2007-10-29Refactor and fix core vblank supportJesse Barnes
Consolidate support for synchronizing to and retrieving vblank counters. Also fix the core vblank code to return monotonic MSC counters, which are required by some GLX extensions. Adding support for multiple pipes to a low level driver is fairly easy, the Intel 965 driver provides simple example code (see intel_buffers.c:intelWindowMoved()). The new code bumps the media stream counter extension version to 2 and adds a new getDrawableMSC callback. This callback takes a drawablePrivate pointer, which is used to calculate the MSC value seen by clients based on the actual vblank counter(s) returned from the kernel. The new drawable private fields are as follows: - vblSeq - used for tracking vblank counts for buffer swapping - vblFlags - flags (e.g. current pipe), updated by low level driver - msc_base - MSC counter from the last time the current pipe changed - vblank_base - kernel DRM vblank counter from the last time the pipe changed Using the above variables, the core vblank code (in vblank.c) can calculate a monotonic MSC value. The low level DRI drivers are responsible for updating the current pipe (by setting VBLANK_FLAG_SECONDARY for example in vblFlags) along with msc_base and vblank_base whenever the pipe associated with a given drawable changes (again, see intelWindowMoved for an example of this). Drivers should fill in the GetDrawableMSC DriverAPIRec field to point to driDrawableGetMSC32 and add code for pipe switching as outlined above to fully support the new scheme.

2006-09-12Removing some of r200 dependency, cleaning up code a bit,Jerome Glisse
and fixing a couple of warning. More cleanup and shuffle to come. I have tested this change they might broke things especialy with r300_texstate.c change (format_x doesn't seems to be use at all by r300).

2005-07-26Fixes the glXGetProcAddress portion of the interface. Most of the functionsIan Romanick
that are currently obtained via glXGetProcAddress and all of the XF86DRI functions are replaced with a funciton table. This table will be passed to __driCreateNewScreen. One of the functions in the table is getProcAddress. This allows some loaders to expose functionality not in all loaders. This will be immediatly used for glxEnableExtension (formerly known to drivers as __glXScrEnableExtension). libGL (and in the future libglx) expose this function so that drivers can enable GLX extensions. libEGL should exposed eglEnableExtension to enable EGL extensions. The same function cannot be used for both because the extensions have different names and (possibly) different semantics. Drivers can optionally use one, both, or neither. The key parts are in the __DRIinterfaceMethodsRec structure in dri_interface.h. A pointer to one of these structures is passed into __driCreateNewScreen. Because of this, the version of the API is bumped to 20050725. Since the previous version(s) were never in a release, their existance is erased. I was actually a little surprised by how much code this cuts from the drivers. A lot of glXGetProcAddress calls disappear, and a lot of version checks go with them. Nice. The one thing I'm not sure of is removing __glXInitialize. For some reason that function was in the glXGetProcAddress table, but *nothing* in the Mesa tree used it. Did something with DRI conf. use this function? It seems odd...
