Hi:
This sounds a lot like "Cross Memory Support" (eg CROSS_MEMORY_ATTACH option) introduced in Linux 3.2:
http://kernelnewbies.org/Linux_3.2#head-a5e26c6275e85a5c9c41873fbab96bd38d93...
Cross Memory Support add two syscalls: - process_vm_readv() : read from a process memory - process_vm_writev() : write to a process memory
Details can be found here:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdif...
And documentation here:
http://www.man7.org/linux/man-pages/man2/process_vm_readv.2.html http://ozlabs.org/~cyeoh/cma/process_vm_readv.txt
GREAT! I will study these documentation and source code.
[...] The kernel I use is 2.6.32.
BTW, why use a kernel released 3 years ago for such new development ? Kernel 2.6.32 was released the 3rd of december 2009. Even the -rt project switch to newer kernel (eg. no less than 3.0, and up to 3.4), see http://rt.wiki.kernel.org/
You should at least switch to a current long term support kernels, for example Linux 3.4. See http://www.kroah.com/log/linux/stable-status-08-2012.html
Because I use the stable distribution of Debian and all the packages for kernel modules and kernel building are for these version as you can see: Package kernel-image-2.6.32-5-486-di squeeze (stable) (debian-installer): Linux kernel binary image for the Debian installer 1.99+squeeze8: i386 Thanks Yann Droneaud PAP
