| +CONFIG_PROFILING=y | +CONFIG_OPROFILE=m Somehow we need to merge the oe config changes into the one we publish in git. The intention of the toplevel defconfig-gta01 and defconfig-gta02 files is that they are our packaging config. It'd be good if instead of forking it we had a single accurate config for GTA01 and GTA02 in the kernel tree. I wrote a patch to change these configs on 2.6.24 stable branch, but I can't test it right now and I wonder about one thing with profiling, on 2.6.27 I enabled FTRACE and it attached stuff to __attribute__ ((naked)) functions and killed FIQ thereby. Can you confirm it OK with whatever it is OPROFILE does for instrumenting functions? If so I'll add it in the kernel tree. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkj9E9wACgkQOjLpvpq7dMrtMwCeLz0claUBnF+zdEAkCnzxdJ7C ByQAoIsGGUuS56VybKoP4jNZ8FwYNI0L =Jp6h -----END PGP SIGNATURE----- _______________________________________________ devel mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/devel
