2009-08-24glapi: Fix a possible race in getting current context/dispatch.Chia-I Wu
There is a possbile race that _glapi_Context is reset by another thread after it is tested in GET_CURRENT_CONTEXT but before it is returned. We definitely do not want a lock here to solve the race. To have correct results even under a race, no other threads should reset _glapi_Context (or _glapi_Dispatch). This patch adds a new global variable _glapi_SingleThreaded. Since _glapi_Context or _glapi_Dispatch are no longer reset, _glapi_SingleThreaded is tested instead, before accessing them. DRI drivers compiled with this patch applied will not work with existing libGL.so because of the missing new symbol. If this turns out to be a real problem, this patch should be reverted.

2009-08-24glapi: Fix a race in accessing context/dispatch TSD.Chia-I Wu
If multiple threads set/get a TSD at roughly same time for the first time, glthread might (wrongly) initialize it more than once. This patch solves the race by initializing context/dispatch TSDs early. Acked-by: Ian Romanick <ian.d.romanick@intel.com> Signed-off-by: Chia-I Wu <olvaffe@gmail.com>
2009-08-24glapi: Protect _glapi_check_multithread by a mutex.Chia-I Wu
Multiple threads might call _glapi_check_multithread at roughly the same time. It is possbile that all of them are wrongly regarded as firstCall if there is no mutex. This bug causes xeglthreads to crash sometimes. Acked-by: Ian Romanick <ian.d.romanick@intel.com> Signed-off-by: Chia-I Wu <olvaffe@gmail.com>

2009-08-03mesa: fix up some GLAPI XMLRobert Ellison
- Added specifications for the extensions GL_APPLE_flush_buffer_range and GL_APPLE_texture_range - EXT_framebuffer_object.xml strangely held specifications for both the GL_EXT_framebuffer_object extension and the GL_EXT_texture_array extension. Split out the GL_EXT_texture_array data into its own file.

2009-02-26mesa: Resurrect SPARC asm code.David S. Miller
This rewrites the sparc GLAPI code so that it's PIC friendly and works with all of the TLS/PTHREADS/64-bit/32-bit combinations properly. As a result we can turn SPARC asm back on. Currently it's only enabled on Linux, as that's the only place where I can test this stuff out. For the moment the cliptest SPARC asm routines are disabled as they are non-working. The problem is that they use register %g7 as a temporary which is where the threading libraries store the thread pointer on SPARC. I will fix that code up in a future change as it's a pretty important routine to optimize. Like x86 we do the runtime patch as a pthread once-invoked initializer in init_glapi_relocs(). Unlike x86, however, our GLAPI stubs on SPARC are just two instruction sequences that branch to a trampoline and put the GLAPI offset into a register. The trampoline is what we run-time patch. The stubs thus all look like: glFoo: ba __glapi_sparc_foo_stub sethi GLAPI_OFFSET(glFOO) * PTR_SIZE, %g3 This actually makes generate_entrypoint() a lot simpler on SPARC. For this case in generate_entrypoint() we generate stubs using a 'call' instead of the 'ba' above to make sure it can reach. In order to get a proper tail call going here, in the unpatched case, we do several tricks. To get the current PC, for example, we save the return address register into a temporary, do a call, save the return address register written by the call to another temporary, then restore the original return address register value. This is to avoid having to allocate a stack frame. This is necessary for PIC address formation. This new GLAPI scheme lets us get rid of the ugly SPARC GLAPI hacks in __glXInitialize() and one_time_init(). Signed-off-by: David S. Miller <davem@davemloft.net>

2008-12-14GLX: Include glapi.h before glapitable.hIan Romanick
A previous commit (2dbc515a669be123a019aeb4aa5aae6b1679f6a9) change some of the interdependencies between these two header files. Now glapi.h must be included before glapitable.h.
2008-12-14Return 0 as the request size when the pixels parameter is NULLNeil Roberts
img_null_flag was being ignored when calculating the size of a request so a BadLength error gets thrown for glTexImage3D when the pixels parameter is NULL. See bug #11003
2008-12-14GLX: Fix protocol for glTexSubImage#DIan Romanick
The TexSubImage commands do not have the "NULL image" flag that was introduced with glTexImage3D. However, there is a CARD32 pad element where that flag would be. Removing the img_null_flag causes the flag to be removed from the protocol. This changes the protocol and breaks everything. In order to prevent needing to hand-code all of the TexSubImage functions, a new attribute was added to the param element. This new attribute, called "padding," is a boolean flag that selects whether or not the parameter is a real parameter (default / false) or is protocol padding (true) that does not appear in the function's parameter list. This change resulted in a number of changes to other Python scripts. In almost all cases parameters with the is_padding flag set should not be emitted. This patch only changes the the XML, the DTD, and the generator scripts. It does NOT include the resulting changes to the generated code. Generated code in the X server is also changed by the script / XML changes in this patch. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>

2008-11-10GLX: fix out-of-bounds memory issue in indirect glAreTexturesResident()Brian Paul
See bug 18445. When getting array results, __glXReadReply() always reads a multiple of four bytes. This can cause writing to invalid memory when 'n' is not a multiple of four. Special-case the glAreTexturesResident() functions now. To fix the bug, we use a temporary buffer that's a multiple of four bytes in length. NOTE: this commit also reverts part of commit 919ec22ecf72aa163e1b97d8c7381002131ed32c (glx/x11: Added some #ifdef GLX_DIRECT_RENDERING protection) which directly edited the indirect.c file rather than the python generator! I'm not repairing that issue at this time.
