Hi Fengguang/All, I am working as the OpenRISC linux kernel maintainer. Currently in linux-next our patches are causing kbuild test robot to fail.
This is because the patches are taking advantage of 2 'new' (2 year old) instrucions (l.swa/l.lwa) and the build robots, as far as I can tell, use the 'make.cross' [0] build script from lkp-tests.git. These point to the crosstools [1] toolchains maintained by Tony. I sent a mail to Tony who maintains the crosstools but I didn't get a reply and it seems he is not longer working on them [1]. I think our options are: 1. Update 'make.cross' to point somewhere else for openrisc 2. Update and maintain crosstools For 1. its trvial but, maybe not the best solution. For 2. I created new crosstool builds for openrisc [3]. The way the crosstools are maintained is via a patches.tar file and it seem a custom buildall script. I dont see the source for that custom script anywhere. I am thinking I could help to update and 'opensource' the crosstool build scripts to make it easier for everyone to update toolchains by sending patches. But, I would need access to crosstool on kernel.org and an OK from everyone. Any opinions? Questions? -Stafford [0] https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/tree/sbin/make.cross [1] https://www.kernel.org/pub/tools/crosstool/ [2] https://marc.info/?l=linux-kernel&m=146406282809809&w=1 [3] http://shorne.noip.me/crosstool/files/
