Hi,
Next version of the virtio-gpu driver. Turned into a little patch series now. Most review comments should be addressed.
Changes in v2: * add support for universal plane * add support for atomic modesetting * make non-failing funcs return void, kill pointless error checking * allocate vbuffers at init time, to avoid allocations in critical paths * license clarification (dual mit/gpl) * splitted vga handling into separate patch * improve error handling * codestyle fixes * misc minor tweaks here and there
Still on the todo list: * sort how to handle vga compatibility best, for now the bits just have been splitted into a separate patch so they are easier to spot and don't confuse when reviewing the main parts of the driver. * properly handle page flip.
cheers, Gerd
