2009-08-25Revert "glapi: Fix a possible race in getting current context/dispatch."Brian Paul
This reverts commit 17090cf3efb0db8fa01b502a9c0df27cbd1a67da. We're reverting this because it causes ABI breakage with the X server. Maybe re-attempt with another patch.
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>
2009-02-26mesa: 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>

2007-02-20Delete two invalid assertions.Ian Romanick

2006-10-13Fix dumb build errors.Ian Romanick
I always build with -DGLX_USE_TLS, so I never hit these paths. glapi.h is required in some places because _glapi_Dispatch is declared there, but _glapi_tls_Dispatch is declared in glthread.h.

2006-10-11Fix bug #4681.Ian Romanick
glDeleteTextures and glDeleteTexturesEXT were erroneously listed as aliases of each other. For anything /except/ GLX protocol they are aliases. This set of changes allows functions that are functionally identical but have different GLX protocol to be listed as aliases. When building with GLX_INDIRECT_RENDERING set, different static functions are used. These functions determine whether the current context is direct rendering or not. If the context is direct rendering, the aliased function (e.g., glDeleteTextures in the case of glDeleteTexturesEXT) is called. If the context is not direct rendering, the correct GLX protocol is sent. For a deeper explanation of what is changed, please see: http://dri.freedesktop.org/wiki/PartiallyAliasedFunctions
2006-08-29remove assertion that referenced &glSetFenceNV for debug testBrian Paul
2006-08-22The TLS dispatch functions for x86-64 are fixed-size, just like onIan Romanick
x86. This means that the position of each dispatch function can be calculated as (dispatch_offset * size_of_function) + glNewList. This allows us to not store the function pointers in glprocs_table_t. This same optimization has been done for quite some time on x86. We could probably also do this for some cases of the SPARC dispatch as well.
2006-08-22Add new attribute called static_dispatch to the <function> element. ThisIan Romanick
boolean attribute, which defaults to true, determines whether or not a static dispatch function is available in libGL for applications to link against. Ideally, any new functions that are not part of the ABI should not have directly accessable dispatch functions. This forces applications to use glXGetProcAddress to access these functions. By doing this we can gracefully remove functions from libGL without breaking the linkage of applications. Note that the static dispatch functions are still generated. However, they are given names like gl_dispatch_stub_820 and are marked with the "hidden" linker attribute. All extension functions added since the previous Mesa release (6.5) have been marked as 'static_dispatch="false"'.

2005-07-28Major rip-up of internal function insertion interface. The oldIan Romanick
_glapi_add_entrypoint has been replaced by a new routine called _glapi_add_dispatch. This new routine dynamically assignes dispatch offsets to functions added. This allows IHVs to add support for extension functions that do not have assigned dispatch offsets. It also means that a driver has no idea what offset will be assigned to a function. The vast majority of the changes in this commit account for that. An additional table, driDispatchRemapTable, is added. Functions not in the Linux OpenGL ABI (i.e., anything not in GL 1.2 + ARB_multitexture) has a fixed offset in this new table. The entry in this table specifies the offset in of the function in the real dispatch table. The internal interface was also bumped from version 20050725 to 20050727. This has been tested with various programs in progs/demos on: radeon (Radeon Mobility M6) r128 (Rage 128 Pro) mga (G400)

- The test for whether or not we're building for 64-bit is '#ifdef __arch64__'. This appears to be correct on both Linux and Solaris. - The test for Solaris is now '#if defined(SVR4) || defined(__SVR4) || defined(__svr4__)'. GCC 3.4.0 has all three defined on Solaris 9. - Enables assembly language clip routines. - Fixes to make GLSL code build on Solaris. - Update gl_SPARC_asm.py.
