  • 8b48463f8   ACPI: Clean up inclusions of ACPI header files ... Browse Code »

    Replace direct inclusions of , and
    , which are incorrect, with
    inclusions and remove some inclusions of those files that aren't
    necessary.

    First of all, , and
    should not be included directly from any files that are built for
    CONFIG_ACPI unset, because that generally leads to build warnings about
    undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
    includes those files and for CONFIG_ACPI unset it
    provides stub ACPI symbols to be used in that case.

    Second, there are ordering dependencies between those files that always
    have to be met. Namely, it is required that be included
    prior to so that the acpi_pci_root declarations the
    latter depends on are always there. And which provides
    basic ACPICA type declarations should always be included prior to any other
    ACPI headers in CONFIG_ACPI builds. That also is taken care of including
    as appropriate.

  • 09f98a825   x86, acpi, tboot: Have a ACPI os prepare sleep instead of calling tboot_sleep. ... Browse Code »
    44

    The ACPI suspend path makes a call to tboot_sleep right before
    it writes the PM1A, PM1B values. We replace the direct call to
    tboot via an registration callback similar to __acpi_register_gsi.

  • cafd66595   KVM: VMX: enable VMXON check with SMX enabled (Intel TXT) ... Browse Code »

    Per document, for feature control MSR:

    Bit 1 enables VMXON in SMX operation. If the bit is clear, execution
    of VMXON in SMX operation causes a general-protection exception.
    Bit 2 enables VMXON outside SMX operation. If the bit is clear, execution
    of VMXON outside SMX operation causes a general-protection exception.

    This patch is to enable this kind of check with SMX for VMXON in KVM.
