HP SVA V2.1 System Administration Guide
• Passed with (w/X.X dB of noise)
This means that the test image was successfully generated and it was close enough to the
HP reference image that it is a match.
• ERROR: Test file never generated.
The OpenGL application didn't save the final frame to disk. Most likely, this is because the
application never ran.
• ERROR: Test and Ref files are different.(w/X.X dB of noise)
This means that although the image was generated, it was considered different than the
reference image.
• ERROR: Reference file (%s) doesn't exist
This means that the OVP doesn't have a reference file matching your Display Surface's
resolution. The test may have run correctly; but the OVP doesn't have a way of verifying
the results.
The final summary shows status for each combination of Display Surface and tile geometry:
• PASSED
The image was generated and considered a match to the reference.
• FAILED
The image was either not generated or considered different than the reference.
• NOREF
The OVP does not have a reference image that matches the resolution.
The OVP does not test render nodes and requires at least one Display Surface to run.
Example
The following example is of the OVP used to test the SVA_DS_1_1, SVA_DS_1_2, SVA_DS_1_3
Display Surfaces. Note that the image comparison noise is shown, even though the test passed.
Also note that the third test failed. In this case, that was because one of the nodes that make up
the SVA_DS_1_3 Display Surface was inoperative when the test ran.
# sva_ovp -d SVA_DS_1_1,SVA_DS_1_2,SVA_DS_1_3
