This patch makes it easier for IAA hardware acceleration in the iaa_crypto driver to be loaded by default with "iaa_verify_compress" disabled, to facilitate performance comparisons with software compressors (which also do not run compress verification by default). 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 <kanchana.p.sridhar@intel.com> --- drivers/crypto/intel/iaa/iaa_crypto_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
