crypto: ccp - Validate the the error value used to index error messages

2019-07-26T07:12:53Z

commit 52393d617af7b554f03531e6756facf2ea687d2e upstream. The error code read from the queue status register is only 6 bits wide, but we need to verify its value is within range before indexing the error messages.

crypto: ccp - remove duplicate module version and author entry

2017-08-03T05:47:21Z

commit 720419f01832 ("crypto: ccp - Introduce the AMD Secure Processor device") moved the module registeration from ccp-dev.c to sp-dev.c but patch missed removing the module version and author entry from ccp-dev.c. It causes the below warning during boot when CONFIG_CRYPTO_DEV_SP_CCP=y and CONFIG_CRYPTO_DEV_CCP_CRYPTO=y is set. [ 0.187825] sysfs: cannot create duplicate filename '/module/ccp/version' [ 0.187825] sysfs: cannot create duplicate filename '/module/ccp/version' Cc: Tom Lendacky Cc: Gary R Hook Cc: Herbert Xu Cc: David S.

crypto: ccp - Abstract interrupt registeration

2017-07-18T09:57:14Z

The CCP and PSP devices part of AMD Secure Procesor may share the same interrupt. Hence we expand the SP device to register a common interrupt handler and provide functions to CCP and PSP devices to register their interrupt callback which will be invoked upon interrupt.

crypto: ccp - Introduce the AMD Secure Processor device

2017-07-18T09:51:19Z

The CCP device is part of the AMD Secure Processor. In order to expand the usage of the AMD Secure Processor, create a framework that allows functional components of the AMD Secure Processor to be initialized and handled appropriately.

crypto: ccp - Add debugfs entries for CCP information

2017-06-19T06:11:47Z

Expose some data about the configuration and operation of the CCP through debugfs entries: device name, capabilities, configuration, statistics. Allow the user to reset the counters to zero by writing (any value) to the 'stats' file. This can be done per queue or per device.
