I still think it's preferable to change some drivers than everybody.
AFAIK BusLogic as real hardware is pretty much dead anyways,
so you're probably the only primary user of it anyways.
Go wild on it!
I don't believe anyone is materially maintaining the buslogic driver and
in time its going to break completely.
I think I was actually the last person to touch it ;)
Well that might be. I just think it would be a mistake
to design paravirt_ops based on someone's short term release engineering
considerations.
Agreed, especially as an interface where each in or out traps into the
hypervisor is broken even for the model of virtualising hardware.
Well, it's not necessarily broken, it's just a different model. At some
point the cost of maintaining a whole suite of virtual drivers becomes
greater than leveraging a bunch of legacy drivers. If you can eliminate
most of the performance cost of that by changing something at a layer
below (port I/O), it is a win even if it is not a perfect solution.
But I think I've lost the argument anyways; it doesn't seem to be for
the greater good of Linux, and there are alternatives we can take.
Unfortunately for me, they require a lot more work.
