WARNING
|
||||
This patch works with gcc versions 10.1+ and with kernel versions <5.7 and should
|
||||
NOT be applied when compiling on older versions of gcc due to key name changes
|
||||
of the march flags introduced with the version 4.9 release of gcc.[1]
|
||||
|
||||
Use the older version of this patch hosted on the same github for older
|
||||
versions of gcc.
|
||||
|
||||
FEATURES
|
||||
This patch adds additional CPU options to the Linux kernel accessible under:
|
||||
Processor type and features --->
|
||||
Processor family --->
|
||||
|
||||
The expanded microarchitectures include:
|
||||
* AMD Improved K8-family
|
||||
* AMD K10-family
|
||||
* AMD Family 10h (Barcelona)
|
||||
* AMD Family 14h (Bobcat)
|
||||
* AMD Family 16h (Jaguar)
|
||||
* AMD Family 15h (Bulldozer)
|
||||
* AMD Family 15h (Piledriver)
|
||||
* AMD Family 15h (Steamroller)
|
||||
* AMD Family 15h (Excavator)
|
||||
* AMD Family 17h (Zen)
|
||||
* AMD Family 17h (Zen 2)
|
||||
* Intel Silvermont low-power processors
|
||||
* Intel Goldmont low-power processors (Apollo Lake and Denverton)
|
||||
* Intel Goldmont Plus low-power processors (Gemini Lake)
|
||||
* Intel 1st Gen Core i3/i5/i7 (Nehalem)
|
||||
* Intel 1.5 Gen Core i3/i5/i7 (Westmere)
|
||||
* Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
|
||||
* Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
|
||||
* Intel 4th Gen Core i3/i5/i7 (Haswell)
|
||||
* Intel 5th Gen Core i3/i5/i7 (Broadwell)
|
||||
* Intel 6th Gen Core i3/i5/i7 (Skylake)
|
||||
* Intel 6th Gen Core i7/i9 (Skylake X)
|
||||
* Intel 8th Gen Core i3/i5/i7 (Cannon Lake)
|
||||
* Intel 10th Gen Core i7/i9 (Ice Lake)
|
||||
* Intel Xeon (Cascade Lake)
|
||||
* Intel Xeon (Cooper Lake)
|
||||
* Intel 3rd Gen 10nm++ i3/i5/i7/i9-family (Tiger Lake)
|
||||
|
||||
It also offers to compile passing the 'native' option which, "selects the CPU
|
||||
to generate code for at compilation time by determining the processor type of
|
||||
the compiling machine. Using -march=native enables all instruction subsets
|
||||
supported by the local machine and will produce code optimized for the local
|
||||
machine under the constraints of the selected instruction set."[3]
|
||||
|
||||
MINOR NOTES
|
||||
This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
|
||||
changes. Note that upstream is using the deprecated 'match=atom' flags when I
|
||||
believe it should use the newer 'march=bonnell' flag for atom processors.[2]
|
||||
|
||||
It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
|
||||
recommendation is to use the 'atom' option instead.
|
||||
|
||||
BENEFITS
|
||||
Small but real speed increases are measurable using a make endpoint comparing
|
||||
a generic kernel to one built with one of the respective microarchs.
