Hi Perf experts, What¹s your opinion regarding tracing support (e.g. Performance counters, hardware debug features) in x86 processors developed by AMD and Intel.
I¹m interested in whether the common tracing tools (perf, oprofile, systemtap, lltng etc etc) are more mature on AMD¹s or Intel¹s systems (or perhaps it doesn¹t matter?), and whether there are any processor models that are particularly well supported or should be avoided. For example, I¹m considering a machine with an AMD A10 series processor or alternatively an Intel i5 series processor. Just to be clear, I¹m not trying to start a flame-war here! My question is specific to tracing tooling support and not to relative performance, price or purchasing philosophy. (Full disclosure: I worked for AMD for quite a while, so I¹d prefer one of their machines, but ultimately I¹ll use whatever¹s got the best tool support. I could conceivably be convinced to contribute to support for AMDs systems, but that¹s another conversation!).
