These two patches were originally part of the XSM series that I have posted, and remain prerequisites for that series. However, they are independent of the XSM changes and are a useful simplification regardless of the use of XSM. The Acked-bys on these patches were provided before rebasing them over the copyback changes in 26268:1b72138bddda, which had minor conflicts that I resolved. [PATCH

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

This patch set adds XSM security labels to useful debugging output locations, and fixes some assumptions that all interrupts behaved like GSI interrupts (which had useful non-dynamic IDs). It also cleans up the policy build process and adds an example of how to use the user field in the security context. Debug output: [PATCH 01/10] xsm: Add security labels to event-channel dump [PATCH 02/10] xsm:

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.
