search for: memory_sharing

Hi, guys, I''m sorry to disturb you. I am a student. I want to use Xen to do some test about memory sharing between two domain. I am a newbie in Xen memory sharing. I want to set up a environment. I search on the internet. I find some patch for old version. However, I want to running on Xen 4.1 or 4.2 version. Does this still work? Can you help me? Can you give some instruction on this?

The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature. Please review. v2: - update mem_event_check_ring arguments, check domain rather than domain_id - check ring_full first because its value was just evaluated - check if ring buffer is initialized before calling mem_access_domctl/mem_paging_domctl
