Vijay 7069532e3b target-arm: Use Neon for zero checking ... Use Neon instructions to perform zero checking of buffer. This is helps in reducing total migration time. Use case: Idle VM live migration with 4 VCPUS and 8GB ram running CentOS 7. Without Neon, the Total migration time is 3.5 Sec Migration status: completed total time: 3560 milliseconds downtime: 33 milliseconds setup: 5 milliseconds transferred ram: 297907 kbytes throughput: 685.76 mbps remaining ram: 0 kbytes total ram: 8519872 kbytes duplicate: 2062760 pages skipped: 0 pages normal: 69808 pages normal bytes: 279232 kbytes dirty sync count: 3 With Neon, the total migration time is 2.9 Sec Migration status: completed total time: 2960 milliseconds downtime: 65 milliseconds setup: 4 milliseconds transferred ram: 299869 kbytes throughput: 830.19 mbps remaining ram: 0 kbytes total ram: 8519872 kbytes duplicate: 2064313 pages skipped: 0 pages normal: 70294 pages normal bytes: 281176 kbytes dirty sync count: 3 Signed-off-by: Vijaya Kumar K <vijayak@cavium.com> Signed-off-by: Suresh <ksuresh@cavium.com> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: 1467190029-694-2-git-send-email-vijayak@cavium.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>		2016-07-14 16:51:36 +01:00
