similar to: [PATCH] xen: arm32: Use system wide TLB flushes, not just inner-shareable

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.

First off, Apologies for the massive patch series... This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8 (AArch64) model. The kernel is the same one as I am currently using with the 32 bit hypervisor I haven''t yet tried starting a guest or anything super advanced like that ;-). Also there is not real support for 64-bit domains at all, although in one or two places I

Hello, This is the second version of this patch series. I only implement the VPF context switch support for arm32 and add dummy function to avoid compilation on arm64. I have switched the order of the patch because the old second one can be applied alone and the patch are cleaner :). For all the changes see each patch. Cheers, Julien Grall (2): xen/arm: don''t enable VFP on XEN

Hello, I am trying to boot Arndale board with Julien''s new XenARM patch series. But I have got "Data Abort" while in booting. My environment is: - Arndale Board - Xen-4.3-unstable from branch "arm" in git://xenbits.xen.org/people/julieng/xen-unstable.git - Dom0 Kernel from branch "dev-arndale-dom0-3.9" in

Hello everyone, this is the very first version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See

Add hypercall (shadow op: enable/disable and clean/peek dirtied page bitmap). It consists of two parts: dirty page detecting and saving. For detecting, we setup the guest p2m''s leaf PTE read-only and whenever the guest tries to write something, permission fault happens and traps into xen. The permission-faulted GPA should be saved for the toolstack (when it wants to see which pages

Dear All: I am pretty new to xen-devel, please correct me in the following. Assume we have the following terms GPT: guest page table SPT: shadow page table (Question a) When guest OS is running, is it always using SPT for address translation? If it is the case, how does guest OS refer and modify its own GPT content? It seems that there is a page table entry in SPT for the GPT page. (Question

The VMID field is 8 bits. Rather than allowing only up to 256 VMs per host reboot before things start "acting strange" instead maintain a simple bitmap of used VMIDs and allocate them statically to guests upon creation. This limits us to 256 concurrent VMs which is a reasonable improvement. Eventually we will want a proper scheme to allocate VMIDs on context switch. The existing code

Commit aa9e0057b19e29f76c9a81f9aebeeb1cb5bf1fdb made the libvirt backend use <shareable/> for the disk of the appliance, since at that time all the instances were using the disk directly. OTOH, commit 3ad44c866042919374e2d840502e53da2ed8aef0 switched to overlays for read-only disks, including the appliance, so effectively protecting the appliance. Because of this, the libvirt backend does

Hi I just wondered if there was a reason why Rails controller specs are not shareable? eg describe "All XHR POSTs to /gap/calculate_quote", :shared => true do controller_name :gap # ... end describe "XHR POST /gap/calculate_quote with valid details" do it_should_behave_like "All XHR POSTs to /gap/calculate_quote" # ... end blows up with

Yes, those two patches are fundamental to make XRay work on ARM. Backporting makes sense. We already added XRay on both ARM and AArch64 release notes, so they have to work. :) --renato

I think this is the last of the header fixes I''ve run across. Though it''s sometimes difficult to tell, I believe Xen/ia64 has asm/mm.h, flushtlb.h, page.h, and shadow.h. Please apply. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> -- Hollis Blanchard IBM Linux Technology Center

This patch series implements SMP boot for arch/arm, as far as getting all CPUs up and running the idle loop. Changes from v1: - moved barriers out of loop in udelay() - dropped broken GIC change in favour of explanatory comment - made the increment of ready_cpus atomic (I couldn''t move the increment to before signalling the next CPU because the PT switch has to happen between

Sorry, I initially included LLVM-Commits rather than LLVM-Dev. Fixed.

Hello Kindred R Spirits... I'm trying to get a file (csv) from Dropbox using their shareable link concept. They issue a short URL that goes to a web page where you see a button that says "Download File". They don't really give you the URL of the file itself, just this page. Is there a way to coax R into getting such a file? I don't even really want the file per

How is XRay tested? IIRC, Renato didn't see any test failures on ARM? Merging sounds reasonbaly, I'd just like to understand what's the risk for the branch.

I see. Thanks for clarifying. I'm Ok with merging these if Dean agrees, as I believe he's the code owner.

Hi Linus, Here's a set of patches to update paravirt_ops and Xen for 2.6.24 A quick overview of the patchset: paravirt_ops: Remove the monolithic paravirt_ops structure, and replace it with smaller structures of related functions. Also, clean up the handling of lazy mode to make it easier to implement. x86/mm/init.c: remove a chunk of dead code Xen: - remove duplicate includes -
