      acpi-build: append description for non-hotplug · 8dcf525a
      由 Michael S. Tsirkin 提交于 
      As reported in
http://article.gmane.org/gmane.comp.emulators.qemu/253987
Mac OSX actually requires describing all occupied slots
in ACPI - even if hotplug isn't enabled.

I didn't expect this so I dropped description of all
non hotpluggable slots from ACPI.
As a result: before
commit 99fd437d (enable
hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:

Hardware -> PCI Cards:

  Card          Type                 Driver Installed  Slot
 *ethernet      Ethernet Controller  Yes               PCI Slot 2
  pci8086,2934  USB UHC              Yes               PCI Slot 29

  ethernet:
    Type:                 Ethernet Controller
    Driver Installed:     Yes
    MSI:                  No
    Bus:                  PCI
    Slot                  PCI Slot 2
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Slot                  PCI Slot 2
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

After commit 99fd437d, users get:

Hardware -> PCI Cards:

  This computer doesn't contain any PCI cards. If you installed PCI
  cards, make sure they're properly installed.

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.

To fix, append description for all occupied non hotpluggable PCI slots.

One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.

      ACPI DSDT: Make control method `IQCR` serialized · 6b9b4405
      由 Michael S. Tsirkin 提交于

    After changing the parameter from `NotSerialized` to `Serialized`, the
    remark is indeed gone and there is no size change.

    The remark was added in ACPICA version 20130517 [1] and gives the
    following explanation.

            If a thread blocks within the method for any reason, and another thread
            enters the method, the method will fail because an attempt will be
            made to create the same (named) object twice.

            In this case, issue a remark that the method should be marked
            serialized. ACPICA BZ 909.
