[PATCH 0/3] hw: Remove dynamic field width from trace event

Posted by Philippe Mathieu-Daudé 4 years, 5 months ago

Eric noted in [1] the dtrace via stap backend can not support
the dynamic '*' width format.
I'd really like to use dynamic width in trace event because the
read/write accesses are easier to read but it is not a priority.
Since next release is close, time to fix LP#1844817 [2].
