slaxemulator@7775 1 On linux platforms, grok /proc/cpuinfo for the CPU/vendor info.
slaxemulator@7775 2
slaxemulator@7775 3 Prob not suitable for upstream seeing as how it's 100% linux-specific
slaxemulator@7775 4 http://lists.gnu.org/archive/html/bug-coreutils/2005-09/msg00063.html
slaxemulator@7775 5
slaxemulator@7775 6 Patch originally by Carlos E. Gorges <carlos@techlinux.com.br>, but
slaxemulator@7775 7 heavily reworked to suck less.
slaxemulator@7775 8
slaxemulator@7775 9 To add support for additional platforms, check out the show_cpuinfo()
slaxemulator@7775 10 func in the linux/arch/<ARCH>/ source tree of the kernel.
