[PATCH 2/3] dma-bikeshed-fence: Hardware dma-buf implementation of fencing

2012-08-07 Thread Maarten Lankhorst
This type of fence can be used with hardware synchronization for simple hardware that can block execution until the condition dma_buf[offset] >= value has been met, accounting for wraparound. A software fallback still has to be provided in case the fence is used with a device that doesn't support
