AMD Xilinx features in 4.12

• Refer to 2023.1 Release Notes for Open Source Components

• Initial support for Mesa LIMA drivers.

  • libmali is available but default is set to lima for Yocto Project distributions (without using meta-petalinux layer).

  • To enable libmali, set config variable in local.conf

    Code Block
    DISTRO_FEATURES:append:aarch64 = " libmali"

• New tool called gen-machinceconf which accepts xsa as input and generates yocto bsp machine configuration file. Refer gen-machine-conf repo README for more details.

• Instruction for creating a machine configuration file has been updated, Refer to https://github.com/Xilinx/meta-xilinx/blob/master/meta-xilinx-core/conf/machine/README

• New docs directory for additional documentation, Refer https://github.com/Xilinx/meta-xilinx/docs

• Renamed u-boot-zynq-scr recipe to u-boot-xlnx-scr

• The default wic/wks file is provided in meta-xilinx/meta-xilinx-core/wic/xilinx-default-sd.wks

  • The default file uses ‘rootfs’, instead of ‘bootimg-partition’ for the /boot partition. This allows target package upgrade. ‘bootimg-partition’ is still supported.

  • The default file also uses --label boot. This ensures the constructed fstab will mount the correct partition(s).

• Move AIE recipes from meta-xilinx-tools to meta-xilinx-core layer.
