kandi X-RAY | kernel Summary
these are the release notes for linux version 4. read them carefully, as they tell you what this is all about, explain how to install the kernel, and what to do if something goes wrong. linux is a clone of the operating system unix, written from scratch by linus torvalds with assistance from a loosely-knit team of hackers across the net. it aims towards posix and single unix specification compliance. it has all the features you would expect in a modern fully-fledged unix, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and multistack networking including ipv4 and ipv6. it is distributed under the gnu general public license - see the accompanying copying file for more details. on what hardware does it run?. although originally developed first for

QUESTION
I am trying to write the following C code in Metal Shading Language inside of a kernel void function:

Answered 2021-Jun-15 at 21:02Don't know about metal specifically, but in ordinary C, you'd want to put f and byteArray inside a union

QUESTION
I tried 5 different implementations of the Sobel operator in Python, one of which I implemented myself, and the results are radically different.
My questions is similar to this one, but there are still differences I don't understand with the other implementations.
Is there any agreed on definition of the Sobel operator, and is it always synonymous to "image gradient"?
Even the definition of the Sobel kernel is different from source to source, according to Wikipedia it is [[1, 0, -1],[2, 0, -2],[1, 0, -1]], but according to other sources it is [[-1, 0, 1],[-2, 0, 2],[-1, 0, 1]].
Here is my code where I tried the different techniques:
...ANSWER
Answered 2021-Jun-15 at 14:22according to wikipedia it's [[1, 0, -1],[2, 0, -2],[1, 0, 1]] but according to other sources it's [[-1, 0, 1],[-2, 0, 2],[-1, 0, 1]]
Both are used for detecting vertical edges. Difference here is how these kernels mark "left" and "right" edges.
For simplicity sake lets consider 1D example, and let array be
[0, 0, 255, 255, 255]
then if we calculate using padding then
- kernel
[2, 0, -2]gives[0, -510, -510, 0, 0] - kernel
[-2, 0, 2]gives[0, 510, 510, 0, 0]
As you can see abrupt increase in value was marked with negative values by first kernel and positive values by second. Note that is is relevant only if you need to discriminate left vs right edges, when you want just to find vertical edges, you might use any of these 2 aboves and then get absolute value.
QUESTION
I have Windows 10 Pro Version 21H1 Build 19043.1052.
I have followed the guide in https://docs.microsoft.com/en-gb/windows/wsl/install-win10#step-4---download-the-linux-kernel-update-package and in Win 10 WSL won't set default 2 to get wsl. And I want to upgrade to version 2. I installed the regular Ubuntu from the Microsoft app store. And I did wsl --setdefault Ubuntu followed by wsl --set-default-version 2 and it only gave me For information on key differences with WSL 2 please visit https://aka.ms/wsl2. But wsl -l -v was still showing VERSION 1.
So I went an installed Ubuntu-20.04 LTS and now that version is showing VERSION 2 but not the regular Ubuntu one.
How can I get them both to version 2?
...ANSWER
Answered 2021-Jun-15 at 15:47When you do --set-default-version, you're setting the version for future distributions that you install. That doesn't convert or change any current distros you have installed. So for your existing Ubuntu distro that is version 1, you should use the wsl --set-version command to convert it to version 2 or revert back to version 1.

QUESTION
So far I have written programs where a kernel is called only once in the program
So I have a kernel
...ANSWER
Answered 2021-Jun-15 at 12:37Additional synchronization would not be necessary in this case for at least 2 reasons.
cudaMemcpyis a synchronizing call already. It blocks the CPU thread and waits until all previous CUDA activity issued to that device is complete, before it allows the data transfer to begin. Once the data transfer is complete, the CPU thread is allowed to proceed.CUDA activity issued to a single device will not overlap in any way unless using CUDA streams. You are not using streams. Therefore even asynchronous work issued to the device will execute in issue order. Item A and B issued to the device in that order will not overlap with each other. Item A will complete before item B is allowed to begin. This is a principal CUDA streams semantic point.

I'd like to run a simple neural network model which uses Keras on a Rasperry microcontroller. I get a problem when I use a layer. The code is defined like this:

Answered 2021-May-25 at 01:08I had the same problem, man. I want to transplant tflite to the development board of CEVA. There is no problem in compiling. In the process of running, there is also an error in AddBuiltin(full_connect). At present, the only possible situation I guess is that some devices can not support tflite.
QUESTION
I'm looking for a method to send data from userspace to bpf program in Linux.
I use libbpf in userspace and bpf_helpers in bpf program in kernel.
I now can send data from kernel to user by ringbuf and other.
but I want to use stack and queue for this. I can't find function that handles queue or stack in userspace and I still confused.
My question is: how can I send data from userspace to bpf program using stack or queue and get it in my bpf program, as what we do in bcc with bpf['queue'].push in userspace for example and queue.peek(&val); in bpf program.
thank you for any help!
...ANSWER
Answered 2021-Jun-15 at 07:42You should use the usual bpf_map_update_elem and bpf_map_lookup_elem functions for BPF_MAP_TYPE_QUEUE and BPF_MAP_TYPE_STACK maps.
You can find several examples in the kernel source code:

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too.

Answered 2021-Jun-12 at 01:50Your problem is that you have set SESSION_CONNECTION=session, but your SESSION_DRIVER=default, so you have to use SESSION_DRIVER=database in your .env. See the config/session.php:

I am digging deeper to kubernetes architecture, in all Kubernetes clusters on-premises/Cloud the master nodes a.k.a control planes needs to be Linux kernels but I can't find why?
...ANSWER
Answered 2021-Jun-13 at 19:22There isn't really a good reason other than we don't bother testing the control plane on Windows. In theory it's all just Go daemons that should compile fine on Windows but you would be on your own if any problems arise.
QUESTION
I can't compile DPDK inside a docker container, running under WSL2 as VM (and windows 10 as the host machine).
Background
Trying to compile DPDK locally inside a wsl-container some DPDK lib that used to be built on remote native linux machines.
The Dockerfile running the compilation had installed kernel headers, GNU toolchain and other various dependencies. The distribution is CentOS7.
The containers are managed by Docker Desktop
Versions are useless information here.
The Problem
Similar problems across DPDK versions.
In DPDK 20.11, using the meason build-system, the file kernel/linux/meason.build:
../kernel/linux/meson.build:23:1: ERROR: Problem encountered: Cannot compile kernel modules as requested - are kernel headers installed?
If I compile different DPDK versions of DPDK or building using other build-systems (makefiles), I am getting variants of the same error.
...ANSWER
Answered 2021-Jun-11 at 19:36Inside your /lib/modules has no entry with WSL2 "uname -r" output
Although WSL2 has /lib/modules/5.4.72-microsoft-standard-WSL2 (as a softlink), this soft link does not appear in the container.
