+This patch has been tested on and known to work with kernel versions from 3.2 |
| 38 |
+up to the latest git version (pulled on 12/14/2013). |
| 39 |
+ |
| 40 |
+This patch will expand the number of microarchitectures to include new |
| 41 |
+processors including: AMD K10-family, AMD Family 10h (Barcelona), AMD Family |
| 42 |
+14h (Bobcat), AMD Family 15h (Bulldozer), AMD Family 15h (Piledriver), AMD |
| 43 |
+Family 16h (Jaguar), Intel 1st Gen Core i3/i5/i7 (Nehalem), Intel 2nd Gen Core |
| 44 |
+i3/i5/i7 (Sandybridge), Intel 3rd Gen Core i3/i5/i7 (Ivybridge), and Intel 4th |
| 45 |
+Gen Core i3/i5/i7 (Haswell). It also offers the compiler the 'native' flag. |
| 46 |
+ |
| 47 |
+Small but real speed increases are measurable using a make endpoint comparing |
| 48 |
+a generic kernel to one built with one of the respective microarchs. |
