概述
使用mstar 648开发出现待机失败重启问题,根据分析是因为某个I2c设备未正确读取导致关机时有个线程无法关闭导致无法正常待机
首先待机失败log

从log可以看出执行removeStrThreadItem时AudioMonitor项出现失败问题
removeStrThreadItem方法代码
supernovaMStarSDKsrcstrmapi_str.cpp
void mapi_str::removeStrThreadItem()
{
pthread_t ptid = pthread_self();
char name[32];
int intPTHChk;
prctl(PR_GET_NAME,(unsigned long)name);
intPTHChk = PTH_RET_CHK(pthread_mutex_lock(&m_mutex));
ASSERT(intPTHChk == 0);
for (vector<ST_STR_THREAD_ITEM>::iterator it=m_StrThreadItems.begin(); it!=m_StrThreadItems.end();)
{
if (it->ptid == ptid)
{
it = m_StrThreadItems.erase(it);
printf("mapi_str::removeStrThreadItem ptid=%p m_StrThreadItems.size()=%d,this=%p, name=%sn", (void*)ptid, m_StrThreadItems.size(), this, name);
}
else
{
++it;
}
}
intPTHChk = PTH_RET_CHK(pthread_mutex_unlock(&m_mutex));
ASSERT(intPTHChk == 0);
}
从代码可以看出当出现问题时m_StrThreadItems数组并未能删除问题线程记录
接着查看mapi_str::waitforAllThreadSuspend 打印log处代码
void mapi_str::waitforAllThreadSuspend()
{
printf("mapi_str::waitforAllThreadSuspend begin
m_StrThreadItems.size()=%d,m_StrThreadItemSuspendNum=%u,this=%p,pthread_self()=%p,getpid()=%dn", m_StrThreadItems.size(), m_StrThreadItemSuspendNum, this,
(void*)pthread_self(), getpid());
while(m_StrThreadItems.size() != m_StrThreadItemSuspendNum)
{
for (unsigned int i = 0; i < m_StrThreadItems.size(); i++)
{
printf("mapi_str::waitforAllThreadSuspend continue thread ptid=%p,
name=%sn", (void *)m_StrThreadItems[i].ptid, m_StrThreadItems[i].name.c_str());
}
for(int i=0;i<50;i++)
{
if(m_StrThreadItems.size() == m_StrThreadItemSuspendNum)break;
usleep(1000);
}
printf("mapi_str::waitforAllThreadSuspend continue
m_StrThreadItems.size()=%d,m_StrThreadItemSuspendNum=%u,this=%p,pthread_self()=%p,getpid()=%dn", m_StrThreadItems.size(), m_StrThreadItemSuspendNum, this,
(void*)pthread_self(), getpid());
}
printf("mapi_str::waitforAllThreadSuspend complete
m_StrThreadItems.size()=%d,m_StrThreadItemSuspendNum=%u,this=%p,pthread_self()=%p,getpid()=%dn", m_StrThreadItems.size(), m_StrThreadItemSuspendNum, this,
(void*)pthread_self(), getpid());
}
查看代码发现,啥都没干只是打印,阻塞时间?难道是在等有其他地方线程去把线程结束删除?分析这边应该就是导致系统待机失败,阻塞时间过长其他地方出现问题直接重启了
这时就有几种修改方法,第一种解决释放不了线程问题,第二种解决这个啥都不干在这阻塞的代码
明显第二种会简单很多添加代码:
void mapi_str::waitforAllThreadSuspend()
{
printf("mapi_str::waitforAllThreadSuspend begin m_StrThreadItems.size()=%d,m_StrThreadItemSuspendNum=%u,this=%p,pthread_self()=%p,getpid()=%dn", m_StrThreadItems.size(), m_StrThreadItemSuspendNum, this, (void*)pthread_self(), getpid());
while(m_StrThreadItems.size() != m_StrThreadItemSuspendNum)
{
for (unsigned int i = 0; i < m_StrThreadItems.size(); i++)
{
printf("mapi_str::waitforAllThreadSuspend continue thread ptid=%p, name=%sn", (void *)m_StrThreadItems[i].ptid, m_StrThreadItems[i].name.c_str());
}
for(int i=0;i<50;i++)
{
if(m_StrThreadItems.size() == m_StrThreadItemSuspendNum)break;
usleep(1000);
m_StrThreadItems.clear();
}
printf("mapi_str::waitforAllThreadSuspend continue m_StrThreadItems.size()=%d,m_StrThreadItemSuspendNum=%u,this=%p,pthread_self()=%p,getpid()=%dn", m_StrThreadItems.size(), m_StrThreadItemSuspendNum, this, (void*)pthread_self(), getpid());
}
printf("mapi_str::waitforAllThreadSuspend complete m_StrThreadItems.size()=%d,m_StrThreadItemSuspendNum=%u,this=%p,pthread_self()=%p,getpid()=%dn", m_StrThreadItems.size(), m_StrThreadItemSuspendNum, this, (void*)pthread_self(), getpid());
}
重新升级,验证问题成功解决,不过第二种虽然简单但是会不会引起什么问题呢?理论来说待机时候这个没影响,但是最优的解决方法还是第一种
