1. Set up a project with preempt-rt kernel
./wrlinux-9/setup.sh --dl-layers --kernel preempt-rt --machine bcm-587xx
2. Modify conf/local.conf for perrmpt-rt kernel
KTYPE_ENABLED ?= "preempt-rt"
LINUX_KERNEL_TYPE ?= "preempt-rt"
3. Include cryptsetup package to the project
IMAGE_INSTALL += " cryptsetup"
4. Enable following kernel configs
CONFIG_ARM64_CRYPTO=y
CONFIG_CRYPTO_SHA1_ARM64_CE=y
CONFIG_CRYPTO_SHA2_ARM64_CE=y
CONFIG_CRYPTO_AES_ARM64_CE=y
CONFIG_CRYPTO_AES_ARM64_CE_BLK=y
CONFIG_CRYPTO_USER_API_SKCIPHER
5. Build the project
6. Boot the target
7. Run following command
$ cryptsetup benchmark --debug
8. check the dmesg
I attached the log as warning.log.
