Hi, I have been trying to add a new scheduler to the Linux kernel. I have found that to add a sched_class, I need to add it to SCHED_DATA in vmlinux.lds.h. instead of editing the now removed .next variable. Depending on what order I put into the priority list, it will crash the kernel during the booting process after rebooting. Any tips on what could be causing this would be appreciated! Currently this works #define SCHED_DATA \ STRUCT_ALIGN(); \ __begin_sched_classes = .; \ *(__idle_sched_class) \ *(__my_sched_class) \ *(__fair_sched_class) \ *(__rt_sched_class) \ *(__dl_sched_class) \ *(__stop_sched_class) \ __end_sched_classes = .; While this does not #define SCHED_DATA \ STRUCT_ALIGN(); \ __begin_sched_classes = .; \ *(__idle_sched_class) \ *(__fair_sched_class) \ *(__my_sched_class) \ *(__rt_sched_class) \ *(__dl_sched_class) \ *(__stop_sched_class) \ __end_sched_classes = .; Regards Jacob
