* x86, acpi, tboot: Have a ACPI os prepare sleep instead of calling tboot_sleep.Tang Liang2012-03-131-1/+0
| | | | | | | | | | | | | | | | | 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.

Wysocki <rjw@sisk.pl> [v1: Added __attribute__ ((unused))] [v2: Introduced a wrapper instead of changing tboot_sleep return values] [v3: Added return value AE_CTRL_SKIP for acpi_os_sleep_prepare] Signed-off-by: Tang Liang <liang.tang@oracle.com> [v1: Fix compile issues on IA64 and PPC64] [v2: Fix where __acpi_os_prepare_sleep==NULL and did not go in sleep properly] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
* KVM: VMX: enable VMXON check with SMX enabled (Intel TXT)Shane Wang2010-05-191-0/+1
| | | | | | | | | | | | | | 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.

* x86, intel_txt: clean up the impact on generic code, unbreak non-x86Shane Wang2009-09-011-0/+162
Move tboot.h from asm to linux to fix the build errors of intel_txt patch on non-X86 platforms. Remove the tboot code from generic code init/main.c and kernel/cpu.c. Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
