amdgpu: don't ask about CHASH just default it for now. 2017-09-28T20:03:23+00:00 Dave Airlie airlied@redhat.com 2017-09-27T22:37:34+00:00 fdd495c57b87078dbcbbc07fa6bf93b5605a95ff If we bump this up a level, we can ask about it, for now, just default to what amdgpu does.

drm/amd: Closed hash table with low overhead (v2) 2017-09-26T18:53:19+00:00 Felix Kuehling Felix.Kuehling@amd.com 2017-08-24T23:22:32+00:00 5d86b2c391965cbcb295e8fa795276977b2a416e This adds a statically sized closed hash table implementation with low memory and CPU overhead. The API is inspired by kfifo. Storing, retrieving and deleting data does not involve any dynamic memory management, which makes it ideal for use in interrupt context. Static memory usage per entry comprises a 32 or 64 bit hash key, two bits for occupancy tracking and the value size stored in the table. No list heads or pointers are needed. Therefore this data structure should be quite cache-friendly, too. It uses linear probing and lazy deletion. During lookups free space is reclaimed and entries relocated to speed up future lookups. v2: squash in do_div and _BITOPS_LONG_SHIFT fixes Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
