[Mesa-dev] [RFC PATCH 00/14] Do not use userptr in anv if softpin is available.

[Rafael Antognolli]

This series changes anv_block_pool to use a list of BO's instead of a
single BO that gets reallocated and set with userptr.

The main changes are:
   - The introduction of anv_state_table to track anv_states, and
   recycle them;
   - Addition of a list of BOs in anv_block_pool, instead of a single
   BO;
   - Forcing allocations to not cross boundaries between the previous
   size of a block_pool and the new one;
   - And pushing back the "padding" required to avoid such boundaries
   cross to the pool of free anv_states.

I'm still working on increasing the test coverage (adding new tests for
some new cases we have now), but the series seems reasonable imho to
start getting some review already.
