Greg, I recently discovered that the Hyper-V host allocates mmio memory for some synthetic devices like the virtual framebuffer. We are currently in the process of implementing this virtual framebuffer device. As part of the offer message from the host we are given the mmio region size that needs to be allocatted to the device. I am told in the current implementation of the firmware, this mmio resource shows up in the PCI space. What is the best way to allocate this mmio space for this driver. Regards, K.
