Description Clark Williams 2013-05-13 19:10:28 UTC

Description of problem:

CONFIG_NETCONSOLE and CONFIG_NETCONSOLE_DYNAMIC should be configured 
for all variants of the 3.6 realtime kernel

Comment 1 John Kacur 2013-06-13 20:10:09 UTC

Symbol: NETCONSOLE [=n]
Type : tristate
Prompt: Network console logging support
Defined at drivers/net/Kconfig:154
Depends on: NETDEVICES [=y] && NET_CORE [=y] && !PREEMPT_RT_FULL [=y]
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Network core driver support (NET_CORE [=y])

CONFIG_NETCONSOLE_DYNAMIC:

This option enables the ability to dynamically reconfigure target
parameters (interface, IP addresses, port numbers, MAC addresses)
at runtime through a userspace interface exported using configfs.
See <file:Documentation/networking/netconsole.txt> for details.

Symbol: NETCONSOLE_DYNAMIC [=n]
Type : boolean
Prompt: Dynamic reconfiguration of logging targets
Defined at drivers/net/Kconfig:161
Depends on: NETDEVICES [=y] && NET_CORE [=y] && NETCONSOLE [=n] && SYSFS [=y] && CONFIGFS_FS [=m] && (NETCONSOLE [=n]!=y || CONFIGFS_FS [=m]!=m)
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Network core driver support (NET_CORE [=y])
-> Network console logging support (NETCONSOLE [=n])

So, NETCONSOLE_DYNAMIC depends on NETCONSOLE, which cannot be configured for
 PREEMPT_RT_FULL
