All rights reserved. # # DO NOT MODIFY THIS FILE UNDER ANY CIRCUMSTANCES. MODIFICATION OF # THIS FILE WILL RESULT IN A NON-FUNCTIONAL T4 ADAPTER AND MAY RESULT # IN PHYSICAL DAMAGE TO T4 ADAPTERS. # This file provides the default, power-on configuration for 4-port T4-based # adapters shipped from the factory. These defaults are designed to address # the needs of the vast majority of T4 customers. The basic idea is to have # a default configuration which allows a customer to plug a T4 adapter in and # have it work regardless of OS, driver or application except in the most # unusual and/or demanding customer applications. # # Many of the T4 resources which are described by this configuration are # finite. This requires balancing the configuration/operation needs of # device drivers across OSes and a large number of customer application. # # Some of the more important resources to allocate and their constaints are: # 1. Virtual Interfaces: 128. # 2. Ingress Queues with Free Lists: 1024. PCI-E SR-IOV Virtual Functions # must use a power of 2 Ingress Queues. # 3. Egress Queues: 128K. PCI-E SR-IOV Virtual Functions must use a # power of 2 Egress Queues. # 4. MSI-X Vectors: 1088. A complication here is that the PCI-E SR-IOV # Virtual Functions based off of a Physical Function all get the # same umber of MSI-X Vectors as the base Physical Function. # Additionally, regardless of whether Virtual Functions are enabled or # not, their MSI-X "needs" are counted by the PCI-E implementation. # And finally, all Physical Funcations capable of supporting Virtual # Functions (PF0-3) must have the same number of configured TotalVFs in # their SR-IOV Capabilities. # 5. Multi-Port Support (MPS) TCAM: 336 entries to support MAC destination # address matching on Ingress Packets. # # Some of the important OS/Driver resource needs are: # 6. Some OS Drivers will manage all resources through a single Physical # Function (currently PF0 but it could be any Physical Function). Thus, # this "Unified PF" will need to have enough resources allocated to it # to allow for this. And because of the MSI-X resource allocation # constraints mentioned above, this probably means we'll either have to # severely limit the TotalVFs if we continue to use PF0 as the Unified PF # or we'll need to move the Unified PF into the PF4-7 range since those # Physical Functions don't have any Virtual Functions associated with # them. # 7. Some OS Drivers will manage different ports and functions (NIC, # storage, etc.) on different Physical Functions. For example, NIC # functions for ports 0-3 on PF0-3, FCoE on PF4, iSCSI on PF5, etc. # # Some of the customer application needs which need to be accommodated: # 8. Some customers will want to support large CPU count systems with # good scaling. Thus, we'll need to accommodate a number of # Ingress Queues and MSI-X Vectors to allow up to some number of CPUs # to be involved per port and per application function. For example, # in the case where all ports and application functions will be # managed via a single Unified PF and we want to accommodate scaling up # to 8 CPUs, we would want: # # 4 ports * # 3 application functions (NIC, FCoE, iSCSI) per port * # 8 Ingress Queue/MSI-X Vectors per application function # # for a total of 96 Ingress Queues and MSI-X Vectors on the Unified PF. # (Plus a few for Firmware Event Queues, etc.) # # 9. Some customers will want to use T4's PCI-E SR-IOV Capability to allow # Virtual Machines to directly access T4 functionality via SR-IOV # Virtual Functions and "PCI Device Passthrough" -- this is especially # true for the NIC application functionality. (Note that there is # currently no ability to use the TOE, FCoE, iSCSI, etc. via Virtual # Functions so this is in fact solely limited to NIC.) # # Global configuration settings. # [global] rss_glb_config_mode = basicvirtual rss_glb_config_options = tnlmapen,hashtoeplitz,tnlalllkp # The following Scatter Gather Engine (SGE) settings assume a 4KB Host # Page Size and a 64B L1 Cache Line Size.
