2015-02-26acpi: introduce AML composer aml_append()Igor Mammedov
Adds for dynamic AML creation, which will be used for piecing ASL/AML primitives together and hiding from user/caller details about how nested context should be closed/packed leaving less space for mistakes and necessity to know how AML should be encoded, allowing user to concentrate on ASL representation instead. For example it will allow to create AML like this: init_aml_allocator(); ... Aml *scope = aml_scope("PCI0") Aml *dev = aml_device("PM") aml_append(dev, aml_name_decl("_ADR", aml_int(addr))) aml_append(scope, dev); ... free_aml_allocator(); Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

2015-02-26acpi, ich9: Add unplug cb for ich9.Tang Chen
Memory and CPU hot unplug are both asynchronous procedures. When the unplug operation happens, unplug request cb is called first. And when guest OS finished handling unplug, unplug cb will be called to do the real removal of device. This patch adds hotunplug cb to ich9, which memory and CPU hot unplug will use it.

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.

... it will be used to abstract generic ACPI bits from device that implements ACPI interface. ACPIOSTInfo type is used for passing-through raw _OST event/status codes reported by guest OS to a management layer. It lets management tools interpret values as specified by ACPI spec if it is interested in it. QEMU doesn't encode these values as enum, since it doesn't need to handle them and it allows interface to scale well without any changes in QEMU while guest OS and management evolves in time.

PIIX created a made-up value for the UP register since it was read by guest 32 times for each interrupt. There's no reason to do this for the new PCIHP: register is only read once for each interrupt, so clean up code by making read act as an interrupt acknowledgement: the new UP register clear on read. In this way we cut down the number of bus rescans by a factor of 32, and drop a bunch of code that's now unused. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Add ACPI based PCI hotplug library with bridge hotplug support. Design - each bus gets assigned "bsel" property. - ACPI code writes this number to a new BNUM register, then uses existing UP/DOWN registers to probe slot status; to eject, write number to BNUM register, then slot into existing EJ. The interface is actually backwards-compatible with existing PIIX4 ACPI (though not migration compatible). This is split out from PIIX4 codebase so we can reuse it for Q35 as well.
