* egl: add EGL_KHR_reusable_sync to egl_driDongwon Kim2016-04-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables an EGL extension, EGL_KHR_reusable_sync. This new extension basically provides a way for multiple APIs or threads to be excuted synchronously via a "reusable sync" primitive shared by those threads/API calls. This was implemented based on the specification at https://www.khronos.org/registry/egl/extensions/KHR/EGL_KHR_reusable_sync.txt v2 - use thread functions defined in C11/threads.h instead of using direct pthread calls - make the timeout set with reference to CLOCK_MONOTONIC - cleaned up the way expiration time is calculated - (bug fix) in dri2_client_wait_sync, case EGL_SYNC_CL_EVENT_KHR has been added. - (bug fix) in dri2_destroy_sync, return from cond_broadcast call is now stored in 'err' intead of 'ret' to prevent 'ret' from being reset to 'EGL_FALSE' even in successful case - corrected minor syntax problems v3 - dri2_egl_unref_sync now became 'void' type. No more error check is needed for this function call as a result. - (bug fix) resolved issue with duplicated unlocking of display in eglClientWaitSync when type of sync is "EGL_KHR_REUSABLE_SYNC" Signed-off-by: Dongwon Kim <[email protected]> Signed-off-by: Marek Olšák <[email protected]>
* egl: move Null check to eglGetSyncAttribKHR to prevent SegfaultDongwon Kim2016-02-191-3/+0
| | | | | | | | | | | | | | Null-check on "*value" is currently done in _eglGetSyncAttrib, which is after eglGetSyncAttribKHR dereferences it. Move the check a layer up (in the beginning of eglGetSyncAttribKHR) to avoid segfaults.

| | | | | | | | | v2: - don't modify "value" in eglGetSyncAttribKHR after an error - rename _egl_api::GetSyncAttribKHR -> GetSyncAttrib - rename GetSyncAttribKHR_t -> GetSyncAttrib_t - rename _eglGetSyncAttribKHR to _eglGetSyncAttrib Reviewed-by: Chad Versace <[email protected]>

* egl: remove #ifdef's for official extensionsChia-I Wu2011-12-201-6/+0
| | | | | | | There is no point in having them when we distribute eglext.h. As for unofficial extensions, there is a chance that we might remove some of them evetually. Keeping the #ifdef's for now should make that easier.
