First of all, an internal fork was an unintended consequence. But since we are discussing this in a public forum, I won't go into more details. :) Creating yet another layer is certainly an option. For mainline purposes (a) is definitely a better choice. And I assume that would be public... On the other hand, if you only need this for couple of recipes, you can do this with alternative providers. E.g. instead of altering existing recipes with bbappends (e.g. cryptodev), you can have many providers for the same package (e.g. linux-ti-staging, linux-ti-mainline, even linux-yocto from OE-core all provide the Linux kernel, or virtual/kernel; same with u-boot from OE-core and u-boot-ti-staging plus u-boot-ti-mainline provide U-boot bootloader, like virtual/bootloaader). Those can be switched with a global PREFERRED_PROVIDER_<pkg> variable: https://git.yoctoproject.org/cgit/cgit.cgi/meta-ti/tree/conf/machine/include/k3.inc#n13 In other words, if cryptodev is the only such case right now, it's less involved to create cryptodev-ti-mainline recipes, set those to corresponding PROVIDES, as well as PREFERRED_PROVIDER_ in necessary config files. Let me know if you need help with that. > Any thoughts? > > -- > Regards, > Nishanth Menon > Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 > 849D 1736 249D > -- Regards, Denys Dmytriyenko <de...@denix.org> PGP: 0x420902729A92C964 - https://denix.org/0x420902729A92C964 Fingerprint: 25FC E4A5 8A72 2F69 1186 6D76 4209 0272 9A92 C964 _______________________________________________ meta-arago mailing list meta-arago@arago-project.org http://arago-project.org/cgi-bin/mailman/listinfo/meta-arago
