由于本身设备是通过直接内存访问DMA(Direct Memory Access)技术来实现数据传输的,CPU 只需要给出要传输哪些内容,放在哪段物理内存上面,把请求告诉设备,设备后面的操作就会利用 DMA 而不经过 CPU 直接传输,在传输结束之后,会通过中断请求 IRQ(Interrupt ReQuest)技术沿着设备树把"我做完了"这个信息告诉 CPU,CPU 会作为...

When reading from a file, the file system needs to traverse the entire path, visiting each inode along the way until reaching the inode for the desired file. Assuming the user has permission to access the file, the file system consults which blocks are associated with it and then read the...

Catfs is a caching filesystem written in Rust. Overview Catfs allows you to have cached access to another (possibly remote) filesystem. Caching semantic is read-ahead and write-through (seeCurrent Status). Currently it only provides a data cache and all metadata operations hit the source file...

A VDFS (virtual distributed filesystem) is a filesystem designed to work across a variety of storage layers. With a uniform API to manipulate and access content across many devices, VDFS is not restricted to a single machine. It achieves this by maintaining a virtual index of all storage loc...

So to retrieve the underlying socket buffer, we can simply offset the custom type and access the remaining bytes. Here we are, we have a way to attach eBPF program to TC and retrieve socket buffers to user space. The funny work can start! PerfEventArray是个环形缓冲区(ring buffer)并且...
