[Android-virt] [PATCH] Handle SCTLR & CPACR read/write in KVM ARM.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Realview-PB-A8 kernel boots fine on QEMU Emulator. The kernel gets
alignment faults only when we try to use KVM ARM. This does not mean there
is an issue with KVM ARM because I see similar behavior on Xvisor ARM too.

Although, I did not see this issue with VExpress-A9 kernel, so have
mentioned it explicitly in my patch. Making this change CPUID specific
would be even more correct way of doing it.
