PCLMULQDQ is used to accelerate the most time-consuming part of GHASH, carry-less multiplication. More information about PCLMULQDQ can be found at: http://software.intel.com/en-us/articles/carry-less-multiplication-and-its-usage-for-computing-the-gcm-mode/ Because PCLMULQDQ changes XMM state, its usage must be enclosed with kernel_fpu_begin/end, which can be used only in process context, the acceleration is implemented as crypto_ahash. That is, request in soft IRQ context will be defered to the cryptd kernel thread. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
