Hi all,
I am trying to run a simple pthreads program with MinorCPU, and it seems when
the program switches back to a thread that has been used before, it will cause
an error:
build/ARM/cpu/minor/execute.cc:914: panic: We should never hit the case where
we try to commit from a suspended thread as the streamSeqNum should not match
This panic does not occur when I use the default CPU type. Another issue is for
this program I only use 2 threads, but I have to create 5 CPUs, otherwise it
will fail to create the threads.
---------------------------------------------
Here is the test program:
#include <iostream>
#include <cstdlib>
#include <pthread.h>
using namespace std;
#define NUM_THREADS 2
void *PrintHello(void *threadid) {
long tid;
tid = (long)threadid;
cout << "Hello World! Thread ID, " << tid << endl;
pthread_exit(NULL);
}
int main () {
pthread_t threads[NUM_THREADS];
int rc;
int i;
for( i = 0; i < NUM_THREADS; i++ ) {
cout << "main() : creating thread, " << i << endl;
rc = pthread_create(&threads[i], NULL, PrintHello, (void *)i);
if (rc) {
cout << "Error:unable to create thread," << rc << endl;
exit(-1);
}
}
for( i = 0; i < NUM_THREADS; i++ ) {
cout << "main() : creating thread, " << i << endl;
rc = pthread_create(&threads[i], NULL, PrintHello, (void *)i);
if (rc) {
cout << "Error:unable to create thread," << rc << endl;
exit(-1);
}
}
pthread_exit(NULL);
}
------------------------------------------
To compile, I use:
aarch64-linux-gnu-g++ -static -pthread -DENABLE_THREADS -g -o test_pthreads
test_pthreads.cpp
And the configuration for gem5:
build/ARM/gem5.opt configs/example/se.py -c test_pthreads --cpu-type MinorCPU
-n 5 --l1d_size=64kB --l1i_size=16kB --caches
