Hi guys, Well let's face it AGP is a total headache to maintain and dead for at least 10+ years. We have a lot of x86 specific stuff in the architecture independent graphics memory management to get the caching right, abusing the DMA API on multiple occasions, need to distinct between AGP and driver specific page tables etc etc... So the idea here is to just go ahead and remove the support

Unfortunately AGP is still to widely used as we could just drop support for using its GART. Not using the AGP GART also doesn't mean a loss in functionality since drivers will just fallback to the driver specific PCI GART. For now just deprecate the code and don't enable the AGP GART in TTM even when general AGP support is available. Please comment, Christian.
