* Refactor and fix core vblank supportJesse Barnes2007-10-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Pull createNewScreen entry point into dri_util.c.Kristian Høgsberg2007-10-101-53/+33
| | | | | | | | This pulls the top level createNewScreen entry point out of the drivers and rewrites __driUtilCreateNewScreen in dri_util.c to be the new entry point. The change moves more logic into the common/ layer and changes the createNewScreen entry point to only be defined in one place.
* Remove screenConfigs from __DRIscreen.Kristian Høgsberg2007-10-101-2/+1
| | | | | | | | | | | | The screenConfigs field of __DRIscreen points back to the containing __GLXscreenConfigs struct. This is a serious abstraction violation; it assumes that the loader is libGL and that there *is* a __GLXscreenConfigs type in the loader. Using the containerOf macro, we can get from the __DRIscreen pointer to the containing __GLXscreenConfigs struct, at a place in the stack where the above is a valid assumption. Besides, the __DRI* structs shouldn't hold state other than the private pointer.
* Drop __DRInativeDisplay and pass in __DRIscreen pointers instead.Kristian Høgsberg2007-10-101-11/+11
| | | | | | | | | | | | | Many DRI entry points took a __DRInativeDisplay pointer and a screen index as arguments. The only use for the native display pointer was to pass it back to the loader when looking up the __DRIscreen for the given screen index. Instead, let's just pass in the __DRIscreen pointer directly, which let's drop the __DRInativeDisplay type and the getScreen function. The assumption is now that the loader will be able to retrieve context from the __DRIscreen pointer when necessary.

* Remove ctx->Point._Size and ctx->Line._Width.Brian2007-07-211-1/+1
| | | | | | The clamping for these values depends on whether we're drawing AA or non-AA points, lines. Defer clamping until drawing time. Drivers could compute and keep clamped AA and clamped non-AA values if desired.
* Overhaul/simplify SWvertex and SWspan attribute handling.Brian2007-05-201-8/+8
| | | | | Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.

| * Enable GLX_SGI_make_current_read for tdfx.Ian Romanick2006-11-146-30/+64
| | | | | | | | | | | | | | | | | | Implement GLX_SGI_make_current_read for tdfx. Remove annoying debug printf in tdfxSwapBuffers. Updated a comment in drirenderbuffer.h to note that the tdfx driver uses a flag that was previously only used by s3v. This code was tested with glxgears, wincopy, and manywin.

| * tdfxDDWriteDepthPixels can be called with mask == NULL.Ian Romanick2006-11-131-2/+2
| | | | | | | | | | | | | | Via depth_test_pixels (swrast/s_depth.c), tdfxDDWriteDepthPixels can be called with mask == NULL. Test for this condition in the places where mask might be dereference. This matches the behavior of several other functions in this file with a 'const GLubyte mask[]' parameter.

| | | | | | | | | | | | | | In 16-bit color modes the 3D driver was erroneously creating fbconfigs with 16-bits of accumulation alpha. Since the 2D driver always generates modes with zero bits of alpha, the lists of fbconfigs did not match and warnings were generated by libGL.

* In gl_texture_image, replace ImageStride with an ImageOffsets array.Brian Paul2006-05-201-18/+20
| | | | | | | | | Some hardware lays out 3D mipmaps in a manner that can't be expressed with a simple image stride. The ImageOffsets array is allocated and initialized to typical defaults in the _mesa_init_teximage_fields() function. If needed, a driver will then have to replace these offsets. TexStore and TexelFetch routines updated to use offsets array.

* Major rip-up of internal function insertion interface. The oldmesa_6_3_1Ian Romanick2005-07-282-3/+17
| | | | | | | | | | | | | | | | | | | | | | _glapi_add_entrypoint has been replaced by a new routine called _glapi_add_dispatch. This new routine dynamically assignes dispatch offsets to functions added. This allows IHVs to add support for extension functions that do not have assigned dispatch offsets. It also means that a driver has no idea what offset will be assigned to a function. The vast majority of the changes in this commit account for that. An additional table, driDispatchRemapTable, is added. Functions not in the Linux OpenGL ABI (i.e., anything not in GL 1.2 + ARB_multitexture) has a fixed offset in this new table. The entry in this table specifies the offset in of the function in the real dispatch table. The internal interface was also bumped from version 20050725 to 20050727. This has been tested with various programs in progs/demos on: radeon (Radeon Mobility M6) r128 (Rage 128 Pro) mga (G400)
