Subject[PATCH 0/5] Input: serio_raw - add monitor/replay debugging interface
Date
The serio_raw driver is designed to provide "raw access" to mice, keyboards
etc; thus, a driver accessing serio_raw may live entirely in userland.

However, serio_raw lacks testability. It is practically impossible to do
regression tests on changes to a serio_raw -based userland driver. On the other
hand, the kernel's input subsystem has good testability support. With the help
of tools like utouch-evemu, we may capture and replay input events for evdev
drivers in regression tests.

This patchset contains extensions to the serio_raw driver which add debugfs
entries for monitoring and replaying byte sequence between a userland driver
and device. These byte sequences can be used in regression tests of the
userland driver. This patchset closes the gap between serio_raw and the input
subsystem regarding testability.

This patchset is successfully applied on kernel version 3.3-rc2.
