[Mesa-dev] [PATCH 1/2] egl_dri2: Add support for Tizen
Mun Gwan-gyeong
elongbug at gmail.com
Wed Apr 12 00:48:08 UTC 2017
From: "Mun, Gwan-gyeong" <kk.moon at samsung.com>
Add platform_tizen.c that supports _EGL_PLATFORM_TIZEN. It works with libtpl-egl
(Tizen Porting Layer for egl), libtbm(Tizen Buffer Manager) where back buffers
of windows are backed by GEM objects.
In Tizen a native window has a queue (tbm_surface_queue) of back buffers
allocated by the WL_TBM(wayland client case, WL_TBM is abbreviation of
wayland-tbm protocol) or gbm ( tizen has implements gbm with tbm) or tbm
through tbm_backend.
For each frame, EGL needs to
dequeue the next back buffer
render to the buffer
enqueue the buffer
After enqueuing, the buffer is no longer valid to EGL.
It supports DRI image loader extension, DRI dri2 loader extension and DRI swrast
loader extension.
It supports EGL_NATIVE_SURFACE_TIZEN target type for eglCreateImageKHR.
(https://www.khronos.org/registry/EGL/extensions/TIZEN/EGL_TIZEN_image_native_surface.txt)
BindWaylandDisplayWL / UnbindWaylandDisplayWL / QueryWaylandBufferWL are
overloaded because tizen platform has its own instead of WL_DRM.
