crypto: inside-secure - fix clock management

2018-04-08T12:29:50Z

commit f962eb46e7a9b98a58d2483f5eb216e738fec732 upstream. In this driver the clock is got but never put when the driver is removed or if there is an error in the probe. Using the managed version of clk_get() allows to let the kernel take care of it.

crypto: inside-secure - make function safexcel_try_push_requests static

2018-01-25T14:10:28Z

The function safexcel_try_push_requests is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: symbol 'safexcel_try_push_requests' was not declared. Should it be static?

crypto: inside-secure - fix hash when length is a multiple of a block

2018-01-05T07:43:06Z

This patch fixes the hash support in the SafeXcel driver when the update size is a multiple of a block size, and when a final call is made just after with a size of 0. In such cases the driver should cache the last block from the update to avoid handling 0 length data on the final call (that's a hardware limitation).

crypto: inside-secure - avoid unmapping DMA memory that was not mapped

2018-01-05T07:43:05Z

This patch adds a parameter in the SafeXcel ahash request structure to keep track of the number of SG entries mapped. This allows not to call dma_unmap_sg() when dma_map_sg() wasn't called in the first place. This also removes a warning when the debugging of the DMA-API is enabled in the kernel configuration: "DMA-API: device driver tries to free DMA memory it has not allocated".

crypto: inside-secure - EIP97 support

2017-12-22T09:03:36Z

The Inside Secure SafeXcel driver was firstly designed to support the EIP197 cryptographic engine which is an evolution (with much more feature, better performances) of the EIP97 cryptographic engine. This patch convert the Inside Secure SafeXcel driver to support both engines (EIP97 + EIP197). The main differences are the register offsets and the context invalidation process which is EIP197 specific. This patch adds an indirection on the register offsets and adds checks not to send any invalidation request when driving the EIP97. A new compatible is added as well to bind the driver from device trees. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - retry to proceed the request later on fail

2017-12-22T09:03:35Z

The dequeueing function was putting back a request in the crypto queue on failure (when not enough resources are available) which is not perfect as the request will be handled much later. This patch updates this logic by keeping a reference on the failed request to try proceeding it later when enough resources are available. Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - handle more result requests when counter is full

2017-12-22T09:03:35Z

This patch modifies the result handling logic to continue handling results when the completed requests counter is full and not showing the actual number of requests to handle. Suggested-by: Ofer Heifetz Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - acknowledge the result requests all at once

2017-12-22T09:03:34Z

This patches moves the result request acknowledgment from a per request process to acknowledging all the result requests handled at once. Suggested-by: Ofer Heifetz Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - increase the ring size

2017-12-22T09:03:34Z

Increase the ring size to handle more requests in parallel, while keeping the batch size (for interrupt coalescing) to its previous value. The ring size and batch size are now unlinked. Suggested-by: Ofer Heifetz Signed-off-by: Antoine Tenart Signed-off-by: Herbert Xu

crypto: inside-secure - dequeue all requests at once

2017-12-22T09:03:33Z

This patch updates the dequeueing logic to dequeue all requests at once. Since we can have many requests in the queue, the interrupt coalescing is kept so that the ring interrupt fires every EIP197_MAX_BATCH_SZ at most. To allow dequeueing all requests at once while still using reasonable settings for the interrupt coalescing, the result handling function was updated to setup the threshold interrupt when needed (i.e. when more requests than EIP197_MAX_BATCH_SZ are in the queue). When using this capability the ring is marked as busy so that the dequeue function enqueue new requests without setting the threshold interrupt.
