3. Agenda Updates to existing tests New tests introduced Importance of early testing Tips & Tricks for using NDISTest Q&A

4. Updates to Existing Tests Receive Side Scaling/NetDMA Support for more than 64 processors Wake-on-LAN Pattern Multi-Path Exerciser

5. Receive-Side Scaling/NetDMA NDIS 6.20 now includes RSS revision 2 Revision 2 is required for NDIS 6.20 miniports Logo tests have been updated to use revision 2 on NDIS 6.20 miniports and fall back to revision 1 for earlier versions of NDIS Similar change were made to NetDMA tests with the new DDI to support more than 64 processors

6. Wake-On-LAN Pattern We test the following patterns for Windows 7 Logo TCP SYN packet (IPv4/IPv6) LLMNR v4/v6 NetBios name query Random data, 128-byte size Random data, random size

7. Multi-Path Exerciser (MPE) Designed to test the miniport driver reliability by stressing multiple control paths MPE spawns multiple threads for executing various tests Send-Receive, Checksum Offload, Query OID, Disable/Enable, Large-Send Offload, Standby/Resume, etc. The sequence and types of tests run by MPE is configurable and extensible. Triaging failures Review HTML log files first Reference event tracing for Windows (ETW) log files (using ETWLogReport utility) for further details

8. New Ethernet Tests Receive-Side Throttling (RST) Wake on Media Connect Low Power Offloads Virtual Machine Queues (VMQ)

9. Receive-Side Throttling What is RST? Logo requirements NDIS 6.20 miniport drivers support RST How RST logo tests work Uses Event Tracing for Windows (ETW) Pass/Fail criteria Number of packets indicated per DPC

10. Wake on Media Connect What is Wake on Media Connect? Logo requirements Wake on Media Connect is optional How the Wake on Media Connect tests work Uses new NDISTest model-based framework Available hot parameters Timer duration Pass/Fail Criteria Connecting media triggers a device wake-up

11. Low Power Protocol Offloads What are Low Power Protocol Offloads? Logo Requirements Support for this feature is optional How the tests work Test execution flow Logic exists on the support machine Pass/Fail Criteria The hardware must respond while in low power when enabled by the OS The responses must adhere to protocol standards

12. Virtual Machine Queue What is VMQ? VMQ support is optional Logo requirements if supported Support at least 4 queues with filters Support at least 16 queues with filters by 2010 MSI-X support is mandatory MAC address filtering must be supported in hardware Per-queue receive indication must be supported Look-ahead split support is optional Will be mandatory in 2010 If present, must support MaxLookAheadSplitSize >= 14 and MinLookAheadSplitSize <= 128 How VMQ logo tests work VMQ test protocol header

13. Virtual Machine Queues Continued Multiple test scripts OID handling Send/receive functionality (MAC & VLAN filtering) Lookahead split/shared memory Scalability Pass/Fail Criteria Behave according to the WDK documentation Perfect classification for unicast packets Packets indicated on the correct processor Proper lookahead split and shared memory usage

14. Importance of Early Testing Use NDISTest to verify the functionality of hardware and software Avoid costly re-spin of silicon Catch driver problems earlier in the development cycle Leverage the Logo preview releases to get familiar with the new and updated tests Get it “Logo ready” to avoid ship-stopping situations

15. Run NDISTest Standalone Less complex than using Device Test Manager Most tests run on a single machine Exception: Wake-On-LAN, Low Power Protocol Offload How-to: Copy the whole directory from below: NDISTest 6.5 \\ \tests\ \nttest\nettest\ndis\ndistest.net NDISTest 6.0 \\ \tests\ \nttest\nettest\ndis\ndistest \\ \tests\ \nttest\nettest\ndis\ndistest Run the NDISTest executable Note: NDISTest installs and configures kernel-mode drivers and must be run with administrative privileges

16. Demo: NDISTest Advanced Options

17. Call to Action Consider logo requirements when designing your hardware and device driver Test early in your development cycle Leverage NDISTest Attend other NDIS talks during DDC
