2013-03-04OvmfPkg: report support for the PIIX3 reset register in the FADTjljusten
The value to be written corresponds to hard reset, which is what the ACPI spec prescribes.

2013-03-04OvmfPkg: upgrade the FADT to ACPI 2.0 without functional changesjljusten
This conversion cannot be split very well into smaller patches.

According to the spec, "platforms should set this field to zero but field values of one are also allowed to maintain compatibility with ACPI 1.0". We're setting it to zero. About Preferred_PM_Profile (taking the place of an 1.0 reserved field), the specification says: This field is set by the OEM to convey the preferred power management profile to OSPM. OSPM can use this field to set default power management policy parameters during OS installation. >From <MdePkg/Include/IndustryStandard/Acpi20.h>: #define EFI_ACPI_2_0_PM_PROFILE_UNSPECIFIED 0 #define EFI_ACPI_2_0_PM_PROFILE_DESKTOP 1 #define EFI_ACPI_2_0_PM_PROFILE_MOBILE 2 #define EFI_ACPI_2_0_PM_PROFILE_WORKSTATION 3 #define EFI_ACPI_2_0_PM_PROFILE_ENTERPRISE_SERVER 4 #define EFI_ACPI_2_0_PM_PROFILE_SOHO_SERVER 5 #define EFI_ACPI_2_0_PM_PROFILE_APPLIANCE_PC 6 For a virtual machine, "unspecified" is the best choice. > UINT16 SciInt; > UINT32 SmiCmd; > UINT8 AcpiEnable; > UINT8 AcpiDisable; > UINT8 S4BiosReq; > - UINT8 Reserved2; > + UINT8 PstateCnt; We've been already treating this field as PSTATE_CNT.

2013-03-04OvmfPkg: fold macros of unsupported GPE1 register block into Facp.aslcjljusten
In the next patch we're going to specify Extended Addresses of register blocks in Generic Address Structure format. The GAS is easy to fill if we want to posit either "unsupported" (all zero) or a given address in a specific address space. However deriving "unsupported" just from a macro expanding to zero is unwieldy, so let's avoid the need.
