[Mesa-dev] [PATCH 0/3] r600g/compute: Implement grow+defrag for compute_memory_pool

[Bruno Jiménez]

Hi,

This series is a follow up for the 'Adding support for defragmenting
compute_memory_pool' series. It also sits on top of the patch I sent
here: http://lists.freedesktop.org/archives/mesa-dev/2014-July/062923.html

It modifies the function 'compute_memory_grow_pool' so it can defrag
the pool at the same time as it grows it, thus reducing the total amount
of copies to one per item in the case grow+defrag. In the case where
the pool needs to grow, but it's not fragmented, then we copy only
the 'real' data that the items have, instead of copying the whole
resource, data and garbage at the same time.

The fallback path for grow+defrag isn't very good, but hopefully
it won't be used much.

As usual, if you have any doubt about any of the patches, just ask.

Thanks in advance!
Bruno
