Hi group members,
I'm new to this list and recently started to work on a shine new TS-7800 board.
The application we are going to develop is supposed to use POSIX
message queues as the chosen inter-process communication method. I'm
in the need to perform some compatibility and latency test on this
API, but I was unable to run a simple example program to create a
message queue on the default Linux system that comes with TS-7800.
The error I got was: "Function not implemented"
After some searching on the list archive and further investigation on
default kernel config file ([1]: relevant part pasted below), I'm
supposing POSIX message queues are disabled in the TS-7800 kernel
itself. If this is the truth, the following question arises. Why are
they disabled by default in the kernel config? What kind of
difficulties am I supposed to meet in order to enable back this
functionality? Are there any known compatibility or performance issue
with POSIX mqueues?
---------- taken from default kernel config -------------
#
# General setup
#
CONFIG_SYSVIPC=y
# CONFIG_IPC_NS is not set
CONFIG_SYSVIPC_SYSCTL=y
# CONFIG_POSIX_MQUEUE is not set
-----------------------------------------------------------------
Thanks in advance!
Regards,
Andrea
