Can we allocate physical memory starting from a given address?
 

Hi,
Is it possible to allocate physical memory starting from a fixed known location?
e.g. I wanted to allocate 1000 bytes from 0x80005a00.
If it is possible, then plz let me know how to do it?
Thanks in advance,

You've got that much RAM ?

No - at least not from userspace.

Yes, my RAM base address is from 0x8000:0000.
Is it possible to do from kernel space?
I need to store some data before system enters suspend at a fixed known location and read it back after resume.
Can some one plz help.

I'd say yes you can but it may depend on how you want to use that.

Hi,
Thanks for your reply.
Can you plz provide me a code snippet/ pseudo code to do this?
Thanks in advance.
