MODIFICATION OF 6# THIS FILE WILL RESULT IN A NON-FUNCTIONAL T4 ADAPTER AND MAY RESULT 7# IN PHYSICAL DAMAGE TO T4 ADAPTERS. 8 9# This file provides the default, power-on configuration for 4-port T4-based 10# adapters shipped from the factory. These defaults are designed to address 11# the needs of the vast majority of T4 customers. The basic idea is to have 12# a default configuration which allows a customer to plug a T4 adapter in and 13# have it work regardless of OS, driver or application except in the most 14# unusual and/or demanding customer applications. 15# 16# Many of the T4 resources which are described by this configuration are 17# finite. This requires balancing the configuration/operation needs of 18# device drivers across OSes and a large number of customer application. 19# 20# Some of the more important resources to allocate and their constaints are: 21# 1. Virtual Interfaces: 128. 22# 2. Ingress Queues with Free Lists: 1024. PCI-E SR-IOV Virtual Functions 23# must use a power of 2 Ingress Queues. 24# 3. Egress Queues: 128K. PCI-E SR-IOV Virtual Functions must use a 25# power of 2 Egress Queues. 26# 4. MSI-X Vectors: 1088. A complication here is that the PCI-E SR-IOV 27# Virtual Functions based off of a Physical Function all get the 28# same umber of MSI-X Vectors as the base Physical Function. 29# Additionally, regardless of whether Virtual Functions are enabled or 30# not, their MSI-X "needs" are counted by the PCI-E implementation. 31# And finally, all Physical Funcations capable of supporting Virtual 32# Functions (PF0-3) must have the same number of configured TotalVFs in 33# their SR-IOV Capabilities. 34# 5. Multi-Port Support (MPS) TCAM: 336 entries to support MAC destination 35# address matching on Ingress Packets. 36# 37# Some of the important OS/Driver resource needs are: 38# 6. Some OS Drivers will manage all resources through a single Physical 39# Function (currently PF0 but it could be any Physical Function). Thus, 40# this "Unified PF" will need to have enough resources allocated to it 41# to allow for this. And because of the MSI-X resource allocation 42# constraints mentioned above, this probably means we'll either have to 43# severely limit the TotalVFs if we continue to use PF0 as the Unified PF 44# or we'll need to move the Unified PF into the PF4-7 range since those 45# Physical Functions don't have any Virtual Functions associated with 46# them. 47# 7. Some OS Drivers will manage different ports and functions (NIC, 48# storage, etc.) on different Physical Functions. For example, NIC 49# functions for ports 0-3 on PF0-3, FCoE on PF4, iSCSI on PF5, etc. 50# 51# Some of the customer application needs which need to be accommodated: 52# 8. Some customers will want to support large CPU count systems with 53# good scaling. Thus, we'll need to accommodate a number of 54# Ingress Queues and MSI-X Vectors to allow up to some number of CPUs 55# to be involved per port and per application function. For example, 56# in the case where all ports and application functions will be 57# managed via a single Unified PF and we want to accommodate scaling up 58# to 8 CPUs, we would want: 59# 60# 4 ports * 61# 3 application functions (NIC, FCoE, iSCSI) per port * 62# 8 Ingress Queue/MSI-X Vectors per application function 63# 64# for a total of 96 Ingress Queues and MSI-X Vectors on the Unified PF. 65# (Plus a few for Firmware Event Queues, etc.) 66# 67# 9. Some customers will want to use T4's PCI-E SR-IOV Capability to allow 68# Virtual Machines to directly access T4 functionality via SR-IOV 69# Virtual Functions and "PCI Device Passthrough" -- this is especially 70# true for the NIC application functionality. (Note that there is 71# currently no ability to use the TOE, FCoE, iSCSI, etc. via Virtual 72# Functions so this is in fact solely limited to NIC.) 73# 74 75 76# Global configuration settings. 77# 78[global] 79 rss_glb_config_mode = basicvirtual 80 rss_glb_config_options = tnlmapen,hashtoeplitz,tnlalllkp 81 82 # The following Scatter Gather Engine (SGE) settings assume a 4KB Host 83 # Page Size and a 64B L1 Cache Line Size.
