[PATCH v2 0/5] vCPU hotunplug related memory leaks

Posted by Mark Kanda 2 years, 1 month ago

This series addresses a few vCPU hotunplug related leaks (found with Valgrind).

v2: Create AccelOpsClass::destroy_vcpu_thread() for vcpu thread related cleanup
(Philippe)

Mark Kanda (5):
  accel: Introduce AccelOpsClass::destroy_vcpu_thread()
  softmmu/cpus: Free cpu->thread in destroy_vcpu_thread_generic()
  softmmu/cpus: Free cpu->halt_cond in destroy_vcpu_thread_generic()
  cpu: Free cpu->cpu_ases in cpu_exec_unrealizefn()
  i386/cpu: Free env->xsave_buf in x86_cpu_unrealizefn()
