2026-01-15lib/crypto: sparc/aes: Migrate optimized code into libraryEric Biggers
Move the SPARC64 AES assembly code into lib/crypto/, wire the key expansion and single-block en/decryption functions up to the AES library API, and remove the "aes-sparc64" crypto_cipher algorithm. The result is that both the AES library and crypto_cipher APIs use the SPARC64 AES opcodes, whereas previously only crypto_cipher did (and it wasn't enabled by default, which this commit fixes as well). Note that some of the functions in the SPARC64 AES assembly code are still used by the AES mode implementations in arch/sparc/crypto/aes_glue.c. For now, just export these functions. These exports will go away once the AES mode implementations are migrated to the library as well. (Trying to split up the assembly file seemed like much more trouble than it would be worth.)

2025-08-26lib/crypto: sparc/md5: Migrate optimized code into libraryEric Biggers
Instead of exposing the sparc-optimized MD5 code via sparc-specific crypto_shash algorithms, instead just implement the md5_blocks() library function. This is much simpler, it makes the MD5 library functions be sparc-optimized, and it fixes the longstanding issue where the sparc-optimized MD5 code was disabled by default. MD5 still remains available through crypto_shash, but individual architectures no longer need to handle it. Note: to see the diff from arch/sparc/crypto/md5_glue.c to lib/crypto/sparc/md5.h, view this commit with 'git show -M10'.

2025-07-14lib/crypto: sparc/sha1: Migrate optimized code into libraryEric Biggers
Instead of exposing the sparc-optimized SHA-1 code via sparc-specific crypto_shash algorithms, instead just implement the sha1_blocks() library function. This is much simpler, it makes the SHA-1 library functions be sparc-optimized, and it fixes the longstanding issue where the sparc-optimized SHA-1 code was disabled by default. SHA-1 still remains available through crypto_shash, but individual architectures no longer need to handle it.

2025-06-30lib/crypto: sparc/sha512: Migrate optimized SHA-512 code to libraryEric Biggers
Instead of exposing the sparc-optimized SHA-512 code via sparc-specific crypto_shash algorithms, instead just implement the sha512_blocks() library function. This is much simpler, it makes the SHA-512 (and SHA-384) library functions be sparc-optimized, and it fixes the longstanding issue where the sparc-optimized SHA-512 code was disabled by default. SHA-512 still remains available through crypto_shash, but individual architectures no longer need to handle it. To match sha512_blocks(), change the type of the nblocks parameter of the assembly function from int to size_t. The assembly function actually already treated it as size_t.

2025-05-05crypto: sparc/sha256 - implement library instead of shashEric Biggers
Instead of providing crypto_shash algorithms for the arch-optimized SHA-256 code, instead implement the SHA-256 library. This is much simpler, it makes the SHA-256 library functions be arch-optimized, and it fixes the longstanding issue where the arch-optimized SHA-256 was disabled by default.

2024-12-01sparc/crc32: expose CRC32 functions through libEric Biggers
Move the sparc CRC32C assembly code into the lib directory and wire it up to the library interface. This allows it to be used without going through the crypto API. It remains usable via the crypto API too via the shash algorithms that use the library interface. Thus all the arch-specific "shash" code becomes unnecessary and is removed.
