2015-12-23crypto: atmel-aes - add debug facilities to monitor register accesses.Cyrille Pitchen1-1/+114
This feature should not be enabled in release but can be usefull for developers who need to monitor register accesses at some specific places. Set the AES_FLAGS_DUMP_REG flag inside dd->flags to start monitoring the I/O accesses, clear it to stop monitoring.

Increase the DMA threshold to 256: PIO accesses offer better performances than the DMA when processing small amounts of data. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-12-23crypto: atmel-aes - fix the counter overflow in CTR modeCyrille Pitchen1-2/+115
Depending on its hardware version, the AES IP provides either a 16 or a 32 bit counter. However the CTR mode expects the size of the counter to be the same as the size of the cipher block, ie 128 bits for AES. This patch detects and handles counter overflows.

2015-12-23crypto: atmel-aes - create sections to regroup functions by usageCyrille Pitchen1-102/+108
This patch only creates sections to regroup functions by usage. This will help to integrate the GCM support patch later by making the difference between shared/common and specific code. Hence current sections are: - Shared functions: common code which will be reused by the GCM support. - CPU transfer: handles transfers monitored by the CPU (PIO accesses). - DMA transfer: handles transfers monitored by the DMA controller. - AES async block ciphers: dedicated to the already supported block ciphers - Probe functions: used to register all crypto algorithms.

2015-12-23crypto: atmel-aes - improve performances of data transferCyrille Pitchen1-378/+386
This patch totally reworks data transfer. 1 - DMA The new code now fully supports scatter-gather lists hence reducing the number of interrupts in some cases. Also buffer alignments are better managed to avoid useless copies. 2 - CPU The new code allows to use PIO accesses even when transferring more than one AES block, so futher patches could tune the DMA threshold (ATMEL_AES_DMA_THRESHOLD). Moreover, CPU transfers now have a chance to be processed synchronously, hence reducing the latency by avoiding context switches when possible (less interrupts to process, less scheduling of the 'done' task). Indeed the 'DATA READY' bit is polled only one time in the Interrupt Status Register before enabling then waiting for the associated interrupt. In some condition, this single poll is enough as the data have already been processed by the AES hardware and so are ready.

2015-12-23crypto: atmel-aes - remove useless AES_FLAGS_DMA flagCyrille Pitchen1-22/+15
Since the 'done' task code was split into atmel_aes_cpu_complete() and atmel_aes_dma_complete(), the AES_FLAGS_DMA flag has become useless. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-12-23crypto: atmel-aes - reduce latency of DMA completionCyrille Pitchen1-2/+2
atmel_aes_dma_callback() now directly calls the 'resume' callback instead of scheduling the done task, which in turn only calls the very same 'resume' callback. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-12-23crypto: atmel-aes - rework crypto request completionCyrille Pitchen1-27/+47
This patch introduces a new callback 'resume' in the struct atmel_aes_dev. This callback is run to resume/complete the processing of the crypto request when woken up by I/O events such as AES interrupts or DMA completion. This callback will help implementing the GCM mode support in further patches. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-12-23crypto: atmel-aes - make crypto request queue management more genericCyrille Pitchen1-26/+49
This patch changes atmel_aes_handle_queue() to make it more generic. The function argument is now a pointer to struct crypto_async_request, which is the common base of struct ablkcipher_request and struct aead_request. Also this patch introduces struct atmel_aes_base_ctx which will be the common base of all the transformation contexts. Hence the very same queue will be used to manage both block cipher and AEAD requests (such as gcm and authenc implemented in further patches).

2015-12-23crypto: atmel-aes - change atmel_aes_write_ctrl() signatureCyrille Pitchen1-14/+10
This patch changes the signature of atmel_aes_write_ctrl() to make it more generic. This will be used by future patches when implementing new block cipher modes such as GCM. Especially atmel_aes_hw_init() is now called outside atmel_aes_write_ctrl(): this allows to call atmel_aes_write_ctrl() many times, still initializing the hardware only once. Indeed, the support of GCM will require to update the Mode Register and the IV when processing a single request.

2015-12-23crypto: atmel-aes - propagate error from atmel_aes_hw_version_init()Cyrille Pitchen1-5/+11

2015-12-11crypto: qat - ring returning retry even though ring has BWHarvijay Saini1-3/+2
When many threads submit multiple requests they get blocked until all responses are processed, which prevents them from submitting more requests even though there is space on the rings. To fix this we need to decrement the inflight counter early to in the callback.

2015-12-10crypto: sahara - fix debug output for 64-bit dma_addr_tArnd Bergmann1-4/+4
The sahara_dump_descriptors and sahara_dump_links functions attempt to print a dma_addr_t value with a 0x%08x format string, which produces a warning when dma_addr_t is 64-bit wide: drivers/crypto/sahara.c:419:120: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] This changes the code to use the %pad format string that is meant for dma_addr_t, which avoids the warning and gives us the correct output in all configurations.

2015-12-10crypto: sahara - fix 64-bit dma_addr_t compilationArnd Bergmann1-9/+9
The sahara hardware uses DMA descriptors with 32-bit addresses, but dma_addr_t is variable size depending on whether we want to support any devices that use 64-bit DMA addresses in hardware. This means that the definition of the DMA descriptor structure is wrong, and we helpfully get a compiler warning about them too: drivers/crypto/sahara.c:423:372: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] This changes the definition of the sahara_hw_desc and sahara_hw_link structures to only contain fixed-length members, which is required to make the driver work on ARM LPAE mode, and avoids most of the gcc warnings we get.
