Revision as of 09:32, December 20, 2014
This section lists the CPU-optimized Funtoo Linux builds currently available for download for intel64-haswell. The intel64-haswell subarch specifically supports processors based on Intel's Haswell microarchitecture. Haswell desktop processors are branded as 4th Generation Intel Core i3, Core i5, and Core i7 Processors.
No downloadable stage builds are currently available for this sub-architecture.
The intel64-haswell subarch specifically supports processors based on Intel's Haswell microarchitecture. Haswell desktop processors are branded as 4th Generation Intel Core i3, Core i5, and Core i7 Processors..
Architecture and Optimization
The following settings are applied to all stages for this subarch via Funtoo subarch profiles:
| CHOST | x86_64-pc-linux-gnu |
| CFLAGS | -march=core-avx2 -O2 -pipe |
The intel64-haswell subarch specifically supports processors based on Intel's Haswell microarchitecture. Haswell desktop processors are branded as 4th Generation Intel Core i3, Core i5, and Core i7 Processors. Many of the released processors are APUs, containing integrated Intel graphics support. Haswell Xeon processors include the Xeon E5 v3 Family.
One of the new instruction sets with this subarch is AVX2 (Advanced Vector Extensions 2), also known as Haswell New Instructions, introduced June of 2013, as an expansion of the AVX instruction.
Intel AVX instructions require operating system support and have been in the Linux kernel since 2.6.30. Additionally, they require slightly more power to execute. When executing these instructions, the processor may run at less than the marked frequency to maintain thermal design power (TDP) limits. For more information about these instructions, see this link.
