Re: Ask for help,about cpu down after jailhouse enable。。
Thanks for your reply! Before jailhouse enable, the CPU can be powered on and off normally. But after that, offline cpu(echo 0 > /sys/devices/system/cpu/cpu3/online) causes panic, even without jailhouse create. 在2022年8月11日星期四 UTC+8 19:34:32 写道: > Am Wed, 10 Aug 2022 23:29:16 -0700 (PDT) > schrieb star sun : > > > i want make jailhouse working in one phone with 4 cortex-a53 cpu. > > > > I feel like I've successfully executed jailhouse enbale. > > unfortunately, there is a kernel panic when i down one cpu for a > > non-root-cell during jialhouse cell create . > > > > This question has puzzled me for a long time Do you have any good > > methods? thank you > > You could try offlining one or more CPUs with your stock kernel and not > even the jailhouse module loaded.

If that also causes problems you are likely dealing with a vendor kernel that has been patched to become sort of broken. echo 0 > /sys/devices/system/cpu/cpu3/online writing a 1 will bring it back. This should work before you even start with jailhouse. Henning -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
