[Qemu-devel] [PATCH qom-cpu 00/59] QOM CPUState, part 10: CPU loops

["Andreas Färber" <afaerber@suse.de>]

Hello,

Based on my guest-memory-dump cleanup patches, this large series changes
cpu_single_env, first_cpu, next_cpu and thread_env to CPUState.

As a prerequisite, most open-coded CPU loops are replaced by either
qemu_for_each_cpu() or qemu_get_cpu(). Individual review appreciated!

qemu_init_vcpu() is converted to CPUState and moved away from targets.

cpu_unassigned_access(), cpu_dump_state() and cpu_dump_statistics() are turned
into CPUClass methods. exec/hwaddr.h is modified to allows its use in qom/cpu.h.

Available for testing at:
git://github.com/afaerber/qemu-cpu.git qom-cpu-10.v1
https://github.com/afaerber/qemu-cpu/commits/qom-cpu-10.v1

Regards,
Andreas
