[PATCH] tools/xentrace: decode RTDS priority in repl_budget records

Posted by Ryoji Okamoto 1 week, 6 days ago

The RTDS repl_budget trace record now contains the vCPU priority
level. Update xenalyze to account for the additional field and print
it when dumping the trace event.

Without this change, xenalyze interprets the record using the old
layout, causing the deadline and budget fields to be decoded from the
wrong offsets.
