Hi Gerd:
Thanks for your reply. In fact, I have no choice, only QXL in my work.
1. I wonder why the device display be normal when it hung on bus=pci.8,addr=0x0, but it is abnormal when bus=pci.9,addr=0x1 or bus=pci.7,addr=0x0.
2. Why cache properties are going to cause QXL display abnormal on ARM. Are there any links or materials? Thanks.
take care
Lange
