So it seems to me that a better fix would be to change the freq_desc_byt struct from: static const struct freq_desc freq_desc_byt = { 1, { 83300, 100000, 133300, 116700, 80000, 0, 0, 0 } }; to: static const struct freq_desc freq_desc_byt = { 1, { 83333, 100000, 133300, 116700, 80000, 0, 0, 0 } }; That should give us the right TSC frequency without needing to mess with the TSC_KNOWN_FREQ and TSC_RELIABLE flags.Where does that number come from? Just math?
Yes just math, but perhaps the Intel folks can see if they can find some datasheet to back this up ? I mean if the calculated freq is off by that much, then chances are that my solution actuallly is not only "just math" but also correct :) Regards, Hans
