1 TopicSleep and PNP Fails on ARM
Issue Summary I'm trying to certify a https://learn.microsoft.com/en-us/windows-hardware/drivers/ifs/ driver with HLK tests where the client is ARM64. Because Microsoft's documentation states that physical hardware must be used, I purchased a https://www.microsoft.com/en-us/store/configure/surface-laptop-13-inch/8mzbmmcjzqv3. All the tests pass fine, except the https://learn.microsoft.com/en-us/windows-hardware/test/hlk/testref/6bd51c1b-3dad-4a5e-b46d-98c2fe91d1aa test. Parameters used Parameter Name Value DQ DriverBinaryNames='myDriver.sys' Wpa2skAesSsid kistestssid Wpa2PskPassword password ResumeDelay 10 WDTFREMOTESYSTEM TestCycles 4 IOPeriod 1 DriverVerifierAdditionalDrivers MSDMFilt.sys FSMFApiTest TRUE LogDriverVerifierEventsAsFailure FALSE Key Observations - This test passes fine when certifying for x86_64. - For ARM64 Virtual Machine, test passes. - For ARM64 (Physical device), the test fails every time. - When targeting another driver (not my own) `WDFILTER.sys` the test fails with the same symptoms - When targeting Microsoft's sample driver [passThrough](https://github.com/microsoft/Windows-driver-samples/tree/main/filesys/miniFilter/passThrough) the test fails with the same symptoms - The tests will pass fine with the TestCycle parameter set to `3`. It always fails when set to the default `4` cycles. Errors/Warnings - HLK Studio typically states that the test failed due to an unexpected reboot - The client device's event viewer system logs show several instances of this log: Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: TE.ProcessHost.exe (6136) consumed 63349456896 bytes, MsMpEng.exe (5332) consumed 301400064 bytes, and HLKAcmengine.exe (6944) consumed 116539392 bytes. - There are more logs regarding memory usage such as: `The Client License Service (ClipSVC) failed to start due to insufficient memory resources.` - Right before the test fails, an error appears on the client where the `TE.ProcessHost.exe` process says: breakpoint reached - The CMD prompt on the client right before the test fails will often show: `crash with exception code 0xC000027B occurred in module "TextInputHost.exe"` Question The above observations and errors/warnings seem to point to either the device or the test itself being the issue. I've factory reset the laptop already and also created a fresh .vhlk to use in Hyper-V but the outcome is the same. What is the root cause of the error? Is this a known problem? Can I workaround the problem? Is the problem the test or my device?7Views0likes0Comments
