Hi,
I'm having a problem with pthread_create failing with a custom kernel
(problem doesn't happen with GENERIC). If I use a null pthread_attr_t arg,
pthread_create returns EAGAIN. If feed it a pthread_attr_tag, then
lib/libc_r/uthread/uthread_create.c: pthread_create() panics.
After noising around in uthread_create(), it seems that at
line 143:
/* Stack: */
if (mmap(stack, PTHREAD_STACK_DEFAULT,
PROT_READ | PROT_WRITE, MAP_STACK,
-1, 0) == MAP_FAILED) {
ret = EAGAIN;
free(new_thread);
mmap is consistantly failing (returing ENOMEM).
when I use a custom stacksize, then the malloc succeeds, however, the
gc_thread creation fails (because it calls pthread_create using defaults).
What options could I change in the kernel conf file that would break all my
pthread using programs?
suggestions? sources were cvsup'd today....
respond in email also please...
Thanks in advance
