Earlier, iaa_crypto compress verification used to be enabled by default. With this patch, if users want to enable compress verification, they can do so with these steps: 1) disable all the IAA device/wq bindings that happen at boot time 2) rmmod iaa_crypto 3) modprobe iaa_crypto 4) echo 1 > /sys/bus/dsa/drivers/crypto/verify_compress 5) re-run initialization of the IAA devices and wqs Signed-off-by: Kanchana P Sridhar --- drivers/crypto/intel/iaa/iaa_crypto_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/crypto/intel/iaa/iaa_crypto_main.c b/drivers/crypto/intel/iaa/iaa_crypto_main.c index 6c262b1eb09d..8e6859c97970 100644 --- a/drivers/crypto/intel/iaa/iaa_crypto_main.c +++ b/drivers/crypto/intel/iaa/iaa_crypto_main.c @@ -94,7 +94,7 @@ static bool iaa_crypto_enabled; static bool iaa_crypto_registered; /* Verify results of IAA compress or not */ -static bool iaa_verify_compress = true; +static bool iaa_verify_compress = false; static ssize_t verify_compress_show(struct device_driver *driver, char *buf) {
