Currently, acpi.info is an invalid link to access ACPI specification,
the new valid link is https://uefi.org/specifications.

x86/tboot: Mark tboot static

2020-04-28T09:05:44+00:00

This structure is only really used in tboot.c.  The only exception
is a single tboot_enabled check, but for that we don't need an inline
function.

ACPI: Clean up inclusions of ACPI header files

2013-12-07T00:03:14+00:00

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.

x86, acpi, tboot: Have a ACPI os prepare sleep instead of calling tboot_sleep.

2012-03-13T18:06:33+00:00

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.

KVM: VMX: enable VMXON check with SMX enabled (Intel TXT)

2010-05-19T08:36:34+00:00

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.

patch on non-X86 platforms. Remove the tboot code from generic code
init/main.c and kernel/cpu.c.
