[Qemu-devel] [PATCH qom-cpu 0/6] cpu: Unifying features parsing

[Andreas Färber]

Hello,

Prompted by Alexey's desire for tweakable PowerPCCPU properties but also by
Peter's wish for ARMCPU properties, this series sets out to align cpu_model
parsing across targets.

QemuOpts would've been nice to use, but on the one hand x86 and sparc use
QemuOpts-incompatible +foo and -foo syntax (which accumulate rather than apply
immediately) and on the other linux-user and bsd-user don't use QemuOpts at all.

The x86 implementation is closest to the proposed API, save for some laziness.
SPARC is brought in line. And as fallback for the remaining targets a new
implementation, derived from x86 but supporting only key=value format, is added.

To facilitate using this infrastructure, a generic CPU init function is created.

Only lightly tested. Available at:
git://github.com/afaerber/qemu-cpu.git qom-cpu-features.v1
https://github.com/afaerber/qemu-cpu/commits/qom-cpu-features.v1

Regards,
Andreas
