Sharpening the Intel Driver Focus
This week, we finished up our 2009 Q1 release of the Intel driver. Most of the effort for this quarter has been to stabilize the recent work, focusing on serious bugs and testing as many combinations as we could manage.
Mode Setting
1. User mode. The entire output side of the driver stack is in user mode; all of the output detection, monitor detection, EDID parsing etc. This has some significant limitations, the worst of which is that the kernel has no idea what’s going on.
2. Kernel mode. All of that code moves into the kernel, where it is exposed both as a part of the DRI interface and also through the frame buffer APIs for use by the fb console or any other frame buffer applications. Lots of benefits here.
Direct Rendering
1. None. In this mode, the system doesn’t support direct rendering at all.
