Earlier, the "sync" mode used to be the default. This way, anyone who wants to use IAA for zswap/zram can do so after building the kernel, and without having to go through these steps to use async request chaining: 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 b51b0b4b9ac3..6d49f82165fe 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;
