adapter part 2,

  1. add adapter
  2. use workers to record each resources, each work should work independently
  3. switch between works

uadk: use wd_find_msg_in_pool to replace wd_xxx_get_msg
fd309a0 
Use the common func wd_find_msg_in_pool to replace the different
wd_xxx_get_msg via passing the pool to the drv.priv->config.poll

uadk: move wd_util and wd_shced to libwd
425cd46 
The wd_util.c and wd_shced.c should be in libwd.so
No need to export in every algo.so

uadk_tool: use static wd_sched instead of temp var
e0b3769 
Now wd_init_sched will copy sched memory,
later the &sched will be directly used without copy.
So use static var instead of temp var, which will be freed.

uadk: poll_ctx adds para wd_sched
1a97a8e 
poll_ctx adds para wd_sched to transfer para,
since different driver may use different pool.

also takes idx to search the idx'th drv

uadk: add adapter.c
f3875f4 
Using uadk_adapter_worker to record driver and resources.
So adding multi driver is adding workers.
The worker priority and mode can be set by env UADK_CONF.

For export UADK_CONF=TO_PATH/uadk.conf

    Example: uadk.conf
    mode=1
    driver_name=isa_ce_sm3
    driver_name=hisi_sec2

If env UADK_CONF exist, only parse UADK_CONF and add to
adapter->workers[] one by one. So the first driver
has higher priority

Otherwise, parse all drivers and choose the top two
priorities drivers to adapter->workers[]

uadk: make hw sw co-work

Using uadk_adapter_worker to record driver and resources.
so adding multi driver is adding workers.
To make sure different worker can work.

uadk: support switch between hw and sw
66d83f7 
case 1: sync or async error, switch worker
case 2: roundrobin mode, switch worker after worker->looptime (10)

adapter: add LOOP_KEY "looptime"
b5aff1d 
By default each worker loop 10 times in roundrobin mode,
except looptime is set in UADK_CONF

For example:
uadk.conf
looptime=5
mode=1

如何使用

  1. 默认，没有配置文件，
    选最高优先级两个驱动，primary 模式，工作时最高优先级驱动，worker[0], 出错时才切换次优先级驱动worker[1], 运行10次（looptime）再尝试切回worker[0]

命令和之前一样
example:
numactl --cpubind=0 --membind=0 uadk_tool benchmark --alg sm3 --mode instr --opt 0 --sync --pktlen 1024 --seconds 20 --multi 1 --thread 8 --ctxnum 8 --init2

  1. 提供配置文件, 根据配置文件依次worker[0], worke[1], 可以配置round robin模式，轮流跑10次（looptime 可配置）
    example:
    vi uadk.conf
    mode=1
    driver_name=isa_ce_sm3
    driver_name=hisi_sec2
    export UADK_CONF=xxx/uadk.conf
    运行命令

  2. config 每次运行生效，可以更换驱动顺序，
    参数有
    mode=1 （默认是primary模式，出错才选择worker[1], mode=1时round robin, 两个驱动依次执行looptime次）
    looptime=5 (默认10，)

  3. 工作机制
    setting -> adapter -> workers[]
    sess->worker: alloc_sess 会选择worker[0], 某些时候sess->worker 会切换，如果出错或者round robin
    工作时，worker=sess->worker

细节参考
