| | | | | | | This reverts commit 17090cf3efb0db8fa01b502a9c0df27cbd1a67da. We're reverting this because it causes ABI breakage with the X server. Maybe re-attempt with another patch.
* glapi: Fix a possible race in getting current context/dispatch.Chia-I Wu2009-08-241-1/+4
| | | | | | | | | | | | | | | | | | 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.

| | | | | | Move _glapi_proc typedef from glapitable.h to glapi.h Also, don't include glapitable.h from glapi.h Before we were including the huge glapitable.h file in every .c file.

* Remove _glapi_check_multithread from the interface exported by the loader toIan Romanick2005-08-101-4/+0
| | | | | | | | | | | | | | | | | the driver. The loader now takes care of this for the driver. Remove _glapi_DispatchTSD and give _glapi_Dispatch its semantic (i.e., having a NULL value means that the application is multithreaded and _glapi_get_dispatch must be called). Gut all of the dispatch override code. This removes _glapi_RealDispatch, _glapi_tls_RealDispatch, _glapi_begin_dispatch_override, _glapi_end_dispatch_override, and _glapi_get_override_dispatch. Remove _glapi_get_proc_address, _glapi_get_proc_name, _glapi_get_version, and _glapi_check_table from the loader / driver interface. Reviewed by: Brian Paul
* Major rip-up of internal function insertion interface. The oldmesa_6_3_1Ian Romanick2005-07-281-7/+4
| | | | | | | | | | | | | | | | | | | | | | _glapi_add_entrypoint has been replaced by a new routine called _glapi_add_dispatch.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)
