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?Azure Certified for IoT and the Azure IoT Device Catalog
Update Feb. 2024 - The Azure Certified Device program has concluded on February 23, 2024. This means that the Azure Certified Device catalog, along with certifications for Azure Certified Device, Edge Managed, and IoT Plug and Play will no longer be available after this date. However, the Edge Secured-core program will remain active and will be relocated to a new home at aka.ms/EdgeSecuredCoreHome. ------------------------------------------- When businesses set out on an IoT project, they have many things to consider: how the device connects to the internet, supported industry protocols. compatible sensors, and more. As IoT increasingly moves into the cloud space, one of the most important considerations is cloud compatibility. As Azure continues to grow, Azure compatibility for IoT devices is becoming a key component of the device selection process. To help with this, Microsoft has two programs to help you ensure your IoT device is compatible and discoverable: The Azure Certified for IoT program and the Azure IoT Device Catalog. The Azure Certified for IoT program is a pre-requisite for a device being included in the Azure IoT Device Catalog. There are currently three different certifications a device can achieve: IoT Devices, IoT Start Kit and IoT Edge Device. IoT Device certification covers bi-directional connectivity between the device and Azure IoT Hub. IoT Starter Kit certification builds on IoT Device certification, adding the reading of data from attached sensors, which is then sent to the cloud. IoT Edge Device certification builds on the IoT Device and Starter Kit certifications, adding Azure IoT Hub connectivity, IoT Edge runtime pre-installation, and basic device management. Once your IoT device is certified, it is qualified for inclusion in the Azure IoT Device Catalog.

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.
