- if there is any way already discussed or standardized to
make the system handle failures gracefully

In FreeBSD 6_2, if kmem_malloc is unable to find space it panics. The
relevant code is in vm_kern.c
if ((flags & M_NOWAIT) == 0)
panic("kmem_malloc(%ld): kmem_map too small: %ld
total allocated",
(long)size, (long)map->size);
Is there any
Hi
I am looking for any FreeBSD facility that will allow a userland process to
pass data to the kernel without doing a copyin or copyout e.g. using a
shared data structure (queue? ) for example? Any pointers will be useful
Thanks

Hi
I am trying to understand the difference in these three different memories.
Code comments in kern_malloc.c says that M_DEVBUF should be used for device
driver. I didn't however see any major difference between the three
memories. Can a device theoretically take up memory from M_TEMP (or
M_CACH
Hi
Is there any way to determine the physical memory(not the virtual address
space) being allocated to the kernel at any instant? The overall problem is
that once I allocate say 512 MB to the kernel (virutal address space)
through the config file at compile time, I want to figure out how much of

I am trying to understand the impact of memory allocation / deallocation
within the kernel. As I understand
a) Kernel memory is not pageable ie the one you get from using kernel
malloc(there may be exceptions)
b) Does this imply that if I have 1 GB of RAM - then I cannot reserve more
than 1 GB of
Hi
I am trying to explore the option avoiding copyin and copyout when mode
switches from user to kernel and vice versa. One way to achieve this, as I
understand, is to make the memory address (which contain the data to be
copied) non pageable. Then just pass the addresses to the kernel and the
data
