And I think it's not necessary for mpc8315e to use e300c3 options. Could we close this bug? 18138 2 bruce.ashfield 2012-01-13 06:43:25 +0000 I see the tune files in: meta-yocto/conf/machine/mpc8315e-rdb.conf and meta/conf/machine/include/tune-ppc603e.inc Although not required, as a reference board it would be better to show the best possible tuning is used for a board. It should be as simple as pulling in the e300c3 tuning from open embedded, putting it in the oe-core machine/include directory and then changing the meta-yocto include for the mpc8315e-rdb to pick it up. A build and boot should be sufficient after that. 18174 3 liming.wang 2012-01-17 01:29:54 +0000 (In reply to comment #2) > I see the tune files in: > > meta-yocto/conf/machine/mpc8315e-rdb.conf > > and > > meta/conf/machine/include/tune-ppc603e.inc > > Although not required, as a reference board it would be better to show the > best possible tuning is used for a board. > > It should be as simple as pulling in the e300c3 tuning from open embedded, I didn't find the tune files of e300c3 in open embedded. 18180 4 bruce.ashfield 2012-01-17 07:24:05 +0000 Should be this: http://cgit.openembedded.org/openembedded/tree/conf/machine/include/tune-ppce300c3.inc and this board could be a reference: http://cgit.openembedded.org/openembedded/tree/conf/machine/mpc8315e-rdb.conf 18201 5 liming.wang 2012-01-18 01:49:09 +0000 (In reply to comment #4) > Should be this: > > > http://cgit.openembedded.org/openembedded/tree/conf/machine/include/tune-ppce300c3.inc > > and this board could be a reference: > > http://cgit.openembedded.org/openembedded/tree/conf/machine/mpc8315e-rdb.conf I copied a file tune-ppce300c3.inc from the tune-ppce300c2.inc in poky, and replaced 300c2 with 300c3 : --------------------------------------------------------------------- DEFAULTTUNE ?= "ppce300c3" require conf/machine/include/powerpc/arch-powerpc.inc TUNEVALID[ppce300c3] = "Enable ppce300c3 specific processor optimizations" TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "ppce300c3", "-mcpu=e300c3", "", d)}" TUNE_PKGARCH = "${@bb.utils.contains("TUNE_FEATURES", "ppce300c3", "ppce300c3", "${PPCPKGARCH}", d)}" AVAILTUNES += "ppce300c3" TUNE_FEATURES_tune-ppce300c3 = "m32 fpu-soft ppce300c3" PACKAGE_EXTRA_ARCHS_tune-ppce300c3 = "${PACKAGE_EXTRA_ARCHS_tune-powerpc-nf} ppce300c3" --------------------------------------------------------------------- I built the kernel, it can boot on the target successfully.

We can take more time on this, it is a more minor change, and if we had errors, I would have expected them on some of the graphics/mathematical userspace apps that have inline asm or other lower level assumptions. Good progress, keep working on this in the background, and now we have a better scope / understanding of the effort. 24895 7 bruce.ashfield 2012-09-06 18:31:22 +0000 I'll take this bug. 24897 8 bruce.ashfield 2012-09-06 19:26:26 +0000 patches submitted to the mailing lists 24924 9 bruce.ashfield 2012-09-07 12:30:00 +0000 Patches have been merged to master: a32f551c968dee86a801d8421e19ed7da92e6ac9 (meta-yocto-bsp) 72dc770cd926988b045cfff92ab30c89d6a417c1 (meta) 25958 10 yi.zhao 2012-09-29 08:31:25 +0000 Verified. git info: 718eb85806e080d0b165344b272e531ef19421eb git branch: poky/1.3_M5
