It can be changed by 737 setting the aes_sw_max_len parameter. 738 739 Small blocks are processed faster in software than hardware. 740 Considering the 256-bit ciphers, software is 2-3 times faster than 741 qce at 256-bytes, 30% faster at 512, and about even at 768-bytes. 742 With 128-bit keys, the break-even point would be around 1024-bytes. 743 744 The default is set a little lower, to 512 bytes, to balance the 745 cost in CPU usage. The minimum recommended setting is 16-bytes 746 (1 AES block), since AES-GCM will fail if you set it lower. 747 Setting this to zero will send all requests to the hardware. 748 749 Note that 192-bit keys are not supported by the hardware and are 750 always processed by the software fallback, and all DES requests 751 are done by the hardware. 752 753config CRYPTO_DEV_QCOM_RNG 754 tristate "Qualcomm Random Number Generator Driver" 755 depends on ARCH_QCOM || COMPILE_TEST 756 select CRYPTO_RNG 757 help 758 This driver provides support for the Random Number 759 Generator hardware found on Qualcomm SoCs. 760 761 To compile this driver as a module, choose M here.
