Marek Files 22 Gallium3D / R600g Improvements

[whitecat]

In fact, it looks like I missed some i686 libs. But it's OK now!
So I tested the current git (with the recent Vadim patch included) + this series of patch from Marek.

My config is a RV770 (HD 4850), 2 Go RAM, Pentium Dual Core E2160 @ 2,7 GHz, Fedora 17 (kernel 3.4.4 / xorg-x11-drv-ati 6.14.4 / libdrm 2.4.33).

I play ETQW at 1680*1050 and with the lowest graphics details. The FPS are roughly 30 FPS (average), which is quite playable. Even if there is some lag many times. Now the FPS can grow up to 60 FPS more often! I haven't tested very well, it depends on maps as I can see but the FPS boost is awesome!! Without visual regression. But still some lag many times.

Actually, the true Gentoo way is using the multilib-portage overlay. That way you can build all dependencies for both 32 bit and 64 bit. I do this on my laptop and it works great. No emul-linux-x86 packages required at all.

See: http://git.overlays.gentoo.org/gitwe...b-instructions

just use your normal way to build but add those two things:
- add "--enable-32-bit" (without the quotes) to the autogen.sh parameters
- set the following two environment variables: CFLAGS="-m32" and CXXFLAGS="-m32"

The gentoo way: http://www.linuxsystems.it/2012/05/g...tilib-overlay/

(I can't do it myself since I never succeed in cross-compiling mesa from 64-bit to 32-bit)

On archlinux it works like

  export CC="gcc -m32"
  export CXX="g++ -m32"
  export PKG_CONFIG_PATH="/usr/lib32/pkgconfig"
  export LLVM_CONFIG=/usr/bin/llvm-config32

    ./autogen.sh --prefix=/usr \
    --with-dri-driverdir=/usr/lib32/xorg/modules/dri \
    --with-gallium-drivers=r600 \
    --with-dri-drivers= \
   --with-egl-platforms=x11,drm \
   --enable-texture-float \
   --enable-gles1 \
   --enable-gles2 \
   --enable-egl \
   --enable-xorg \
   --enable-xa \
   --enable-vdpau \
   --enable-gallium-g3dvl \
   --enable-glx-tls \
   --enable-glu \
   --enable-gbm \
   --enable-gallium-gbm \
   --enable-shared-glapi \
   --enable-xorg \
   --enable-gallium-llvm \
   --enable-openvg \
   --enable-gallium-egl \
   --enable-32-bit \
   --libdir=/usr/lib32 \
   --enable-r600-llvm-compiler

It's dead easy with gentoo

You have already do it?
If so, please, can you tell me your ./configure option?

[FireBurn]

Nice! I hope this will boost the performance.

I hope this will commit quite quickly and that airlied or ajax puts this in koji so that I can test this within ETQW! (I can't do it myself since I never succeed in cross-compiling mesa from 64-bit to 32-bit)

Any benchmark data?
