[PATCH v6 0/3] Add Support for Cavium Cryptographic Acceleration Unit

From: George Cherian
Date: Tue Feb 07 2017 - 09:51:47 EST


This series adds the support for Cavium Cryptographic Accelerarion Unit (CPT)
CPT is available in Cavium's Octeon-Tx SoC series.

The series was tested with ecryptfs and dm-crypt for in kernel cryptographic
offload operations. This driver needs a firmware to work, I will be sending the
firmware to linux-firmware once the driver is accepted.

Cahnges v5 -> v6
-- Addressed Sasha Levin's comments.
- Remove open coding of hlist_for_each_entry_safe, instead use
the same.
- Remove the direct access of hlist members
- Remove unwanted argument checks.
Changes v4 -> v5
--Addressed Stephan Muller's comments.
- Fix XTS key sizes.
- Introduce a new fuction for xts setkey.
- There was a key2 misalignment issue, the same is also fixed
for aes_xts.
Changes v3 -> v4
--Addressed Corentin Labbe's comments
- Convert all pr_x to dev_x.
- Fix Typo errors.
- Fix the Double unlock.
- Use sg_virt.
Changes v2 -> v3
-- Addressed David Daney's comments
- There is not much difference in performance readq/writeq vs
readq_relaxed/writeq_relaxed, so switching to readq/writeq variant.
- Removed the useless bitfield definitions.
- Use GENMASK,dev_to_node() instead of custome functions.
- Use module_pci_driver instead of module_init/exit.
Changes v1 -> v2
-- Addressed a crash issue when more gather components are passed.
-- Redo the cptvf request manager.
- Get rid of the un necessary buffer copies.
-- s/uint*_t/u*
-- Remove unwanted Macro definitions
-- Remove the redundant ROUNDUP* macros and use kernel function
-- Select proper config option in Kconfig file.
-- Removed some of the unwanted header file inclusions
-- Miscellaneous Cleanup
