Sure, but part of that is a function of people doing coverage working on it and generally setting standards. > Plus you have to band-aid various trivia, like > - NR_IRQS being zero, > - No CPU or platform code included, causing link errors (e.g. head.o is > not built on m68k), > - ... That's not the case for all architectures, and TBH it seems like something that it's reasonable to fix at least in so far as it builds and links (assuming anyone wants to work on this for the architecutre). > Furthermore, allnoconfig disables CONFIG_MMU on architectures that support > nommu, which is less interesting, and thus need a KCONFIG_ALLCONFIG= > trick (I'd love to have just "make CONFIG_MMU=y allnoconfig" instead). That'd be nice, yes. Another thing that's interesting to me is getting the defconfigs up to the point where they run things like LTP well. --i8mz1utaBf8Zdcxn Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBAgAGBQJT7OYvAAoJELSic+t+oim9tAQP/0rx5LB2CsHs6mYRGT5VxtjC JSFogMXG0+jEEfRJ8bKMzcetTMaJGR6V+trIB5cPJJU5+EqbbvsP4MLrAWHvDyUA FGFF9mZkUZryxNVSJLy2nqD4HtuX/zH+UQ6IgqXxvBdtkN65WxK4MN5TIp0wsjeX 1HwiBCYTGhSaftCanDI31x8/emMx500OGB4C9CNp6K6XIE9SpptMgrwvt1rVvWli 0KGapMKCcDEXVaBPgaSp9Y7VYfl0u7hYGZDET1MoUHzifzASewJIFIdn/8vK7g1J p6NvVzn+CI1+N5cLsxgLZMRC6+T9FP2hrA3hIPt3E4Jqv4kdIfyBwTcezvt1SHUU ziDLh03WqIjeiYiSO8Ukjnlp1WbcRBRgcfyP0M+xQTDuNK0yHKHPhSUatgBDprll uzNTK9ALg9FLBtjTXK4tdvy04DuwiwDFajQpguD0c/dolD1YhQqWYjZN6ksS0ipR YNcsdwGyF03x20/EiO8jH2oNZq94oWETmdlHjXzpOYLdLt2KEyam8Mh/anGIShjF nMeSLC6SC3RD1KX3c82N3zCeNpaBr/eb4YnD1MfQInCrdhocGlVYQb6WfgDTF1uO GmqBGWyXtWpA95XYGiMqmW7A0Apvb1vWlJHu4AA9JARta+mkLKqznj5UKSJkkFg/ oVkbcAKO8r+IGVu+LekC =tNpn -----END PGP SIGNATURE----- --i8mz1utaBf8Zdcxn--
