@SYMTestCaseID GRAPHICS-EGL-0438

@SYMTestPriority 1

@SYMPREQ 2637

@SYMTestCaseDesc

    OOM test – Free VG/Egl/Sg Images while the process which owns them is terminated

@SYMTestActions

Environmental settings:

•   Image Size: w50 h50

•   List of simulated load: 0%

•   List of pixel formats

ESgPixelFormatARGB_8888

•   Client process priorities - all the same

•   Client process random parameters:

-   None

The creation of RSgImages and launching of processes is along the lines of the method outlined in GRAPHICS-EGL-RSGIMAGE_LITE-0406

    From the main process:

    For i = 0 to N

    Spawn 2 client processes A and B.

        Signal all client processes to start by use of a semaphore

        Wait until client processes exit

    If the test fails not due to the memory allocation record an error code to the log file then set a test result as a failure and skip further actions.

    End loop

    Exit

    From client process A:

    Get EGL display

    Initialize EGL

    Open RSgDriver

    Create context, pbuffer surface.

    Make pbuffer surface current for the given context  

    Loop until exit condition met

    Start loop:

Create SgImage

Create EglImage with underlying SgImage

    Create VgImage with underlying EglImage

    Exit condition – Sg/Egl/Vg image creation has failed.

End loop:

    Destroy the pbuffer surface

Log the last iteration number and exact operation which precedes a failure. 

In the environment supporting NOK_resource_profiling2 extension retrieve for further analyzes the following GPU profiling data (if available):

•   Total memory

•   Used memory

•   Process ID

•   Process used private memory

•   Process used shared memory

Make the process busy by putting it into the indefinite loop.

    From client process B:

    Wait until process A fails with the image creation.

    Terminate the process A.

@SYMTestExpectedResults

For each step from 0 to N in the main process, 

-   Image allocation failure must happen at approximately the same iteration in process A. 

    MaxIterationNumber – MinIterationNumber < Threashold, where Treashold will not 

    exceeds 5 and exact value to be defined during implementation. 

-   GPU memory usage retrieved through NOK_resource_profiling2 extension, if available, 

    is consistent and doesn’t decrease over the time. 

    MaxGPUMemoryUsage – MinGPUMemoryUsage < Threshold, where Threshold will not exceed 

    5 and exact value to be defined during implementation.
