[PATCH 2/4]: QEMU interface for HVM virtual S3
- add S3 suspend logic in PM1A control register. when guest write
specific value to this register,
QEMU will trigger S3 sleep by
* reset all qemu device
* set CMOS shutdown status as S3 resume, so that rombios will do
S3 resume later
* call HVMOP_s3_suspend hypercall to put HVM domain into S3 sleep
state.
