PUD(4) Device Drivers Manual PUD(4) NAME pud - Pass-to-Userspace Device SYNOPSIS pseudo-device pud pseudo-device putter DESCRIPTION The pud driver enables the implementation of block and character device drivers as userspace daemons. The daemons register the device major number they wish to handle. Registering a character device is mandatory, supporting the block device interface for same major device is optional. The major number must be available, i.e. another driver must not be registered to handle the operation. After successful registration the userspace daemon is supposed to handle the driver methods the kernel passes down to it. SEE ALSO puffs(4), putter(9) BUGS This document is in a hit-in-the-head style obviously not even near complete. The subsystem lacks a puffs-style library that servers can be written against.
