cryptodev driver for t2080

sameerarvikar — Tue, 08 Aug 2017 05:05:12 GMT

I want to generate cryptodev.ko standalone and not with kernel,

so i tried following from sdk document page number --> 1260 (QorIQ SDK v2.0=1703 doc)

• Build cryptodev

$ cd <sdk-dir>/sources/cryptodev
$ make
$ sudo make modules_install
$ sudo install -D crypto/cryptodev.h /usr/include/crypto/cryptodev.h

But there is no makefile at the above place

How to do it for t2080

Hello sameerarvikar,

I assume that you have installed SDK 2.0 Toolchain in /opt/fsl-qoriq/2.0/.

$ source /opt/fsl-qoriq/2.0/environment-setup-ppce6500-fsl-linux

$ unset LDFLAGS
$ make -C /home/b25805/QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb/tmp/work/t2080rdb-fsl-linux/linux-qoriq/4.1-r0/build/ M=/home/b25805/QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb/tmp/work/t2080rdb-fsl-linux/cryptodev-qoriq-module/1.8-r0/cryptodev-linux-1.8 ARCH=powerpc CROSS_COMPILE=powerpc-fsl-linux- modules

The build command

$ make -C <Kernel build directory> M=<cryptodev module source> ARCH=powerpc CROSS_COMPILE=powerpc-fsl-linux- modules

Have a great day,
TIC

Thanks Yiping,

Its working in t2080RDB

Now i got only kernel-source directory for a custom t2080 board

so it doesn't have a build directory as given in the path in above answer

If i use the cryptodev.ko driver generated for t2080 RDB , i got the errors(please find attachment)

How can i generate it with the kernel-source directory

Regards
