There's no commercial advantage to emulated machines. I've been using qemu since
it was bochs, and have booted and tried pretty much everything over
the years .. I
just like emulated platforms and machines.

The work that I did was hacks, that I had no interest in fully
supporting in Yocto. Everytime
we add a machine, there's a tax for every uprev cycle, and every
build. If you add it, you
can't let it bit rot.

I don't think I need to be accused of intentionally doing or not doing anything.

You do realize that the entire reason that layer isn't updated, is that we
agreed with Xilinx and the other active contributors to merge all the
support into their layer, and kill off the old one. It simply took us a while to
get everyone up to speed and aligned.

Clearly you aren't on the linux-yocto mailing list :)

Wind River works upstream first, we don't have any commercial support for any of
the emulations you are talking about. Simple because I say I've uses something,
doesn't mean that it is a commercial product.

I'd suggest toning down the conversation and accusations .. they
aren't productive
I'm just trying to help.

I'm not following what you mean here  .. sorry.
