I'm a little lost (and admit that I'm pretty green to all this). I am looking for the drivers for the M.2 drivers for RHEL/CentOS 8 on x86_64 architecture. Previously I was successful installing the drivers under Ubuntu following the Getting Started guide on the Coral website (https://coral.ai/docs/m2/get-started). But I need to run CentOS 8 for other reasons. So I know that the board works. I know it can be supported in Linux, but don't know how to convert the instructions for CentOS.
My M.2 board is connected to my server using a M.2 to PCIe adapter.
Thanks in advance!

I also believe that you should be able to get this working.
Couple things that you'll need:
libedgetpu.so - You can download the latest runtime from here: https://github.com/google-coral/edgetpu/tree/master/libedgetpu/direct/k8
apex/gasket modules - This is a required kernel module for talking to the pcie module. This is going to be very tricky, first you'll need to make sure that you don't already have apex/gasket module already installed. If you do, blacklist it and load our modules. Now our modules cannot be installed with apt-get since you are in centos, so your only option is to download the code from source and compile it on your own: https://coral.googlesource.com/linux-imx/+/refs/heads/release-day/drivers/staging/gasket

I am new user to the Raspberry Pi 3.
How much space is required to install OpenCV on Raspberry?
For my with my Raspberry Pi 3B+ / Raspberry Pi 4b a 8gb sd-card was too small. I would recommend at least 16gb. But I really depends on which version and which operating system you use (pitop, twister os, raspbian, raspberry pi os...). Maybe you should try running your pi with a USB-flashdrive or a small ssd?
Installing OpenCV on your Raspberry Pi can be done in two ways, both having different space requirements:
You can use the Debian repositories with the sudo apt-get install libopencv-dev command. This is the easiest way to install OpenCV on your Pi, and also takes the least amount of space (if that's a concern for you). It will take around 80M when installed. The downsides of this approach is that you get OpenCV 2.4.9., there isn't and upgrade to OpenCV 3.0 yet. Also you can't customize the installation.
The second and more difficult option is to compile the sources yourself. To compile the code you will need more than 4GB of disk space as the compiled code takes a lot more space. However the installed libraries (.lib) are under a 100M. If you want to use this option I recommend you to connect a USB stick or external HDD to your Pi. Use the USB or HDD (with more than 4GB of free space) to compile and build OpenCV. After installing OpenCV you can delete this directory again as you only need the library files (of course, this changes when you actually want to develop code on your Pi).
Mmmm... how long is a piece of string?
It depends on what/how you install and what/how you count. The following factors, and others, will affect the answer:
debug or release versions
examples installed or not
documentation installed or not
contrib code installed or not
It also depends on whether you count the fact that to build it, you will need a compiler and all its associated stuff, cmake and a bunch of V4L, video formats and image formats and libraries.
Also, you can build it and install it and then delete the source yet continue to use the product.
FWIW, my build area on a Raspberry Pi amounts to 2.1GB - that is the source and a release build without contrib.
Opencv takes around 5.5 gigabytes of space on your sd card.
From experience I used a 64gb card with raspbian lite on it. I recommend you use a 32 gb or higher disc for your projects. Just know that when you are going to install a lot of packages for your future projects, you will run out of space. Under 32 might work but it is not recommended. Here is a tip: install the latest opencv version on your raspberry pi.
Here is a tutorial which I have personally followed which works. https://linuxize.com/post/how-to-install-opencv-on-raspberry-pi/
I deleted my Linux install and recently tried OpenBSD but i am not sure how to set up a GUI environment and xserver. I have a R9 290 gpu and I saw that it should be supported by the radeon driver however I don't know how to download or configure it.
thank you.
All drivers are included in the default install and should Just Work©. That said, your Radeon GPU may need firmware whose license prevents OpenBSD from including it. Running fw_update should install it if it's needed.
Other than that, you just need to configure X. Everything's included in the base system, including the window managers cwm and fvwm. If you want another, you can install it from ports. To configure X, read the very well-written FAQ entry.
Enjoy!
Torch is a scientific computing framework with wide support for machine learning algorithms. It is easy to use and efficient, thanks to an easy and fast scripting language, LuaJIT, and an underlying C/CUDA implementation.
Q:
Is there a way to install torch on MS Windows 8.1?
I got it installed and running on Windows (although not 8.1, but I don't expect the process to be different) following instructions in this repository; it's now deprecated, but wasn't deprecated few months ago when I built it. The new instructions point to torch/torch7 repository, but it has a different structure and I haven't been able to build it on Windows yet.
There are instructions on how to install Torch7 from luarocks, but you may run into issues on windows as well; I haven't tried this process. It seems like there is no official support for Windows yet, but some work is being done by contributors (there is a link to a pull request in that thread).
Based on my experience, compiling that deprecated repo may be your best option on Windows at the moment.
Update (7/9/2015): I've recently submitted several changes that fix compilation issues with mingw, so you may try the most recent version of torch7 and follow the build instructions in the ticket. Note that the changes only apply to the core lib and additional libraries may need similar changes.
This webpage hosted by New York University recommends installing a Linux virtual machine in order to run Torch7 on Windows through Linux. Another option would off course be to install a Linux dist in parallel with Windows 8.
Otherwise, if you don't mind running an older version of Torch, there is a Windows installer for Torch5 at SourceForge.
I think to use a GPU from inside the virtual machine, the processor and the motherboard should not only support VT-x , but VT-d should be supported too.
But the question is, if I use a CPU with VT-d supported, do you think there will be a significant loss in PCIe connections efficiency?
From what I understand,
VT-d is important if I want to give the virtual machines direct access to my hardware components (like PCI Express cards). Like directly attach graphics card to vm instead of host machine. Isn't that mean that the PCIe connections efficiency will be the same just like if it was the host?
I want to set-up vicidial in my local computer server any information or a document for that?
I googled but I can't find exact resource.
I googled below links.

Thanks in advance.
Vicidial is an Open Source Predictive AutoDialer based on Asterisk with PHP/MySQL/Perl coding.
Installation of Vicidial is only viable on a Linux machine.
There are several locations with Scratch Install instructions for Ubuntu and CentOS. In fact, the Vicidial Wiki has a list of a few of them: http://wiki.vicidial.org/index.php/VICI:Installation
Most are quite old except for the Goautodial.com which has instructions for CentOS installation by adding the goautodial repositories and then just upgrading the OS to get all the necessary packages.
If you're not using CentOS or Ubuntu and none of those instructions work for your purpose, beware that Vicidial installation is not easy. It is MUCH better to dedicate a machine to the purpose by installing from Vicibox.com's .iso image which will wipe the computer clean. The installation becomes easy and then you need only argue with configuration.
If you can not dedicate a machine to this purpose, you should take the earlier suggestion of a Virtual server (vSphere or Virtualbox both work for Vicibox.com's .iso installer), but beware that you'll only be able to have one or two agents on the virtual dialer at the most. Luckily, if you do get the virtual vicidial working, it is possible to backup the virtual server's database and install it on a hardware based server later to bring everything with you without having to do it all over.
I have a toshiba laptop c850, dual core. Toshiba does not provide any driver for Wi-Fi for Ubuntu 12.10. I am currently having problem in using DSL modem, Ethernet and Wi-Fi. Can anyone tell me the solution to this problem?
maybe you will find some information there :

Wireless
A really up to date kernel is required for wireless support, at least
3.5.0 is recommended. Realtek has the Linux drivers available for download but they must be re-complied after upgrades to kernel.
As you commented, you got the Atheros Communications Inc. AR8162 Fast Ethernet Controller.
This is some guesswork here because there are several versions of the driver and some people state only one is working for them, I stick with the most popular for now.
First download this file from another machine:
https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5-u.tar.bz2
If you have Ubuntu or another Linux distro on your second machine you can use wget to download the file:
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5-u.tar.bz2
Next, use your preferred method (preferably an USB Drive) to copy it to your target machine (Toshiba C850) and use the following commands in a terminal. Make sure you are in the right directory first and use cd to change to the directory where your downloaded file resides.
tar -xzvf compat-drivers-2013-03-28-5-u.tar.bz2
cd compat-drivers-2013-03-28-5-u
./scripts/driver-select alx
make
sudo make install
sudo modprobe alx
If this doesn't work try a reboot first then you can try one of the other versions, I can't tell which will work for you:
http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2012-02-28-p.tar.bz2
https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/04/compat-drivers-2013-03-04-u.tar.bz2
