Subject: [RFC PATCH v1 06/13] crypto: iaa - Disable iaa_verify_compress by default.
Date: Thu, 17 Oct 2024 23:40:54 -0700 [thread overview]
Message-ID: <20241018064101.336232-7-kanchana.p.sridhar@intel.com> (raw)
In-Reply-To: <20241018064101.336232-1-kanchana.p.sridhar@intel.com>
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
