6.40.2 PCI Error Events
The following table defines the data byte formats for PCI bus-related errors logged by the BIOS.
Table 55. PCI Error Event Data Field Contents
Field IPMI Definition BIOS Specific Implementation
Generator ID 7:1 System software ID or IPMB slave
address. 1=ID is system software ID;
0=ID is IPMB slave address.
7:4 0x3 for system BIOS
3:1
0 Format revision, Revision of the data format for
OEM data bytes 2 and 3, For this revision of the
specification, set this field to 0. All other revisions are
reserved for now.
0 1=ID is system software ID
As a result, the generator ID byte will start from 0x31 and
go up to 0x3f, in increments of 2 for events logged by the
BIOS.
Sensor Type See Table 34.3, Sensor Type Codes, in the
Intelligent Management Platform Interface
Specification v1.5.
0x13 for critical interrupt
Sensor number Number of sensor that generated this event Unique value for each type of event because IPMI
specification requires it that way. This field has no other
significance. Should not be displayed to the end user if the
event is logged by BIOS. For PERRs, the sensor number
is 0xEA, for SERRs, the sensor number is 0xEB.
Type code 0x6F if event offsets are specific to the sensor 0x6F
Event Data 1 7:6 00 = unspecified byte 2
10 = OEM code in byte 2
5:4 00 = unspecified byte 3
10 = OEM code in byte 3. (BIOS will not
use encodings 01 and 11 for errors
covered by this document.)
3:0 Offset from Event Trigger for discrete
event state.
Follows the IPMI definition.
If either of the two data bytes following this do not have
any data, that byte should be set to 0xff, and the
appropriate filed in event data 1 should indicate that that it
is unspecified.
According to Table 30.3 in the Intelligent Management
Platform Interface Specification, 3:0 is 04 for PCI PERR
and 05 for PCI SERR.
Event Data 2 7:0 OEM code 2 or unspecified For format rev 0, if this byte is specified, it contains the
PCI bus number on which the failing device resides. If the
source of the PCI error cannot be determined, this byte
contains 0xff and the event data 1 byte indicates that byte
2 is unspecified.
Event Data 3 7:0 OEM code 3 or unspecified. For format rev 0, if this byte is specified, it contains the
PCI device/function address in the standard format:
7:3 Device number of the failing PCI device
2:0 PCI function number. Will always contain a zero if the
device is not a multifunction device.
If the source of the PCI error cannot be determined, this
byte contains 0xff and the event data 1 byte indicates that
byte 3 is unspecified.
