It is witnessed on some boards that the device status (as is reported by the _STA object) returns 0 while the device object is still useful for pass-through devices. The original implementation, however, assumes that only a device is a non-zero status is useful as long as the _STA object exists. This patch makes this filtering disabled by default and adds a command-line argument `--check-device-status` to enable this filtering. As disabled or non-present devices can have empty resources, the sorting algorithm is updated accordingly to gracefully handle such descriptors. This patch is added in v3 of the series.

ACRN Tools ########## The open source `Project ACRN`_ defines a device hypervisor reference stack and an architecture for running multiple software subsystems, managed securely, on a consolidated system by means of a virtual machine manager. It also defines a reference framework implementation for virtual device emulation, called the "ACRN Device Model". This folder holds the source to a number of tools that facilitate the management, debugging, profiling, and logging of multi-OS systems based on ACRN. You can find out more about Project ACRN and its set of tools on the `Project ACRN documentation`_ website. .. _`Project ACRN`: https://projectacrn.org .. _`Project ACRN documentation`: https://projectacrn.github.io/
