Hi Lianbo, Tao
Let gdb fetch_registers include cpu context x19~x28,
This may not mean for already scheduled tasks, but
gdb stack unwind show more args.
Before:
crash> gdb bt
#0 __switch_to (prev=<unavailable>, prev@entry=0xffffff80025f0000,
next=next@entry=<unavailable>) at arch/arm64/kernel/process.c:566
#1 0xffffffc008f820b8 in context_switch (rq=0xffffff81fcf419c0,
prev=0xffffff80025f0000, next=<unavailable>, rf=<optimized out>) at
kernel/sched/core.c:5471
#2 __schedule (sched_mode=<optimized out>, sched_mode@entry=168999904)
at kernel/sched/core.c:6857
#3 0xffffffc008f82514 in schedule () at kernel/sched/core.c:6933
...
After:
crash> gdb bt

Hi, Guanyou
Thank you for the patch. I can not apply this one in my local git repo. Could you please double check?
$ git apply this.patch
error: corrupt patch at line 114
error: corrupt patch at line 114
BTW: I haven't looked at the code yet.
Thanks
