ioreq shared buffer page is a necessary for each VM. So separate VM creating and shared buffer page setup into two ioctls is meaningless. This patch intends to move the ioreq shared buffer page setup into IC_CREATE_VM ioctl. With this change, we can create vhm ioreq client just after CREATE_VM step. We need be careful with the compatibility. To achieve it safely, we will do, 1) Do shared page setup in IC_CREATE_VM, what this patch do exactly 2) Move the shared page setup action into vm creating in DM. 3) Remove the ioctl IC_SET_IOREQ_BUFFER in kernel.

This patch handles ppgtt update from g2v notification. It read out ppgtt pte entries from guest pte tables page and convert them to host pfns. It creates local ppgtt tables and insert the content pages into the local ppgtt tables directly, which does not track the usage of guest page table and removes the cost of write protection from the original shadow page mechansim. This patch is only for sos. v3: - Not pass pd pages, let GVT-g read from guest memory instead. v4: - fix page walk error. - remove insert_4lvl_sg. v5: - use cache_level from guest.

Since we plan using an RB tree for TCP retransmit queue to speedup SACK processing with large BDP, this patch exchanges skb->dev and skb->tstamp.

… process There is a requirement of a new interface for achieving below functionalities: 1) Need to provide Client based detailed information about the distribution of Graphics memory 2) Need to provide an interface which can provide info about the sharing of Graphics buffers between the clients. The client based interface would also aid in debugging of memory usage/consumption by each client & debug memleak related issues. With this new interface, 1) In case of memleak scenarios, we can easily zero in on the culprit client which is unexpectedly holding on the Graphics buffers for an inordinate amount of time. 2) We can get an estimate of the instantaneous memory footprint of every Graphics client. 3) We can now trace all the processes sharing a particular Graphics buffer. By means of this patch we try to provide a sysfs interface to achieve the mentioned functionalities. There are two files created in sysfs: 'i915_gem_meminfo' will provide summary of the graphics resources used by each graphics client. 'i915_gem_objinfo' will provide detailed view of each object created by individual clients.
