2009-04-09 01:21:18     CPLB miss in pthread

Nicole Otsuka (CHINA)

Message: 72442   

 

hello, i met some problem in my application software

 

the version of the uclinux is uclinux-dist-trunk-svn-7715

 

i complied a static mplayer library which can play mp3.

 

if i call the main function of the lib in a MAIN(   void main(){mplayer_main();}  ),it works well without no crash.

 

BUT if i create a thread and call the lib_main in the pthread,it will be crashed.

 

the error info is:

 

============size=12288

mplayer -fs -zoom -framedrop /iicore/musics/planetarium.mp3 -msglevel all=-1 -loop 0

MPlayer 1.0rc2-4.1.2 (C) 2000-2007 MPlayer Team

Bus error

 

 

 

 

btw,this application works well in the uClinux-dist-2008R1.5-RC3 and the error info havent show some NULL POINTER problem,so i think it may not be a bug in my application.

 

thank you,

 

Nicole

are you smashing the stack ?  pthread stacks are pretty tiny by default.

@mike

 

thank you for your reply

 

the info in the error print : ============size=xxxx means the vaule of get_pthreadstack (the first print is the size before create pthread,and the other is the size after i have done the create)

 

and i also tried to set more size like 16MB....but it also crashed...

i dont know what "get_pthreadstack" is ... that is not a standard function or you've typo-ed it

 

at any rate, i think you're misinterpreting the result.  there is absolutely no way your thread's stack size is 4294967292 bytes.  more likely that is a signed negative value you're interpreting as an unsigned.

 

if you arent setting the thread stack size manually, then the default will be pretty small.

hi mike,

the error info is printed by the code above and "===size=4294967292" is the second printf.

 

btw,

i also tried to set 32K(64K,128K,1MB) for the stack before i used pthread_create.Then the result of the second printf is always "4294967292

"

if i set 32K(64K,128K,1MB) for the stack after pthread_create ,the value of the getstacksize is right.BUT the progrom also crashed.

 

 

can you give some idea? thank you very much~

 

Nicole

Can you turn on CONFIG_DEBUG_BFIN_NO_KERN_HWTRACE - and try again?

Nicole,

 

What is the result of "turn on CONFIG_DEBUG_BFIN_NO_KERN_HWTRAC", as Robin suggested?

 

If 1MB stack size cannot work, how about try 2MB, 4MB...

 

Also you may try to set and check stack size this way:

 

pthread_attr_init ();

pthread_attr_setstacksize (1MB);

status = pthread_attr_getstacksize (&size); // check before pthread_create()

 

if (status != 0) .. // check staus

 

pthread_create();

thank you, robin and yi

 

i turn on the CONFIG_DEBUG_BFIN_NO_KERN_HWTRAC and tried again in the way yi said

 

but the size of the stack seams to be changed after pthread_create

 

 

 

the handware trace are as follows:

 

root:/iicore> ./a.out

============size=8388608             /*print stacksize before pthread_create*/

mplayer -fs -zoom -framedrop /iicore/musics/planetarium.mp3 -msglevel all=-1 -loop 0

So you are using 8MB thread stack size and still get the exception.

 

You can try debug as:   docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:debugging_applications#analyzing_traces

 

See what happens around here: Source : <0x037a4676> [ /lib/libpthread.so.0 + 0x4676 ] 0x320e

You did not call pthread_create() correctly:

 

> pthread_attr_init (&Mp3PlayThreadHandle);

 

>     res = pthread_create(&Mp3PlayThreadHandle, // this should be a pthread_t object, not pthread_attr_t

>                     NULL, 

>                     Mp3PlayThreadRoutine,

>                     NULL);

 

Correct way:

 

int pthread_create(pthread_t *thread, const pthread_attr_t *attr,

    void *(*start_routine)(void*), void *arg);

 

That explains why getstacksize() not correct after pthread_create.
