2007-10-30More vblank cleanups.Michel Dänzer
* Fix crash at context creation in most drivers supporting vblank. * Don't pass vblank sequence or flags to functions that get passed the drawable private already. * Attempt to initialize vblank related drawable private fields just once per drawable. May need more work in some drivers.
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.

2006-10-18Want to stop passing x/y/width/height to Clear() function.Brian Paul
The coordinates need to be computed after we've got the hw lock. Code updated to: 1. Ignore all/x/y/width/height/ params passed to Clear func. 2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.
2005-10-27Bug #1028: Add hardware-accelerated stencil support to r128. Testing withEric Anholt
stencilwrap reported many issues with various modes. Some of these were complicated by the fact that spans are broken (Bug #1615), but some appear to be real bugs. However, while spans remain broken, I found that visual results were better by avoiding fallbacks rather than avoiding just a broken stencil implementation. Note that this required changing the depth spans at 24+8bpp into read-modify-write cycles. It would be nicer as a single write with a mask, but the kernel span blits turn off masking.

2004-01-20Before calling _mesa_create_context(), initialize a dd_function_table structBrian Paul
by calling _mesa_init_driver_functions() and then plugging in the driver- specific functions. In particular, make sure ctx->Driver.NewTextureObject points to the appropriate driver function so that _all_ texture objects are augmented with the driver-specific data. Put in a bunch of assertions in the texture-related driver functions that texObj->DriverData is valid. Remove old dead code in near future.
