* crypto: talitos - Preempt overflow interruptsKim Phillips2008-07-17
| | | | | | | | | | | add requests pending/submit count to prevent request queue full condition by preempting h/w overflow interrupts in software. We do this due to the delay in the delivery and handling of the channel overflow error interrupt.

* crypto: talitos - Use proper form for algorithm driver namesHerbert Xu2008-07-10
| | | | | | | | | | | The name authenc(hmac(sha1-talitos),cbc(aes-talitos)) is potentially ambiguous since it could also mean using the generic authenc template on hmac(sha1-talitos) and cbc(aes-talitos).

Note 1: also fix a harmless typo while moving it: sa_idx is initialized to dma->resi instead of dma->cmdi.

| | | | | | | | | | | | | When the CryptoAPI instantiates a new algorithm, it performs a lookup by driver name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current PLL initalization has a number of deficiencies: - uses fixed multiplier of 8, which overclocks the chip when using a reference clock that operates at frequencies above 33MHz. According to a comment in the BSD source, this is true for the external clock on almost all every board. - writes to a reserved bit - doesn't follow the initialization procedure specified in chapter 6.11.1 of the HIFN hardware users guide - doesn't allow to use the PCI clock This patch adds a module parameter to specify the reference clock (pci or external) and its frequency and uses that to calculate the optimum multiplier to reach the maximal speed. By default it uses the external clock and assumes a speed of 66MHz, which effectively halfs the frequency currently used.

| * [CRYPTO] ablkcipher: Add distinct ABLKCIPHER typeHerbert Xu2008-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now we have ablkcipher algorithms have been identified as type BLKCIPHER with the ASYNC bit set. This is suboptimal because ablkcipher refers to two things. On the one hand it refers to the top-level ablkcipher interface with requests. On the other hand it refers to and algorithm type underneath. As it is you cannot request a synchronous block cipher algorithm with the ablkcipher interface on top. This is a problem because we want to be able to eventually phase out the blkcipher top-level interface. This patch fixes this by making ABLKCIPHER its own type, just as we have distinct types for HASH and DIGEST. The type it associated with the algorithm implementation only. Which top-level interface is used for synchronous block ciphers is then determined by the mask that's used. If it's a specific mask then the old blkcipher interface is given, otherwise we go with the new ablkcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| * [CRYPTO] geode: relax in busy loop and care about return valueSebastian Siewior2008-01-10
| | | | | | | | | | | | | | | | | | | | | | The code waits in a busy loop until the hardware finishes the encryption or decryption process. This wants a cpu_relax() :) The busy loop finishes either if the encryption is done or if the counter is zero. If the latter is true than the hardware failed. Since this should not happen, leave sith a BUG(). Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
