This section provides information on general registry keys that affect Mellanox driver operation.
Value Name | Default Value | Description |
MaxNumRssCpus | 4 | The number of CPUs that participate in the RSS. The Mellanox adapter can open multiple receive rings, each ring can be processed by a different processor. When RSS is disabled, the system opens a single Rx ring. The Rx ring number that is configured should be powered of two and less than the number of processors on the system. Value Type: DWORD The valid values are 1 up to number of processors on the system. |
RssBaseCpu | 1 | The CPU number of the first CPU that the RSS can use. NDIS uses the default value of 0 for the base CPU number, however this value is configurable and can be changed. The Mellanox adapter reads this value from registry and sets it to NDIS on driver start-up. Value Type: DWORD The valid values are 0 up to the number of processors on the system. |
CheckFwVersion | 1 | Configures the Mellanox driver to skip validation of the FW compatibility to the driver version. Skipping this check-up is not recommended and can cause unexpected behavior. It can be used for testing purposes only. Value Type: DWORD The valid values are:
|
MaximumWorkingThreads | 2 | The number of working threads which can work simultaneously on receive polling. By default, the Mellanox driver creates a working thread for each Rx rings if polling or adaptive receive completion is set. Value Type: DWORD The valid values are 1 up to number of Rx rings. |
