Members

       error_count Error  Count:  a  64-bit  incrementing  error  count, indicating a unique identifier for this
                   error. The error count starts at 1h, is incremented for each unique error log entry,  and  is
                   retained  across  power off conditions.  A value of 0h indicates an invalid entry; this value
                   is used when there are lost entries or when there are fewer errors than the maximum number of
                   entries  the  controller  supports.  If  the value of this field is FFFFFFFFh, then the field
                   shall be set to 1h when incremented (i.e., rolls over to 1h). Prior to NVMe  1.4,  processing
                   of incrementing beyond FFFFFFFFh is unspecified.

       sqid        Submission  Queue ID: indicates the Submission Queue Identifier of the command that the error
                   information is associated with. If the error is not specific to a  particular  command,  then
                   this field shall be set to FFFFh.

       cmdid       Command  ID:  indicates  the  Command  Identifier of the command that the error is associated
                   with. If the error is not specific to a particular command, then this field shall be  set  to
                   FFFFh.

       status_field
                   Bits  15-1:  Status  Field: indicates the Status Field for the command that completed. If the
                   error is not specific to a particular command, then this field reports  the  most  applicable
                   status value.  Bit 0: Phase Tag: may indicate the Phase Tag posted for the command.

       parm_error_location
                   Parameter  Error Location: indicates the byte and bit of the command parameter that the error
                   is associated with, if applicable. If the parameter spans multiple bytes or  bits,  then  the
                   location  indicates  the first byte and bit of the parameter.  Bits 10-8: Bit in command that
                   contained the error.  Valid values are 0 to 7.  Bits 7-0: Byte in command that contained  the
                   error.  Valid values are 0 to 63.

       lba         LBA: This field indicates the first LBA that experienced the error condition, if applicable.

       nsid        Namespace:  This field indicates the NSID of the namespace that the error is associated with,
                   if applicable.

       vs          Vendor  Specific  Information  Available:  If  there  is  additional  vendor  specific  error
                   information available, this field provides the log page identifier associated with that page.
                   A value of 0h indicates that no additional information is available. Valid values are in  the
                   range of 80h to FFh.

       trtype      Transport  Type  (TRTYPE):  indicates the Transport Type of the transport associated with the
                   error. The values in this field are the same as the TRTYPE values in the Discovery  Log  Page
                   Entry. If the error is not transport related, this field shall be cleared to 0h. If the error
                   is transport related, this field shall be set to  the  type  of  the  transport  -  see  enum
                   nvme_trtype.

       csi         Command  Set  Indicator:  This  field contains command set indicator for the command that the
                   error is associated with.

       opcode      Opcode: This field contains opcode for the command that the error is associated with.

       cs          Command Specific Information: This field contains command specific information. If used,  the
                   command definition specifies the information returned.

       trtype_spec_info
                   Transport Type Specific Information

       rsvd        Reserved: [62:42]

       log_page_version
                   This field shall be set to 1h. If set, csi and opcode will have valid values.
