Hello All, It is not a secret that all open source emulators
(QEMU, Bochs, Xen) use the same emulated devices and mostly copy-paste their
emulation one from another. I don’t know who originally wrote the device models
but now Bochs and QEMU maintain two similar implementations of the same
devices. If one of the teams fixes the implementation or add
functionality, another team mostly copy-paste the changes to their model. Xen project forked from QEMU and want to stay in
touch with Bochs and QEMU device models and contribute the changes to make the
model better. I am wondering about making unified device models
architecture for open source simulators. The device models will be used in QEMU, Bochs, Xen
and other open source simulators which would use the device models. I know about two professional teams working in
simulation which would like to use these device models in their simulator and could enrich the device library with new devices
device interfaces, for example with AGP and 3D graphics. Bochs is already in middle of definition of new true
pluginable devices architecture. In near future Bochs devices will fully separatable
from Bochs binary and when could be developed separately from Bochs. I call to QEMU developers join to this project and
come with their requirements to plugin architecture. I don’t know if QEMU supports device plugins
now but I would like to see QEMU a part of this idea, I would like to get single device shared library
which could be loaded to Bochs and QEMU and work perfectly for both. This will eliminate the need to maintain two separate
implementations of the same devices, these implementations very fast will converge to
single one, C or C++ based, Bochs or QEMU based, doesn’t matter. I am listening for your opinions ! Thanks, Stanislav |
