Hi, Here is the 2nd version of the patch series. The main change is that the new code is limited to POWER8 Little-Endian machines, due to a special compiler flag (power8-vector) that must bu turned on but creates code that can't run on POWER7 machines.
As only POWER8 has an LE mode (ppc64le), the code can be encomposed with: #if defined(_ARCH_PWR8) && defined(PIPE_ARCH_LITTLE_ENDIAN) and because an LE binary can't be run on BE machine anyway, we can safely enable this code by default for ppc64le architecture. A few more changes are detailed in each commit message. Thanks, - Oded Oded Gabbay (5): configure.ac: Detect if running on POWER8 arch llvmpipe: add POWER8 portability file - u_pwr8.h llvmpipe: Optimize do_triangle_ccw for POWER8 llvmpipe: Optimize BUILD_MASK(_LINEAR) for POWER8 llvmpipe: Optimize lp_rast_triangle_32_3_16 for POWER8 configure.ac | 55 +++++ src/gallium/auxiliary/util/u_pwr8.h | 310 ++++++++++++++++++++++++++++ src/gallium/drivers/llvmpipe/lp_rast_tri.c | 290 ++++++++++++++++++++++---- src/gallium/drivers/llvmpipe/lp_setup_tri.c | 100 +++++++++ 4 files changed, 715 insertions(+), 40 deletions(-) create mode 100644 src/gallium/auxiliary/util/u_pwr8.h -- 2.5.0 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
