2) Add support for uncached GTT. I think it should improve performance for dGPUs under memory pressure, but some testing needs to be done to confirm that. Uncached GTT doesn't seem to work for me on Evergreen, but it's said to be working on some later chips.
FWIW, I think the issue is more likely with the code or your system than with the GPU: fglrx has always been using unsnooped GPU mappings with write-combined CPU mappings with PCIe as well. I'm not sure how they choose that vs. snooped and cacheable mappings though.
