Pay attention to the Shared_XXX pages and the corresponding address ranges. In terms of code, there are a few simple XV6 extensions to support copy-on-write. A simple google search might be enough.

Exactly what it says on the tin. It runs on Qemu’s RISC-V target. xv6 implements a minimal Unix file system interface. xv6 doesn't pay attention to file system layout. It overlaps computation and I/O, but doesn't do any disk scheduling. Its cache is write-through, which simplifies keeping on disk data structures consistent, but is bad for performance. Oct 19, 2018 · Memory utilization – One of the most common causes of web application latency is when most or all available physical memory (RAM) has been consumed on the host EC2 instance. CPU utilization – High CPU utilization on the host EC2 instance can significantly degrade web application performance and in some cases cause a server crash. Supporting multiple threads per process means that you will have to think about handling shared resources information. For example: growproc is a function in proc.c which is responsible for retrieving more memory when the process asks for it. If not protected, 2 running threads of the same process Git-2.14.2-64-bit.exe .

xv6 machine problem 1: Adding a system call Objectives. In this first xv6 assignment you will be modifying and adding code to a number of different files that implement the kernel. Along the way you'll learn how to build the kernel and test/debug your work, and will hopefully acquire a working knowledge of some essential kernel tasks and modules.

To become familiar with Unix-style forking and x86 memory management, you will convert the simple fork() implementation in xv6 to a copy-on-write fork(). This will involve writing a trap handler for page faults, augmenting the physical memory management code, and, of course, manipulating page tables.

REST API¶. The Solution Manager provides a REST API to perform programmatically certain tasks. This is useful to automate the creating and deployment of revisions, automate the management of the licenses, etc.

Shared peripheral interrupts – Numbering 60 in total, these interrupts can come from the I/O peripherals, or to and from the programmable logic (PL) side of the device. They are shared between the Zynq SoC’s two CPUs. Private peripheral interrupts – The five interrupts in this category are private to each

In MMIO, a portion of physical memory is hardwired to the registers of some I/O devices, so the same load/store instructions typically used to access memory can be used to access device registers. You’ve already seen one IO hole at physical address 0xA0000 (we use this to write to the VGA display buffer).

Implement a shared-memory fork() called sfork(). This version should have the parent and child share all their memory pages (so writes in one environment appear in the other) except for pages in the stack area, which should be treated in the usual copy-on-write manner.
