Hello, this is my first time on a mailing list. I'm not sure how this works. The FAQ linked on this page: https://wiki.linuxfoundation.org/realtime/communication/mailinglists just says "Page not found". I hope I can just ask a question this way. I'm currently trying to automate the build of a Linux kernel with the RT PREEMPT patch. The kernel that I'm trying to build is in this git repository: https://github.com/raspberrypi/linux (branch rpi-4.14.y) It's the official kernel for the Raspberry Pi. But at the moment I am stuck. There are two problems. When I apply the patch "patch-4.14.15-rt13.patch.gz", I get errors like: Hunk #9 FAILED at 795. ... 1 out of 20 hunks FAILED -- saving rejects to file kernel/softirq.c.rej ... and as a result of this it exits with code 1. Here is the full build process output: https://gitlab.com/T-vK/rpi-rt-kernel/-/jobs/51343435 When I just ignore it and continue I get to the point where I can run "make zImage", which then fails with this: kernel/softirq.c: In function 'invoke_softirq': kernel/softirq.c:801:3: error: implicit declaration of function 'do_softirq_own_stack' [-Werror=implicit-function-declaration] do_softirq_own_stack(); ^ kernel/softirq.c:806:2: error: #else without #if #else /* PREEMPT_RT_FULL */ ^ kernel/softirq.c:807:2: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement] unsigned long flags; ^ kernel/softirq.c:817:2: error: #endif without #if #endif ^ cc1: some warnings being treated as errors scripts/Makefile.build:320: recipe for target 'kernel/softirq.o' failed make[1]: *** [kernel/softirq.o] Error 1 Makefile:1028: recipe for target 'kernel' failed make: *** [kernel] Error 2 The full log is in the build output linked above. I've been trying to follow this guide: http://www.frank-durr.de/?p=203 This is my "build script" if you will: https://gitlab.com/T-vK/rpi-rt-kernel/blob/master/.gitlab-ci.yml The docker image it runs on has been build from this file: https://gitlab.com/T-vK/rpi-rt-kernel/blob/master/Dockerfile I should mention, the patch that I apply right before "make zImage" (patch < rt-config.patch) simply applies this menuconfig setting: Kernel Features → Preemption Model (Fully Preemptible Kernel (RT)) → Fully Preemptible Kernel (RT) (I just created the default config for rpi-4.14.y using "make bcm2709_defconfig" and then copied it and modified the above mentioned option using "make menuconfig" and then I just ran a "diff -u ..." on it to create the patch) Can anyone help me with these issues?
