Hello, This series converts drm/cirrus to support atomic modesetting for the emulated CL GD-54xx hw in qemu. Patches 1-7 are general fixes and improvements, in preparation for atomic. Patch 8 provides dmabuf export for cirrus. Patch 9-11 add universal primary plane support and rework the driver to use atomic transition helpers for legacy modesetting. Patch 12 moves away from legacy modesetting entirely to use atomic handlers. Patch 13 adds atomic cursor plane. Patch 14 flips on DRIVER_ATOMIC. I have tested this with igt and chromeos/drm-tests (details in patch 14). Fun trivia from the GD-54xx TRM, 1996! It boasts 'optimized PCI burst write, which supports PCI writes to the frame buffer at greater than 55 Mbytes per second.'
