[dpdk-dev] Assembly code

[Mahdi Moradmand Badie]

Dear All,

I used the default format of Makefile (as follow) which is available in the
examples,
I was wondering how I could generate the assembly (main.s) related to my
main.c, via Makefile.

PS. using -S doesn't work :(

ifeq ($(RTE_SDK),)
$(error "Please define RTE_SDK environment variable")
endif

# Default target, can be overriden by command line or environment
RTE_TARGET ?= x86_64-native-linuxapp-gcc

include $(RTE_SDK)/mk/rte.vars.mk

# binary name
APP = Mahdi_test

INC += $(wildcard include/*.h)

# all source are stored in SRCS-y
SRCS-y := main.c

CFLAGS += $(WERROR_FLAGS) -I $(SRCDIR)/include -I/usr/local/include

EXTRA_CFLAGS += -O3
EXTRA_CFLAGS += -Wno-error
EXTRA_CFLAGS += -std=c99

# rte.extapp.mk : External application
include $(RTE_SDK)/mk/rte.extapp.mk

[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

(sizeof(*p)); ==>
struct lcore_params *p = rte_malloc
(NULL,
sizeof(*p), 0);
is enough ?

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

[dpdk-dev] Multiple Ring for Multiple Cores

[Mahdi Moradmand Badie]

Dear All,

I have a written code which doesn't work like I want,

I wanna have a separate ring_buffer for each core (each core has its own
ring),
So I have a 2D array with initial values,
Each core start read each row of values array, do the counter (or function)
and write it back on own ring,
I wanna do this because I wanna have a separate memory space (here
ring_buffer) allocated for each core,
Wrong answer and I don't know the problem
It would be appreciated if help me,
Regards,

Dear Andriy,
I did my task with the help of rte_ring, but now I wanna replace rte_ring
with real share cache(L3),
May I ask you if there is any possibility in DPDK in order to do it.
Thanks in advance,

[dpdk-dev] [dpdk-users] how to Read(Write) from(to) via lcores in dpdk regardless of NIC

[Mahdi Moradmand Badie]

I wanna create for example 3 different packets in core_0 as master and
store them one by one in share memory(rte_ring),
then the core_1 as slave read them and do function on them (ex. P1+P2+P3)
and again store in share memory, finally the core_0 read the packets from
share memory and compare them with whatever expected :)
As I said and you mentioned is the same? :)

[dpdk-dev] [dpdk-users] how to Read(Write) from(to) via lcores in dpdk regardless of NIC

[Mahdi Moradmand Badie]

Dear Hamed,

First of all thank you so much for your kindly reply,

It's the primary part of the big project, in order to be more familiar with
DPDK,
I have to implement the mentioned framework by use of DPDK,
And finally we wanna implement the cache locking approach (via help of
features like Cache Allocation Technology(CAT), Cache Monitoring Technology
(CMT)) in Xeon processor (my supervisor told me this simple exercise
will be helpful to do the final part) in such a way we could dedicate a
specific part of shared memory (L3) to each core which the other don't
access to it.
Obviously using of DPDK with Xeon which both are from "Intel", is
considered as strength point.

I hope this was more clear :)

[dpdk-dev] how to Read(Write) from(to) via lcores in dpdk regardless of NIC

[Mahdi Moradmand Badie]

Dear All,
I am Mahdi and I am new in DPDK,
I wanna generate for example 3 different packets in core0 as master write
it to share memory (L3), then core1 as slave read this packets, change them
with for example function1 and write again in share memory (L3) and finally
check the result with whatever I expect.
The most important thing is that I don't wanna use NIC and I don't know for
working with cores how I can write/read to/from them, I mean with which
template and sequence???
Thanks in advance,
