- use consistent error values (stop mixing of [positive] errno values with literal -E... ones) - properly format output - don''t use leading zeros in decimal output - move printing of average frequency into P-state conditional (rather than a C-state one) - don''t print some C-state related info when CPU idle management is disabled in the hypervisor - use calloc() for array

ging_prep ensures that an mfn is backing the paged-out gfn, and transitions to the next state in the paging state machine for this page. Foreign mappings of the gfn will now succeed. This is the key idea, as it allows the pager to now map the gfn and fill in its contents. Unfortunately, it also allows any other foreign mapper to map the gfn and read its contents. This is particularly dangerous

Hi everyone, When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE to y then I cannot boot Xen; there is a crash. If I turn CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has booted, xenpm works and gives some sane output, see below. I have tested this with kernels 3.2 to 3.4.6. Is it impossible to use INTEL_IDLE with Xen? If this is a known issue then maybe

Returns free memory size per node in "xm info". This info can help users who want to bind their guest domain in one node of their NUMA machines thought set CPU affinity. I also write IA64 part support which I would send to XEN-IA64 mail-list. Thanks. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

From: Ian Campbell <ian.campbell@citrix.com> There are many hypercalls which make no sense or which are not supported on ARM systems but it''s not all that obvious which ones we do support. So lets try and document the hypercalls which are useful on ARM. I''m not sure this is the best way to go about this, I''m open to other ideas. Signed-off-by: Ian Campbell

Testing on an 8-node 128-way NUMA machine has exposed a problem with Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized CPUs at 32, the machine appears to have 16 CPUs on the first and second nodes and none on the remaining nodes. Given this asymmetry, the calculation of sockets_per_node (which is later used to calculate nr_cpus) is incorrect:

Hi Jan, After commit 2ca9fbd739b8a72b16dd790d0fff7b75f5488fb8 AMD IOMMU: allocate IRTE entries instead of using a static mapping, booting dom0 stalls several times. Sometimes this results in RCU stall warnings from the dom0 kernel, hitting the "any" key, on normal or serial console, makes the boot continue for a while but it stalls several times. (It also stalls on shutdown BTW) I have

Hi all, this patch series makes the necessary changes to make sure that the current ARM hypercall ABI can be used as-is on 64 bit ARM platforms: - it defines xen_ulong_t as uint64_t on ARM; - it introduces a new macro to handle guest pointers, called XEN_GUEST_HANDLE_PARAM (that has size 4 bytes on aarch and is going to have size 8 bytes on aarch64); - it replaces all the occurrences of

This is a fourth cut of the hypervisor patch of the proposed XENMEM_claim_pages hypercall/subop, taking into account feedback from Jan and Keir and IanC, plus some fixes found via runtime debugging (using privcmd only) and some added comments/cleanup. [Logistical note: I will be out tomorrow (Friday) plus US holidays next week so my responsiveness to comments may be slower for awhile. --djm]

Hi, I'm trying to get standard errors for some of the variables in my data frame. One of the questions on my survey is whether faculty coordinate across curriculum to include Arts Education as subject matter. All the responses are coded in zeros and ones obviously. For some of the other variables I have a 2 for those that responded with "Don't Know". I'm getting NA for

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

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

Specifically, what values are or aren''t accepted as CPU identifier, and how the values get interpreted should be consistent across sub-commands (intended behavior now: non-negative values are okay, and along with omitting the argument, specifying "all" will also be accepted). For error handling, error messages should get consistently issued to stderr, and the tool should now
