6 Enables the driver module for Freescale's Cryptographic Accelerator
7 and Assurance Module (CAAM), also known as the SEC version 4 (SEC4).
8 This module creates job ring devices, and configures h/w
9 to operate as a DPAA component automatically, depending
10 on h/w feature availability.
11
12 To compile this driver as a module, choose M here: the module
13 will be called caam.

20 Enables the driver module for Job Rings which are part of
21 Freescale's Cryptographic Accelerator
22 and Assurance Module (CAAM). This module adds a job ring operation
23 interface.

25 To compile this driver as a module, choose M here: the module
26 will be called caam_jr.

33 help
34 Select size of Job Rings as a power of 2, within the
35 range 2-9 (ring size 4-512).
36 Examples:
37 2 => 4
38 3 => 8
39 4 => 16
40 5 => 32
41 6 => 64

47 bool "Job Ring interrupt coalescing"
48 depends on CRYPTO_DEV_FSL_CAAM_JR
49 help
50 Enable the Job Ring's interrupt coalescing feature.
51
52 Note: the driver already provides adequate
53 interrupt coalescing in software.

58 range 1 255
59 default 255
60 help
61 Select number of descriptor completions to queue before
62 raising an interrupt, in the range 1-255. Note that a selection
63 of 1 functionally defeats the coalescing feature, and a selection
64 equal or greater than the job ring size will force timeouts.

71 help
72 Select number of bus clocks/64 to timeout in the case that one or
73 more descriptor completions are queued without reaching the count
74 threshold. Range is 1-65535.

84 Selecting this will offload crypto for users of the
85 scatterlist crypto API (such as the linux native IPSec
86 stack) to the SEC4 via job ring.

94 default y
95 select CRYPTO_AUTHENC
96 select CRYPTO_BLKCIPHER
97 help
98 Selecting this will use CAAM Queue Interface (QI) for sending
99 & receiving crypto jobs to/from CAAM. This gives better performance
100 than job ring interface when the number of cores are more than the
101 number of job rings assigned to the kernel. The number of portals
102 assigned to the kernel should also be more than the number of
103 job rings.
