OSA_thrCreate failed 11

Pls print the number of threads in the process by checking under /proc/<pid>/task folder when the OSA_thrCreate error occurs. Also share logs of mallinfo() when you hit the error condition .Below is example code to print number of threads:

#include <dirent.h>
#include <sys/types.h>
#include <unistd.h>

Int32 OSA_GetThreadCount()
{
    Int32 file_count = 0;
    DIR * dirp;
    struct dirent * entry;
    pid_t cur_pid;
    char thread_count_path[1024];

    cur_pid = getpid();
    printf("\nOSA: Getting thread count for process:%d\n",cur_pid);
    snprintf(thread_count_path,sizeof(thread_count_path) - 1,"/proc/%d/task",cur_pid);
    thread_count_path[sizeof(thread_count_path) - 1] = 0;

    printf("\nOSA: Thread Count paths:%s\n",thread_count_path);
    dirp = opendir(thread_count_path); /* There should be error handling after this */
    if (dirp == NULL)
        return -1;
    while ((entry = readdir(dirp)) != NULL) {
        file_count++;
    }
    closedir(dirp);
    printf("\nOSA: Thread Count :%d\n",file_count);
    return file_count;
}

hi Badri ,i do some test like you say.i just do the following operator

Vsys_params_init(&vsysParams);
Vsys_init(&vsysParams);

then 

do some about the dis init operator,and i don't create any about the dis link

next i call the Vdis_start()

last i do the exit operator

Vdis_hdmiCtrl_stop()

Vsys_deConfigureDisplay();

Vdis_exit();

Vsys_exit();

all the above is in a while(1)

i found the thread count after the sysinit is increase

when the thread created failed ,the statistic result is following 

Total non-mmapped bytes (arena): 135168
# of free chunks (ordblks): 2
# of free fastbin blocks (smblks): 0
# of mapped regions (hblks): 0
Bytes in mapped regions (hblkhd): 0
Max. total allocated space (usmblks): 0
Free bytes held in fastbins (fsmblks): 0
Total allocated space (uordblks): 50960
Total free space (fordblks): 84208
Topmost releasable block (keepcost): 84168

i found that in the dis init funtion

Vdis_init() call the function Vdis_hdmiCtrl_init()

will create a thread.

but when exit the dis,how to stop and exit the thread 

tks

Below is the code to print thread id. I am not sure if this function is included in your RDK codebase:

#include <unistd.h>
#include <sys/syscall.h>
#include <sys/types.h>

void
OSA_printTID(const char *threadName)
{
    pid_t tid;

    tid = syscall(SYS_gettid);
    printf("[HOST] \nThreadName:%s,ThreadID:%d\n",threadName,tid);
}

Pls add below line in file /dvr_rdk/mcfw/src_linux/mcfw_api/ti_vdis_hdmi_ctrl_priv.c

static void *Vdis_hdmiControlThread(void * ctrlInst)

    VDIS_HDMI_CNTRL_INST *pCtrlInst = (VDIS_HDMI_CNTRL_INST *) ctrlInst;
    int status = OSA_SOK;
    struct ti81xxhdmi_status hdmiStatus;
    OSA_MsgHndl *pMsg;
    int sendEvent;
 char threadName[128]; snprintf(threadName,sizeof(threadName),"%s_%x",__func__,0); threadName[sizeof(threadName) - 1] = 0; OSA_printTID(threadName); 

Note down the thread id in each iteration and then do ls -l /proc/<pid>/task/ and check if the thread id not deleted in each iteration matches the HDMI control thread. Exiting the thread handler function should delete the thread so I am not sure if this is the thread that is not deleted.

Hello,

Thank you for sharing the solution.
