Initially it's mostly based on Zack Rusin's composite / video work for the Xorg state tracker. The motivation behind this state tracker is that the Xorg state tracker has a number of interfaces to work with: 1) The Xorg sdk (versioned) 2) Gallium3D (not versioned) 3) KMS modesetting (versioned) 4) Driver-private (hopefully versioned) Since Gallium3D is not versioned, the Xorg state tracker needs to be compiled with Gallium, but it's really beneficial to be able to compile xorg drivers standalone. Therefore the xa state tracker is intended to supply the following functionality: 1) Versioning. 2) Surface functionality (creation and copying for a basic dri2 implementation) 3) YUV blits for textured Xv. 4) Solid fills without ROP functionality. 5) Copies with format conversion and - reinterpretation but without ROP 6) Xrender- type compositing for general acceleration. The first user will be the vmwgfx xorg driver. When there are more users, we need to be able to load the appropriate gallium pipe driver, and we should investigate sharing the loadig mechanism with the EGL state tracker. IMPORTANT: Version compatibilities: While this library remains OUTSIDE any mesa release branch, and the major version number is still 0. Any minor bump should be viewed as an incompatibility event, and any user of this library should test for that and refuse to use the library if minor versions differ. As soon as the library enters a mesa release branch, if not earlier, major will be bumped to 1, and normal incompatibility rules (major bump) will be followed. It is allowed to add function interfaces while only bumping minor. Any user that uses these function interfaces must therefore use lazy symbol lookups and test minor for compatibility before using such a function. |
