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.
Che-Liang Chiou (5): Input: serio_raw - return proper result when serio_raw_read fails Input: serio_raw - extract queue interface Input: serio_raw - factor out common pattern of write Input: serio_raw - add debugfs interface Input: serio_raw - implement debugfs interface
