When doing long term recording and waiting for some event
to snapshot on, we often only care about the last minute or so.
--switch-output supports rotating the perf.data file when the
size exceeds a threshold. But the disk would still be filled
with unnecessary old files.
Add a

The -c option to enable multiplex scaling has been useless for quite some
time because scaling is default. It's only useful as --no-scale to
disable scaling. But the non scaling code path has bitrotted
and doesn't print anything because perf output code
relies on value run/ena in

When -r is used memory would get corrupted because the evsel->id array
would get overrun. evsel->ids is a running counter of the last id.
Normally this works fine, but with -r the same event is initialized
multiple times, but not this counter, so it would keep growing

When comparing time stamps in perf script traces it can be annoying
to work with the full perf time stamps. Add a --reltime option
that displays time stamps relative to the trace start to make
it easier to read the traces.
Note: not currently supported for --time. Report an erro

Seems like commit 9b6f7e7a296e17990aae298c809b001e99ddd151 introduced
NULL pointer dereference for ca0132 codec.
When ca0132 loads firmware, snd_hdac_stream_start is called with
azx_dev->substream being NULL.
This patch calls snd_hdac_get_stream_stripe_ctl only when
azx_dev->substream is not NULL
For ca0132 codec, azx_dev->stream is NULL during firmware loading.
Calling snd_hdac_get_stream_stripe_ctl unconditionally causes NULL
pointer dereference in that function.
