Detailed Description

EFI_HEALTH_FLAGS Contains information generated by microcode, hardware, and/or the Itanium processor PAL code about the state of the processor upon reset.

Definition at line 34 of file SecPlatformInformation.h.

Field Documentation

◆ FloatingPointUnavailable

UINT32 EFI_HEALTH_FLAGS::FloatingPointUnavailable

A 1-bit field. If set to 1, this indicates that the floating point unit is not available.

Definition at line 64 of file SecPlatformInformation.h.

◆ Ia32ExecutionUnavailable

UINT32 EFI_HEALTH_FLAGS::Ia32ExecutionUnavailable

A 1-bit field. If set to 1, this indicates that IA-32 execution is not available.

Definition at line 59 of file SecPlatformInformation.h.

◆ MiscFeaturesUnavailable

UINT32 EFI_HEALTH_FLAGS::MiscFeaturesUnavailable

A 1-bit field. If set to 1, this indicates miscellaneous functional failure other than vm, ia, or fp. The test status field provides additional information on test failures when the State field returns a value of performance restricted or functionally restricted. The value returned is implementation dependent.

Definition at line 73 of file SecPlatformInformation.h.

◆ Reserved1


Reserved 13 bits.

Definition at line 49 of file SecPlatformInformation.h.

◆ Reserved2


Reserved 12 bits.

Definition at line 77 of file SecPlatformInformation.h.

◆ Status


A 2-bit field indicating self-test state after reset.

Definition at line 39 of file SecPlatformInformation.h.

◆ Tested


A 1-bit field indicating whether testing has occurred. If this field is zero, the processor has not been tested, and no further fields in the self-test State parameter are valid.

Definition at line 45 of file SecPlatformInformation.h.

◆ Uint32


Definition at line 79 of file SecPlatformInformation.h.

◆ VirtualMemoryUnavailable

UINT32 EFI_HEALTH_FLAGS::VirtualMemoryUnavailable

A 1-bit field. If set to 1, this indicates that virtual memory features are not available.
