Hi,
This patch series adds a qdev flag which allows devices being tagged as
not hotpluggable. It also sets this flag for a number of devices.
Do we want to be able to mark device as not hot-unpluggable from command
like too? Something like this -device blabla,notunplug=no.
Hmm, dunno. Do you have a example where this would be needed or useful?
Dunno me too. Windows allows to eject any hot-unpluggable device to any
user and in the past we got requirement to disable this and had to build
two BIOSes one with cpu hot-plug support another without. So
hot-pluggability of device looks like management decision (along with
technical one if device can't be actually unplugged).
For *that* use case well have to do a bit more like dynamically building
the acpi table which indicates which slots are hot-pluggable and which
are not. Which indeed would be useful and would fix the windows xp
offering me to unplug the piix chipset in the "savely remove hardware"
menu ;)
But I suspect it also isn't exactly trivial and way behind the scope of
this little patch set ...
cheers,
Gerd
