In its current form, we cannot test multiple simultaneous crypto sessions with tcrypt. Crypto offload hardware accelerators are usually capable of handling multiple session in parallel. This patch allows to load such hardware. Even if offload accelerators are not present, multiple crypto sessions can execute in parallel on Multicore. > Does not this change make tcrypt give > inconsistent results? > Based on kernel scheduling of threads, this change can make tcrypt give varying results in different runs. For consistent results, we can use existing synchronous mode crypto sessions. -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
