FEATURES
This patch adds additional tunings via new x86-64 ISA levels and
more micro-architecture options to the Linux kernel in three classes.
1. New generic x86-64 ISA levels
These are selectable under:
Processor type and features ---> x86-64 compiler ISA level
• x86-64 A value of (1) is the default
• x86-64-v2 A value of (2) brings support for vector
instructions up to Streaming SIMD Extensions 4.2 (SSE4.2)
and Supplemental Streaming SIMD Extensions 3 (SSSE3), the
POPCNT instruction, and CMPXCHG16B.
• x86-64-v3 A value of (3) adds vector instructions up to AVX2, MOVBE,
and additional bit-manipulation instructions.
There is also x86-64-v4 but including this makes little sense as
the kernel does not use any of the AVX512 instructions anyway.
Users of glibc 2.33 and above can see which level is supported by running:
/lib/ld-linux-x86-64.so.2 --help | grep supported
Or
/lib64/ld-linux-x86-64.so.2 --help | grep supported
2. New micro-architectures
These are selectable under:
Processor type and features ---> Processor family
• 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)
• AMD Family 19h (Zen 3)**
• AMD Family 19h (Zen 4)‡
• AMD Family 1Ah (Zen 5)§
• 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)*
• Intel 4th Gen 10nm++ Xeon (Sapphire Rapids)†
• Intel 11th Gen i3/i5/i7/i9-family (Rocket Lake)†
• Intel 12th Gen i3/i5/i7/i9-family (Alder Lake)†
• Intel 13th Gen i3/i5/i7/i9-family (Raptor Lake)‡
• Intel 14th Gen i3/i5/i7/i9-family (Meteor Lake)‡
• Intel 5th Gen 10nm++ Xeon (Emerald Rapids)‡
Notes: If not otherwise noted, gcc >=9.1 is required for support.
*Requires gcc >=10.1 or clang >=10.0
**Required gcc >=10.3 or clang >=12.0
†Required gcc >=11.1 or clang >=12.0
‡Required gcc >=13.0 or clang >=15.0.5
§Required gcc >14.0 or clang >=19.0?
3. Auto-detected micro-architecture levels
Compile by passing the '-march=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."[1]
Users of Intel CPUs should select the 'Intel-Native' option and users of AMD
CPUs should select the 'AMD-Native' option.
MINOR NOTES RELATING TO INTEL ATOM PROCESSORS
This patch also changes -march=atom to -march=bonnell in accordance with the
gcc v4.9 changes. 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.[3] 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.
See the following experimental evidence supporting this statement:

REQUIREMENTS
linux version 6.8-rc3+
gcc version >=9.0 or clang version >=9.0

Subject: ZEN: Restore CONFIG_OPTIMIZE_FOR_PERFORMANCE_O3
This reverts a6036a41bffba3d5007e377483b425d470ad8042 (kbuild: drop
support for CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3), removes the
dependency on CONFIG_ARC and adds RUSTFLAGS.
