[Qemu-devel] [PATCH V3] tests/acpi: speedup acpi tests

[Marcel Apfelbaum]

Use kvm acceleration if available.
Disable kernel-irqchip and use qemu64 cpu
for both kvm and tcg cases.

Using kvm acceleration saves about a second
and disabling kernel-irqchip has no visible
performance impact.

---
v2->v3:
  - Get rid of -cpu qemu64, is the default anyway (Paolo)
  - Removed a not needed chunk

v1->v2:
  - Disable kernel_irqchip an use qemu64 cpu (Michael)
  - Replace check_kvm function with -machine accel=kvm:tcg (Paolo)
  - Don't pass the machine parameter to test_acpi_one
