WHQL FPO optimization check for kernel video driver(s) (1.1)

This automated test validates that the stack records generated in event traces can be traversed through the video driver code. In video code, frame point optimization is turned off for debugging purposes.

This document is applicable to the following test jobs:

  • WHQL FPO optimization check for kernel video driver(s) (1.1)

  • WHQL FPO optimization check for kernel video driver(s) (1.2)

More information

When the test is run, the screen flashes a few times and it outputs an fpo_check.xml file. In the bottom of that file, it logs a pass or fail. When running, the test sets up a listener for ETW events, and then performs video work. During this time, it processes the profile event logged by the kernel, with stackwalk events enabled. For each event, it checks if the video kernel is on the stack. If so, it walks the stack looking for the operating system routine that called the video driver. If it is able to successfully find the module that called the video driver (in every case) the test passes. Otherwise, it fails.
