[meta-xilinx] Xilinx QEMU in meta-xilinx

[Alistair Francis]

Hello everyone,

Xilinx maintains it's own version of QEMU based on the mainline
version of QEMU: https://github.com/xilinx/qemu/

This tree has a lot of focus on extra support and features for the
Xilinx architectures. Although we are trying to get all of these
features upstream to mainline QEMU it is slow work and unfortunately
not always possible.

We are looking at providing support to build the Xilinx QEMU in the
meta-xilinx layer. This could be disabled by default and enabled by
changing the PREFERRED_VERSION_qemu variable. The advantage this would
bring is much more accurate and extensive support for emulating the
Xilinx platforms.

What is the consensus on this, do people think that including the
Xilinx tree of QEMU is acceptable?

Thanks,

Alistair
