I wanted to collect some thoughts on dropping agp_gart.
intel_express is still lugging around agp_gart for modern chipsets.
Classic Intel AGP chipsets exist as PCI devices with an extra
layer to speed up transfers. Without agp_gart the bus simply operates
at the slower pci speeds.[1]
We've been carrying around agp_gart a bit longer than we should of
as intel_extreme performs all of its gtt work through agp_gart.
Since us leveraging 3d hardware rendering on classic Intel AGP
chipsets doesn't seem likely, i'd personally like to see agp_gart
disappear as it layers on lots of added complexity.
If I were to rip out agp_gart (and still have a functional
intel_extreme driver) would anyone care?
