* mesa: do not use _glapi_new_nop_table() for DRI buildsBrian Paul2015-05-261-2/+60
| | | | | | | | | | | | | | | | | | | Commit 4bdbb588a9d38 introduced new _glapi_new_nop_table() and _glapi_set_nop_handler() functions in the glapi dispatcher (which live in libGL.so). The calls to those functions from context.c would be undefined (i.e. an ABI break) if the libGL used at runtime was older. For the time being, use the old single generic_nop() function for non-Windows builds to avoid this problem. At some point in the future it should be safe to remove this work-around. See comments for more details. v2: Incorporate feedback from Emil. Use _WIN32 instead of GLX_DIRECT_RENDERING to control behavior, move comments.

| | | | | | | | | | | | | | | | | | | | | Use the new _glapi_new_nop_table() and _glapi_set_nop_handler() to improve how we handle calling no-op GL functions. If there's a current context for the calling thread, generate a GL_INVALID_OPERATION error. This will happen if the app calls an unimplemented extension function or it calls an illegal function between glBegin/glEnd. If there's no current context, print an error to stdout if it's a debug build. The dispatch_sanity.cpp file has some previous checks removed since the _mesa_generic_nop() function no longer exists.

* mesa: use fi_type in vertex attribute codeMarius Predut2015-02-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | For 32-bit builds, floating point operations use x86 FPU registers, not SSE registers. If we're actually storing an integer in a float variable, the value might get modified when written to memory. This patch changes the VBO code to use the fi_type (float/int union) to store/copy vertex attributes. Also, this can improve performance on x86 because moving floats with integer registers instead of FP registers is faster. Neil Roberts review: - include changes on all places that are storing attribute values. - check with and without -O3 compiler flag.

| | | | | | | | | | | | | | | | | | | | It doesn't work on Windows because of STDCALL calling convention -- it's the callee responsibility to pop the arguments, and the number of arguments vary with the prototype --, so the stack pointer ends up getting corrupted.

* mesa: Add support for the GL_KHR_context_flush_control extensionNeil Roberts2014-10-281-2/+7
| | | | | | | | | | | | | | The GL side of this extension just provides an accessor via glGetIntegerv for the value of GL_CONTEXT_RELEASE_BEHAVIOR so it is trivial to implement. There is a constant on the context for the value of the enum which is initialised to GL_CONTEXT_RELEASE_BEHAVIOR_FLUSH. The extension is always enabled because it doesn't need any driver interaction to retrieve the value. If the value of the enum is anything but FLUSH then _mesa_make_current will now refrain from calling _mesa_flush. This should only affect drivers that explicitly change the enum to a non-default value. Reviewed-by: Ian Romanick <[email protected]>

Piglit's all.py script only runs primitive-restart with arguments so this case isn't normally hit during a full piglit run.

* mesa: Delete VAO _MaxElement code and index buffer bounds checking.Kenneth Graunke2014-09-191-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fredrik's implementation of ARB_vertex_attrib_binding introduced new gl_vertex_attrib_array and gl_vertex_buffer_binding structures, and converted Mesa's older gl_client_array to be derived state. Ultimately, we'd like to drop gl_client_array and use those structures directly. One hitch is that gl_client_array::_MaxElement doesn't correspond to either structure (unlike every other field), so we'd have to figure out where to store it. The _MaxElement computation uses values from both structures, so it doesn't really belong in either place. We could put it in the VAO, but we'd have to pass it around everywhere. It turns out that it's only used when ctx->Const.CheckArrayBounds is set, which is only set by the (rarely used) classic swrast driver. It appears that drivers/x11 used to set it as well, which was intended to avoid segmentation faults on out-of-bounds memory access in the X server (probably for indirect GLX clients). However, ajax deleted that code in 2010 (commit 1ccef926be46dce3b6b5c76e812e2fae4e205ce7). The bounds checking apparently doesn't actually work, either. Non-VBO attributes arbitrarily set _MaxElement to 2 * 1000 * 1000 * 1000. vbo_save_draw and vbo_exec_draw remark /* ??? */ when setting it, and the i965 code contains a comment noting that _MaxElement is often bogus. Given that the code is complex, rarely used, and dubiously functional, it doesn't seem worth maintaining going forward. This patch drops it. This will probably mean the classic swrast driver may begin crashing on out of bounds vertex buffer access in some cases, but I believe that is allowed by OpenGL (and probably happened for non-VBO accesses anyway). There do not appear to be any Piglit regressions, either.

| | | | | | | | | | | | | | | | | | | | | | | During the early one_time_init phase of context creation, we initialize two global gl_extensions structures. We read the MESA_EXTENSION_OVERRIDE environment variable, and store positive and negative overrides in two structures: * struct gl_extensions _mesa_extension_override_enables * struct gl_extensions _mesa_extension_override_disables These are filled before the driver initializes extensions and constants, therefore the driver can make adjustments based on the desired overrides. This can be useful during development of a new extension where the extension is only partially ready. The driver can't actually advertise support for the extension, but if it sees that the override is set for the extension, then it can expose more supported parts of the extension, such as upgrading context constants.
