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.
2007-10-10Pull createNewScreen entry point into dri_util.c.Kristian Høgsberg
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.
2007-10-10Drop __DRInativeDisplay and pass in __DRIscreen pointers instead.Kristian Høgsberg
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.

2007-03-06Fix/improve framebuffer object reference counting.Brian
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.
2007-03-06fix for bug#10182Xiang, Haihao
call _mesa_dereference_framebuffer instead of _mesa_dereference_framebuffer in i810, i915, i915tex, i965 drivers.

2005-08-18Make sure extension entry point offsets are properly initialized. This isIan Romanick
primarilly needed to support functions that are internally implemented using extension entry points (e.g., glBlendFunc uses glBlendFuncSeparate).
2005-08-15Add Egberts fixes for 64bit architecturesAlan Hourihane
Add additional checks for the *DRIRec info structure passed in from the device driver. This ensures that things fallback to indirect rendering if the DDX driver has had modifications (i.e. removal of the drmAddress field).
2005-07-28Major rip-up of internal function insertion interface. The oldIan Romanick
_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)
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...
2005-07-24All elements of pre-DRI_NEW_INTERFACE_ONLY are removed. This allowsIan Romanick
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.

2004-07-04Patch removes _SOLO definition needed for mesa-solo. mesa-soloJon Smirl
uses the NEW_INTERFACE now so _SOLO isn't necessary anymore. Tested with the hardware that I own.
2004-06-07The required DDX and DRI version numbers were switched. This went unnoticedIan Romanick
on several drivers (i.e., R200, Radeon, R128, Unichrome) becuase the required DRI and DDX versions were 4.0.0. Mach64 was already fixed.

2004-06-02driCheckDriDdxDrmVersion uses a function that is not available toIan Romanick
drivers when DRI_NEW_INTERFACE_ONLY is defined. #ifndef it away in that situation. Add a new function, driCheckDriDdxDrmVersion2, that is passed in the version information that is already supplied to __driCreateNewScreen. Part of the reason that information is supplied to __driCreateNewScreen is so that the driver doesn't have to make those calls to get it! Modify all drivers that support the new interface to use the new function instead of the old. As soon as all drivers support the new interface, driCheckDriDdxDrmVersion can be removed.
2004-06-01Fix dumb mistake from a previous commit. __driCreateScreen is nowIan Romanick
properly block with '#ifndef DRI_NEW_INTERFACE_ONLY'.
2004-06-01Convert 'Display *' to '__DRInativeDisplay *'. Only portions of theIan Romanick
interface that are not *strictly* part of the old interface were changed. Replace GetDrawableInfo type (dri_util.h) with PFNGLXGETDRAWABLEINFOPROC (dri_interface.h). Wrap __driCreateScreen (in drivers that use the new interface) with '#ifndef DRI_NEW_INTERFACE_ONLY'.
