MODIFICATION OF 6169691Skan# THIS FILE WILL RESULT IN A NON-FUNCTIONAL T4 ADAPTER AND MAY RESULT 7169691Skan# IN PHYSICAL DAMAGE TO T4 ADAPTERS. 8169691Skan 9169691Skan# This file provides the default, power-on configuration for 4-port T4-based 10169691Skan# adapters shipped from the factory. These defaults are designed to address 11169691Skan# the needs of the vast majority of T4 customers. The basic idea is to have 12169691Skan# a default configuration which allows a customer to plug a T4 adapter in and 13169691Skan# have it work regardless of OS, driver or application except in the most 14169691Skan# unusual and/or demanding customer applications. 15169691Skan# 16169691Skan# Many of the T4 resources which are described by this configuration are 17169691Skan# finite. This requires balancing the configuration/operation needs of 18169691Skan# device drivers across OSes and a large number of customer application. 19169691Skan# 20169691Skan# Some of the more important resources to allocate and their constaints are: 21169691Skan# 1. Virtual Interfaces: 128. 22169691Skan# 2. Ingress Queues with Free Lists: 1024. PCI-E SR-IOV Virtual Functions 23169691Skan# must use a power of 2 Ingress Queues. 24169691Skan# 3. Egress Queues: 128K. PCI-E SR-IOV Virtual Functions must use a 25169691Skan# power of 2 Egress Queues. 26169691Skan# 4. MSI-X Vectors: 1088. A complication here is that the PCI-E SR-IOV 27169691Skan# Virtual Functions based off of a Physical Function all get the 28169691Skan# same umber of MSI-X Vectors as the base Physical Function. 29169691Skan# Additionally, regardless of whether Virtual Functions are enabled or 30169691Skan# not, their MSI-X "needs" are counted by the PCI-E implementation. 31169691Skan# And finally, all Physical Funcations capable of supporting Virtual 32169691Skan# Functions (PF0-3) must have the same number of configured TotalVFs in 33169691Skan# their SR-IOV Capabilities. 34169691Skan# 5. Multi-Port Support (MPS) TCAM: 336 entries to support MAC destination 35169691Skan# address matching on Ingress Packets. 36169691Skan# 37169691Skan# Some of the important OS/Driver resource needs are: 38169691Skan# 6. Some OS Drivers will manage all resources through a single Physical 39169691Skan# Function (currently PF0 but it could be any Physical Function). Thus, 40169691Skan# this "Unified PF" will need to have enough resources allocated to it 41169691Skan# to allow for this. And because of the MSI-X resource allocation 42169691Skan# constraints mentioned above, this probably means we'll either have to 43169691Skan# severely limit the TotalVFs if we continue to use PF0 as the Unified PF 44169691Skan# or we'll need to move the Unified PF into the PF4-7 range since those 45169691Skan# Physical Functions don't have any Virtual Functions associated with 46169691Skan# them. 47169691Skan# 7. Some OS Drivers will manage different ports and functions (NIC, 48169691Skan# storage, etc.) on different Physical Functions. For example, NIC 49169691Skan# functions for ports 0-3 on PF0-3, FCoE on PF4, iSCSI on PF5, etc. 50169691Skan# 51169691Skan# Some of the customer application needs which need to be accommodated: 52169691Skan# 8. Some customers will want to support large CPU count systems with 53169691Skan# good scaling. Thus, we'll need to accommodate a number of 54169691Skan# Ingress Queues and MSI-X Vectors to allow up to some number of CPUs 55169691Skan# to be involved per port and per application function. For example, 56169691Skan# in the case where all ports and application functions will be 57169691Skan# managed via a single Unified PF and we want to accommodate scaling up 58169691Skan# to 8 CPUs, we would want: 59169691Skan# 60169691Skan# 4 ports * 61169691Skan# 3 application functions (NIC, FCoE, iSCSI) per port * 62169691Skan# 8 Ingress Queue/MSI-X Vectors per application function 63169691Skan# 64169691Skan# for a total of 96 Ingress Queues and MSI-X Vectors on the Unified PF. 65169691Skan# (Plus a few for Firmware Event Queues, etc.) 66169691Skan# 67169691Skan# 9. Some customers will want to use T4's PCI-E SR-IOV Capability to allow 68169691Skan# Virtual Machines to directly access T4 functionality via SR-IOV 69169691Skan# Virtual Functions and "PCI Device Passthrough" -- this is especially 70169691Skan# true for the NIC application functionality. (Note that there is 71169691Skan# currently no ability to use the TOE, FCoE, iSCSI, etc. via Virtual 72169691Skan# Functions so this is in fact solely limited to NIC.) 73169691Skan# 74169691Skan 75169691Skan 76169691Skan# Global configuration settings. 77169691Skan# 78169691Skan[global] 79169691Skan rss_glb_config_mode = basicvirtual 80169691Skan rss_glb_config_options = tnlmapen,hashtoeplitz,tnlalllkp 81169691Skan 82169691Skan # The following Scatter Gather Engine (SGE) settings assume a 4KB Host 83169691Skan # Page Size and a 64B L1 Cache Line Size.
