Dear RT folks, I found an uncomprehended value of hackbench while I tested preempt rt patches on my ARM64(Cortex A76 x 8) target. So, I decided to check it on QEMU x86_64 KVM with yocto. I executed both images with below command. $ runqemu qemux86-64 kvm nographic qemuparams="-smp cores=4" I was able to get similar score values with my arm64 target. It was half than 5.10.75 kernel like below. Any idea about this? Actually, I'm not sure it could be a regression or not. <5.10.75-rt47> root@qemux86-64:~# hackbench -l 10000 Running in process mode with 10 groups using 40 file descriptors each (== 400 tasks) Each sender will pass 10000 messages of 100 bytes Time: 49.898 <5.14.14-rt21> root@qemux86-64:~# hackbench -l 10000 Running in process mode with 10 groups using 40 file descriptors each (== 400 tasks) Each sender will pass 10000 messages of 100 bytes Time: 96.973 Best Regards, Chanho Park
