drm/radeon: Use direct mapping for fast fb access on RS690

2013-04-09T14:31:31Z

This patch allows the CPU to map the stolen vram segment directly rather than going through the PCI BAR. This significantly improves performance for certain workloads with a properly patched ddx. Use radeon.fastfb=1 to enable it (disabled by default). Currently only supported on RS690, but support for RS780/880 and newer APUs may be added eventually.

drm/radeon/kms: display watermark updates (v2)

2010-03-31T04:54:47Z

- Add module option to force the display priority 0 = auto, 1 = normal, 2 = high - Default to high on r3xx/r4xx/rv515 chips Fixes flickering problems during heavy acceleration due to underflow to the display controllers - Fill in minimal support for RS600 v2 - update display priority when bandwidth is updated so the user can change the parameter at runtime and it will take affect on the next modeset.
