[Xen-devel] Bug: Limitation of <=2GB RAM in domU persists with 4.3.0

[Gordan Bobic <gordan@xxxxxxxxxx>]

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU 
passthrough without crashes. Unfortunately, the same crashes still 
happen. Massive frame buffer corruption on domU before it locks up 
solid. It seems the PCI memory stomp is still happening.
I am using qemu-dm, as I did on Xen 4.2.x.

So whatever fix for this went into 4.3.0 didn't fix it for me.
Passing less than 2GB of RAM to domU till works fine.

I have attached:

qemu-dm log for domU
xl dmesg
