Re: [Mesa-dev] glxgears is faster but 3D render is so slow

Tue, 12 Mar 2013 07:59:29 -0700

Well, the Xlib/swrast driver does everything in software, unlike a DRI driver which does most things with the GPU. Xlib will always be slower. 

The gallium llvmpipe driver should be quite a bit faster.
Just install LLVM first, then reconfigure/rebuild Mesa, set your LD_LIBRARY_PATH to the lib/gallium/ directory and you should get llvmpipe.

Hi Brian,

You are right, setting MESA_GLX_DEPTH_BITS to 24 bit does not change
anything. So why Xlib has such poor performance to run following
application?

http://www.cgl.ucsf.edu/chimera/download.html

Are there any other things I can try to make Xlib driver performance
equals to DRI?

Thank you.

Kind regards,

Jupiter

I don't think you have to worry about the difference in buffer depths.

If you really want a 24-bit depth buffer you can do 'export
MESA_GLX_DEPTH_BITS=24'

Hi Brian,

Please see attached config.log. Le me make a correction, I mean 32
buffer bit and 24 depth bit in DRI and 24 buffer bit and 16 bit depth
bit in xlib driver. Will it make difference if setting 32 buffer bit
and 24 depth bit for xlib? If so, how to do it?

Thank you.

Kind regards.

Hi Brian,

I finally built Mesa with configuration "--enable-xlib-glx
--disable-dri --enable-gallium-llvm --with-llvm-shared-libs", with
dependencies of llvm and drm. It does not work either, please see
following glxinfo. Please let me know if my configuration is not
correct, or if there are any other ways I can try to make it work.

Hi Brian,

Thanks for your response, please see following glxinfo. I am currently
building the LLVM, seems need hours to complete it. Is it correct to
reconfigure/rebuild Mesa with "--enable-xlib-glx --disable-dri

What does 'glxinfo' say with this configuration?  I'm guessing you're
using the softpipe driver which is meant for correctness, not speed.
For speed, you want the llvmpipe driver.  Install LLVM on your system
first then reconfigure/rebuild Mesa.

Hi,

It seems using xlib-glx stopped 3D rotating. If I built mesa 9.1
using
DRI in my local machine, it can rotate 3D picture. Is there anyway
workaround to use xlib-glx for 3D applications?

Thank you.

Kind regards.

Hi,

I built mesa 9.1 with following configuration:

--enable-xlib-glx --disable-dri --with-gallium-drivers=swrast
--enable-osmesa --with-osmesa-bits=32

The mesa package is used by TurboVNC, so xlib glx has to be used
instead of DRI. It works well to gain faster speed in glxgears, but
it
has huge problems to render a 3D modules in an application of
CHIMERA.

The thing puzzled me is when I use CentOS system provided Mesa 7.11,
the CHIMERA 3D picture rotation works fine despite the glxgears is
very slow (250 FPS).

I am not clear that the slower 3D rendering in my built mesa is
because the DRI or I may miss some configurations. Appreciate any
advice.

Thank you.

Kind regards.

Jupiter
