VHOST_SET_FORK_FROM_OWNER(9)

🦋 NAME 🦋

okay so this is the Kernel API Manual page for VHOST_SET_FORK_FROM_OWNER(9) — the icon that sets the fork_owner flag for the vhost device. This ioctl must be called before VHOST_SET_OWNER. Only available when CONFIG_VHOST_ENABLE_FORK_OWNER_CONTROL=y. ✨

✨ SYNOPSIS ✨

the whole synopsis is literally just this, bestie:

VHOST_SET_FORK_FROM_OWNER

💅 DESCRIPTION 💅

so the param is fork_owner: an 8-bit value that determines the vhost thread mode. this is the main character setting for how vhost workers get made 👑

• When fork_owner is set to VHOST_FORK_OWNER_TASK (the default value):
  • Vhost will create vhost worker as tasks forked from the owner, inheriting all of the owner's attributes. 🫶
• When fork_owner is set to VHOST_FORK_OWNER_KTHREAD:
  • Vhost will create vhost workers as kernel threads. 🧵
