[PATCH] app/dma-perf: calrify incorrect NUMA config

[Vipin Varghese]

Current commit decalres either `source or destination numa is greater
than acture numa` as cause of error. Rephrase as `Source or Destination`
is incorrect numa by checking which is greater than available numa.

There are three cases to invoking:
1) src_numa_node >= nr_sockets
2) dst_numa_node >= nr_sockets
3) both src_numa_node and dst_numa_node >= nr_sockets

It could cover cases 1&2 in your commit, but could not cover case 3.

So I think we should keep original implement.

Thanks

Thank you for comments, please find my reasoning as `change is added to 
address spelling issue of acture numa to available numa`

> There are three cases to invoking:
> 1) src_numa_node >= nr_sockets

As per my testing, following scenarios are explored

1) if src-numa is incorrect, we get error message as `source is 
incorrect numa`

2) if dst-numa is incorrect, we get error message as `destination is 
incorrect numa`

3) if both src-numa and dst-numa are incorrect, we get error as `source 
is incorrect numa`, fixing source and rerunning `destination is 
incorrect numa` (which is expected)

I am happy to make changes to reflect the third scenario also. But 
please note as shared, the real intention is to fix ` acture numa` to 
something meaningful.
> So I think we should keep original implement.

I humbly disagree, based on the explanation as shared above. I can share 
v2 patch to address

1. acture numa

2. soruce or destination or src & destination

[PATCH v2] app/dma-perf: calrify incorrect NUMA config

[Vipin Varghese]

In case incorrect NUMA configuration, the current commit shares
 1) either `source or destination numa is greater`
 2) instead of `actual NUMA` it is `acture NUMA`

Current changes helps to rectify the same by using `PRINT_ERR` instead
of printf.

Signed-off-by: Vipin Varghese <vipin.varghese@amd.com>

Changes:
 - inform incorrect numa
 - fix spelling from acture to actual
 - use PRINT_ERR instead of printf

The naming style needs to be adjusted, how about
bool is_src_numa_exceed, is_dst_numa_exceed;

And predefine the variable at the beginning of function, sort by length, some like:

	bool is_src_numa_exceed, is_dst_numa_exceed;
	unsigned int buf_size = cfg->buf_size.cur;
	uint32_t nr_buf = cfg->nr_buf;
	unsigned int nr_sockets;

	nr_sockets = rte_socket_count();
	is_src_numa_exceed =
	is_dst_numa_exceed =
	if (xxx)
		...

Please don't capitalize the first letter of "Source" and "Destination"

Ok, the naming convention used by me is `CamelCase`. One suggested from 
your end is `snake_case`.

Does DPDK has a constrain it can not use CamelCase.

[PATCH v3] app/dma-perf: calrify incorrect NUMA config

[Vipin Varghese]

In case incorrect NUMA configuration, the current commit shares
 1) either `source or destination numa is greater`
 2) instead of `actual NUMA` it is `acture NUMA`
 3) uses `printf` instead of PRINT_ERR

current patch changes the above to
 1) identify if source or|and destination is incorrect
 2) fix wording to incorrect
 3) use PRINT_ERR macro

Signed-off-by: Vipin Varghese <vipin.varghese@amd.com>

V3 changes:
 - use snake-case instead of camel case for static scope functions.
 - convert console words to lower case.

V2 changes:
 - inform incorrect numa
 - fix spelling from acture to actual
 - use PRINT_ERR instead of printf
