[PATCH 0/2] cpu: Avoid latent bug calling cpu_reset() on uninitialized vCPU

Posted by Philippe Mathieu-Daudé 5 years, 8 months ago

Two trivial patches to avoid each (new) architecture to track
a bug already resolved once on ARM: cpu_reset() modify fields
in the CpuState while the state is not yet allocated.

Philippe Mathieu-Daudé (2):
  cpu: Do not reset a vCPU before it is created
  cpu: Assert a vCPU is created before resetting it
