USB DisplayLink driver
Implement a driver for a DisplayLink adapter pluggable into the HelenOS graphics stack.
- Details
-
Although HelenOS has its own compositing server, the number of supported graphical adapters is rather low. On PCs, the compositor still relies on kernel to properly initialize the GPU, on other platforms the support is even more rudimentary.
The goal of this ticket is to implement a driver for a USB DisplayLink adapter that would be pluggable to the graphics stack and to the device driver framework implemented in HelenOS. The driver should support at least proper mode setting (with optimal resolution detection) and unaccelerated graphics output. The driver should be also portable to any HelenOS platform that support the USB bus.
- What Gains and Benefits will this bring?
-
Implementing a driver for graphical output over USB would allow to use HelenOS graphical interface on any platform with USB support. This would improve the experience when using HelenOS GUI in general. It would also open space for experiments with multi-monitor setup in HelenOS.
- Difficulty
-
Medium
- Required skills
-
A successful applicant will have good skills of programming in the C language and the ability to survive in a non-standard non-POSIX environment. Previous experience with driver or graphics stack implementation would be beneficial.
