Hello,
I'm new to kvm and I'm trying to log pci config and mmio read/writes for
a particular pci (pci-e to be precise) device that I've passthrough to
qemu-kvm (dma=none).
I put a printk into kvm_iodevice_read/write() in linux/virt/kvm/iodev.h
but the log seems to get corrupted when the action picks up.
I looked at qemu-kvm/hw/pci_host.c and found
pci_host_data_write/read_mmio[]. But I don't know where those are
implemented, nor exactly what they do for that matter.
I appologise for the n00b nature of my problem, but there isnt any
documentation on the pci-passthrough architecture in
linux/Documentation/kvm or in qemu-kvm.
Does anyone know where/how to log pci-passthrough accesses?
thanks,
Vik.
