Hi Venkat,
In a 512MB with 1024MB swap how much space is allocated to
kernel and user,
That depends upon your kernel configuration (what all components you
have selected determine the memory footprint size) and a lot of other
things.
According to previous discussion it is 1GB for kernel and 3 GB for user if
we have 4GB of momory.
The 3 GB / 1 GB split is only a split in the virtual memory address
space. It means that though the kernel may use more than 1 GB of
physical memory, but it may only access 1 GB of it at a time, because
the kernel can use only 1 GB of virtual addresses. So it would need to
temporarily map / unmap the extra memory.
Thanks,
Rajat
