2013-08-21crypto: omap-aes - PIO mode: Add IRQ handler and walk SGsJoel Fernandes1-0/+90
We add an IRQ handler that implements a state-machine for PIO-mode and data structures for walking the scatter-gather list. The IRQ handler is called in succession both when data is available to read or next data can be sent for processing. This process continues till the entire in/out SG lists have been walked. Once the SG-list has been completely walked, the IRQ handler schedules the done_task tasklet. Also add a useful macro that is used through out the IRQ code for a common pattern of calculating how much an SG list has been walked. This improves code readability and avoids checkpatch errors.

2013-08-21crypto: omap-aes - Remove previously used intermediate buffersJoel Fernandes1-90/+0
Intermdiate buffers were allocated, mapped and used for DMA. These are no longer required as we use the SGs from crypto layer directly in previous commits in the series. Also along with it, remove the logic for copying SGs etc as they are no longer used, and all the associated variables in omap_aes_device.

2013-08-21crypto: omap-aes - Simplify DMA usage by using direct SGsJoel Fernandes1-122/+25
In early version of this driver, assumptions were made such as DMA layer requires contiguous buffers etc. Due to this, new buffers were allocated, mapped and used for DMA. These assumptions are no longer true and DMAEngine scatter-gather DMA doesn't have such requirements. We simply the DMA operations by directly using the scatter-gather buffers provided by the crypto layer instead of creating our own. Lot of logic that handled DMA'ing only X number of bytes of the total, or as much as fitted into a 3rd party buffer is removed and is no longer required. Also, good performance improvement of atleast ~20% seen with encrypting a buffer size of 8K (1800 ops/sec vs 1400 ops/sec). Improvement will be higher for much larger blocks though such benchmarking is left as an exercise for the reader. Also DMA usage is much more simplified and coherent with rest of the code.

2013-08-21crypto: omap-aes - Populate number of SG elementsJoel Fernandes1-0/+6
Crypto layer only passes nbytes but number of SG elements is needed for mapping or unmapping SGs at one time using dma_map* API and also needed to pass in for dmaengine prep function. We call function added to scatterwalk for this purpose in omap_aes_handle_queue to populate the values which are used later.

2013-08-14crypto: nx - fix concurrency issueMarcelo Cerri10-12/+87
The NX driver uses the transformation context to store several fields containing data related to the state of the operations in progress. Since a single tfm can be used by different kernel threads at the same time, we need to protect the data stored into the context. This patch makes use of spin locks to protect the data where a race condition can happen.

2013-08-09crypto: nx - fix limits to sg lists for SHA-2Marcelo Cerri2-95/+132
The co-processor has several limits regarding the length of scatter/gather lists and the total number of bytes in it. These limits are available in the device tree, as following: - "ibm,max-sg-len": maximum number of bytes of each scatter/gather list. - "ibm,max-sync-cop": used for synchronous operations, it is an array of structures that contains information regarding the limits that must be considered for each mode and operation. The most important limits in it are: - The total number of bytes that a scatter/gather list can hold. - The maximum number of elements that a scatter/gather list can have. This patch updates the NX driver to perform several hyper calls if needed in order to always respect the length limits for scatter/gather lists.

The co-processor receives data to be hashed through scatter/gather lists pointing to physical addresses. When a vmalloc'ed data is given, the driver must calculate the physical address to each page of the data. However the current version of it just calculates the physical address once and keeps incrementing it even when a page boundary is crossed. This patch fixes this behaviour.

2013-06-05crypto: omap-aes - Don't idle/start AES device between Encrypt operationsJoel A Fernandes1-10/+19
Calling runtime PM API for every block causes serious perf hit to crypto operations that are done on a long buffer. As crypto is performed on a page boundary, encrypting large buffers can cause a series of crypto operations divided by page. The runtime PM API is also called those many times. We call runtime_pm_get_sync only at beginning on the session (cra_init) and runtime_pm_put at the end. This result in upto a 50% speedup as below. This doesn't make the driver to keep the system awake as runtime get/put is only called during a crypto session which completes usually quickly.
