* Remove Xcalloc/Xmalloc/Xfree callsMatt Turner2012-09-051-22/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These calls allowed Xlib to use a custom memory allocator, but Xlib has used the standard C library functions since at least its initial import into git in 2003. It seems unlikely that it will grow a custom memory allocator. The functions now just add extra overhead. Replacing them will make future Coccinelle patches simpler.

* dri: Emit a critical error if a named driver fails to load.Carl Worth2012-02-081-0/+2
| | | | | | | | | Something has gone wrong if we were asked to load a driver of a specific name, but it failed to load for some reason. The user really should be made aware of this, (and instructed to set LIBGL_DEBUG for more details). Reviewed-by: Eugeni Dodonov <[email protected]>

* glx: Send DestroyContext protocol at the correct timesIan Romanick2011-12-191-3/+0
| | | | | | | | | | | | | | | | | | | | | | | Send the DestroyContext protocol immediately when glXDestroyContext is called, and never call it when glXFreeContextEXT is called. In both cases, either destroy the client-side structures or, if the context is current, set xid to None so that the client-side structures will be destroyed later. I believe this restores the behavior of the original SGI code. See src/glx/x11 around commit 5df82c8. The spec doesn't say anything about glXDestroyContext not really destroying imported contexts (it acts like glXFreeContextEXT instead), but that's what the original code did. Note that glXFreeContextEXT on a non-imported context does not destroy it either. Fixes the piglit test glx-free-context. NOTE: This is a candidate for the 7.11 branch.

* glx: Don't create a shared context if the other context isn't the same kindIan Romanick2011-12-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each of the DRI, DRI2, and DRISW backends contain code like the following in their create-context routine: if (shareList) { pcp_shared = (struct dri2_context *) shareList; shared = pcp_shared->driContext; } This assumes that the glx_context *shareList is actually the correct derived type. However, if shareList was created as an indirect-rendering context, it will not be the expected type. As a result, shared will contain garbage. This garbage will be passed to the driver, and the driver will probably segfault. This can be observed with the following GLX code: ctx0 = glXCreateContext(dpy, visinfo, NULL, False); ctx1 = glXCreateContext(dpy, visinfo, ctx0, True); Create-context is the only case where this occurs. All other cases where a context is passed to the backend, it is the 'this' pointer (i.e., we got to the backend by call something from ctx->vtable). To work around this, check that the shareList->vtable->destroy method is the same as the destroy method of the expected type. We could also check that shareList->vtable matches the vtable or by adding a "tag" to glx_context to identify the derived type. NOTE: This is a candidate for the 7.11 branch.

* glx: Fix indirect fallback when a non-Mesa GLX extension is present.Aaron Plattner2011-12-071-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When driCreateScreen calls driConvertConfigs to try to convert the configs for swrast, it fails and returns NULL. Instead of checking, it just clobbers psc->base.configs. Then, when the application asks for the FBconfigs, there aren't any. Instead, make the caller responsible for freeing the old modes lists if both calls to driConvertConfigs succeed. Without the second fix, glxinfo fails unless you run it with LIBGL_ALWAYS_INDIRECT: $ glxinfo name of display: :0.0 Error: couldn't find RGB GLX visual or fbconfig $ LIBGL_ALWAYS_INDIRECT=1 glxinfo name of display: :0.0 display: :0 screen: 0 direct rendering: No (LIBGL_ALWAYS_INDIRECT set) server glx vendor string: NVIDIA Corporation server glx version string: 1.4 [...] Signed-off-by: Aaron Plattner <[email protected]> Reviewed-and-tested-by: Ian Romanick <[email protected]> Signed-off-by: Brian Paul <[email protected]>

* glx: implement drawable refcounting.Stéphane Marchesin2011-06-171-2/+4
| | | | | | | | | | | | The current dri context unbind logic will leak drawables until the process dies (they will then get released by the GEM code). There are two ways to fix this: either always call driReleaseDrawables every time we unbind a context (but that costs us round trips to the X server at getbuffers() time) or implement proper drawable refcounting. This patch implements the latter. Signed-off-by: Antoine Labour <[email protected]> Signed-off-by: Stéphane Marchesin <[email protected]> Reviewed-by: Adam Jackson <[email protected]>

* glx: Move initialization of ext_list_first_time to where it's storage is ↵Brian Paul2010-03-051-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | allocated Move the initialization of ext_list_first_time from all of the DRI loader's CreateScreen routines, to where the storage for the screen config is allocated. It needs to get set in the screen-config even if DRI is forced off using LIBGL_ALWAYS_INDIRECT, so that psc->direct_support is initialized correctly, otherwise __glXExtensionBitIsEnabled() always returns FALSE Specifically, this causes a problem with an X server which advertises GLX<=1.2, and the GLX_SGIX_fbconfig extension. glXGetFBConfigFromVisualSGIX() uses __glXExtensionBitIsEnabled() to check if the GLX_SGIX_fbconfig extension is available, but that function won't return correct information because that data has never been initialized, because ext_list_first_time was never set...
