Using uadk_adapter_worker to record driver and resources.
so adding multi driver is adding workers.
struct uadk_adapter_worker {
struct wd_alg_driver *driver;
struct wd_ctx_config *ctx_config;
struct wd_sched *sched;
struct wd_ctx_config_internal config;
struct wd_async_msg_pool pool;
bool valid;
};
struct uadk_adapter {
unsigned int workers_nb;
enum uadk_adapter_mode mode;
struct uadk_adapter_worker workers[UADK_MAX_NB_WORKERS];
struct uadk_adapter_ops ops;
};
struct wd_digest_setting {
struct uadk_adapter *adapter;
}
struct wd_digest_sess {
struct uadk_adapter_worker *worker;
pthread_spinlock_t worker_lock;
}

case 1: sync or async error, switch worker case 2: roundrobin mode, switch worker 10 times

Add zlib drv to to simulate cpu instruction accelerator Btw, zlib is required. apt-get install zlib1g-dev Signed-off-by: Zhangfei Gao <[email protected]>
Will use hisi_zlib to test adapter, so let UADK_ALG_SOFT register to uadk Signed-off-by: Zhangfei Gao <[email protected]>
will switch between zlib and zip uadk_tool benchmark --alg zlib --mode sva --opt 0 --sync --pktlen 1024 --seconds 1 --thread 1 --multi 1 --ctxnum 1 --init 2 Signed-off-by: Zhangfei Gao <[email protected]>
export UADK_CONF=/home/linaro/work/uadk/uadk.conf Example: uadk.conf mode=1 driver_name=hisi_zip driver_name=hisi_zlib If env UADK_CONF exist, only parse UADK_CONF and add to adapter->workers[] one by one. So the first driver has higher priority Signed-off-by: Zhangfei Gao <[email protected]>
all workers need to be initialized in init2, using default type
worker->xxx is common, use sess worker lifetime instead
init sched_key[] for each workers since they may different
miss sess->worker_lifetime = 0 when switch worker, compute again
mode=1 pass in from uadk.conf export UADK_CONF=/home/linaro/work/uadk/uadk.conf This reverts commit 45c62bb.

if UADK_CONF, worker sequence is decided by UADK_CONF otherwise, workers is listed as drv->priority Signed-off-by: Zhangfei Gao <[email protected]>

1.增加一个workers[2]数组，
a.workers 数组默认是按优先级排序。
b.也可以通过config文件，export UADK_CONF=xxx/uadk.conf
i.系统中存在多个驱动，只选择其中2个，
ii.可以切换优先级，前面的驱动优先级高
c.struct worker 不仅包括驱动，还包括驱动需要的资源
d.现在worker[]只有2个，可以修改宏改成多个。
2.要求：init完后 所有worker均初始化好，工作时随便选哪个worker 都能工作，方便随时切换。
3.工作切换
a.默认primary_mode，worker[0]出错 -> worker[1] 10次 -> worker[0]
b.roundrobin_mode, worker[0] 10次 -> worker[1] 10次 -> worker[0] 10次 -> ...
