this may be a trivial question for many of you
but i am confused in doing memory allocation in the
sys/malloc.h has function prototypes for malloc()
kern/kern_malloc.c defines the malloc()
the malloc() definition is
malloc(size, type, flags)
unsigned long size;
struct malloc_type *type;
i understand the size and flags but what shall i
do with the malloc_type.
suppose i want to allocate 1024 bytes then how
should i call the malloc ?
i set -->
type=???? (i don't know what/how to initialize
Next thing is that i want to make the kernel process
network packets very fast.
i think of increasing the mbuf and cluster size.
i want to if there will be any effect on increasing
the mbuf and cluster size.
what would be an appropriate size of mbuf and cluster
if I use
i. 512 MB RAM
iI. 1024 MB RAM
which parts of the kernel will be affected by
changing the mbuf and cluster size ?
i think somebody maybe able to help me.
