All-

Anyone know how well Illumos handles modern Intel CPUs with different
types of cores (performance cores, aka P-cores, and efficiency cores,
aka E-cores)?

I'm specifically looking at Core Ultra 7 265K, which is/was "Arrow Lake"
I think, and has 8 P-cores and 12 E-cores.

If anyone is using current OI on a recent Intel with varying types of
cores, I would be interested to hear how it's working.

Thanks!

Tim
