[dpdk-dev] rte_malloc

[dpdk-dev] rte_malloc

[Mahdi Moradmand Badie]

Hello All,

I had a problem regarding use the rte_malloc.
I want to know if I want to use rte_malloc instead of malloc just mak
change like this
struct lcore_params *p = malloc
<http://dpdk.org/doc/api/rte__malloc_8h.html#afb7316a4ec228ed9b8ffc1864b03d85b>
(sizeof(*p)); ==>
struct lcore_params *p = rte_malloc
<http://dpdk.org/doc/api/rte__malloc_8h.html#afb7316a4ec228ed9b8ffc1864b03d85b>(NULL,
sizeof(*p), 0);
is enough ?

Because I have problem and Segmentation fault (core dumped) ??
Thanks in advance,

Yes, malloc(sizeof(*p)) has an equivalent behavior to rte_malloc(NULL, 
sizeof(*p), 0)
in the context of a DPDK application.

Could you provide more details of how to reproduce or could you try to
reproduce your problem using a very simple example like 
examples/helloworld ?

Thanks Sergio,
Yes sure,
I attached files, it seems so easy but doesn't work.

Forgot to ask,

What's the command line you are using to run the app?

Have you tried to run the unit tests? (Run 'app/test' application, then 
'malloc_autotest')

Re: [dpdk-dev] rte_malloc

[Sergio Gonzalez Monroy]

Ok.

So if you build DPDK from the sources, you would have an 'app' directory 
in you build directory.
You can read the Getting Started Guide for more info:
http://dpdk.readthedocs.io/en/v16.04/linux_gsg/index.html

Once you ran the 'test' DPDK application (located inside the 'app' 
directory) you would get a shell where you can run different kind of 
autotests/tests. One of them is the 'malloc_autotest'.

Let me know the result of running that test.
