4.2.1. | Does FreeBSD support architectures other than the x86? |
Yes. FreeBSD divides support into multiple tiers. Tier 1 architectures, such as i386 or amd64; are fully supported. Tiers 2 and 3 are supported on a best-effort basis. A full explanation of the tier system is available in the Committer's Guide. A complete list of supported architectures can be found on the platforms page. | |
4.2.2. | Does FreeBSD support Symmetric Multiprocessing (SMP)? |
FreeBSD supports symmetric multi-processor (SMP) on all non-embedded platforms (e.g, i386, amd64, etc.). SMP is also supported in arm and MIPS kernels, although some CPUs may not support this. FreeBSD's SMP implementation uses fine-grained locking, and performance scales nearly linearly with number of CPUs. smp(4) has more details. | |
4.2.3. | What is microcode? How do I install Intel® CPU microcode updates? |
Microcode is a method of programmatically implementing hardware level instructions. This allows for CPU bugs to be fixed without replacing the on board chip. Install sysutils/devcpu-data, then add: microcode_update_enable="YES" to |
