The Linux kernel configuration item CONFIG_UIO : prompt: Userspace I/O drivers; type: tristate; depends on: CONFIG_MMU; defined in drivers/uio/Kconfig .

  • Userspace I/O (UIO) drivers and realtime kernels often meet each other, since both are frequently used on in Linux 2.6.23 and allows device drivers to be writ-.

  • Mar 12, 2017 UIO drivers • Userspace I/O (UIO) is a framework for userspace drivers that do not fit into the standard patterns • Typical use-cases include .

  • Apr 17, 2008 UIO (Userspace I/O). By Han. J. Koch. – This interface allows the ability to write the majority of a driver in userspace with only very shell.

  • Linux系统中一般的驱动设备都是运行在内核空间,而在用户空间用应用程序调用即可,而UIO则是将驱动的很少一部分运行在内核空间,而在用户空间实现驱动的绝大多数功能!使用UIO可以避免设备的驱动程序需要随着内核的更新而更新的问题.

  • Much of the documentation for SPDK talks about user space drivers, so it's driver to one of two special device drivers that come bundled with Linux - uio or vfio. Unfortunately, kernel drivers must be designed to handle I/O coming from lots .

New versions of the Linux kernel will support a special userspace driver model, but some technical pitfalls might limit the use of this interesting new feature.
