* glx: use v2 of DRI_ConfigOptionsNicolai Hähnle2017-08-021-14/+99
| | | | | | | | | Most of the change is concerned with avoiding memory leaks, since v2 of the DRI extension returns a malloc'ed string. This also allows us to resolve the long-standing issue of keeping drivers loaded when returning from glXGetDriverConfig. Reviewed-by: Marek Olšák <[email protected]>

* glx: Implement the libglvnd interface.Kyle Brenneman2016-05-301-2/+2
| | | | | | | | | | | | | | | | With reference to the libglvnd branch: https://cgit.freedesktop.org/mesa/mesa/log/?h=libglvnd This is a squashed commit containing all of Kyle's commits, all but two of Emil's commits (to follow), and a small fixup from myself to mark the rest of the glX* functions as _GLX_PUBLIC so they are not exported when building for libglvnd. I (ajax) squashed them together both for ease of review, and because most of the changes are un-useful intermediate states representing the evolution of glvnd's internal API.

* glx: Add an error message when a direct renderer's createScreen() routine failsJon TURNEY2014-06-181-1/+3
| | | | | | | | | | | | | | | because no matching fbConfigs or visuals could be found. Nearly all the error cases in *createScreen() issue an error message to diagnose the failure to initialize before branching to handle_error. The few remaining error cases which don't should probably do the same. (At the moment, it seems this can be triggered in drisw with an X server which reports definite values for MAX_PBUFFFER_(WIDTH|HEIGHT|SIZE), because those attributes are checked for an exact match against 0.)

* glx: Add an optional function call for getting the DRI driver interface.Eric Anholt2013-10-241-1/+1
| | | | | | | | | | | | | | The previous interface relied on a static struct, which meant that the driver didn't get a chance to edit the struct before the struct got used. For megadrivers, I want struct specific to the driver being loaded. v2: Fix the prototype in the docs (caught by Marek). Since the driver name was in the function, we didn't need to also pass it in. v3: Fix asprintf error checking (caught by Matt's gcc).

* dri: Allow config options to be passed to the loader through extensions.Eric Anholt2013-10-241-3/+14
| | | | | | | | | | | | | | | Turns out already we have this nice mechanism for providing optional things from the driver to the loader, and I was going to have to rename the public global symbol to avoid conflicts when doing megadrivers. While the former __driConfigOptions is technically loader interface, this is the only loader that made use of that symbol. Continue paying attention to it if we can't find the new option, to retain compatibility with old drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.
