Thank you all for ur valuable discussion (temp dir) and suggestions related
to highmem/PAE and x86_64.
I have another thing to ask related to debugging...i want to check the
routines which will be involved in the memory management.
According to the design of UML, it has its own VM system. If

Interesting. I wonder how that works? (PAE on x86 only lets you have 64G.)
Thats only an limitation of the CPU support for PAE. As UML is using
mmap() other limits apply and these limits is mainly set by the UML
pagetable structures.
But an individual

Linux needs to have one struct page for each physical mem page, which in
the
simple case of UML are placed in one memmap array.
This array needs to be accessible permanently to the kernel, i.e. it
has to be in low-mem. AFAIK, one struct page is 44 bytes in size, thus the
array is about 1% of

check the scalability limits of the parent kernel for memory management,
will UML be useful..?
Jeff Dike already answered this. (He's the UML maintainer.)

Mr. Sharma,
What you are trying to do will work, but not for large amounts of
memory. UML runs the client using a single user mode memory block as
the entire client's core. Thus

The client kernel's highmem suport is unlikely to do much, I'd think.
Not unless it's unmapping and remapping multiple mmaps.
It does this, indeed and sadly (that's why it's so slow).
