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.

Field Documentation

struct { ... } EFI_HEALTH_FLAGS::Bits

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

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

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.

Reserved 13 bits.

Reserved 12 bits.

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

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.

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