Subject: | [Qemu-devel] QEMU tries to register to VFIO memory that is not RAM |
Date: | Fri, 31 May 2019 13:32:29 +0000 |
When configuring device pass-through via VFIO to a VM, I noticed that QEMU tries to register (DMA_MAP) all memory regions of a guest (not only RAM). That includes firmware regions like "pc.rom". Would a physical device ever need access to those? Am I missing something?
