All,
OpenAMP support is coming to End Of Life on AMD-Xilinx zynq7000 platform. Few reasons to remove this support:
1) Zynq7000 is very old platform. There are newer advanced platforms that have replaced zynq7000 for most use cases. 2) Zynq7000 does not have Linux remoteproc support in upstream kernel. New platforms (Zynq Ultrascale Plus and later), have stable remoteproc support in. upstream kernel. No plans to upstream remoteproc drivers for zynq7000. 3) AMP use cases on zynq7000 is very limited and not lot of customers are using it as AMP system. 4) zynq7000 code base is not maintained very well. Removing support makes sense in such case, instead of carrying broken / untested code.
Last known stable working OpenAMP demos on zynq7000 platform is available with petalinux-2023.2 release.
From 2024.2 all zynq7000 AMP use case related code base will be removed.
Here is WIP PR in open-amp library: https://github.com/OpenAMP/open-amp/pull/604
