[dpdk-dev] [PATCH 0/2] Intel driver silence excess logging

[Stephen Hemminger]

The Intel drivers seem to be getting more verbose in the log with
each release. This is not a good thing.

[dpdk-dev] [PATCH 1/2] ixgbe: silence noisy log messages

[Stephen Hemminger]

The ixgbe driver likes to be far to chatty in the system log
which is good for the original developer but not good for a production
product.

Reduce the log spam by doing:
 * All the normal messages should be changed from INFO to DEBUG.
 * The log messages should be done with RTE_LOG so that they can be
   compiled out if RTE_LOG_LEVEL is set.
 * The link state print routine prints more than is necessary
   PCI information is already known (earlier in log) and has
   no purpose here.

This patch is broken.

The changes are there twice.
I removed the first part of the mail.

Well, I would say that PMD_INIT_LOG should not be called from here.
PMD_DRV_LOG should be the preferred macro (pure debug stuff, out of init).


The rest looks fine to me.

[dpdk-dev] [PATCH 2/2] e1000: silence noisy log messages

[Stephen Hemminger]

Same as ixgbe. Should not be as chatty in log and should be
possible to compile away all the debug messages.

And same as ixgbe patch.

Patch is broken.
Macro in interrupt handler can be changed to PMD_DRV_LOG.

These changes could be applied to other pmds for consistency, not only 
e1000 and ixgbe.

[dpdk-dev] [PATCH 0/2] fix logging in Intel PMD's

[Stephen Hemminger]

The Intel Poll Mode Drivers generate a lot of log messages and
they are mostly at the INFO logging level. This should be changed
to the common syslog conventions, ie. put unimportant stuff for
production users at DEBUG level and things of interest but not
errors at NOTICE level.

Also should use RTE_LOG not rte_log so that messages can be
compiled out.

[dpdk-dev] [PATCH 1/2] ixgbe: silence noisy log messages

[Stephen Hemminger]

The ixgbe driver likes to be far to chatty in the system log
which is good for the original developer but not good for a production
product.

Reduce the log spam by doing:
 * All the normal messages should be changed from INFO to DEBUG.
 * The log messages should be done with RTE_LOG so that they can be
   compiled out if RTE_LOG_LEVEL is set.
 * The link state print routine prints more than is necessary
   PCI information is already known (earlier in log) and has
   no purpose here.

As suggested by Thomas before, I think you need to put the rework of logs into another
separate patch, but not combined together with the replacing INFO with DEBUG.
This is common for all of this patch set.
