When enable_single_wr is not enabled, the DSE will only write those parts of a result descriptor that need updating, which means a final result descriptor will be written in 2 or 3 smaller transfers. When enable_single_wr is enabled the DSE will combine these 2-3 updates into one large write transfer, generally improving performance. Signed-off-by:

Set the correct value to the DSE data cache, using WR_CACHE_3BITS instead of RD_CACHE_3BITS. This fixes an incorrect setting and helps improving performances. Reported-by:

The EIP197_HIA_xDR_CFG_WR_CACHE macro was defined to use an offset of 23, which is wrong as it's actually 25. Fix this. Reported-by:

The PKCS#1 RSA implementation is provided with a self test with RSA 2048 and SHA-256. This self test implicitly covers other RSA keys and other hashes. Also, this self test implies that the pkcs1pad(rsa) is FIPS 140-2 compliant. Signed-off-by:

The run-time self-tests fail quite early, as soon as the input block size is larger than 64 bytes: alg: hash: Test 4 failed for sha1-sun4i-ss 00000000: b9 c9 1e 52 c0 26 d8 39 81 ff f2 3c 99 b1 27 b2 00000010: 30 d6 c9 85 One thing to notice is the value of the last word, which is the one expected (it can sometime be the last two words). The datasheet isn't very clear about when the digest is ready to retrieve and is seems the bit SS_DATA_END is cleared when the digest was computed *but* that doesn't mean the digest is ready to retrieve in the registers. A ndelay(1) is added before reading the computed digest to ensure it is available in the SS_MD[] registers. Signed-off-by:

The CRYPTO_ALG_KERN_DRIVER_ONLY flag is set for hardware accelerated ciphers accessible through a kernel driver only. This is the case for ciphers exposed by the sun4i-ss driver. This patch sets this flag. Signed-off-by:

Antoine Ténart authored
Update the sun4i-ss driver to use the skcipher API instead of the old ablkcipher one. It's a bit more tricky than s/ablkcipher/skcipher/, but still nothing special and the driver's logic stays the same. Signed-off-by:

- Fixed bugs in example for shash and rng (added missing "*" and " *"). - Corrected pr_info() in calc_hash(). - Added example usage of calc_hash(). - No need for negate PTR_ERR to get error code, as crypto_alloc_rng already returns negative values like ERR_PTR(-ENOMEM). Fixed. Signed-off-by:
