DMA-BUF Cross-Device Synchronization Hits Linux 3.17

[gilboa]

It will be usable by all the drivers using prime. NVIDIA's driver included.

Was DMA-BUF symbols GPL only?
... Goes to check.
Yep: All the symbols I see are still EXPORT_SYMBOL_GPL making them invisible to any proprietary drivers.

Nvidia uses a shim to access dma-buf.

PRIME offloading works just fine with the proprietary driver.

Any update on the userspace drivers? Playing with PRIME is still not an option for any halfway serious gamer. Just look at this: https://imgur.com/a/z042B
It's far too jarring and distracting having this stuff and the images don't even show the flickering of old frames that's happening all the time. If your brain picks up the wrong frames it's practically impossible to aim properly.
