3. Using glmark2

Building glmark2 generates 2 binaries:

• glmark2-es2-wayland, to launch glmark2 benchmark as a wayland client.
• glmark2-es2-drm, to launch glmark2 benchmark as a native DRM/GBM openGLES application.

3.1. glmark2-es2-wayland

• Start Weston (if not already started)

 systemctl start weston@root.service

• Launch glmark2

 glmark2-es2-wayland

3.2. glmark2-es2-drm

• Stop Weston

 systemctl stop weston@root.service

• The DRM display mode may need to be set and the DRM master token released so that glmark2 can use the DRM interfaces. This depends on the glmark2 version. For instance:

 modetest -s 27:720x1280 -d &

Note: The connector and the mode are given as an example.
