This is permanent issue for recording the cost of mode switch from different model. It's welcome to append your result in this chain.

EDIT: Before fennecJ 's post (including), the result are done on x86_64 and needed multiply 0.83 because bug fixing in b939863. Also, due to #7 , aarch64 was supported.

  • Intel Core i5-7300HQ

(Mitigations ON):

Model name: Intel(R) Core(TM) i5-7300HQ CPU @ 2.50GHz
Vulnerability Meltdown: Mitigation; PTI

Avg of mode switch takes 656.33 cycles and standard deviation is 18.44

(Mitigations OFF):

Model name: Intel(R) Core(TM) i5-7300HQ CPU @ 2.50GHz
Vulnerability Meltdown: Vulnerable

Avg of mode switch takes 190.26 cycles and standard deviation is 20.20

(I'm quite curious about why my time in cycles with mitigations enabled was so below average (656 vs ~1405 cycles), does anyone have any ideas? maybe the kernel version?)
