Hi,
Okay, my vote is 0x8000_0000 (2GB) then.
I will modify the patch as follows: simultaneously with programming the
exbar at 2GB, I will lower the start of the 32-bit PCI aperture from the
current 3GB (0xC000_0000) to (2GB+256MB == 0x9000_0000). Is that alright?
Yes, that should work fine.
FWIW that's how Intel physical servers I've dealt with are arranged:
2GB of low RAM followed by PCIe space and MMIO.
