An OpenCAPI device can also host its own memory, that can be accessed from the host. OpenCAPI is known in linux as 'ocxl', as the open, processor-agnostic evolution of 'cxl' (the driver for the IBM CAPI interface for powerpc), which was named that way to avoid confusion with the ISDN CAPI subsystem. High-level view ===== OpenCAPI defines a Data Link. To address this situation, the userspace I/O system (UIO) was designed. For typical industrial I/O cards, only a very small kernel module is needed. The main part of the driver will run in user space. This simplifies development and reduces the risk of serious bugs within a kernel module

This crate contains bindgen-generated bindings for Linux's userspace API. This is primarily of interest if you want to make raw system calls directly, which is tedious and error prone and not necessary for most use cases. For a minimal type-safe, memory-safe, and I/O-safe API to the Linux system calls built on these bindings, see the posish crate eBPF Userspace API; IOCTLs; IOMMU Userspace API; Linux Media Infrastructure userspace API.

In my case, on the systems I happened to be checking, this was a symbolic link to /sys/firmware/devicetree/base IOMMU Userspace API¶ IOMMU UAPI is used for virtualization cases where communications are needed between physical and virtual IOMMU drivers. For baremetal usage, the IOMMU is a system device which does not need to communicate with userspace directly This API is also known as Linux DVB API. It it was originally written to support the European digital TV standard (DVB), and later extended to support all digital TV standards. In order to avoid confusion, within this document, it was opted to refer to it, and to associated hardware as Digital TV As a consequence this means: The Linux kernel's no regression policy holds in practice only for open-source userspace of the DRM subsystem. DRM developers are perfectly fine if closed-source blob drivers in userspace use the same uAPI as the open drivers, but they must do so in the exact same way as the open drivers Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.1 or any later version published by the Free Software Foundation.

  3. Overview. The term userland (or user space) refers to all code that runs outside the operating system's kernel. Userland usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc. . Each user space process normally runs in its own virtual memory.
  4. Linus Torvalds included patches into the mainline tree which implement a stable userspace driver API into the Linux kernel. The stable driver API was already announced a year ago by Greg Kroah-Hartman. Now the last patches where uploaded and the API was included in Linus' tree. The idea of the API is to make life easier for driver developers

See Userspace API for details. The difference between the paths for CPU and GPU addresses is in how the memory is pinned and unpinned. For CPU memory this is handled by built-in Linux Kernel functions (get_user_pages() and put_page()). However, in the GPU memory case the pinning and unpinning has to be handled by functions provided by the.

Linux and glibc API changes. As The Linux Programming Interface went to press in August 2010, it was up to date with the then current versions of the Linux kernel (2.6.35), glibc (2.12), and the POSIX.1/Single UNIX Standard (POSIX.1-2008/SUSv4). Because the developers of both the Linux kernel and glibc are committed to maintaining ABI compatibility, virtually all of the details provided in. This section deals with the Generic Netlink subsystem in the Linux kernel and provides a simple example of how in-kernel users can make use of the Generic Netlink API.

UIO: user-space drivers. [Posted May 2, 2007 by corbet] The concept of supporting user-space drivers has appeared on this page a few times before.

The interface has changed somewhat, so another look is called for Userspace RCU. liburcu is a LGPLv2.1 userspace RCU (read-copy-update) library. This data synchronization library provides read-side access which scales linearly with the number of cores. liburcu-cds provides efficient data structures based on RCU and lock-free algorithms.

Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag) To avoid this problem, userspace must have a way to request O_CLOEXEC flag be set when the dma-buf fd is created. So any API provided by the exporting driver to create a dmabuf fd must provide a way to let userspace control setting of O_CLOEXEC flag passed in to dma_buf_fd(). Memory mapping the contents of the DMA buffer is also supported Доклад Василия Хоружика на октябрьской линуксовке mlug 201
