| Thread-topic: | [Xen-devel] Recent trace patch not arch-neutral |
> A recent patch to trace.c uses a call to rdtscll() which is > x86-specific. Is there an arch-neutral call that can be used > instead? Or do arch's need to implement this? (And if the > latter, should we choose a more generic name?) The tracebuffer code has always used the cycle counter, so if you've previously been compiling it for ia64 it must have previously been using some more arch neutral way of accessing it...
