Allocate ioat->ring memory from the device domain. Schedule ioat->poll_timer to the first CPU of the device domain. According to pcm-numa tool from intel-pcm port, this reduces number of remote DRAM accesses while copying data by 75%. And unless it is a noise, I've noticed some speed improvement when copying data to other domain. MFC after: 1 week Sponsored by: iXsystems, Inc. |
