2015-03-01acpi: make build_*() routines static to aml-build.cIgor Mammedov
build_*() routines were used for composing AML structures manually in acpi-build.c but after conversion to AML API they are not used outside of aml-build.c anymore, so hide them from external users.

2015-02-26pc: acpi-build: create CPU hotplug IO region dynamicallyIgor Mammedov
it replaces a static complied in DSDT MMIO region for CPU hotplug with one created at runtime leaving only truly static CPU hotplug related ASL bits in DSDT. It also puts CPU_HOTPLUG_RESOURCE_DEVICE into PCI0 scope and reserves resources from it, preparing for dropping manual hole punching in PCI0._CRS. Later it also would make easier to reuse current ACPI CPU hotplug on other targets. Also later it would be possible to move remaining CPU hotplug ASL methods into build_ssdt() and add all CPU hotplug related AML into SSDT only when CPU hotplug is enabled, further reducing ACPI tables blob if CPU hotplug isn't used. impl. detail: Windows XP can't handle /BSODs/ OperationRegion declaration in DSDT when variable from SSDT is used for specifying its address/length and also when Field declared in DSDT with OperationRegion from SSDT if DSDT is being parsed before SSDT. But it works just fine when referencing named fields from another table. Hence OperationRegion and Field declaration are moved to SSDT to make XP based editions work. PS: Later Windows editions seem to be fine with above conditions. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.

2015-02-26acpi: include PkgLength size only when requestedIgor Mammedov
Named/Reserved{Field} definition uses PkgLength [1] encoding to specify field length, however it doesn't include size of PkgLength field itself, while other block objects that have explicit length of its body account for PkgLength size while encoding it [2]. This special casing isn't mentioned in ACPI spec, but that's what 'iasl' compiles NamedField to so add extra argument to build_prepend_pkg_length() to allow it handle the case. -- 1.

2015-01-26ich9: add disable_s3, disable_s4, s4_val propertiesAmit Shah
PIIX4 has disable_s3 and disable_s4 properties to enable or disable PM functions. Add such properties to the ICH9 chipset as well for the Q35 machine type. S3 / S4 are not guaranteed to always work (needs work in the guest as well as QEMU for things to work properly), and disabling advertising of these features ensures guests don't go into zombie state if something isn't working right. The defaults are kept the same as in PIIX4: both S3 and S4 are enabled by default. These can be disabled via the cmdline: ... -global ICH9-LPC.disable_s3=1 -global ICH9-LPC.disable_s4=1 Note: some guests can fake hibernation by writing a hibernate image and doing a shutdown instead of S4 if S4 isn't available; there's nothing we can do guests to stop doing this, and this patch can't affect that functionality.
