okay bestie, welcome to the Kernel API Manual entry for vtpmx_ioc_new_dev(9) — it's the handler for the %VTPM_PROXY_IOC_NEW_DEV ioctl, and we're gonna vibe-check it together. no cap. 💅

✨ NAME ✨

vtpmx_ioc_new_dev — handler for the %VTPM_PROXY_IOC_NEW_DEV ioctl

🦋 SYNOPSIS 🦋

long vtpmx_ioc_new_dev (struct file *file , unsigned int ioctl ,
       unsigned long arg );

🌸 ARGUMENTS 🌸

• file — /dev/vtpmx
• ioctl — the ioctl number
• arg — pointer to the struct vtpmx_proxy_new_dev

💖 DESCRIPTION 💖

okay so picture this: vtpmx_ioc_new_dev creates an anonymous file, and that anonymous file is used by the process acting as a TPM to communicate with the client processes. it also adds a new TPM device, and data is proxied through that device to this TPM acting process. the caller gets a file descriptor to communicate with the clients, plus the major and minor numbers for the TPM device. literally the whole handoff, periodt. ✨
