Subject: [RFC PATCH 2/6] crypto: benchmark - add a crypto benchmark tool

Provide a crypto benchmark to help the developer quickly get the
performance of a algorithm registered in crypto.

Due to the crypto algorithms have multifarious parameters, the tool
cannot support all test scenes. In order to provide users with simple
and easy-to-use tools and support as many test scenarios as possible,
benchmark refers to the crypto method to provide a unified struct
'crypto_bm_ops'. And the algorithm registers its own callbacks to parse
the user's input. In crypto, a algorithm class has multiple algorithms,
but all of them uses the same API. So in the benchmark, a algorithm
class uses the same 'ops' and distinguish specific algorithm by name.

First, consider the performance calculation model. Considering the
crypto subsystem model, a reasonable process code based on crypto api
should create a numa node based 'crypto_tfm' in advance and apply for
a certain amount of 'crypto_req' according to their own business.
In the real business processing stage, the thread send tasks based on
'crypto_req' and wait for completion.

Therefore, the benchmark will create 'crypto_tfm' and 'crypto_req' at
first, and then count all requests time to calculate performance.
So the result is the pure algorithm performance. When each algorithm
class implements its own 'ops', it needs to pay attention to the content
completed in the callback. Before the 'ops.perf', the tool had better
prepare the request data set. And in order to avoid the false high
performance of the algorithm caused by the false cache and TLB hit rate,
the size of data set should be larger than 'crypto_req' number.
The 'crypto_bm_ops' has following api:
 - init & uninit
 The initialize related functions. Algorithm can do some private setting.
 - create_tfm & release_tfm
 The 'crypto_tfm' related functions. Algorithm has different tfm name in
 crypto. But they both has a member named tfm, so use tfm to stand for
 algorithm handle. The benchmark has provides the tfm array.
 - create_req & release_req
 The 'crypto_req' related functions. The callbacks should create a 'reqnum'
 'crypto_req' group in struct 'crypto_bm_base'. And the also suggest
 prepare the request data in this function. In order to avoid the false
 high performance of the algorithm caused by the false cache and TLB hit
 rate, the size of data set should be larger than 'crypto_req' number.
 - perf
 The request sending functions. The registrant should use parameter 'loop'
 to send requests repeatly. And update the count in struct
 'crypto_bm_thread_data'.

Then consider the parameters that user can configure. Generally speaking,
the following parameters will affect the performance of the algorithm:
tfm number, request number, block size, numa node. And some parameters
will affect the stability of performance: testing time and requests sent
number. To sum up, the benchmark has following parameters:
 - algorithm
 The testing algorithm name. Showed in /proc/crypto.
 - algtype
 The testing algorithm class. Can get the algorithm class by echo 'algtype'
 to /sys/module/crypto_benchmark/parameters/help.
 - inputsize
 The testing length that can greatly impact performance. Such as data size
 for compress or key length for encryption.
 - loop
 The testing loop times. Avoid performance fluctuations caused by
 environment.
 - numamask
 The testing bind numamask. Used for allocate memory, create threads and
 create 'crypto_tfm'.
 - optype
 The testing algorithm operation type. Can get the algorithm available
 operation types by cat /sys/module/crypto_benchmark/parameters/help
 with specified 'algtype'.
 - reqnum
 The testing request number for per tfm. Used for test asynchrony api
 performance.
 - threadnum
 The testing thread number. To simplify model, create a 'crypto_tfm' per
 thread.
 - time
 The testing time. Used for stop the test thread.
 - run
 Start or stop the test.

Users can configure parameters under
/sys/modules/crypto_benchmark/parameters/.
Then echo 1 to 'run' to start the test. And if they want to stop the
test, just echo 0 to 'run'.
