powerpc-tunes: Introduce bigendian tune

2019-09-03T08:55:50+00:00

This helps in defining LE tunes and at the same time specifies endianness on compiler cmdline clearly, clang e.g. defaults to little-endian always, so unless specified with -mbig-endian won't compile the code right (From OE-Core rev: e0fd699d398f0e88fb208970dea7b74e6e9431fe) Signed-off-by: Khem Raj Signed-off-by: Richard Purdie

tune-ppce500mc.inc: pass -mcpu=e500mc for ppce500mc kernel compile

2016-07-10T13:12:17+00:00

Currently the -mcpu parameter is not passed to cross gcc when assembling kernel .S file, the implicit -mcpu option that defaults to the latest server cpu might casuse incorrect assembling. A existent case is that wait instruction of ppce500mc is incorrectly assembled to power9 version with default -mcpu setting, accordingly kernel boot calltrace happend when wait instruction is executed on ppce500mc targets.

conf/machine: use .= instead of += in TUNE_CCARGS

2013-04-29T13:45:06+00:00

* number of TUNE_CCARGS conditionals is important if we add extra space with each one in "else" branch I'm building for 2 MACHINEs one is cortexa9, second is cortexa8 few months ago we added TUNE_CCARGS[vardepvalue] in bitbake.conf http://git.openembedded.org/openembedded-core/commit/?id=03f1e34ea3ce80931e9c3cd2ab22824f28a7233b which fixed some cases (like mentioned tune-xscale and tune-arm926ejs) where both had unused TUNE_CCARGS when common DEFAULTTUNE was used. with cortexa[89] it's different, because cortexa9 has one extra TUNE_CCARGS TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "cortexa9", "-mtune=cortex-a9", "", d)}" which adds extra *space* even when not used because of '+=' and as result: $ bitbake-diffsigs tmp-eglibc/sstate-diff/1366797730/*/armv7*/adapterbase/*do_configure* basehash changed from f986789fb8fb3579ed6a3492cc8a8d10 to c851b5f838d945ee13072e9ad6725dca Variable TUNE_CCARGS value changed from ' -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mfpu=neon ' to ' -march=armv7-a -mthumb-interwork -mfloat-abi=softfp -mfpu=neon ' Hash for dependent task gcc-runtime_4.7.bb.do_populate_sysroot changed from bdeabf7a86958b9110b566344b7916de to 2be5618e6bc8c57ec9db5659bf217915 Hash for dependent task eglibc_2.17.bb.do_populate_sysroot changed from b4f40fc62dde684acd0a574532a55360 to 97fcb426603d4a1c1099c0504d2ebf7d Hash for dependent task glib-2.0_2.34.3.bb.do_populate_sysroot changed from fd2f90b83098c34e88d649d70f6ea4f5 to ebd740bb94ea3eb0a914efda6fc82c4a (From OE-Core rev: b7430ff83760ac29079d20dc7c62f498a0a9d55d) Signed-off-by: Martin Jansa Signed-off-by: Saul Wold Signed-off-by: Richard Purdie

conf/machine/include: Cleanup PowerPC tunings to match README

2012-04-04T16:17:55+00:00

Cleanup the PowerPC tunings to match the new tuning README file. Default PowerPC to using TUNE_PKGARCH = ${TUNE_PKGARCH_tune-} Fix AVAILTUNE settings in ppc603e, and ppce500mc to be addative. Correct potentially overlapping "spe" definitions in ppce500 and ppce500v2. (From OE-Core rev: f81f71bcff4bb1032b034b068efe6065113ca9e7) Signed-off-by: Mark Hatle Signed-off-by: Richard Purdie

tune-ppc: Update to pass glibc configure option to get cpu specific support

2011-08-12T16:21:57+00:00

We need --with-cpu based to glibc to get proper support on 603e & e500mc to pickup proper math libs to deal with sqrt. These core do not implement the fsqrt[s] instructions that the normal PPC math libs utilize. This causes use to not set AVAILTUNES specifically to the sub-arch only as we arent generically compatiable.

tune/ppc: Fix various TUNE_PKGARCH issues

2011-08-02T13:41:03+00:00

We need to ensure only one value ends up in TUNE_PKGARCH rather than several. This change ensures consistency accross all the PPC tune files and that they correctly inherit the core value but also allow it to be overwritten.
