[ACC] [PATCH 0/6] uadk: update ecc/rsa/dh function
To simplify the calling logic of uadk, a new init2 interface is added to the ecc/rsa/dh algorithm class, which includes hardware device resource initialization and scheduler initialization. Weili Qian (6): uadk/ecc: add the init2 interface for ecc uadk/rsa: add the init2 interface for rsa uadk/dh: add the init2 interface for dh uadk/ecc: adapt the ecc module to the dynamic loading framework uadk/rsa: adapt the rsa module to the dynamic loading framework uadk/dh: adapt the dh module to the dynamic loading framework drv/hisi_hpre.c | 180 +++++++++++++++++++-------- include/drv/wd_dh_drv.h | 27 ---- include/drv/wd_ecc_drv.h | 27 ---- include/drv/wd_rsa_drv.h | 27 ---- include/wd_dh.h | 30 +++++ include/wd_ecc.h | 28 +++++ include/wd_rsa.h | 28 +++++ libwd_crypto.map | 9 ++ wd_dh.c | 256 +++++++++++++++++++++++++++----------- wd_ecc.c | 262 ++++++++++++++++++++++++++++----------- wd_rsa.c | 256 +++++++++++++++++++++++++++----------- 11 files changed, 786 insertions(+), 344 deletions(-) -- 2.33.0
