Selecting particular backends

Wayland/GBM backend:

2019.1:

From 2019.1 release, selecting Mali backend is decoupled from 'DISTRO_FEATURES', another variable is introduced 'MALI_BACKEND_DEFAULT' to create proper link. By default, plnx build system will try to package all the backends in the rootfs and depending upon the value of 'MALI_BACKEND_DEFAULT' we create a link to the correct backend. Fbdev, X11, wayland and headless are the choices we have, assigning incorrect name would yield a link to headless.

For example: Once you have selected libmali through 'petalinux-config -c rootfs', add following parameters to <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf to select wayland. 

Users can still modify DISTRO_FEATURES, in order to reduce the size of rootfs, but remember selecting Mali backend wont be impacted.

2018.3:

From 2018.3 release, Mali will support wayland/GBM backend in addition to fbdev and X11.

For example: Once you have selected libmali through 'petalinux-config -c rootfs' unselect 'packagegroup-petalinux-matchbox' and 'packagegroup-petalinux-x11' and add following parameters to <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf 

This packagegroup ensures all the essential wayland/weston packages are packaged into the rootfs for having a wayland/weston application work out of the box. On boot, export following parameter in your terminal console.

Now, you can run sample benchmarking application glmark2-es2-wayland and glmark2-es2-drm.

X11 backend:

By default, Mali supports X11 backend. Just select libmali-xlnx package from 'petalinux-config -c rootfs'. The root filesystem should now have libmali with X11 support. Also, please select at least one window manager.

For example: packagegroup-petalinux-matchbox.

Fbdev backend:

2019.1:

From 2019.1 release,to select fbdev, Just select libmali-xlnx package from 'petalinux-config -c rootfs' and add the following lines to <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf

2018.3:

Up to 2018.3, in order to have Mali fbdev backend, please add following lines to <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf

Headless-EGL backend:

2019.1:

From 2019.1 onwards, please add following lines to <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf.

2018.3:

This backend is available from 2018.3 release, please add following lines to <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf. 

QT wayland/KMS/GBM plugin:

In addition to enable Wayland Mali backend support above, select 'packagegroup-petalinux-qt' in 'petalinux-config -c rootfs' and perform a petalinux-build.

Wayland plugin:

Once weston shows up, export the following environment variables for wayland plugins. 

Now you can run any example applications like  /usr/share/qt5/examples/opengl/textures/textures

KMS/GBM plugin:

For this plugin ensure that weston is not running and export the following environment variables

Now you can run any example applications like /usr/share/qt5/examples/opengl/textures/textures.
