We typically do not want to enable this. What options is
this triggering that are essential to the IPC config ?
Configuration "POSIX_MQUEUE" depends on "CONFIG_EXPERIMENTAL=y", so it
should be enabled.
This configuration has been enabled in
meta/cfg/kernel-cache/ktypes/base/base.cfg
#
# Code maturity level options
#
CONFIG_EXPERIMENTAL=y
But it was redefined in
meta/cfg/kernel-cache/bsp/routerstationpro/routerstationpro.cfg
#
# General setup
#
# CONFIG_EXPERIMENTAL is not set
So CONFIG_EXPERIMENTAL is not set in the final kernel config.
I also can find the redefinition in
.../meta/cfg/yocto/standard/routerstationpro/redefinition.txt
Value of CONFIG_EXPERIMENTAL is redefined by fragment

These options are already provided by the base configuration
and are supposed to be baseline options for any BSP. Can
you elaborate on why you needed these here ?
These options also were redefined in
meta/cfg/kernel-cache/bsp/routerstationpro/routerstationpro.cfg
# CONFIG_SYSVIPC is not set
# CONFIG_BSD_PROCESS_ACCT is not set
So these options were disabled in kernel configure file. But they are
needed by LTP test.
I took a look at the routerstationpro.cfg and found that it is a
complete configure file. It is different
from other BSPs. So I think we should modify routerstationpro.cfg and
only leave some special platform,
hardware configure options in it. Or at least we should omit the above
options which conflict with
the base configurations.
