tune-corei7.inc: Fix PACKAGE_EXTRA_ARCHS for corei7-32

2016-03-15T11:28:44+00:00

Change the name to core2-32 from core2.

There's no AVAILTUNES with the name core2. Make sure that we specify
the correct TUNE name so PACKAGE_EXTRA_ARCHS is expanded correctly.

[ YOCTO #9197 ]

machine/qemu: Fix OpenGL/GLX support with xserver-xorg.

2015-10-12T13:33:38+00:00

  * The Xorg server needs to load the GLX extension in order to
    enable proper OpenGL support.

  * Before this patch, glxinfo aborted with:

      root@qemux86:~# glxinfo
      name of display: :0.0
      Error: couldn't find RGB GLX visual or fbconfig

  * After this patch, it works as expected:

      root@qemux86:~# glxinfo | grep " render"
      direct rendering: Yes
      OpenGL renderer string: Software Rasterizer

tune-octeon.inc: add BASE_LIB settings

2015-08-30T11:34:07+00:00

Provide BASE_LIB settings for octeon* tunes that follow the practice of
mips64/mips64-n32 tunes (lib64 for N64 ABI, lib32 for N32 ABI).

tune-octeon.inc: correct packaging suffix

2015-08-30T11:34:07+00:00

Octeon II/III binaries can contain instructions that are not compatible
with MIPS64 processors. Thus Octeon II/III packages should go to
separate directories. Set MIPSPKGSFX_VARIANT_tune-* to Octeon-specific
values and update PACKAGE_EXTRA_ARCHS_tune-* accordingly.

arch-mips.inc: don't override TRANSLATED_TARGET_ARCH

2015-07-31T14:15:12+00:00

Currently MIPS64 N32 is broken. There is internal disagreement
between TARGET_ARCH (which doesn't contain ABIEXTENSION) and
TRANSLATED_TARGET_ARCH (which contains ABIEXTENSION). ABI is already
encoded into the TARGET_OS. ARM tunes in the same situation override
neither the TARGET_ARCH nor the TRANSLATED_TARGET_ARCH. So let's drop
this override.

arch-armv7a.inc, feature-arm-vfp.inc: add tunes for vfpv3 and vfpv3d16

This adds tunes for ARM's v3 Vector Floating Point unit for
16 and 32 bit implementation:

tune-core2.inc: set X86ARCH32 to i686 (instead of i586)

2015-07-02T22:08:27+00:00

Use i686 as TARGET_ARCH for 32bit core2 (and corei7 and atom) builds.

In most cases, i586 and i686 are equivalent values for TARGET_ARCH, however
one important exception is glibc. When configured for i686, glibc enables
optimised string functions (SSE, SSE2, etc), which are not used when
building for i586.

The benefits of i686 optimised string functions vary depending on the
application and the CPU, however in some cases the improvements are
significant. In one test, a 50% increase in FPS was seen when running the
'smashcat' benchmark [1] in a qtwebkit browser on an Intel Atom based SoC.
The gain seems to comes from a 3x improvement in memcpy performance when
copying graphics buffer lines (5120 bytes, or 1280 x 4 bytes/pixel), from
the CPU to GPU. Note that very large memcpy's (e.g. 32MB) on the same
machine show no particular performance increase between i586 and i686.

  [1] http://www.smashcat.org/av/canvas_test/

Warning: The change in TARGET_ARCH means that _i586 architecture specific
over-rides will no longer take effect. Both oe-core and meta-oe have been
updated to replace _i586 over-rides with _x86, however other layers may
still need review and updating.
