Since "net/i40e: use dynamic log type for control logs", the
i40e driver is more verbose by default, which could result in
testpmd being flooded by log messages in some conditions:
Checking link statuses...
i40e_dev_handle_aq_msg(): Request 2561 is not supported yet
i40e_dev_handle_aq_msg(): Request 2561 is not supported yet
i40e_dev_handle_aq_msg(): Request 2561 is not supported yet
i40e_dev_handle_aq_msg(): Request 2561 is not supported yet
Port 0 Link Up - speed 40000 Mbps - full-duplex
Port 1 Link Up - speed 40000 Mbps - full-duplex
Done
testpmd> i40e_dev_handle_aq_msg(): Request 4097 is not supported yet
i40e_dev_handle_aq_msg(): Request 4097 is not supported yet
i40e_dev_handle_aq_msg(): Request 4097 is not supported yet
Fix this by disabling the dynamic logs by default. It is still
possible to enable them at runtime.

IMHO, if this is a problem, then we should surely not be hiding and ignoring the error. If it's not a problem, then the log level should be reduced to a lower level, e.g. INFO or NOTICE. Alternatively, this code could be modified to only print an error once for each unsupported request type. Ideally both solutions should be used, I think. I'm not sure I like setting the default log level to just show EMERG messages. Regards, /Bruce ^ permalink raw reply [flat|nested] 12+ messages in thread

Yes, now that these logs are not stripped at compilation, we should do an effort to have the proper default log value (notice, warning, error?), and have the proper log level on each log, depending on its criticality and maybe its frequency (maybe we'll want to rate limit the logs in the future). This is a more global discussion, which is not especially related to i40e (the only part of code that currently use dynamic logs). Olivier ^ permalink raw reply [flat|nested] 12+ messages in thread

This mail to explain how important it is to configure his mailer. You need to quote the original mail so we can quickly find what you have replied. It is also a problem for patchwork as it creates a new entry: http://dpdk.org/dev/patchwork/patch/23300/ because it thinks it is a new patch. So your ack is not registered in the original patch entry: http://dpdk.org/dev/patchwork/patch/23298/ Please share this explanation, thanks 2017-04-06 14:31, Zhang, Helin: > > -----Original Message----- > From: Olivier Matz [mailto:olivier.matz@6wind.com] > Sent: Thursday, April 6, 2017 10:17 PM > To: dev@dpdk.org > Cc: Zhang, Helin <helin.zhang@intel.com>; Wu, Jingjing <jingjing.wu@intel.com>; Richardson, Bruce <bruce.richardson@intel.com>; Yigit, Ferruh <ferruh.yigit@intel.com> > Subject: [PATCH] net/i40e: disable init and driver logs by default > > Since "net/i40e: use dynamic log type for control logs", the i40e driver is more verbose by default, which could result in testpmd being flooded by log messages in some conditions: > > Checking link statuses... > i40e_dev_handle_aq_msg(): Request 2561 is not supported yet > i40e_dev_handle_aq_msg(): Request 2561 is not supported yet > i40e_dev_handle_aq_msg(): Request 2561 is not supported yet > i40e_dev_handle_aq_msg(): Request 2561 is not supported yet > Port 0 Link Up - speed 40000 Mbps - full-duplex > Port 1 Link Up - speed 40000 Mbps - full-duplex > Done > testpmd> i40e_dev_handle_aq_msg(): Request 4097 is not supported yet > i40e_dev_handle_aq_msg(): Request 4097 is not supported yet > i40e_dev_handle_aq_msg(): Request 4097 is not supported yet > > Fix this by disabling the dynamic logs by default.
