Re: [Xen-devel] [v7][PATCH 06/16] hvmloader/pci: skip reserved ranges

Note here I don't address your comments above since I think we should achieve an agreement firstly.

I think bitmap mechanism is a good idea but honestly, its not easy to
cover all requirements here. And just like bootmem on Linux side, so its
a little complicated to implement this entirely. So I prefer not to
introduce this way in current phase.

I'm afraid it's going to be hard to convince me of any approaches
further complicating the current mechanism instead of overhauling

I agree we'd better overhaul this since we already found something unreasonable here. But one or two weeks is really not enough to fix this with a bitmap framework, and although a bitmap can make mmio allocation better, but more complicated if we just want to allocate PCI mmio.

So could we do this next? I just feel if you'd like to pay more time help me refine our current solution, its relatively realistic to this case :) And then we can go into bitmap in details or work out a better solution in sufficient time slot.
