Postponed to 6.4, and removed the blocker flag.
We will use the Vista drivers for Win7 and 2K8R2, just like we did in the past.
Yan Fixed the bug, still testing, but it is too delicate for 6.3.
Request for test:
1. Pass glitch free test
2. Test long (at least several hours) transfer scenarios (netperf and iperf).
3. Decrease "TestOnly.RXThrottle" driver parameter to 10 (from device manager -> advanced tab). Run long transfer scenarios.
1 Test out of 30 failed. In failed cases the test was complaining that we were requested to indicate only 10 packets and indicated more. According to driver printout we were never requested to indicate less than 100 packets. If this issue will detected in WHQL environment - let's gather the logs and approach MS.
During tests - test guest also as a server of iperf and netperf.
Another issue with this test - from time to time test fails with "divide by zero exception". This failure was present even before my recent changes.
This is a definite bug of the test, I suspect the server’s side.
The root cause of this zero division is that no packets are sent and no packets are received in one of 3 test iterations.
The test’s intention is to send data for 1 millisecond.
It seems that all the commands are received by server but the server definitely does not send one of batches of packets.
There are 3 batches to be sent – they’re to be received with limits of 10, 100 and 1000 packets per DPC.
This can happen on any batch – exception terminates the test.
So far,the whql passed via driver 28 (under Win7 folder) on windows 7 32/64 and windows 2008 R2 platform.
The rest testing is on going
QE run WHQL Test on virtoi-win-prewhql-29 and virtio-win-prewhql-31 ,did not this issue
Based on above ,this issue has been fixed ald .move status to VERIFIED.
