Hi All, I'm currently working on a project for teaching driver development using virtual machines. We have developed in QEMU a virtual graphics adapter capable of a reasonable feature set. Note that because it's used in a teaching course, it is not very high-performance, as it is designed to look and act as close to a real device as possible (reasonable bit of overhead, and internally uses OSMesa). Currently it can do rasterize with T&L, texturing, bit-blits, and handle a subset of functionality needed for OpenGL (scissor, blend modes, etc.). Shader support is planned.
Currently we teach the course with the driver being written 100% from scratch as a character special device and writing user-space libraries manually. I'd like to move away from that, but I don't have any knowledge of newer mesa internals (including writing gallium drivers). Is there any documentation available to help, or if not, what would be the most basic implementations to look at in the source? Thanks, Christopher
