Hello,
I am trying to boot kvm VM on aarch64 preempt-rt kernel host,
it is very very slow (~80s) for the first defined VM to boot until grub interface ,
while it's only takes about ~15s for the normal linux kernel (without FULL preemptable mode) or on x86 platform,
and it looks normally if the VM is not the first boot after defined.
The most time spend in the FvbWrite() with NorFlash operation.
Do you have any test on FULL preempt kernel ?
Best Regards.
Limin Wang
