I might be missing something here, but can the free-form, anonymous
python code block be avoided? Don't we have PACKAGES_DYNAMIC for this
purpose?
PACKAGES_DYNAMIC is for when we can't predict the packages a recipe
might generate. A good example might be kernel modules.
You're right that we could add a do_split_packages() call to the qemu
recipe have have it generate these dynamically.
The downside would be the namespacing as dynamic packages need to have
specific namespaces (e.g. kernel-module-XXX). This means qemu-mips
wouldn't be an option (conflicts with non dynamic packages like qemu-
dbg).
We could use a more specific prefix like qemu-system-XXX and qemu-user-
XXX and use do_split_packages
I did also wonder about using more specific inline python for some of
this, things along the lines of:
PACKAGES += '${@" ".join("qemu-system-" + x for x in
d.getVar('QEMU_TARGETS').split())}'
I'm also not a fan of the python code block.
We do use do_split_packages() in other recipes like gstreamer to handle
things like this.
And in case anyone hasn't looked it up, this is the meta-virt solution:
https://git.yoctoproject.org/meta-virtualization/tree/recipes-devtools/qemu/qemu-package-split.inc
Thanks! I did see this before I send out
https://patchwork.yoctoproject.org/project/oe-core/patch/[email protected].
Considering to dynamically generate the sub-packages via QEMU_TARGETS,
so I use a python block and don't need the change the code even
QEMU_TARGETS has some change.
But I should let all sub-package to depend the qemu-7.2.0*.rpm.
Thanks,
Which I'll have to re-work once (if) something lands in core.
It isn't suitable as-is, but it doesn't need any python code to suit
the on-target system emulation needs of meta-virt.

Cheers,
Richard
