regmap: Add trace event for successful cache reads

2012-03-05T15:55:14+00:00

Currently we only trace physical reads, there's no instrumentation if
the read is satisfied from cache.

x86_64 warns as size_t is not an int.

regmap: Add basic tracepoints

2011-08-08T06:56:16+00:00

Trace single register reads and writes, plus start/stop tracepoints for
the actual I/O to see where we're spending time. This makes it easy to
have always on logging without overwhelming the logs and also lets us take
advantage of all the context and time information that the trace subsystem
collects for us.

We don't currently trace register values for bulk operations as this would
add complexity and overhead parsing the cooked data that's being worked
with.
