[RFC PATCH 01/19] cpus: Add argument to qemu_get_cpu() to filter CPUs by QOM type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Heterogeneous machines have different type of CPU.
qemu_get_cpu() returning unfiltered CPUs doesn't make
sense anymore. Add a 'type' argument to filter CPU by
QOM type.

Type in "hw/core/cpu.h" and implementation in cpu-common.c
modified manually, then convert all call sites by passing
a NULL argument using the following coccinelle script:

  @@
  expression index;
  @@
  -   qemu_get_cpu(index)
  +   qemu_get_cpu(index, NULL)

RFC: Is this hot path code? What is the cost of this QOM cast check?
