 i have divided eal_common.c (new file which was added in v1 PATCH)
into eal_common_system.c and eal_common_runtime.c and have moved
appropriate functions into it. If file names are not appropriate or changes
are not worth doing the split, I will merge them back into
eal_common_config.c.

Thanks.

Please do not forget v4 word and changelog when sending patches.
Check http://dpdk.org/dev#send

You are already doing big changes. So let's iterate with existing files and
avoid creating new ones.
eal_common_options.c must be kept. But if some code is not really related to
runtime options, we could consider adding a new file eal_common_config.c, not
sure about this one.

I don't agree with these new files.
We must try to keep a semantic organization. The file eal_common_options.c
would be better for option-related functions.
Maybe that the split between system config, runtime config and internal config
must be reworked.

By the way, it would be nice to avoid extern variables.

 I have taken care of your comments and will generate v4 patch.
Currently I have moved common functions in eal.c into
"eal_common_system_options.c" file. Are you suggesting that we further
divide "eal_common_options.c" and "eal_common_system_options.c(new file
added)" into 3 separate files i.e.

eal_common_system_options.c
eal_common_runtime_options.c
eal_common_internal_options.c

Thanks.

Thanks Thomas for the reviews, do you want me to send "v4" version of this
patch series or start a different patch series?

Thanks,
Ravi

[dpdk-dev] [PATCH 4/7] Move EAL common functions

2014-12-25 Thread Ravi Kerur
Move common functions in eal.c to librte_eal/common directory.
Use RTE_EXEC_ENV_BSDAPP to differentiate minor differences in
common functions.
Makefile changes to reflect new file.
Fix checkpatch warnings and errors.
