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 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. + +and coming up: +4) Solid fills with ROP functionality. +5) Copies with ROP functionality, format conversion and - reinterpretation. +6) Xrender- type compositing for general acceleration. + +4-6 is not implemented yet since they are not directly used by the +vmwgfx driver. + +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. + diff --git a/src/gallium/state_trackers/xa/xa-indent b/src/gallium/state_trackers/xa/xa-indent new file mode 100755 index 00000000000..1972e53226f --- /dev/null +++ b/src/gallium/state_trackers/xa/xa-indent @@ -0,0 +1,3 @@ +# +indent --linux-style -i4 -ip4 -bad -bap -psl $* + diff --git a/src/gallium/state_trackers/xa/xa_context.c b/src/gallium/state_trackers/xa/xa_context.c new file mode 100644 index 00000000000..5ac16a2b195 --- /dev/null +++ b/src/gallium/state_trackers/xa/xa_context.c @@ -0,0 +1,258 @@ +/********************************************************** + * Copyright 2009-2011 VMware, Inc.
