Error Reporting and Handling Intel® Server Board SE7520BD2 Technical Product Specification
126 Revision 1.3
5.4.3.2 PCI Error Events
Table 63. PCI Error Events
Field IPMI Definition Intel® Server Board SE7520BD2 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 30.3 in [IPMI_1]. 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.
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.
Follow 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 [IPMI_1], 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.
Table 64. Examples of Event Data Field Contents for PCI Errors
Error Type Event Data 1 Event Data 2 Event Data 3
PCI PERR, failing device is not known 04 0xFF 0xFF
PCI SERR, failing device is not known 05 0xFF 0xFF
PCI PERR, device 3, function 1 on PCI bus 5 reported the error 0xA4 0x05 0x19
(Bits 7:3 = 03
Bits 2:0 = 01)
An unknown device on PCI bus 0 reported the SERR 0x85 0x00 0xFF
