Hi, So, in London we discussed moving the drm compositor to a new gbm_surface interface, which would allow the buffer management to be handled by the egl implementation by calling eglSwapBuffers. Here's a prototype implementation of such an interface in mesa and a patch to wayland-demos moving compositor-drm to it. With the changes, the compositor creates a gbm_surface for each output and from that it creates egl surfaces. The compositor is still responsible for the actual flipping. In order to do that, the new interface includes a function for getting a bo for a gbm_surface's front buffer. This change does not impact the ability of scanning out a client buffer. Thanks, Ander Ander Conselvan de Oliveira (9): gbm: add gbm_surface interface egl_dri2: make flush extension useable by drm platform gbm: implement basic gbm_surface on dri backend egl_dri2: use gbm_surface as the native window type in drm platform gbm: creates hooks for dri2_loader_extension in dri backend egl_dri2: implement get_buffers and swap_buffers in drm platform gbm: implement gbm_surface_get_bo in dri backend gbm: add a release_buffer callback to dri backend egl_dri2: add triple buffering support to drm platform src/egl/drivers/dri2/egl_dri2.h | 18 ++ src/egl/drivers/dri2/platform_drm.c | 340 ++++++++++++++++++++++++++++++++++- src/gbm/backends/dri/gbm_dri.c | 147 +++++++++++++++- src/gbm/backends/dri/gbm_driint.h | 31 +++- src/gbm/main/gbm.c | 26 +++ src/gbm/main/gbm.h | 15 ++ src/gbm/main/gbmint.h | 14 ++ 7 files changed, 588 insertions(+), 3 deletions(-) -- 1.7.4.1 _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/wayland-devel
