2009-10-23glapi: Always build libglapi.a.Chia-I Wu
This is made possible by making glapioffsets.h and glapidispatch.h internal headers of glapi. They should only be included indirectly through dispatch.h by mesa. Signed-off-by: Chia-I Wu <olvaffe@gmail.com>
2009-09-08mesa: Add support for ARB_draw_elements_base_vertex.Eric Anholt
2009-09-01mesa: Make MultiDrawElements submit multiple primitives at once.Eric Anholt
Previously, MultiDrawElements just called DrawElements a bunch of times. By sending several primitives down the pipeline at once, we avoid a bunch of validation. On my GL demo, this improves fps by 2.5% (+/- .41%) and reduces CPU usage by 70.5% (+/- 2.9%) (n=3). Reviewed by: Ian Romanick <ian.d.romanick@intel.com>

2006-04-25Put color index attribute into the 6th attribute slot.Brian Paul
Update a lot of loops, conditionals to use the _TNL_FIRST/LAST_* values instead of specific vertex attributes. Remove the EdgeFlagv function from the GLvertexformat struct.
2005-08-05Fix recent problems with display lists and other parts of the code.Ian Romanick
CALL_by_offset, SET_by_offset, and GET_by_offset all had various problems. The core issue is that parts of the device-independent code in Mesa assumes that all functions have slots in the dispatch table. This is especially true in the display list code. It will merrilly try to set dispatch pointers for glVertexAttrib1fARB even if GL_ARB_vertex_program is not supported. When the GET/SET/CALL macros are invoked, they would read a 0 from the remap table. The problem is that 0 is the dispatch offset for glNewList! One change is that the remap table is now initialized to be full of -1 values. In addtion, all of the *_by_offset marcos misbehave in an obvious way if the specified offset is -1. SET_by_offset will do nothing, GET_by_offset will return NULL, and CALL_by_offset, since it uses GET_by_offset, will segfault. I also had to add GL_EXT_blend_func_separate to the list of default extensions in all_mesa_extensions (src/mesa/drivers/dri/common/utils.c). Even though many drivers do not export this extension, glBlendFunc is internally implemented by calling glBlendFuncSeparate. Without this addition, glBlendFunc stopped working on drivers (such as mga) that do not export GL_EXT_blend_func_separate. There are still a few assertions / crashes in GL_ARB_vertex_program tests, but I don't think that these are related to any of my changes.
2005-07-18Wrap every place that accesses a dispatch table with a macro. A new script-Ian Romanick
generated file, called src/mesa/glapi/dispatch.h, is added. This file contains three macros for each API function. It contains a GET, a SET, and a CALL. Each of the macros take a pointer to the context and a pointer to the dispatch table. In several threads on mesa3d-dev we discussed replacing _glapi_add_entrypoint with a new function called _glapi_add_dispatch. For this discussion, the important difference between the two is that the caller of _glapi_add_dispatch does *not* know what the dispatch offset will be at compile time. Because of this callers need to track the dispatch offset returned by _glapi_add_dispatch. http://marc.theaimsgroup.com/?t=111947074700001&r=1&w=2 The downside is that driver code then has to access the dispatch table two different ways. It accesses it using structure tags (e.g., exec->Begin) for functions with fixed offsets and via a remap table (e.g., exec[ remap->NewExtensionFunction ]) for functions without fixed offsets. Yuck! Using the macros allows both types of functions to be accessed identically. If a driver needs to set a pointer for Begin, it does 'SET_Begin(ctx, exec, my_begin_function)'. If it needs to set a pointer for NewExtensionFunction, it does 'SET_NewExtensionFunction(ctx, exec, my_NewExtensionFunction_function)'. Furthermore, if at some point in the future a static offset is assigned for NewExtensionFunction, only the macros need to change (instead of every single place that accesses a table for that function). This code differs slightly from the originally posted patches in that the CALL, GET, and SET marcos no longer take a context pointer as a parameter. Brian Paul had suggested that the remap table could be stored as a global since it would be set at CreateScreen time and would be constant for all contexts. This change reflects that feedback. http://marc.theaimsgroup.com/?t=112087194700001&r=1&w=2

alias with the corresponding ARB functions. GL_ARB_vertex_shader (and OpenGL 2.0's) VertexAttrib functions don't alias with conventional vertex attributes, as GL_NV_vertex_program does. So, the ARB and NV version of VertexAttrib need to be distinct.

2001-03-11Support for swappable tnl modules.Gareth Hughes
Core Mesa provides a neutral tnl module that verifies the currently module before installing the tnl function pointers in a lazy fashion. It also records which tnl functions have been swapped out, and only restores these when tnl modules themselves are swapped. Fallback strategies: Drivers set a bitmask of dangerous stage changes. When such a state change occurs, the driver should restore the neutral tnl module via _mesa_restore_exec_vtxfmt(). The neutral tnl module will call _mesa_update_state(), followed by ctx->Driver.ValidateTnlModule() if the validation bitmask matches the new state bitmask. The driver should call _tnl_wakeup_exec() if it can no longer handle the current state, which will revert to the default tnl module. In this case, previous vertices should be replayed as required (depending on the current primitive) after the new tnl module is installed. If the driver uses chooser functions for any part of the tnl module, these should generally be reinstalled as part of the fallback to the neutral tnl module. For example, if the lighting state changes, a driver might fall back to the neutral tnl module, verify that the current lighting state can be handled, and use the chooser function to pick the most efficient implementation of the current lighting state. It is up to the drivers to detect and handle fallback cases caused by tnl function calls themselves (such as glTexCoord4f* if the current tnl module can't handle projected textures, for example).
