More Information

The TDR2 test validates that the video driver functions correctly when GPU workloads, as direct memory access (DMA) packets, are processed for longer periods than expected or wanted.

Terms that you'll find in the titles of the jobs for this test include:

  • Interactive (standard behavior). The application doesn't schedule larger workloads. TDRs (at 2 seconds) are expected if the workload is too big.

  • NonInteractive (new functionality). The application may schedule workloads that take longer than 2 seconds to finish. A typical scenario here is a Compute application that will run a large calculation in the background. With NonInteractive workloads, the scheduler will not interrupt its processing if no other GPU work must be performed at the same time.

  • PoliceDdi. When resets occur, the test jobs track all device driver interface (DDI) calls to measure a reasonable responsiveness from the driver and hardware. Generally, DDI calls that take over a quarter second are flagged as excessive.

These test jobs also exercise engine-reset functionality where appropriate. The older TDR functionality performed an adapter-wide reset, whereas the new TDR functionality attempts an engine reset before an adapter-wide reset.

The testing process requires running multiple binaries at the same time. One or more applications generate workloads while another application monitors the effect that these workloads have on the system. The command lines that the test jobs use to start the applications allow for cross-process communication, so running the test jobs in scripts is the preferred technique.

Note  

You must run all test jobs by using administrator credentials. All the test binaries generate log files that shouldn't contain test failures.

 

Command syntax

TDR2 test jobs are divided into these areas:

  • Long Running Graphics Packet test jobs

  • Long Running Compute Packets test jobs

  • Multiple TDR Lockout and Recovery test jobs

  • Uninterrupted Application test job

  • Large Payload Penalty test jobs

  • Miscellaneous test job

Scripts control actions that occur during individual test jobs. The following tables list these scripts. If you're manually reproducing the test jobs, you must run these scripts.

Note  

For test combination command lines, see individual script files.

 

The following Long Running Graphics Packet test jobs run test situations that should and shouldn't cause a TDR, based on whether the test acts like an interactive application. These test jobs also make sure that DDI calls respond in a reasonable amount of time.
