一个endpoint设备功能通过PCI Express Designated Vendor Specific Extended Capability(DVSEC)来报告支持Intel SIOV。系统软件和工具可以使用此能力来检测支持Intel SIOV的端点设备,而不依赖于host driver。host driver仍然负责通过系统软件特定接口启用Intel SIOV和相关操作。 本文主要参考:Intel Scalable I/O Virtualization ...
Although it may not directly resolve the issue, it is intended to address the problem encountered during the QAT installation driver, as indicated in the log below: Starting QAT service modprobe: ERROR: module 'intel_qat' is unsupported modprobe: ERROR: Use --allow-unsupporte...
and application processes. A shared virtual memory space allows the device to operate directly in the applications virtual address space without requiring pinned memory. Each instance of Intel DSA is exposed as a PCI-Express complex integrated endpoint and supports a variety of PCI-SIG...
编程简化:SVM 的 DMA 开发范式,用户态 malloc buffer、填 buffer、kick driver 发送数据即可。 3.2.2 DMA 重映射在 VMM 中的应用(虚拟化场景) 主要用来实现设备直通,克服纯软件模拟设备虚拟化的缺陷,见图 3。通过 DMA 重映射能力限制设备只能访问其所直通给的 VM 的内存。

When a PCIe root port detects an error, LER can shut down the PCIe link of the root port and then restore the link via OS/driver/UEFI-FW in a cycle. LER consists of two phases: error suppression and recovery. Error suppression phase: When a ro...
The supported Single-Root I/O Virtualization (SR-IOV) to Intel® Graphics Virtualization Technology and I/O Virtualization Technology (Intel® GVT) gives virtual machines (VMs) access to the physical functions of a GPU’s PCI Express port and reduces the latency caused by the entirely ...
