[PATCH v3 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).

v3:
- patch 4: create cpu_address_space_destroy() to free cpu_ases (Phillipe)
- patch 5: create <kvm, hvf>_destroy_vcpu_thread() to free xsave_buf (Phillipe)

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 generic_destroy_vcpu_thread()
  softmmu/cpus: Free cpu->halt_cond in generic_destroy_vcpu_thread()
  cpu: Free cpu->cpu_ases in cpu_address_space_destroy()
  i386/cpu: Free env->xsave_buf in KVM and HVF destory_vcpu_thread
    routines
