Re: [Xen-devel] Setting up a call to discuss PCI Emulation - Future Direction

Hi all,
so it seems we have no perfect slot proposals, but 2 semi-perfect.
May 2nd: 16:00 - 17:00 Christopher can't attend
May 2nd: 17:00 - 18:00 Chao can't attend
Maybe a compromise would be 16:30 to 17:30

    1. different approaches to handle some critical chipset-specific
       registers (MCH PCIEXBAR first of all), currently emulated by
       QEMU. Role of QEMU in the emulation of MMCONFIG accesses.
    2. MMIO hole sizing in general (for HVM) -- in which PT usecases this is
       needed, requirements, limitations. It is related to the emulated
       chipset-specific resources and depends on the chosen solution for #1.
    I'll try to describe different possible implementations how to make the
    multiple PCI device emulators feature compatible with emulated MMCONFIG
    before the meeting, to have a ground for discussion. There are at least
    3 possible directions currently to solve this problem.
