[Qemu-devel] [PATCH v2 00/10] aarch64 migration for TCG and KVM

[Alex Bennée]

Hi,

This series has already been sent out once before under the guise of
tidying up the pstate access and getting TCG migration working for ARM
v8 hosts. I've since added the final two patches to support KVM based
migration as well.

For KVM migration you will need some patches for the kernel side which
are currently working their way through kvmarm:

https://patches.linaro.org/patchwork/bundle/address@hidden/armv8-migration/

Changes since v1:
  - addressed review comments
  - merged xpsr state into changes
  - checkpatch fixes
  - cleaner handling of integer flag manipulation
  - addition of final KVM patches


Alex Bennée (10):
  target-arm/cpu.h: document various program state functions
  target-arm/cpu.h: common pstate save/restore
  target-arm: Support save/load for 64 bit CPUs
  target-arm: replace cpsr/xpsr/pstate_read calls
  arm/nwfps: replace cpsr_write with set_condition_codes
  linux-user/main.c: __kernel_cmpxchg set env->CF directly
  target-arm: remove last users of cpsr_write
  target-arm: remove final users of pstate_write
  target-arm/kvm.c: better error reporting
  target-arm/kvm: make reg sync code common between kvm32/64
