5.2.2.3.8. PCIe0/PCIe1 MSI-X
Parameter | Value | Default Setting | Description | |
---|---|---|---|---|
Enable MSI-X/Enable VF MSI-X |
|
False | Enables or disables the MSI-X functionality. | |
Table size | 0x0–0x7FF (only values of powers of two minus 1 are valid) |
0 | Sets the number of entries in the MSI-X table. The system software reads this field to determine the MSI-X table size <n>, which is encoded as <n-1>. For example, a returned value of 2047 indicates a table size of 2048. This field is read-only. Address offset: 0x068[26:16]. |
|
Table offset | 0x0–0x1FFFFFFF | 0x00000000 | Points to the base of the MSI-X table. The lower 3 bits of the table BAR indicator (BIR) are set to zero by software to form a 64-bit qword-aligned offset This field is read-only after being programmed. |
|
Table BAR indicator | 0x0–0x5 | 0 | Specifies which one of a function's BARs, located beginning at 0x10 in the Configuration Space, is used to map the MSI-X table into memory space. This field is read-only after being programmed. |
|
PBA BAR indicator | 0x0–0x5 | 0 | Specifies the function's Base Address register, located beginning at 0x10 in the Configuration Space, that maps the MSI-X PBA into memory space. This field is read-only after being programmed. |
|
Pending bit array (PBA) offset | 0x0–0x1FFFFFFF | 0x00000000 | Used as an offset from the address contained in one of the function's Base Address registers to point to the base of the MSI-X PBA. The lower 3 bits of the PBA BIR are set to zero by software to form a 32-bit qword-aligned offset. This field is read-only after being programmed. |
|
VF Table size | 0x0–0x7FF (only values of powers of two minus 1 are valid) |
0 |
Sets the number of entries in the MSI-X table for VFs. MSI-X cannot be disabled for VFs. Set to 1 to save resources.
Note: This parameter is only available for PF.
