| From ad6f485d9eb809b67398ce0948844dd30ea1c8e3 Mon Sep 17 00:00:00 2001 |
| From: Tomeu Vizoso <tomeu.vizoso@collabora.com> |
| Date: Tue, 1 Oct 2013 13:19:20 +0200 |
| Subject: [PATCH 02/18] wayland: Add support for the Wayland winsys |
| |
| * Adds EGL_WL_bind_wayland_display extension |
| * Adds wayland-egl library |
| * Adds wl_dispmanx_buffer protocol extension |
| |
| TODO: Check that platform_get_dimensions() returning swapchain_count == 1 is correct |
| |
| TODO: Remove the requirement of passing a valid DispmanX element handle to |
| the SwapBuffers and CreateSurface RPC calls. This will remove the need to open |
| a DispmanX display from the clients. |
| |
| TODO: wl_dispmanx_server_buffer should probably be defined in a |
| private header that can be included from EGL and vc_* instead of in |
| vc_vchi_dispmanx.h |
| |
