The SPAcc supports multiple ciphers, hashes and AEAD algorithms with various modes. The driver currently supports below hash: - cmac(aes) - xcbc(aes) - cmac(sm4) - xcbc(sm4) - hmac(md5) - md5 - hmac(sha1) - sha1 - sha224 - sha256 - sha384 - sha512 - hmac(sha224) - hmac(sha256) - hmac(sha384) - hmac(sha512) - sha3-224 - sha3-256 - sha3-384 - sha3-512 - hmac(sm3) - sm3 - michael_mic changelog: v1->v2 changes: - Added local_bh_disable() and local_bh_enable() for the below calls. a. for ciphers skcipher_request_complete() b. for aead aead_request_complete() c. for hash ahash_request_complete() - dt-bindings updates a. removed snps,vspacc-priority and made it into config option b. renamed snps,spacc-wdtimer to snps,spacc-internal-counter c. Added description to all properties - Updated corresponding dt-binding changes to code v2->v3 changes: - cra_init and cra_exit replaced with init_tfm and exit_tfm for hashes. - removed mutex_lock/unlock for spacc_skcipher_fallback call - dt-bindings updates a. updated SOC related information b. renamed compatible string as per SOC - Updated corresponding dt-binding changes to code v3->v4 changes: - removed snps,vspacc-id from the dt-bindings - removed mutex_lock from ciphers - replaced magic numbers with macros - removed sw_fb variable from struct mode_tab and associated code from the hashes - polling code is replaced by wait_event_interruptible v4->v5 changes: - Updated to register with the crypto-engine - Used semaphore to manage SPAcc device hardware context pool - This patchset supports Hashes only - Dropping the support for Ciphers and AEADs in this patchset - Added Reviewed-by tag on the Device tree patch since it was reviewed on v4 patch by Krzysztof Kozlowski and Rob Herring (Arm) v5->v6 changes: - Removed CRYPTO_DEV_SPACC_CIPHER and CRYPTO_DEV_SPACC_AEAD Kconfig options, since the cipher and aead support is not part of this patchset - Dropped spacc_skcipher.o and spacc_aead.o from Makefile to fix build errors reported by kernel test robot - Added Reported-by and Closes tags as suggested v6->v7 changes: - Fixed build error reported by Kernel test robot - Added Reported-by and Closes tags as suggested v7->v8 changes: - Fixed misleading comment: Clarified that only HMAC key pre-processing is done in software, while the actual HMAC operation is performed by hardware - Simplified do_shash() function signature by removing unused parameters - Updated all do_shash() call sites to use new simplified signature - Fixed commit message formatting by adding "crypto: spacc - " to all patches - used __free() for scope based resource management v8->v9 changes: - Updated the software fallback implementation to use HASH_FBREQ_ON_STACK - Corrected dynamic allocation of statesize and reqsize in init_tfm - Fixed synchronization issues in the digest request v9->v10 changes: - Fixed unused variable warning v10->v11 changes: - Removed the redundant crypto_alloc_ahash in the init_tfm function - Removed the redundant crypto_free_ahash in exit_tfm function - Removed the redundant crypto_ahash_setkey call in setkey function v11->v12 changes: - Removed do_shash() and switched to lib/crypto API in spacc_hash_setkey - Dropped support for SM3 algorithm - Improved multi-device safety by encapsulating handling within priv - Added memzero_explicit() in sensitive paths - Minor code cleanups and style fixes - Algorithm registration cleanups Pavitrakumar Managutte (4): dt-bindings: crypto: Document support for SPAcc crypto: spacc - Add SPAcc ahash support crypto: spacc - Add SPAcc AUTODETECT Support crypto: spacc - Add SPAcc Kconfig and Makefile .../bindings/crypto/snps,dwc-spacc.yaml | 50 + drivers/crypto/Kconfig | 1 + drivers/crypto/Makefile | 1 + drivers/crypto/dwc-spacc/Kconfig | 88 + drivers/crypto/dwc-spacc/Makefile | 8 + drivers/crypto/dwc-spacc/spacc_ahash.c | 821 ++++++ drivers/crypto/dwc-spacc/spacc_core.c | 2413 +++++++++++++++++ drivers/crypto/dwc-spacc/spacc_core.h | 838 ++++++ drivers/crypto/dwc-spacc/spacc_device.c | 275 ++ drivers/crypto/dwc-spacc/spacc_device.h | 236 ++ drivers/crypto/dwc-spacc/spacc_hal.c | 374 +++ drivers/crypto/dwc-spacc/spacc_hal.h | 114 + drivers/crypto/dwc-spacc/spacc_interrupt.c | 328 +++ drivers/crypto/dwc-spacc/spacc_manager.c | 610 +++++ 14 files changed, 6157 insertions(+) create mode 100644 Documentation/devicetree/bindings/crypto/snps,dwc-spacc.yaml create mode 100644 drivers/crypto/dwc-spacc/Kconfig create mode 100644 drivers/crypto/dwc-spacc/Makefile create mode 100644 drivers/crypto/dwc-spacc/spacc_ahash.c create mode 100644 drivers/crypto/dwc-spacc/spacc_core.c create mode 100644 drivers/crypto/dwc-spacc/spacc_core.h create mode 100644 drivers/crypto/dwc-spacc/spacc_device.c create mode 100644 drivers/crypto/dwc-spacc/spacc_device.h create mode 100644 drivers/crypto/dwc-spacc/spacc_hal.c create mode 100644 drivers/crypto/dwc-spacc/spacc_hal.h create mode 100644 drivers/crypto/dwc-spacc/spacc_interrupt.c create mode 100644 drivers/crypto/dwc-spacc/spacc_manager.c base-commit: 8879a3c110cb8ca5a69c937643f226697aa551d9 -- 2.25.1
