Sure, will do both. > 1) What is the device list of microvm? It is a minimal virtual machine designed for modern (aka virtio-aware) guests. Most legacy isa devices (pic, pit, rtc) are optional and can be turned off. storage/network/etc. uses virtio-mmio. Optional pcie support is available and any pcie device supported by qemu cane plugged in (including virtio-pci if you prefer that over virtio-mmio). > Or do you mean https://qemu.readthedocs.io/en/latest/system/i386/microvm.html? Yes, it's this. > 2) How many QEMU configurations do we want to support? This series adds just the basics. I want add support for virtio-mmio and pcie later on, once the basics are sorted and merged. > 3) What is the reason to add a new dsc/fdf instead of add a MACRO/PCD in OVMF? microvm borrowed a bunch of ideas from arm virt. So it doesn't work like a classic pc chipset in many areas. There is no pci config space access via ioport 0xcf8 for example. Also power management works completely different (see patch #14). Adapting at runtime would need glue code basically switching between between different *Lib implementations, depending on machine type. Similar to DxePciLibI440FxQ35 for pci / pcie, but for a bunch of more places too. Xen moved to a separate dsc/fdf too recently, I suspect for simliar reasons. take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
