Hosts the 0x221E linux distro kernel. https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-4.13.y 2017-06-19T06:11:47Z 2017-06-19T06:11:47Z Gary R Hook 2017-05-02T22:33:40Z urn:sha1:3cdbe346ed3f380eae1cb3e9febfe703e7d8a7b0 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. Changes from V1: - Correct polarity of test when destroying devices at module unload Signed-off-by: Gary R Hook <gary.hook@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2017-03-24T14:02:55Z Gary R Hook 2017-03-15T18:21:01Z urn:sha1:36cf515b9bbe298e1ce7384620f0d4ec45ad3328 A version 5 device provides the primitive commands required for AES GCM.

Add support for a version 5 CCP which enables AES/XTS/SHA services. Also, more work on the data structures to virtualize functionality.

Register these services as general purpose DMA channels. Changes since v2: - Add a Signed-off-by Changes since v1: - Allocate memory for a string in ccp_dmaengine_register - Ensure register/unregister calls are properly ordered - Verified all changed files are listed in the diffstat - Undo some superfluous changes - Added a cc: Signed-off-by: Gary R Hook <gary.hook@amd.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> 2016-03-11T13:19:17Z Gary R Hook 2016-03-01T19:49:25Z urn:sha1:ea0375afa17281e9e0190034215d0404dbad7449 Support for different generations of the coprocessor requires that an abstraction layer be implemented for interacting with the hardware. This patch splits out version-specific functions to a separate file and populates the version structure (acting as a driver) with function pointers.
