I am not able to see .rte_config file

[Eldho Paul Mathew]

EAL: Detected 12 lcore(s)
EAL: Detected 1 NUMA nodes
PANIC in rte_eal_config_attach():
Cannot open '/var/run/.rte_config' for rte_mem_config

I am using DPDK 18.05.1 version.
When I used this DPDK in a VM, I am not able to init the EAL subsystem.
When it is in a Appliances I am able to do.
Question is, who is creating the .rte_config file ?
Is there any specific command required for that.?

Note : Huge Page craetion is successful.

Driver: bnxt_en

[Eldho Paul Mathew]

We are using DPDK 18.05.1

We received a new network card.

Broadcom Inc. and subsidiaries BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet
Controller

DPDK 18.05.1 has support for this card and driver bnxt_en?

If not, which stable version onwards has this driver support added?

Hi All,

What is the importance of the 'ice' driver?

Right now I am using 18.05.1. Does it have 'ice' driver support?

We bought a new card: BCM57508 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb/200Gb
Ethernet

To support this card using the 'ice' driver, is the DPDK 18.05.1 version
sufficient, or is there any other driver that is the placeholder for 'ice'
in 18.05.1?

If I need to go for an upgrade, which is the minimum version to support
this card by 'ice'?

Kindly help!

Migrate DPDK 18.05.1 -> DPDK 24.11.1 LTS

[Eldho Paul Mathew]

Hi,

In the 24.11.1 build, I have specific questions

1) I need the DPDK output in static lib format. How can I switch off the
shared lib build?

2) I need to build librte_kni. a - Is this module deprecated in DPDK 24.11.1

3) How can I enable librte_pmd_* modules? In the driver/net folder, many
pmd are available, but none of them are built in the default ninja build.?
How to enable this?

I used the build steps listed below

cd dpdk
 meson build
 ninja -C build

Will you please help?
