Hi,

Sorry for top posting, but this is a long and almost unreadable thread ...

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?

Thanks,
