Hi Hong, Thank you for the patch and sending it to this list. -----Original Message----- > Hi Crash > > I'll keep refining the patch before it get approved: OK, so we will wait for the refined patch. Thanks, Kazu > > > 1. Fix the error in arm64_overflow_stack_init() which saved the overflow stack address into > ms->irqstacks[], which would cause bt command crash on other cpus. The normal IRQ stacks should be used > for bt command for other cpus. > 2. In addition to unwind on the overflow stack, try to go through the IRQ stack to find more useful > information > > Kernel stack overflow case would be rarely but I'd like to sharp the crash to cover this kind of issue. > > Best regards > Hong > ________________________________ > > From: Hong Yang3 杨红 > Sent: Tuesday, November 16, 2021 9:55 > To: crash-utility@xxxxxxxxxx <crash-utility@xxxxxxxxxx> > Subject: arm64: Support overflow stack panic > > Hi All > > When I was trying to open a core of an overflow stack panic result, the bt command caused a segment fault, > after a while I figured out the overflow stack is not supported by crash utility. > > This patch is trying to initialize the overflow stack information on startup stage, and the bt command works > as expected to dump the correct call trace in the overflow stack, currently it only apply to arm64 target. > > I'm not sure if any other sub command also need to be fixed for full support for the overflow stack, please > advise and I'll try to improve the patch. > > Thanks > Hong YANG -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/crash-utility
