There are some pending patches which requires to factorize some EAL parts
in order to be correctly implemented.
This patchset do the required clean-up and rework these patches to improve
lcore handling:
Didier Pallard (2):
eal: add core list input format
config: support 128 cores
Patrick Lu (1):
eal: get relative core index
Simon Kuenzer (1):
eal: add option --master-lcore
Thomas Monjalon (6):
eal: move internal headers in source directory
eal: factorize common headers
eal: fix header guards
eal: factorize internal config reset
eal: factorize options sanity check
eal: factorize configuration adjustment

Remove process_type adjustment in rte_config_init() because it is already done in eal_parse_args(). eal_proc_type_detect() is kept duplicated because it open a file descriptor which is used later in each eal.c.

I prefer this scheme of using a new flag for this method of specifying the cores to use. If you don't want to use up a single-letter option, two alternatives: 1) use a long option instead. 2) if the -c parameter includes a "-" or a ",", treat it as a new-style option, otherwise treat as old. The only abiguity here would be for specifying a single core value 1-9 e.g. is "-c 6" a mask with two bits, or a single-core to run on. [0 is obviously a named core as it's an invalid mask, and A-F are obviously masks.] If we did want this scheme, I would suggest that we allow trailing commas in the list specifier, so we can force users to clear ambiguity by either writing "0x6" or "6," i.e. disallow ambiguous values to avoid problems. However, this is probably more work that it's worth to avoid using up a letter option. I'd prefer any of these options to breaking backward compatibility in this case. /Bruce > > Signed-off-by: Didier Pallard <didier.pallard-pdR9zngts4EAvxtiuMwx3w@public.gmane.org> > > Signed-off-by: Thomas Monjalon <thomas.monjalon-pdR9zngts4EAvxtiuMwx3w@public.gmane.org> > > --- > > app/test/test_eal_flags.c | 28 ++++++++++- > > lib/librte_eal/common/eal_common_options.c | 81 ++++++++++++++++++++++++++++-- > > 2 files changed, 103 insertions(+), 6 deletions(-) > > > > diff --git a/app/test/test_eal_flags.c b/app/test/test_eal_flags.c > > index 1f95d7f..5ad89c5 100644 > > --- a/app/test/test_eal_flags.c > > +++ b/app/test/test_eal_flags.c > > @@ -484,7 +484,7 @@ test_invalid_r_flag(void) > > } > > > > /* > > - * Test that the app doesn't run without the coremask flag.

It was the initial proposal (in April): http://dpdk.org/ml/archives/dev/2014-April/002173.html And I liked keeping only 1 option; http://dpdk.org/ml/archives/dev/2014-May/002722.html But Anatoly raised the compatibility problem: http://dpdk.org/ml/archives/dev/2014-May/002723.html Then there was no other comment so Didier and I reworked a separate option. > The existing coremask parsing always assumes a hex coremask, so just looking > for a 0x will not work.

We need a consensus here. Who is supporting a "burn" of an one-letter option with clear usage? Who is supporting a "re-merge" of the 2 syntaxes with more complicated rules (list syntax is triggered by presence of "-" or ",")? Please vote quickly.

I would still prefer a long option (we already have a coremask parameter, so another one is kind-of non-essential and IMO shouldn't belong in a scarce resource of one-letter parameters), but if everyone else agrees, the "burn" option is much more preferable to me than complicating syntax of an already existing parameter.

Short options are not only scarse on their own, but they also have to potentially comingle with options parsed by an application building on the DPDK. At least with a long option the chances of a conflict are lessened. Neil > Thanks, > Anatoly > ^ permalink raw reply [flat|nested] 40+ messages in thread

That would allow you to do: rte_eal_remote_launch(func0, arg0, rte_lcore_with_index(0)); rte_eal_remote_launch(func1, arg1, rte_lcore_with_index(1)); ...

Even simpler, I can fix it by introducing a flag master_lcore_parsed and do the adjustment only if the option is not parsed. -- Thomas ^ permalink raw reply [flat|nested] 40+ messages in thread

In that case, having it as a short option makes a lot of sense. /Bruce ^ permalink raw reply [flat|nested] 40+ messages in thread
