2019-09-13crypto: inside-secure - Probe transform record cache RAM sizesPascal van Leeuwen1-9/+12
This patch actually probes the transform record cache data and administration RAM sizes, instead of making assumptions, and then configures the TRC based on the actually probed values. This allows the driver to work with EIP197 HW that has TRC RAM sizes different from those of the Marvell EIP197B/D variants.

2019-09-13crypto: inside-secure - Base RD fetchcount on actual RD FIFO sizePascal van Leeuwen1-1/+14
This patch derives the result descriptor fetch count from the actual FIFO size advertised by the hardware. Fetching result descriptors one at a time is a performance bottleneck for small blocks, especially on hardware with multiple pipes. Even moreso if the HW has few rings.

2019-09-13crypto: inside-secure - Add EIP97/EIP197 and endianness detectionPascal van Leeuwen1-3/+23
This patch adds automatic EIP97/EIP197 detection, so it does not need to rely on any static value from the device table anymore. In particular, the static value from the table won't work for PCI devboards that cannot be further identified save from this direct hardware probing. The patch also adds automatic host xs endianness detection & correction. Signed-off-by: Pascal van Leeuwen <pvanleeuwen@verimatrix.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2019-09-05crypto: inside-secure - Made .cra_priority value a definePascal van Leeuwen1-0/+3
Instead of having a fixed value (of 300) all over the place, the value for for .cra_priority is now made into a define (SAFEXCEL_CRA_PRIORITY).

2019-09-05crypto: inside-secure - Only enable algorithms advertised by the hardwarePascal van Leeuwen1-0/+33
This patch probes the supported algorithms from the hardware and only registers the ones that the hardware actually supports. This is necessary because this is a generic driver supposed to run on a wide variety of engines, which may or may not implement certain algorithms.

2019-08-30crypto: inside-secure - add support for using the EIP197 without vendor firmwarePascal van Leeuwen1-0/+12
Until now, the inside-secure driver required a set of firmware images supplied by the silicon vendor, typically under NDA, to be present in /lib/firmware/inside-secure in order to be able to function. This patch removes the dependence on this official vendor firmware by falling back to generic "mini" FW - developed specifically for this driver - that can be provided under GPL 2.0 through linux-firmwares.

This patch adds support for a PCIE development board with FPGA from Xilinx, to facilitate pre-silicon driver development by both Inside Secure and its IP customers. Since Inside Secure neither produces nor has access to actual silicon, this is required functionality to allow us to contribute.

2019-08-30crypto: inside-secure - Remove redundant algo to engine mapping codePascal van Leeuwen1-1/+0
This removes some code determine which engine has which algorithms which was effectively redundant (may have been forward-looking?) due to always enabling all algorithms for all currently supported engines. A future patch will use a different, more scalable approach to achieve this. This is removed now because otherwise the next patch will add new hardware which would otherwise have to be added to all algorithms, so now is a convenient time to just get rid of this.

This patch recognises the fact that the hardware cannot ever process more than 2,199,023,386,111 bytes of hash or HMAC payload, so there is no point in maintaining 128 bit wide byte counters, 64 bits is more than sufficient Signed-off-by: Pascal van Leeuwen <pvanleeuwen@verimatrix.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2019-07-26crypto: inside-secure - add support for arbitrary size hash/HMAC updatesPascal van Leeuwen1-1/+3
This patch fixes an issue with hash and HMAC operations that perform "large" intermediate updates (i.e. combined size > 2 hash blocks) by actually making use of the hardware's hash continue capabilities. The original implementation would cache these updates in a buffer that was 2 hash blocks in size and fail if all update calls combined would overflow that buffer. Which caused the cryptomgr extra tests to fail. Signed-off-by: Pascal van Leeuwen <pvanleeuwen@verimatrix.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-07-26crypto: inside-secure - fix EINVAL error (buf overflow) for AEAD decryptPascal van Leeuwen1-1/+1
This patch fixes a buffer overflow error returning -EINVAL for AEAD decrypt operations by NOT appending the (already verified) ICV to the output packet (which is not expected by the API anyway). With this fix, all testmgr AEAD (extra) tests now pass. Signed-off-by: Pascal van Leeuwen <pvanleeuwen@verimatrix.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-06-06crypto: inside-secure - add support for HMAC updatesAntoine Tenart1-1/+1

This patch adds support for retrieving intermediate IV from the crypto engine when using the CBC block mode with AES and (3)DES.

2018-07-08crypto: inside-secure - remove request list to improve performanceOfer Heifetz1-13/+18
This patch main goal is to improve driver performance by moving the crypto request from a list to a RDR ring shadow. This is possible since there is one producer and one consume for this RDR request shadow and one ring descriptor is left unused. Doing this change eliminates the use of spinlock when accessing the descriptor ring and the need to dynamicaly allocate memory per crypto request. The crypto request is placed in the first RDR shadow descriptor only if there are enough descriptors, when the result handler is invoked, it fetches the first result descriptor from RDR shadow.

2018-07-08crypto: inside-secure - set tx_max_cmd_queue to 32Ofer Heifetz1-0/+1
The ORO bridge (connected to the EIP197 write channel) does not generate back pressure towards the EIP197 when its internal FIFO is full. It assumes that the EIP will not drive more write transactions than the maximal supported outstanding (32). Hence tx_max_cmd_queue must be configured to 5 (or less).

Add a flags field in the private structure, and a first flag for engines needing context invalidation (currently only the eip197b).

2018-07-08crypto: inside-secure - filter out the algorithms by engineAntoine Tenart1-2/+3
EIP engines do not support the same set of algorithms. So far the supported engines in the Inside Secure SafeXcel driver support the same set of algorithms, but that won't be true for all engines.

2018-07-08crypto: inside-secure - use precise compatiblesAntoine Tenart1-2/+2
At first we used two compatibles in the SafeXcel driver, named after the engine revision: eip97 and eip197. However this family of engines has more precise versions and in fact we're supporting the eip97ies and eip197b. More versions will be supported in the future, such as the eip197d, and we'll need to differentiate them. This patch fixes the compatibles used in the driver, to now use precise ones. The two historical compatibles are kept for backward compatibility. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
