration 🦋
• adm_add — a bitmap specifying the control domains that have been added to the AP configuration 💖
