6.2.4.3. PCIe0 MSI-X
Parameter | Value | Description |
---|---|---|
Enable MSI-X |
On / Off |
When On, adds the MSI-X capability structure, with the parameters shown below. |
Table size |
15 |
System software reads this field to determine the MSI-X table size <n>, which is encoded as <n-1>. |
Table offset |
0x0000000000020000 |
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 |
0 |
Specifies which one of a function's base address registers, located beginning at 0x10 in the Configuration Space, maps the MSI-X table into memory space. This field is read-only. |
Pending bit array (PBA) offset |
0x0000000000030000 |
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 |
PBA BAR indicator |
0 |
Specifies the function Base Address registers, located beginning at 0x10 in Configuration Space, that maps the MSI-X PBA into memory space. This field is read-only in the MSI-X Capability Structure. |
VF Table size |
0 |
Sets the number of entries in the MSI-X table for PF0's VFs. MSI-X cannot be disabled for VF. Set to 1 to save resources. |
Parameter | Value | Description |
---|---|---|
Enable VF MSI-X | On / Off | When On, adds the MSI-X capability structure to the VF, with the parameters shown below. |
Table size | 15 | System software reads this field to determine the VF MSI-X table size <n>, which is encoded as <n-1>. |
Table offset | 0x0000000000020000 | Points to the base of the VF 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 | 0 | Specifies which one of a function's base address registers, located beginning at 0x10 in the Configuration Space, maps the VF MSI-X table into memory space. This field is read-only. |
Pending bit array (PBA) offset | 0x0000000000030000 | Used as an offset from the address contained in one of the function's Base Address registers to point to the base of the VF 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. |
PBA BAR indicator | 0 | Specifies the function Base Address registers, located beginning at 0x10 in Configuration Space, that maps the VF MSI-X PBA into memory space. This field is read-only in the MSI-X Capability Structure. |
