Hi Ard, I notice that you had ever worked on VirtNorFlashDxe, and maybe can help me on the following trouble.
I am trying to boot kvm VM on aarch64(arm-v8) with preempt-rt kernel host, the UpdateVariable is very very slow, and the uefi boot take about ~80s to get to phase, while it takes only about ~15s on a normal linux kernel or on x86 hardware. This only happen when the VM is first defined, or redefine the VM: virsh destroy VM; virsh undefine VM --nvram virsh define VM.xml ; virsh start VM It seems the most time spending when VirtNorFlash write operation at MmioWrite32(); On X64 platform，it seems use EmuVariableFvbRuntimeDxe driver，not really write the NorFlash device， Is it possible for arm to use the similar way as X64 ? Could you give any suggestion? Best Regards. Limin Wang -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
