2008-03-31DRI interface changes and DRI2 direct rendering support.Kristian Høgsberg
Add DRI2 direct rendering support to libGL and add DRI2 client side protocol code. Extend the GLX 1.3 create drawable functions in glx_pbuffer.c to call into the DRI driver when possible. Introduce __DRIconfig, opaque struct that represents a DRI driver configuration. Get's rid of the open coded __GLcontextModes in the DRI driver interface and the context modes create and destroy functions that the loader was requires to provide. glcore.h is no longer part of the DRI driver interface. The DRI config is GL binding agnostic, that is, not specific to GLX, EGL or other bindings. The core API is now also an extension, and the driver exports a list of extensions as the symbol __driDriverExtensions, which the loader must dlsym() for. The list of extension will always include the DRI core extension, which allows creating and manipulating DRI screens, drawables and contexts. The DRI legacy extension, when available, provides alternative entry points for creating the DRI objects that work with the XF86DRI infrastructure. Change DRI2 client code to not use drm drawables or contexts. We never used drm_drawable_t's and the only use for drm_context_t was as a unique identifier when taking the lock. We now just allocate a unique lock ID out of the DRILock sarea block. Once we get rid of the lock entirely, we can drop this hack. Change the interface between dri_util.c and the drivers, so that the drivers now export the DriverAPI struct as driDriverAPI instead of the InitScreen entry point. This lets us avoid dlsym()'ing for the DRI2 init screen function to see if DRI2 is supported by the driver.
2008-02-29Use __DRIextension mechanism providing loader functionality to the driver.Kristian Høgsberg
Instead of passing in a fixed struct, the loader now passes in a list of __DRIextension structs, to advertise the functionality it can provide to the driver. Each extension is individually versioned and can be extended or phased out as the interface develops.
2008-02-25Remove GetMSC DriverAPI function.Kristian Høgsberg
The DriverAPI is internal to the DRI drivers and GetDrawableMSC obsoletes GetMSC. Also, since the DRI driver interface has not yet been released, just drop the getMSC function from the DRI interface instead using the ABI preserving version mechanism. Finally, using void pointer privates in the DRI interface is not allowed, always pass the actual types around (__DRIdrawable in this case) to enhance type safety and readability of the code.
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.

2007-10-11Move GLX_MESA_swap_frame_usage DRI entry points to the new mechanism.Kristian Høgsberg
2007-10-10Move swap_interval to new extension mechanism.Kristian Høgsberg
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.
2007-10-10Remove screenConfigs from __DRIscreen.Kristian Høgsberg
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.
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.
2006-12-12Bug 7260: mach64 texture memory mng cleanupGeorge Sapountzis
mach64 uses its own set of texture memory management routines which are buggy, running a second DRI client kills the first one. This patch ports mach64 code to the stock dri texture managment code.
2006-10-02Bugzilla 6242: [mach64] Use private DMA buffers (only)Felix Kuehling
https://bugs.freedesktop.org/show_bug.cgi?id=6242 Patch by George Sapountzis: https://bugs.freedesktop.org/attachment.cgi?id=6271 Update to new mach64 DRM 2.0.0 with private DMA buffers. Handle EAGAIN in mach64FireBlitLocked: call drmCommandWrite up to MACH64_TIMEOUT times when EAGAIN is returned. Also handle EAGAIN in mach64FlushVerticesLocked.

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).
2005-07-29Fix a == vs !- typo for glx_enable_extensionJon Smirl
2005-07-28glxEnableExtension is a platform-specific function exported by the loader.Ian Romanick
Therefore, drivers should not require it to run.
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.
2005-05-30Add the no_rast debug option to mach64. It shows that software fallbacks areEric Anholt
pretty broken.

2004-06-03kill __driRegisterExtensions(), none of the functions did anythingJon Smirl
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'.
