Earlier, the "sync" mode used to be the default. This way, anyone that wants to use IAA can do so after building the kernel, and without having to go through these steps to use async poll: 1) disable all the IAA device/wq bindings that happen at boot time 2) rmmod iaa_crypto 3) modprobe iaa_crypto 4) echo async > /sys/bus/dsa/drivers/crypto/sync_mode 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 3ac3a37fd2e6..13f9d22811ff 100644 --- a/drivers/crypto/intel/iaa/iaa_crypto_main.c +++ b/drivers/crypto/intel/iaa/iaa_crypto_main.c @@ -153,7 +153,7 @@ static DRIVER_ATTR_RW(verify_compress); */ /* Use async mode */ -static bool async_mode; +static bool async_mode = true; /* Use interrupts */ static bool use_irq;
