crypto: caam - enable crypto-engine retry mechanism

2020-11-06T03:29:11Z

Use the new crypto_engine_alloc_init_and_set() function to initialize crypto-engine and enable retry mechanism. Set the maximum size for crypto-engine software queue based on Job Ring size (JOBR_DEPTH) and a threshold (reserved for the non-crypto-API requests that are not passed through crypto-engine). The callback for do_batch_requests is NULL, since CAAM doesn't support linked requests. Signed-off-by: Iuliana Prodan Reviewed-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: caam - Move debugfs fops into standalone file

2020-08-21T04:47:49Z

Currently the debugfs fops are defined in caam/intern.h. This causes problems because it creates identical static functions and variables in multiple files. It also creates warnings when those files don't use the fops. This patch moves them into a standalone file, debugfs.c. It also removes unnecessary uses of ifdefs on CONFIG_DEBUG_FS.

crypto: caam - drop global context pointer and init_done

2020-03-30T00:50:49Z

Leverage devres to get rid of code storing global context as well as init_done flag. Original code also has a circular deallocation dependency where unregister_algs() -> caam_rng_exit() -> caam_jr_free() chain would only happen if all of JRs were freed. Fix this by moving caam_rng_exit() outside of unregister_algs() and doing it specifically for JR that instantiated HWRNG.

crypto: caam - support crypto_engine framework for SKCIPHER algorithms

2020-02-22T01:25:47Z

Integrate crypto_engine into CAAM, to make use of the engine queue. Add support for SKCIPHER algorithms. This is intended to be used for CAAM backlogging support. The requests, with backlog flag (e.g. from dm-crypt) will be listed into crypto-engine queue and processed by CAAM when free. This changes the return codes for enqueuing a request: -EINPROGRESS if OK, -EBUSY if request is backlogged (via crypto-engine), -ENOSPC if the queue is full, -EIO if it cannot map the caller's descriptor. The requests, with backlog flag, will be listed into crypto-engine queue and processed by CAAM when free. Only the backlog request are sent to crypto-engine since the others can be handled by CAAM, if free, especially since JR has up to 1024 entries (more than the 10 entries from crypto-engine).

crypto: caam - select DMA address size at runtime

2019-08-30T08:05:30Z

i.MX8 mScale SoC still use 32-bit addresses in its CAAM implmentation, so we can't rely on sizeof(dma_addr_t) to detemine CAAM pointer size. Convert the code to query CTPR and MCFGR for that during driver probing.

crypto: caam - don't hardcode inpentry size

2019-08-30T08:05:30Z

Using dma_addr_t for elements of JobR input ring is not appropriate on all 64-bit SoCs, some of which, like i.MX8MQ, use only 32-bit wide pointers there. Convert all of the code to use explicit helper function that can be later extended to support i.MX8MQ. No functional change intended.

crypto: caam - drop explicit usage of struct jr_outentry

2019-08-30T08:05:30Z

Using struct jr_outentry to specify the layout of JobR output ring is not appropriate for all 64-bit SoC, since some of them, like i.MX8MQ, use 32-bit pointers there which doesn't match 64-bit dma_addr_t. Convert existing code to use explicit helper functions to access any of the JobR output ring elements, so that the support for i.MX8MQ can be added later. No functional change intended.
