Add `VBOOT_X86_RSA_ACCELERATION' Kconfig option to enable SSE2 instruction set implementation of modulus exponentiation which is part of the RSA signature verification process. This option is enabled on CHROMEOS. | modpow() function call | original on rex0 | SSE2 on rex0 | |------------------------+------------------+--------------| | depthcharge - step 1 | 0.547 | 0.288 | | depthcharge - step 2 | 0.152 | 0.081 | | depthcharge - step 3 | 0.164 | 0.079 | |------------------------+------------------+--------------| | Total (ms) | 0.863 | 0.448 | | modpow() function call | original on brya0 | SSE2 on rex0 | |------------------------+-------------------+--------------| | depthcharge - step 1 | 0.693 | 0.248 | | depthcharge - step 2 | 0.172 | 0.065 | | depthcharge - step 3 | 0.223 | 0.067 | |------------------------+-------------------+--------------| | Total (ms) | 1.088 | 0.38 | BUG=b:312709384 TEST=modular exponentiation is about twice faster on rex0 and brya0 Change-Id: I801ebd7839261c6bd07fb218e1e36a7108e219bf Signed-off-by: Jeremy Compostella <jeremy.compostella@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/79290 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Yu-Ping Wu <yupingso@google.com>
