Hmm, good question.
Yo, Steve, is there a way to do conditional things in a TP?
For example:
@@ -83,7 +87,8 @@ TRACE_EVENT(mce_record,
__entry->walltime,
__entry->socketid,
__entry->apicid,
- __entry->microcode)
+ __entry->microcode,
if (boot_cpu_data.x86_vendor == X86_VENDOR_AMD)
__print_array(__get_dynamic_array(v_data), __entry->len / 8, 8))
i.e., print that array only when on a AMD.
I'm sure this won't fly as it is macro magic - this is just to show the
intent...
Thx.
