exa: implement TegraEXAMarkSync / TegraEXAWaitMarker #21

Closed digetx closed 7 years ago

Potentially this should yield a better Xorg performance. The tegra_stream has been extended with an async submission and fence get / put helpers, get returns fence for the latest submitted job and put waits for a job completion, freeing fence in the end.

Depends on https://github.com/grate-driver/libdrm/pull/13

Well, but I still don't think grate-driver/libdrm#13 is the right move.

I'll re-open this PR once we'd have all required kernel and libdrm bits landed.
