ERR<n>PFGF Error Record <n> Pseudo-fault Generation Feature Register when error record n is implemented, the node that owns error record n implements the Common Fault Injection Model Extension, and error record n is the first error record in the node 0 65534 RAS 0x800 + (64 * n) ERR<n>PFGF RO Defines which common architecturally-defined fault generation features are implemented. RAS ERR<n>FR describes the features implemented by the node. ERR<n>PFGF is a 64-bit register. 63 31 63:31 Reserved, RES0. R 30 30 30 Restartable. Support for Error Generation Counter restart mode. 0b0 The node does not support this feature. ERR<n>PFGCTL.R is RES0. 0b1 Error Generation Counter restart mode is implemented and is controlled by ERR<n>PFGCTL.R. ERR<n>PFGCTL.R is a read/write field. RO SYN 29 29 29 Syndrome. Fault syndrome injection. If ERR<n>PFGF.SYN is 1 then software can write specific values into the ERR<n>STATUS.{IERR, SERR} fields when setting up a fault injection event. The sets of values that can be written to these fields is IMPLEMENTATION DEFINED. 0b0 When an injected error is recorded, the node sets ERR<n>STATUS.{IERR, SERR} to IMPLEMENTATION DEFINED values. ERR<n>STATUS.{IERR, SERR} are UNKNOWN when ERR<n>STATUS.V is 0. 0b1 When an injected error is recorded, the node does not update the ERR<n>STATUS.{IERR, SERR} fields. ERR<n>STATUS.{IERR, SERR} are writable when ERR<n>STATUS.V is 0. RO NA 28 28 28 No access required. Defines whether this component fakes detection of the error on an access to the component or spontaneously in the fault injection state. 0b0 The component fakes detection of the error on an access to the component. 0b1 The component fakes detection of the error spontaneously in the fault injection state. RO 27 13 27:13 Reserved, RES0. MV 12 12 12 Miscellaneous syndrome. Defines whether software can control all or part of the syndrome recorded in the ERR<n>MISC<m> registers when an injected error is recorded. It is IMPLEMENTATION DEFINED which ERR<n>MISC<m> syndrome fields, if any, are updated by the node when an injected error is recorded. Some syndrome fields might always be updated by the node when an error, including an injected error, is recorded. For example, a corrected error counter might always be updated when any countable error, including a injected countable error, is recorded. If ERR<n>PFGF.MV is 1, software can write specific additional syndrome values into the ERR<n>MISC<m> registers when setting up a fault injection event. The permitted values that can be written to these registers are IMPLEMENTATION DEFINED. 0b0 When an injected error is recorded, the node might update the ERR<n>MISC<m> registers: If any syndrome is recorded by the node in the ERR<n>MISC<m> registers, then ERR<n>STATUS.MV is set to 1. Otherwise, ERR<n>STATUS.MV is unchanged. If the node always sets ERR<n>STATUS.MV to 1 when recording an injected error then ERR<n>PFGCTL.MV might be RAO/WI. Otherwise ERR<n>PFGCTL.MV is RES0. 0b1 When an injected error is recorded, the node might update some, but not all ERR<n>MISC<m> syndrome fields: If any syndrome is recorded by the node in the ERR<n>MISC<m> registers, then ERR<n>STATUS.MV is set to 1. Otherwise, ERR<n>STATUS.MV is set to ERR<n>PFGCTL.MV. ERR<n>MISC<m> syndrome fields that are not updated by the node are writable when ERR<n>STATUS.MV is 0. If the node always sets ERR<n>STATUS.MV to 1 when recording an injected error then ERR<n>PFGCTL.MV is RAO/WI. Otherwise ERR<n>PFGCTL.MV is a read/write field. RO AV 11 11 11 Address syndrome. Defines whether software can control the address recorded in ERR<n>ADDR when an injected error is recorded. If ERR<n>PFGF.AV is 1 then software can write a specific address value into ERR<n>ADDR when setting up a fault injection event. 0b0 When an injected error is recorded, the node might record an address in ERR<n>ADDR. If an address is recorded in ERR<n>ADDR, then ERR<n>STATUS.AV is set to 1. Otherwise, ERR<n>ADDR and ERR<n>STATUS.AV are unchanged. If the node always records an address and sets ERR<n>STATUS.AV to 1 when recording an injected error then ERR<n>PFGCTL.AV might be RAO/WI. Otherwise ERR<n>PFGCTL.AV is RES0. 0b1 When an injected error is recorded, the node does not update ERR<n>ADDR and does one of: Sets ERR<n>STATUS.AV to ERR<n>PFGCTL.AV. ERR<n>PFGCTL.AV is a read/write field. Sets ERR<n>STATUS.AV to 1. ERR<n>PFGCTL.AV is RAO/WI. ERR<n>ADDR is writable when ERR<n>STATUS.AV is 0. RO PN 10 10 0 Poison flag. Describes how the fault generation feature of the node sets the ERR<n>STATUS.PN status flag. This behavior replaces the architecture-defined rules for setting the ERR<n>STATUS.PN bit. 0b0 When an injected error is recorded, it is IMPLEMENTATION DEFINED whether the node sets ERR<n>STATUS.PN to 1. ERR<n>PFGCTL.PN is RES0. 0b1 When an injected error is recorded, ERR<n>STATUS.PN is set to ERR<n>PFGCTL.PN. ERR<n>PFGCTL.PN is a read/write field.
