I examined those among the machines I have, and got the results as: x86intel[] table in /sys/src/9/pc/devarch.c, like: x86intel[]= { ---- /* {6, 0x3A, 16, "Core i7"}, */ { 6, 0x3A, 16, "3rd Gen Core i-3/5/7", }, { 6, 0x3C, 16, "4th Gen Core i-5", }, { 6, 0x5E, 16, "6th Gen Core i-5"}, --- } Above lines works fine on my machines. Hoever, we have a line of { 6, -1, 16, "P6", }, below those lines, so we may not need the above 4 lines.
