Enabling debug logs in dpdk can be a challenge to be sure of what is actually enabled, add commands to list and change those log levels. However, these commands do not help when tracking issues in dpdk init itself: dump log levels right after init. Example: $ ovs-appctl dpdk/log-list global log level is debug id 0: lib.eal, level is info id 1: lib.malloc, level is info id 2: lib.ring, level is info id 3: lib.mempool, level is info id 4: lib.timer, level is info id 5: pmd, level is info [...] id 37: pmd.net.bnxt.driver, level is notice id 38: pmd.net.e1000.init, level is notice id 39: pmd.net.e1000.driver, level is notice id 40: pmd.net.enic, level is info [...] $ ovs-appctl dpdk/log-set debug pmd.*:notice $ ovs-appctl dpdk/log-list global log level is debug id 0: lib.eal, level is debug id 1: lib.malloc, level is debug id 2: lib.ring, level is debug id 3: lib.mempool, level is debug id 4: lib.timer, level is debug id 5: pmd, level is debug [...] id 37: pmd.net.bnxt.driver, level is notice id 38: pmd.net.e1000.init, level is notice id 39: pmd.net.e1000.driver, level is notice id 40: pmd.net.enic, level is notice [...] Signed-off-by: David Marchand <david.marchand@redhat.com> Signed-off-by: Ilya Maximets <i.maximets@ovn.org>

.SS "DPDK COMMANDS"
|
|
These commands manage DPDK components.
|
|
.IP "\fBdpdk/log-list\fR"
|
|
Lists all DPDK components that emit logs and their logging levels.
|
|
.IP "\fBdpdk/log-set\fR [\fIspec\fR]"
|
|
Sets DPDK components logging level. Without any \fIspec\fR, sets the logging
|
|
\fBlevel\fR for all DPDK components to \fBdebug\fR. Otherwise, \fIspec\fR is a
|
|
list of words separated by spaces: a word can be either a logging \fBlevel\fR
|
|
(\fBemergency\fR, \fBalert\fR, \fBcritical\fR, \fBerror\fR, \fBwarning\fR,
|
|
\fBnotice\fR, \fBinfo\fR or \fBdebug\fR) or a \fBpattern\fR matching DPDK
|
|
components (see \fBdpdk/log-list\fR command on \fBovs\-appctl\fR(8)) separated
|
|
by a colon from the logging \fBlevel\fR to apply.
