vfio_ap_mdev_on_cfg_add(9) 🦋

okay bestie, welcome to the Kernel API Manual — this page is for vfio_ap_mdev_on_cfg_add, and it’s giving “keep those AP config bitmaps in sync” energy. no cap. 💅

✨ NAME ✨

vfio_ap_mdev_on_cfg_add — when adapters, domains, and control domains get added to the host AP configuration, this function responds by updating the bitmaps that say which adapters, domains, and control domains have been added. that way they can be hot plugged into the guest once the AP bus scan completes — see the vfio_ap_on_scan_complete function for that part. 🫶✨

🌸 SYNOPSIS 🌸

void vfio_ap_mdev_on_cfg_add (struct ap_config_info *cur_config_info ,
       struct ap_config_info *prev_config_info );

🎀 ARGUMENTS 🎀

• cur_config_info — the current AP configuration information 💖
• prev_config_info — the previous AP configuration information 🌸
