[PATCH 00/19] cpus: Step toward removing global 'first_cpu' |
|

Heterogeneous machines have different type of CPU.
In that context, both 'first_cpu' and qemu_get_cpu(index)
don't make much sense.
This series first add a 'filter CPU type' argument to
qemu_get_cpu(), so the behavior respects what we currently
expect, then replace 'first_cpu' by a qemu_get_cpu(0) call.
Testing pass, but I'm still unsure about performance impact.
With this series applied, what is left is:
[OK]
- hw/core/generic-loader.c:127: s->cpu = qemu_get_cpu(s->cpu_num,
NULL);
- linux-user/syscall.c:8990: if (CPU_NEXT(first_cpu)) {
- monitor/hmp-cmds-target.c:106: cs = vcpu >= 0 ? qemu_get_cpu(vcpu,
NULL) : mon_get_cpu(mon);
- stats/stats-hmp-cmds.c:150: CPUState *cpu = qemu_get_cpu(cpu_index,
NULL);
- system/cpus.c:754: cpu = qemu_get_cpu(cpu_index, NULL);
[likely OK, we don't support heterogeneous accelerators]
- accel/kvm/kvm-all.c:3581: kvm_arch_on_sigbus_vcpu(first_cpu, code, addr);
- accel/kvm/kvm-all.c:4255: if (first_cpu) {
- accel/kvm/kvm-all.c:4258: query_stats_schema_vcpu(first_cpu,
&stats_args);
[need some toughts...]
