* enable ARB_vertex_buffer_object for more dri driversRoland Scheidegger2007-03-131-0/+2
| | | | | | | ARB_vertex_buffer_object looks like a useful extension even for old chips. The drivers should not need any code to be able to use this extension since they just use mesa's vbo code anyway. Newly enabled for i810, mach64, mga, r128, radeon, savage, sis and unichrome.
* Fix/improve framebuffer object reference counting.Brian2007-03-061-1/+1
| | | | | | | Use _mesa_reference_framebuffer() and _mesa_unreference_framebuffer() functions to be sure reference counting is done correctly. Additional assertions are done too. Note _mesa_dereference_framebuffer() renamed to "unreference" as that's more accurate.

* In gl_texture_image, replace ImageStride with an ImageOffsets array.Brian Paul2006-05-201-95/+53
| | | | | | | | | 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 Romanick2005-07-281-3/+13
| | | | | | | | | | | | | | | | | | | | | | _glapi_add_entrypoint has been replaced by a new routine called _glapi_add_dispatch.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)
* Fixes the glXGetProcAddress portion of the interface. Most of the functionsIan Romanick2005-07-261-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...
* All elements of pre-DRI_NEW_INTERFACE_ONLY are removed. This allowsIan Romanick2005-07-241-23/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1,402 lines of code to be removed from Mesa (drivers and libGL). The big winner is dri_util.c. Primary changes are: 1. Remove all "deprecated" entry-points from the various structures in dri_interface.h. 2. Rename the remaining fields to removed "version numbers." So, bindContext3 becomes bindContext. Functions with "New" in the name (e.g., CreateNewContext) were *not* changed, but that is an option. Having "New" in the name is less annoying to me than having "3" in the name. 3. Remove all compatibility code that handles cases where the driver or the loader is too old to support the latest interfaces. 4. Append the API version to the __driCreateNewScreen function name. This is currently done by hand. In the future (i.e., the next time we make an incompatible change to the interface) we'll want to come up with a better way to do this. This prevents old loaders from being able to load new (incompatible) drivers. 5. Bump the API version to 20050722. All drivers (by way of dri_util.c) require this version. 6. All drivers are *required* to expose GLX_SGIX_fbconfig and GLX_OML_swap_method (or the moral equivalents). Support for these functions in implicit in the use of the "new" interface. 7. Some cases still exist that need to be compiled differently in a loader or core Mesa versus in a driver. These are identified by the define IN_DRI_DRIVER.
* remove common macros used in the span functions of most drivers from the ↵Roland Scheidegger2005-07-011-36/+1
| | | | individual drivers and put them in common code. It is still possible for a driver to define its own macros if it has special needs. This affects CLIPPIXEL, CLIPSPAN, HW_CLIPLOOP, HW_ENDCLIPLOOP, and for drivers using the spantmp2 template also GET_SRC_PTR and GET_DST_PTR.
* Replace add_newer_entrypoints (src/mesa/main/context.c) withIan Romanick2005-06-301-8/+14
| | | | | | | | | | | | | | | device-specific code. A new Python script (src/mesa/glapi/extension_helper.py) generates a list of all entry-points for all known extensions. Each driver the selects only the extensions that it needs and enables the via either driInitExtensions or driInitSingleExtension. This code has been compile-tested on a drivers, but has only been run-tested on mga and i915 (on i830 hardware). These changes were discussed at length on the mesa3d-dev mailing list. http://marc.theaimsgroup.com/?t=111947074700001&r=1&w=2

* Texturing fixes for Savage3D/MX/IX:Felix Kuehling2005-04-233-24/+240
| | | | | | | | | | | | | | | | | - force emitting texAddr when the texture image changed (flush caches) - set transparent texture color key to something improbable (couldn't find a way to disable it completely) - fixed texture environment modes GL_DECAL and GL_REPLACE - made texture environment mode GL_BLEND a software fallback - added two custom texture formats for promoting from GL_ALPHA to ARGB8888 and 4444. Since the hardware can't be made to ignore the RGB color components, set them to 1 instead of 0. This gives the correct results - disabled GL_EXT_texture_env_add on Savage3D/MX/IX - map both GL_CLAMP and GL_CLAMP_TO_EDGE to hardware mode "wrap". It doesn't match either mode exactly by the spec, so we should either fall back on both or none. I chose the latter. - fall back to software when s and t wrapping modes differ (hardware has only one bit for both)
