In particular, the meta-intel layer will undergo some major refactoring once this is merged. We believe it is of value to keep as much of the tune files available in oe-core as possible, rather than isolating them all in meta-intel. This series renames the x86-related tune files, documents best practices, updates the core2 tune file, adds a corei7 tune file, and updates the dependent machine configs. This spans oe-core and poky and I feel is best viewed as a whole. Please forgive the cross-post. The new corei7 tune file applies to Nehalem and Silvermont (Bay Trail) CPUs which support up to SSE4.2. This provides an appropriate demarcation line while maximizing compatibility as well as including optimal support for the current generation of the embedded CPUs (Bay Trail) by including it in the new tune. AVX (Sandy Bridge and beyond) is not included as that would not apply to Bay Trail, although it can easily be added in a corei7-avx tune file as an additional patch for users who care more about the last few percent of performance over compatibility and consolidation. An important note and likely a point of contention: The core2 update changes the core2 arch to core2-32, making the 32 bit explicit rather than implied in order to provide a consistent naming scheme going forward with newer tunes where 64 bit would be logical assumption if not explicitly stated. See patch 5/15 for details on this bit. Finally, update the machines dependent on these tune files to use the new names. As we remove x86_64, the 64b x86 machines now build as core2-64 for maximum compatibility. For reference, the corei7-64 tune defines: TARGET_CC_ARCH=" -m64 -march=corei7 -mtune=corei7 -mfpmath=sse -msse4.2" While the corei2-32 tune defines: TARGET_CC_ARCH=" -m32 -march=core2 -mtune=core2 -msse3 -mfpmath=sse" The following changes since commit 6e7047434fc1570146ebc94254412b99b1c4cab4: poky.ent: Fixed broken OE_LISTS_URL.
