Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 92h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, subcommand = 40h |
| 5 | [7]: command response mode 0- synchronous. The BMC has a return value, and the response needs to be parsed. [6]: reserved [5:0]-segment, 1-based. For high-performance servers such as 9032, each segment indicates a 4-socket partition, and the BDF is numbered in the 4-socket system. To be compatible with earlier products and facilitate unified BMC management, the 8100 and other 4-socket or lower-socket systems do not need to distinguish BDFs by segment. Therefore, the segment is always 0. |
| 6:9 | The reserved value is used to obtain the fault capability of the specified memory address. |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion Code d6- indicates that the command is not registered with the BMC and is not supported. |
| 2:4 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 5 | [7:2]: reserved [1:0]: fault type 0x03: reserved 0x02: hard isolation 0x01: soft isolation 0x00: no fault |
| 6 | fault_type_1: memory fault isolation type. This field is valid when Byte5[1:0] is 2. [7]: Cancel the suppression of the interrupt storm. 1- Interrupt storm suppression needs to be canceled. The GPIO pin is shared with the interrupt storm suppression function. Therefore, the BIOS needs to differentiate functions based on the GPIO pin information. 0- Interrupt storm suppression does not need to be canceled. [6:0] 0- No fault information to be isolated. 1-Row fault 2-Col fault 3-Bank fault 4- chip fault 5-Rank fault 6- single-address fault Other values: reserved |
| 7:14 | Address: reserved. Indicates the address of the faulty memory. This parameter is valid when Byte5[1:0] is set to 0x01. |
| 15 | CpuId, when Byte5[1:0] |
| 16 | ChannelId, when Byte5[1:0] |
| 17 | DimmId, when Byte5[1:0] |
| 18 | Rank ID, valid when Byte5[1:0] is 2 |
| 19 | SubRank ID, valid when Byte5[1:0] is 2 |
| 20 | Device ID, valid when byte 5[1:0] is 2 |
| 21 | Bank group ID, valid when byte 5[1:0] is 2 |
| 22 | Bank ID, valid when byte 5[1:0] is 2 |
| 23:26 | Row address, valid when byte 5[1:0] is 2 |
| 27:30 | Col address, valid when byte 5[1:0] is 2 |
| 31 | [3:1] burst information. It is valid when Byte[5][1:0] is soft isolated. [0] BIOS soft isolation switch 0- disabled. If the PCLS fails, a failure message is returned and soft isolation is not performed. 1- enabled. If PCLS fails, soft isolation is performed. |
