Summary: OSMesa Gallium llvmpipe VTK Test Failures
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: git
Component: Mesa core
Product: Mesa
Since OSMesa switched to Gallium and defaults to the llvmpipe driver VTK's test
:
vtkRenderingOpenGLCxx-TestTransformCoordinateUseDouble
has been failing.
This test has a page on VTK's dashboard :
http://open.cdash.org/testSummary.php?project=11&name=vtkRenderingOpenGLCxx-TestTransformCoordinateUseDouble&date=2013-04-12
The take home message is that the test passes in my OSMesa-9.1.1 build which
uses the Mesa Offscreen driver and fails on all of the builds that use the
llvmpipe driver.
I played around with different drivers by setting GALLIUM_DRIVER to one
llvmpipe or softpipe and used on screen and off screen builds of VTK. I set
LIBGL_ALWAYS_SOFTWARE to get one of the software drivers or left it unset to
use the nouveau driver on my on screen build. What I got was :
OSMesa-9.1.1 offscreen pass
OSMesa-git softpipe pass
OSMesa-git llvmpipe fail
Mesa-9.1.1 softpipe pass
Mesa-9.1.1 nouveau pass
Mesa-9.1.1 llvmpipe fail
Mesa-git softpipe pass
Mesa-git nouveau pass
Mesa-git llvmpipe fail
which says that llvmpipe is the issue.
I did a bunch of apitraces and put them here :
