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.
2008-01-06Replace gl_framebuffer's _ColorDrawBufferMask with _ColorDrawBufferIndexesBrian
Each array element is now a BUFFER_x token rather than a BUFFER_BIT_x bitmask. The number of active color buffers is specified by _NumColorDrawBuffers. This builds on the previous DrawBuffer changes and will help with drivers implementing GL_ARB_draw_buffers.
2007-12-22fix GL_LINE_LOOP with drivers using own render pipeline stage (#12410, #13527)Roland Scheidegger
primitive needs to include the begin/end flags (broken since vbo-0.2). Should fix missing first/last line segment on gamma, i810, i915, mga, r200, radeon, s3v, savage, unichrome (r300 already correct). Tested on r200, fixes #13527.
2007-10-30More vblank cleanups.Michel Dänzer
* Fix crash at context creation in most drivers supporting vblank. * Don't pass vblank sequence or flags to functions that get passed the drawable private already. * Attempt to initialize vblank related drawable private fields just once per drawable. May need more work in some drivers.
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.

2007-10-10Move 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.
2007-10-10Replace open-coded major, minor, and patch version fields with __DRIversionRec.Kristian Høgsberg
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 createDrawable and destroyDrawable fron DRIinterfaceMethods.Kristian Høgsberg
All the DRI driver did was call the createDrawable callback immediately upon entry to DRIscreen::createNewDrawable to get the drm_drawable_t. We can just call that before calling into the DRI driver and pass the returned drm_drawable_t as an argument to the DRI entry point. Likewise for destroyDrawable. Also, DRIdrawablePrivate::draw isn't used anywhere, and since the driver no longer needs the XID of the drawable we can now drop that.
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.
2007-07-21Remove ctx->Point._Size and ctx->Line._Width.Brian
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.
2007-04-16remove _tnl_arb_vertex_program_stageBrian
2007-03-30call DRI_VALIDATE_DRAWABLE_INFO(), bug 10477Gustavo Pichorim Boiko
2007-03-13enable ARB_vertex_buffer_object for more dri driversRoland Scheidegger
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.
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.

2006-10-30Fix bug #8799.Ian Romanick
Properly resize bith the drawable and the readable in mgaUpdateRects. Eliminate the use of the deprecated GetBufferSize interface. Bump driver date.
2006-10-30Refactor mgaXMesaSetFrontClipRects and mgaXMesaSetBackClipRects.Ian Romanick
Combine mgaXMesaSetFrontClipRects and mgaXMesaSetBackClipRects into a single new function called mga_set_cliprects. This enables a small refactor in mgaDDDrawBuffer.
2006-10-30Get DRI drawable from framebuffer object.Ian Romanick
In the software rasterization fallbacks, get the __DRIdrawablePrivate pointer from the driRenderbuffer that is passed in. This eliminates the need for the mesa_drawable pointer in MGA context structure. This partially fixes bug #8799. wincopy no longer produces a black window for the destination window, but it does produce incorrect results if the destination window is resized.
2006-10-18Want to stop passing x/y/width/height to Clear() function.Brian Paul
The coordinates need to be computed after we've got the hw lock. Code updated to: 1. Ignore all/x/y/width/height/ params passed to Clear func. 2. Pass 0,0,0,0,0 to _swrast_Clear() until they're totally removed.
2006-10-15Remove a bunch of "ctx->Driver.function = _swrast_Function" lines sinceBrian Paul
default/fallback functions are already plugged in by the call to _mesa_init_driver_functions().
2006-10-15Remove Driver.ResizeBuffers = _mesa_resize_framebuffer lines.Brian Paul
This is already done by the preceeding call to _mesa_init_driver_functions() which plugs in default functions like that.
