+ ima.ahash_minsize= [IMA] Minimum file size for asynchronous hash usage
+ Format: <min_file_size>
+ Set the minimal file size for using asynchronous hash.
+ If left unspecified, ahash usage is disabled.
+
+ ahash performance varies for different data sizes on
+ different crypto accelerators. This option can be used
+ to achieve the best performance for a particular HW.
+
+ ima.ahash_bufsize= [IMA] Asynchronous hash buffer size
+ Format: <bufsize>
+ Set hashing buffer size. Default: 4k.
+
+ ahash performance varies for different chunk sizes on
+ different crypto accelerators. This option can be used
+ to achieve best performance for particular HW.
