Raw Blame History

From 7432d49ddca97b34e402d0108221d34ec69bcd66 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 02/19] 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

Whilst 64-bit userspace is not officially supported, some of the libraries will work for it. To cross compile, install gcc-aarch64-linux-gnu and g++-aarch64-linux-gnu first. For both native and cross compiles, add the option ```--aarch64``` to the buildme command.
Note that this repository does not contain the source for the edidparser and vcdbg binaries due to licensing restrictions.

+To build support for the Wayland winsys in EGL, execute the buildme script like this:
