I am writing code for Linux on a x86-64 machine. It is working perfectly on x86-64, but I ported the same code to an ARM based device and now I am getting error: Invalid argument for timer code. Following is my timer code:
/**
* FUNCTION NAME : startRetryCount
* @brief start the retry count
* @param isAuth: if true start retry for Auth message else for Normal message
* @return true if success and false if not
*/
bool startRetryCount(bool isAuth)
{
m_RetryAuth = isAuth;
stopRetryCount();
struct sigevent sigev;
struct itimerspec itval;
struct itimerspec oitval;
struct sigaction sigact;
if(sigemptyset(&sigact.sa_mask) == -1)
{
printLog(LOG_ERROR,"[%s:%d#%s] <<<< sigemptyset >>>> : %s\n",
__FILE__,__LINE__,__func__,strerror(errno));
}
sigact.sa_flags = SA_SIGINFO;
sigact.sa_sigaction = signalHandler;
m_RetryCount = ConfigureManager_SingleTon::getInstance()->getRetryCount();
printLog(LOG_INFO,"**Retry Count Started**\n");
printLog(LOG_INFO,"Number of Retry Count:%d\n",m_RetryCount);
printLog(LOG_INFO,"Retry time is:%d\n",
ConfigureManager_SingleTon::getInstance()->getRetryTime());
// set up sigaction to catch signal
if (sigaction(SIGTIMER, &sigact, NULL) == -1)
{
printLog(LOG_ERROR,"[%s:%d#%s] <<<< time_settime >>>> : %s\n",
__FILE__,__LINE__,__func__,strerror(errno));
return false;
}
//Create the POSIX timer to generate signo
sigev.sigev_notify = SIGEV_SIGNAL;
sigev.sigev_signo = SIGRTMAX;
sigev.sigev_value.sival_int = RETRY_ID;
if (timer_create(CLOCK_REALTIME, &sigev, &m_RetryTimerId) == 0)
{
itval.it_value.tv_sec = ConfigureManager_SingleTon::getInstance()->getRetryTime();
itval.it_value.tv_nsec = 0L;
itval.it_interval.tv_sec = itval.it_value.tv_sec;
itval.it_interval.tv_nsec = itval.it_value.tv_nsec;
if (timer_settime(m_RetryTimerId, 0, &itval, &oitval) != 0)
{
Utility_SingleTon::printLog(LOG_ERROR,"[%s:%d#%s] <<<< time_settime >>>> %s\n",
__FILE__, __LINE__,__func__,strerror( errno ));
return false;
}
}
else
{
printLog(LOG_ERROR,"[%s:%d#%s] <<<< timer_create >>>> %s",
__FILE__, __LINE__,__func__,strerror( errno ));
return false;
}
return true;
}
/**
* FUNCTION NAME : stopRetryCount
* @brief stop the retry count
*/
voidstopRetryCount()
{
if(m_RetryTimerId != NULL)
{
if(timer_delete(m_RetryTimerId) != 0)
{
printLog(LOG_ERROR,"[%s:%d#%s] Timer delete error [%d]=%s\n",__FILE__, __LINE__,__func__,errno,strerror(errno));
}
m_RetryCount = 0;
m_RetryTimerId = NULL;
printLog(LOG_INFO,"Retry Timer Stopped!\n");
}
}
Print log of errors is:
[src/manager.cpp:686#stopRetryCount] Timer delete error [22]=Invalid argument
I have tried a lot to find what is bothering the ARM based device, but unfortunately I am not able to resolve the issues. Any help would be highly appreciated.
Edited:
To simulate my condition, I have created sample program, now I came to know that on mistral SAM-9 processor Timer and thread combinedly not working, If I start the timer in the main thread and if I tries to stop that timer through child thread, then it is giving that error. Here is the sample.cpp file source:
#include "devicetimer.h"
int DeviceTimer::counter = 0;
timer_t DeviceTimer::testTimer1Id = 0;
void DeviceTimer::timer1Stop()
{
if(testTimer1Id != 0)
{
if(timer_delete(testTimer1Id) == -1)
{
printf("Timer Delete Error\nError Number = %d\nError Message = %s\n",errno,strerror(errno));
exit(1);
}
else
{
printf("Timer Delete Successfully\n");
}
}
}
void DeviceTimer::signalHandler(int signo, siginfo_t* info, void* context)
{
if (signo == SIGTIMER)
{
printf("counter %d\n\n",++counter);
}
}
int DeviceTimer::timer1start()
{
struct sigevent sigev; //signal event struct
struct itimerspec itval;
struct itimerspec oitval;
struct sigaction sigact;
sigemptyset(&sigact.sa_mask);
sigact.sa_flags = SA_SIGINFO;
sigact.sa_sigaction = signalHandler;
// set up sigaction to catch signal
if (sigaction(SIGTIMER, &sigact, NULL) == -1)
{
printf("time_settime error \n");
return -1;
}
//Create the POSIX timer to generate signo
sigev.sigev_notify = SIGEV_SIGNAL;
sigev.sigev_signo = SIGTIMER;
sigev.sigev_value.sival_int = 2;
if (timer_create(CLOCK_REALTIME, &sigev, &testTimer1Id) == 0)
{
itval.it_value.tv_sec = 1;
itval.it_value.tv_nsec = 0L;
itval.it_interval.tv_sec = itval.it_value.tv_sec;
itval.it_interval.tv_nsec = itval.it_value.tv_nsec;
if (timer_settime(testTimer1Id, 0, &itval, &oitval) != 0)
{
printf("Error in set time \n");
return -2;
}
}
else
{
printf("Error in creating timer \n");
return -3;
}
return 0;
}
void* DeviceTimer::threadFunction(void* data)
{
DeviceTimer *deviceTimer = (DeviceTimer *) data;
while(1)
{
printf(".\n");
usleep(100000);
if(counter > 25)
{
deviceTimer->timer1Stop();
break;
}
}
return NULL;
}
void DeviceTimer::startThread()
{
if(pthread_create(&m_Thread, NULL, DeviceTimer::threadFunction, this) != 0)
{
printf("Error in creating Thread\n");
exit(1);
}
}
int main()
{
DeviceTimer deviceTimer;
deviceTimer.timer1start();
deviceTimer.startThread();
while(1)
{
}
return 0;
}
And following is the output:
counter 26
Timer Delete Error
Error Number = 22
Error Message = Invalid argument
If anyone experinced the same problem then, please help me to resolve this issue.
Thanks & BR, Yuvi
