Brad Volkin 493018dcb1 drm/i915: Implement a framework for batch buffer pools ... This adds a small module for managing a pool of batch buffers. The only current use case is for the command parser, as described in the kerneldoc in the patch. The code is simple, but separating it out makes it easier to change the underlying algorithms and to extend to future use cases should they arise. The interface is simple: init to create an empty pool, fini to clean it up, get to obtain a new buffer. Note that all buffers are expected to be inactive before cleaning up the pool. Locking is currently based on the caller holding the struct_mutex. We already do that in the places where we will use the batch pool for the command parser. v2: - s/BUG_ON/WARN_ON/ for locking assertions - Remove the cap on pool size - Switch from alloc/free to init/fini v3: - Idiomatic looping structure in _fini - Correct handling of purged objects - Don't return a buffer that's too much larger than needed v4: - Rebased to latest -nightly v5: - Remove _put() function and clean up comments to match v6: - Move purged check inside the loop (danvet, from v4 1/7 feedback) v7: - Use single list instead of two. (Chris W) - s/active_list/cache_list - Squashed in debug patches (Chris W) drm/i915: Add a batch pool debugfs file It provides some useful information about the buffers in the global command parser batch pool. v2: rebase on global pool instead of per-ring pools v3: rebase drm/i915: Add batch pool details to i915_gem_objects debugfs To better account for the potentially large memory consumption of the batch pool. v8: - Keep cache in LRU order (danvet, from v6 1/5 feedback) Issue: VIZ-4719 Signed-off-by: Brad Volkin <bradley.d.volkin@intel.com> Reviewed-By: Jon Bloomfield <jon.bloomfield@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2014-12-16 10:39:08 +01:00
