Hi All, I vaguely remember someone at Astricon making the case for having multiple containers/vps each running asterisk vs using asterisk direct on bare metal. Something about getting better performance. Does anyone have any insight on this? TIA and stay safe Dovid PS I know vps != containers I just don’t recall if the argument was for vps, containers or both instead of installing direct on

Andrew, Stephan Thanks for your help. Well, I really don?t have the choice of the interface it has to be CAN. My malloc is working but it may have some bug. I?m going to check the use of the CCRAM with an implementation of opus_alloc/opus_free. I will let you know how it works. Regards.

I''ve been trying to compare memory access speed between bare-metal, xen-pv and xen-pvhvm (hvm with pv drivers). In all 3 setups I''m running the same kernel (3.6.6), built with support for xen, on a 64 core AMD Opteron 6378. The output of xm info (relevant parts): machine : x86_64 nr_cpus : 64 nr_nodes : 8 cores_per_socket : 16

I'm running libvirt under Fedora 28. I would like to attach a USB device to a VM, but when I select "Redirect USB Device" from the "Virtual Machine" menu in virt-manager and then select the device, I get the error: USB redirection error spice-client-error-quark: Could not redirect [device name] at 1-11: Error setting USB device node ACL: 'Not authorized' (0)

hi, i am new to xen. pls. guide me what is best os should be used with xen. also let me know if there is any baremetal xen hypervisor available as i read that i require one OS on which xen hypervisor will be installed. want to use it with 32 bit machine. thanks for your help. -- With Best Wishes Balwant _______________________________________________ Xen-users mailing list

Hi all! I'm a "nervous nellie", I have not yet updated my 7.5 desktop to 7.6 because (1) it has an Nvidia card, and (2) I've heard of problems upgrading on top of software RAID (using RAID1 with 2 drives). I need to upgrade it to stay secure, and I want to do a bare-metal backup first (so I can put it all back as it now is, in case it explodes in my face), so I'm trying to

Hello to all: I know this list is generally Linux-only, but I figured I'd try to gain wisdom from those with hard-core Windows needs, too. I was recently pricing out a high-end desktop system for a user who will doing a lot of CAD, Matlab, SolidWorks, and other apps that will utilize a lot of number crunching and video. The quote for the desktop (64-bit Vista is likely), which included 12

Hi everyone, I?m currently trying to use opus on a ST ARM (STM32F407) without any OS (bare metal). The aim of my project is to transmit voice over CAN bus. The main issue I have is that opus fail to allocate memory, the ALLOC macro always return a NULL pointer. I have sure that I have enough free space to allocate buffers. Is there anyone who already try this or have meet this issue ? Thanks

Hi, We're working on adding exception handling support for a downstream bare-metal target. I read through the LLVM exception handling docs [1] and went through some patches from other backends to understand what parts we need to implement. We're now at a point were it feels like it should work, but unfortunately exceptions are still not getting caught. Our target uses DWARF

Hi Tim. Thank you for taking to time to comment on the background! I will definitely study lldb and remote JIT for ideas.  I worry that I will not be able to pre-link on the host side because the host cannot(?) know the final memory layout of code on the client side, especially when there are multiple plugins being loaded in different combinations on the host and client.  Is that an

Is there a documented approach somewhere for performing an unattended ''bare metal'' install of Xen? The Xen Users'' Manual describes an installation flow that requires a host OS on the target machine. This host OS is used for installation of Xen, but Xen does not execute "on top of" this OS (rather Xen executes directly "on top of" the hardware

Hello! Q1 Are there any resources or examples on embedding LLVM into an ARM-based bare-metal application?  Searching in this area only turns up information on how to use LLVM to target bare-metal when I want to compile LLVM for linking against a bare-metal application. Q2 Are there any memory usage benchmarks for LLVM across the common tasks (especially loading bytecode, doing the

Would you say that embedding the LLVM linker is a practical way to get the required dynamic linking capabilities on the bare-metal side?

Hi Peter Thank you for your helpful comments, especially on the RPI.  Since my use case is lot simpler than compiling all of Clang, I hopefully can take your experience as a good sign. The RTOS that TI provides for the AM335x actually has pretty complete posix layer and other standard libraries.  However, I am working without any virtual memory subsystem, so no mmap.  However, I was under

Hi, I was wondering if there is any documentation on how to write a bare metal application for Xen. I don''t need to parse the device tree and such yet, a simple booting "Hello World" would be fine :-) We wrote one and when trying to boot we get ( this was an uncompressed binary, no image): libxl: notice: libxl_numa.c:451:libxl__get_numa_candidate: NUMA placement failed,
