[Xen-devel] [PATCH 1/4] xen interface for HVM S3

["Ke, Liping" <liping.ke@xxxxxxxxx>]

[PATCH 1/4] xen interface for HVM S3
  - add two sub hypercalls under XEN_DOMCTL_sendtrigger hypercall:
    XEN_DOMCTL_SENDTRIGGER_S3SUSPEND/XEN_DOMCTL_SENDTRIGGER_S3SUSPEND
  - XEN_DOMCTL_SENDTRIGGER_S3SUSPEND will reset all HVM vcpus, pic, apic,
    RTC and HPET. Set BSP eip to 0xfff0, cs base to 0xf0000, and
    also set other registers/msr to the correct value/attributes in real
    mode environment, so HVM will start from rombios post entry directly;
    Then it pause the domain.
  - XEN_DOMCTL_SENDTRIGGER_S3RESUME will unpause the domain
  - add is_s3_suspend flag in domain for logging s3 suspend state
