Hi Abu...
I check the output together with your C source code again. According to
this:
if(poarray==NULL)
{
printf("\nError in allocating\n");
exit(1);
}
and this:
if(p2 == NULL)
{
printf("OOM PROBLEM");
}
I should see those messages on the output log, but I find none. So IMHO
the failure of memory allocation didn't happen when you called
malloc()....however...
I see some message like these:
YoKu: PXA AC97 Driver loaded (5-Nov-05)
insmod: page allocation failure. order:5, mode:0xd0
Right after that, I found this:
DMA free:944kB min:512kB low:640kB high:768kB active:6444kB
inactive:1116kB present:16384kB pages_scanned:0 all_unreclaimable? no
lowmem_reserve[]: 0 0 0
Normal free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB
present:0kB pages_scanned:0 all_unreclaimable? no
lowmem_reserve[]: 0 0 0
HighMem free:0kB min:128kB low:160kB high:192kB active:0kB inactive:0kB
present:0kB pages_scanned:0 all_unreclaimable? no
lowmem_reserve[]: 0 0 0
DMA: 106*4kB 11*8kB 5*16kB 3*32kB 2*64kB 1*128kB 0*256kB 0*512kB
0*1024kB = 944kB
So, I am thinking, could it be caused by such a kernel module asking for
bigger memory chunks than currently available? Or it simply asks memory
block other than DMA zone?
I am sorry if I can't help too much, it is up to you to use my advice to
pinpoint the real problem.
regards,
Mulyadi
