'olddefconfig' just takes the platform or architecture defconfig and updates it for any new CONFIG_* variables added since the last time the defconfig was updated in the tree. yes "" | make oldconfig does the same updating for new CONFIG_* variables, but starts with the most recent .config - which produces wildly different results if the .config had previously been minimized by 'make localmodconfig' or other similar techniques. --==_Exmh_1567433334_4251P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBXW0idQdmEQWDXROgAQJuVQ//ZBKGZDGSTWRPKMW02OhRokN+dPP5/h4F 9+uV6+0ppyFqPnIJkqrz8llxiiZnRwdACWBe54puuo1EaclnGQiOrw5MPk00tHmU JWZS9ZGip+HLOeOT/BwF9D5cLpaH6q0hctZeAB0V91U/96+eAt7dXOVEnyaE+/ZY HL7p/oNV54GjEAXpKkobdqBGJue6lkt7LQm4I7/wMJpioySFgd0QLpUJ5bRRW1Mf jF/YRdVXaKuyd+2EE23FatkLmVzNRN6zmJvRY/uJthBTpYxxiBa21r01qchB4Vcb gZUABGQ14+H2dDYb/pAFwwqsko4No4R0YzPzqy+Gj0SHfNOEt+ORbdYDN2HxSMwK 6YdoezaDS/OZbljJNWNzL3CMHw+tF/etXjauLqC0gszekc/kaAOsaKWGnF4eIcP8 3on7Y7TgUC676YiQahLVVXx2V1Z5Hmg7Ne8VEn/9N3tBbUqJYuAjNJ2QjpkAX8X5 y9AmSOw4uIjbOgYSOnNynu+ladhGlaI7IaqVWowuIkPH/e3Ygc/qykBSnB1hvWUW 4kDRBozljP/q/2Rm4BC3A9UYKnjKCW6/QggGlZQdhJTwhMNNS9lHWEu/uDZsrm07 92ZoXRI8KDJui7cYpRWYmZO1ttir9zwBKxzqYNIqaciG3ZkAUKdOI3CWqxFImeEd PyWXaxihe0o= =1WgW -----END PGP SIGNATURE----- --==_Exmh_1567433334_4251P-- --===============9069516475914618010== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies --===============9069516475914618010==--
