2012-06-19Add PIIX4 properties to control PM system states.Gleb Natapov1-1/+1
This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.

2012-02-24suspend: switch acpi s3 to new infrastructure.Gerd Hoffmann1-2/+2
This patch switches pc s3 suspend over to the new infrastructure. The cmos_s3 qemu_irq is killed, the new notifier is used instead. The xen hack goes away with that too, the hypercall can simply be done in a notifier function now. This patch also makes the guest actually stay suspended instead of leaving suspend instantly, so it is useful for more than just testing whenever the suspend/resume cycle actually works.

2012-02-24acpi: add acpi_pm1_evt_write_enGerd Hoffmann1-0/+1
Do APCIREGS->pm1.evt.en updates using the new acpi_pm1_evt_write_en function, so the acpi code will see those updates. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-24acpi: don't pass overflow_time to acpi_pm1_evt_get_stsGerd Hoffmann1-1/+1
Pretty pointless, can easily be reached via ACPIREGS now. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-02-24acpi: add ACPIREGSGerd Hoffmann1-19/+29
All those acpi structs are not independent from each other. Various acpi functions expecting multiple acpi structs passed in are a clean indicator for that ;) So this patch bundles all acpi structs in the new ACPIREGS struct, then use it everythere pass around acpi state.
