[PATCH libdrm 3/5] intel: get a cached bucket by size

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Xiong, James" <james.xiong@xxxxxxxxx>

cached buckets are sorted by size in increasing order, each now
contains cached buffers with different sizes. A buffer with size
>= buckets[n].size and < buckets[n+1].size is put in bucket n
for future reuse.
