• prompt: Userspace platform driver with generic irq and dynamic memory
• type: tristate
• depends on: CONFIG_HAS_DMA
• defined in drivers/uio/Kconfig
• found in Linux kernels: 3.8–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.11, 6.12-rc+HEAD

Help text

Platform driver for Userspace I/O devices, including generic interrupt handling code. Shared interrupts are not supported.

Memory regions can be specified with the same platform device resources as the UIO_PDRV drivers, but dynamic regions can also be specified. The number and size of these regions is static, but the memory allocation is not performed until the associated device file is opened. The memory is freed once the uio device is closed.

If you don't know what to do here, say N.
