12 years agoPre-assign fixed loglevels
Mathieu Desnoyers [Wed, 1 Feb 2012 22:54:50 +0000 (17:54 -0500)] 
Pre-assign fixed loglevels

Some early LTTng-UST adopters brought to my attention that the way
tracepoint loglevels are currently specified in LTTng-UST might be too
relax for its own good. If each application define their own loglevel
names/values, it will become difficult to use the loglevels to select
"trace verbosity" in a system-wide manner.

Now that I come to think of it, it might make sense to pre-define a set
of supported loglevels, similarly to syslog(3). However, given that
tracing sometimes targets debug levels that are more fine-grained than
in the case of logs, I would propose to split the "debug" loglevel into
sub-categories.

My current thought is to simply just allow these loglevels. I doubt that
letting application developers specify extra loglevels on top of this
would be that useful, and it would certainly be more confusing.

In the list below, lower numbers means "low verbosity", higher numbers
means "high verbosity, debug-style information".

Force 64-bit timestamps

commit 9080554ff25b08f48762d2ee7cfa3981317e9c1d attempted to fix the
timestamp problem by using large event headers. It incorrectly stated
that those headers "use a 64-bit timestamp field". In fact, they use a
32-bit timestamp field (not 64). So they were helping (it was better
than using a 27-bit field), but the problem could still appear. It's
only when the RING_BUFFER_RFLAG_FULL_TSC is set that the ring buffer
forces use of the 64-bit fields.

Fix this for good by setting this flag.
