Sleep 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?The IoT Show: Unboxing the Vision AI DevKit
The Vision AI DevKit appears in the latest 'The IoT Show' in an unboxing demo with Mahesh Yadev and Olivier Bloch. The full video is embedded at the bottom of this post. From the show description - Mahesh Yadav, Software Engineer on the Intelligent Edge team, joins the IoT Show to unbox the Microsoft Vision AI DevKit (aka.ms/iotshow/visionaidevkit), a smart camera for the intelligent edge. The developer kit uses the Qualcomm's Vision Intelligence 300 Platform which uniquely runs machine learning with hardware acceleration delivering results in milliseconds which is perfect for connected car or connected factory scenarios where you need low latency as well as support offline scenarios. In this episode, you will see how easy it is to bring up AI on the edge with Azure IoT Edge and Azure Machine Learning. The DevKit includes a sample AI model that identifies 183 objects including people, laptops, chairs and more. The highlight of the show is a real-time camera demo that asserts that both Mahesh and Olivier really are people.Enhancing automatic module deployments to devices through Azure IoT Edge
Azure IoT Edge has today released several enhancements to improve remote device management and edge device workload update tasks. Layered deployments give you the ability to independently deploy different combinations of modules to otherwise similar hardware, without requiring the creation of an automatic Deployment for every unique hardware configuration. Improved UI for automatic deployments allows for browsing and selection of Microsoft Azure Marketplace modules from within the create deployment experience. There are also new controls for setting routes and module twin properties. Automatic device management has gained automatic configuration for module twins helps to automate some repetitive tasks, similar to what is already available for for managing automatic device configurations.

Security in the IoT and Intelligent Edge hardware projects is becoming the highest priority item to close during the hardware planning phase. Devices incorporating cellular technologies have a higher security concern than others. At Qualcomm's 5G Summit in Barcelona, Spain (October 15th), Qualcomm announced it is developing the first cellular chip optimized and certified for Azure Sphere. The chipset for IoT will include hardware-level security, pre-configured with Azure Sphere and automatically connecting to Azure Sphere security cloud services. Read the complete release from Qualcomm and watch for further details coming later. Qualcomm Technologies to Enhance Secure Cellular Connectivity Solutions with Microsoft Azure Sphere for the IoTHands-on: Learn how to deliver OTA firmware updates with Azure IoT Hub
IoT and intelligent Edge devices deployed in the field sometimes require firmware updates to improve security or resilience. It is often impractical to physically visit every single device and manually apply new firmware, not to mention time consuming. Azure IoT Hub offers an automatic device management feature to help you roll out updates quickly and easily over the air (OTA). You can get familiar with how this is done by using an MXChip IoT DevKit by following the tutorial in GitHub Update IoT DevKit firmware OTA (Over-the-Air) through Azure IoT Hub Automatic Device Management. If you already have an MXChip IoT DevKit, give it a try today! If you need one, purchase a DevKit from SeeedStudio.Getting the November 2019 release of Windows 10 ready for release
