Subject: [dpdk-users] Create new driver error
Date: Wed, 30 Jan 2019 11:42:04 +0100	[thread overview]
Message-ID: <CAPwfg=aGdy9WpzuwFg4ghRZ7DvCc-yTn20A+uu6jJPXN3GRtmA@mail.gmail.com> (raw)

Hello!

I´m trying to create a new driver called "baseband_ldpc" for baseband but I
get this error:

EAL: failed to parse device "baseband_ldpc"
EAL: Unable to parse device 'baseband_ldpc'


I created the driver in the /dpdk/drivers/baseband/ldpc folder.
The file is called ldpc.c
I created a copy of the Makefile from the other drivers but changed these
lines:

LIB =librte_pmd_bbdev_ldpc.a
...
EXPORT_MAP :=rte_pmd_bbdev_ldpc_version.map
...
SRCS-$(CONFIG_RTELIBRTE_PMD_BBDEV_LDPC) += ldpc.c


I added this line in the Makefile in the folder /dpdk/drivers/baseband
DIRS-$(CONFIG_RTE_LIBRTE_PMD_BBDEV_LDPC) += ldpc
DEPDIRS-ldpc = $(core-libs)

I also added these lines in the common_base file:
CONFIG_RTE_LIBRTE_PMD_BBDEV_LDPC=y

My guess is that the error has something to do with vdev and that my
baseband_ldpc doesnt get registered as a valid vdev.

My command for running the app is:
./build/bbdev --vdev='baseband_ldpc' --vdev='net_tap0' --no-pci

I hope that you can help with this problem.

Best regards,
Oscar
