2016-06-12mips: add tunes for (some) 24K coresAndré Draszik
- add 24kc big and little endian, which is based on mips32r2 w/o FPU - add 24kec which is 24kc + DSP - both can have the MIPS16e ASE enabled in their tunes Signed-off-by: André Draszik <adraszik@tycoint.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
2016-06-12mips: add a tune for using MIPS16e ASE instructionsAndré Draszik
The MIPS16e instruction set still has to be enabled by setting MIPS_INSTRUCTION_SET = 'mips16e' in e.g. distro.conf and can be disabled on a per-recipe basis as needed. This is a similar approach as is available on ARM for Thumb support. Note that contrary to the ARM Thumb support in OE, we do add a new OVERRIDE (mips16e), as there are some recipes in OE that need to be compiled slightly differently if mips16e mode is requested.

2016-05-14feature-arm-vfp.inc: fix overzealous ARMPKGSFX_FPU modificationAndré Draszik
Since commit 972b4fc (feature-arm-neon.inc: restore vfpv3-d16 support) we're replacing _all_ dashes (-) in ARMPKGSFX_FPU, which is causing problems for all legitimate uses of the dash as TUNE_PKGARCH doesn't have the right value anymore: E.g. on raspberrypi2: ERROR: OE-core's config sanity checker detected a potential misconfiguration. Either fix the cause of this error or at your own risk disable the checker (see sanity.conf). Following is the list of potential problems / advisories: Error, the PACKAGE_ARCHS variable (all any noarch armv5hf-vfp armv5thf-vfp armv5ehf-vfp armv5tehf-vfp armv6hf-vfp armv6thf-vfp armv7ahf-vfp armv7at2hf-vfp armv7vehf-vfp armv7vet2hf-vfp armv7vehf-neon armv7vet2hf-neon armv7vehf-neon-vfpv4 armv7vet2hf-neon-vfpv4 cortexa7hf-vfp cortexa7hf-neon cortexa7hf-neon-vfpv4 cortexa7t2hf-vfp cortexa7t2hf-neon cortexa7t2hf-neon-vfpv4 raspberrypi3) for DEFAULTTUNE (cortexa7thf-neon-vfpv4) does not contain TUNE_PKGARCH (cortexa7hf-neonvfpv4).

2016-05-11feature-arm-neon.inc: restore vfpv3-d16 supportAndré Draszik
Commit 6661718 (feature-arm-{neon,vfp}.inc: refactor and fix issues) effectively changed the gcc -mfpu= option from -mfpu=vfpv3-d16 to -mfpu=vfpv3d16, which gcc doesn't understand. Restore the original value. After doing that, we also need to adjust ARMPKGSFX_FPU which should contain the same value without dash '-' as it is used that way throughout.

If tune-corei7 is in use then the target binaries may contain instructions that qemu-x86-64 can't execute by default, resulting in errors on rootfs construction: NOTE: Running intercept scripts: NOTE: > Executing update_font_cache intercept ... qemu: uncaught target signal 4 (Illegal instruction) - core dumped In this case the instruction is popcnt, part of SSE4.2, so tell Qemu to emulate the CPU that the tune targets (in this case, Nehalem).

2016-01-30gcc, qemuppc: Explicitly disable forcing SPE flagsKhem Raj
G4 does not have SPE, so we make that explicit in the tune files and since we emulate G4 when building Qemu, we ensure it for qemuppc as well. GCC config for powerpc-linux is made to include SPE by default which is equivalent if the tripet was powerpc-linux*spe, this forces gcc to configure assembler to enable -mspe by default, when we do that then the kernel fails to compile with binutils 2.26, since newer assembler is smart to detect the tlbia instructions are not compatible with SPE and hence the kernel build breaks rightly. We configure the kernel for G4 as well where it enables tlbia instrucitons rightly so because it thinks its being configured for power4. So we keep the options but do not force -mspe down to assembler as default. Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* respect all 4 vfp options ('vfp', 'vfpv3d16', 'vfpv3', 'vfpv4') when setting -mfloat-abi and ARMPKGSFX_EABI, without this change it wasn't possible to use call-convention hard together with vfpv4 * move 'vfpv3d16', 'vfpv3', 'vfpv4' support from feature-arm-vfp.inc to feature-arm-neon.inc the main difference is that feature-arm-vfp.inc is included in arch-armv5.inc while feature-arm-neon.inc only in armv7*.inc, so these options should be added to TUNEVALID also only for armv7* MACHINEs. * support vfpv4 with or without neon when both vfpv4 and neon are in TUNE_FEATURES we want to set only one -mfpu parameter and to neon-vfpv4 * prevent multiple appends to ARMPKGSFX_FPU, we don't want to include e.g. -vfp as well as -vfpv4 when both "vfp" and "vfpv4" are in TUNE_FEATURES * add -mfpu=vfp for tunes with "vfp" in TUNE_FEATURES - before that we were only adding -vfp to ARMPKGSFX_FPU * add TUNE_CCARGS_MFPU variable which is used to set -mfpu parameter as well as ARMPKGSFX_FPU suffix in TUNE_PKGARCH, all enabled values are appended to it based on TUNE_FEATURES and then the last one is used in the actual param and suffix * this prevents multiple -mfpu options in TUNE_CCARGS * !!! This means we need to change TUNE_PKGARCH and PACKAGE_EXTRA_ARCHS for vfpv4, vfpv3d16, vfpv3 tunes, because the -vfp* isn't prependend multiple times.

2015-07-02tune-core2.inc: set X86ARCH32 to i686 (instead of i586)Andre McCurdy
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.
