Linux only detect 4 cores out of 8 when using this patch #2

Yes, everything still works, but with 4 cores instead of 8.

I have a Samsung Galaxy A6, which has exynos7870 SoC with 8 Cortex-A53 cores. But after applying this patch, Linux only detect 4 cores. The other 4 cores are always set as 0Mhz, or offline (output from CPU Info app, CPU-Z app and SmartPack Kernel Manager). Using htop output 4 cores, lscpu also output 4 cores.

I don't know if Knox (vmm.elf) has the responsibility for starting up these 4 cores?

Any ideas? Thanks!

Remove exynos hotplug driver completely. May solve the issue, but not sure.

Thanks! I will try it soon!

I think the issue is with the driver when you are building on ubuntu 20 or later

to disable the driver you can
add entry for hotplug driver alone in drivers/soc/samsung/Kconfig
and in drivers/soc/samsung/Makefile change obj-$(CONFIG_ARCH_EXYNOS) += exynos-cpu_hotplug.o
to obj-$(CONFIG_EXYNOS_CPU_HOTPLUG) += exynos-cpu_hotplug.o

also in drivers/base/core.c find exynos_cpu_hotplug_enabled() and the line before change #ifdef CONFIG_ARCH_EXYNOS to #ifdef CONFIG_EXYNOS_CPU_HOTPLUG

where CONFIG_EXYNOS_CPU_HOTPLUG is the new entry you created.

I build on Debian 11 :))
Thanks for the details

Add option to disable CPU hotplug
0d064ff 
When we use KVM, we actually threw away the RKP, which might be responsible for the CPU hotplug process. So Android will only detect 4/8 cores on the phone.
By disabling CPU hotplug, we force all cores to work

Thanks! All 8 cores worked for now!

NOTE: I have to disable all things releated to CPU hotplug in .config file, including CONFIG_EXYNOS_HOTPLUG_GOVERNOR. How to do this is up to you, you can comment out the code if you like :))
