Hi Dave,
A few more radeon patches for 3.18. This patch set gives us more
flexibility with respect to buffer placement in vram with respect
to CPU access. E.g., if you know you will not need CPU access, we can
now pin outside of the CPU window, reducing contention for the
CPU window space.
We also have an additional patch set from Christian to enable concurrent
buffer reads. It uses the new fence code to avoid unnecessary
serialization of command streams when a buffer is read by multiple
engines at the same time. It would be nice to get some additional
comments on it since it requires some minor changes to ttm. I've
sent you another email about it.
The following changes since commit fdcaa1dbb7c6ed419b10fb8cdb5001ab0a00538f:
