The merge of PAE support introduced the intpte_t type and PRIpte format specifier. Most of the shadow mode code was fixed, but debugging printks were not; this broke the compile if shadow mode debugging was enabled. The attached patch should fix the problem. Not tested with PAE enabled, but it shouldn''t make anything worse than it already is. Signed-off-by: Michael Vrable

The README at the location shared by John says "DSA is undergoing significant changes and may not be entirely stable or correct. See lib/DSA/README" So, I was wondering from where should one pick the code. Although I will start my analysis and see how results turn out to be. But any comments on this line will be helpful.

Thanks Everyone for the info. I am planning to work with DSA on llvm-2.9. Hope it is working as John mentioned.

Hi: There is a code sample in <The Definite Guide to the Xen Hypervisor>, chapter 4, "Using Grant Tables". The code sample is as following: #include <public/xen.h> extern void * shared_page; extern grant_entry_t * grant_table; void offer_page() { uint16_t flags; /* create the grant table*/ gnttab_setup_table_t setup_op;

I''m experiencing total grant table corruption on a system and I''m hoping my symptoms will ring a bell with a member of the Xen developer community. The setup is Xen 4.0.0-RC2 (OpenSUSE 11.2 package) on a Nehalem system. The sole guest instance is 64bit FreeBSD running in HVM mode, a single vcpu, and a PCI passed-through LSI Logic 1068e SAS controller. FreeBSD is running

The first 7 patches are scheduled for mainline as they were merged + tested without any hiccups. These last few patches I'll wait and see. If nothing blows up on linux-next perhaps I'll include them to Linux for mainline during the next merge

Hi all, I'm looking into using LLVM to do some optimisations of Fortran code. As part of this, I've been trying to build the frontend with f95 support. At the moment, I'm trying to resolve undefined symbol problems for code defined in c-common.c + elsewhere - I'm taking the temporary approach of copy-pasting it into a new file, and linking that in. I have no idea if it will

Hi, I am trying to export a memory page of dom0 to a domU in readonly mode. In dom0, I grant access permission to that domU. In domU, I did HYPERVISOR_grant_table_op(GNTTABOP_map_grant_ref, map, res->nr_pages); All these functions returned successfully. But when I tried to access data in the mapped memory page, all data I got is 0. Is there any restriction that preventing dom0 pages from

Here''s another general comment for discussion... The bottom of page 18 in the Xen Roadmap proposal recommends considering how to "export byte stream (TCP) data between domains in a high performance fashion." For communications that occur between domains on a single physical machine, it would seem logical to setup a new address and protocol family within Linux that could be
