Whether an asm would work would depend more on the compiler than on the OS;
...but, then again, maybe the OS has already done all the heavy lifting for you: $ uname -sr Darwin 12.2.1 $ sysctl machdep.cpu.brand_string machdep.cpu.brand_string: Intel(R) Core(TM) i7-3820QM CPU @ 2.70GHz I.e, on OS X, you can use sysctl() to get the brand string, at least on some x86 processors. On FreeBSD 7 and 9, and OpenBSD 4.8, at least, hw.model gives you that information (it gives you the *system* model, e.g. MacBookPro10,1, on OS X). On NetBSD 5.1, machdep.cpu_brand does it. On at least some versions of Linux: $ uname -sr Linux 2.6.22-16-generic $ egrep 'model name' /proc/cpuinfo model name : Intel(R) Core(TM) i7-3820QM CPU @ 2.70GHz model name : Intel(R) Core(TM) i7-3820QM CPU @ 2.70GHz The virtual machine in question is, to quote VMware, "configured to use: 2 processor cores"; I don't know whether that means that it looks like a single chip with two cores, or two separate chips, and I don't know whether Linux reports one or N model names for a single N-core chip. Do we want to report the number of CPU cores? (I don't know if any SMP machines have a mix of different CPU models, so I don't know if we need to worry about reporting multiple brand strings.) ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
