PowerPC Family Pedigree Detailed

With the development of PowerPC, the use of PowerPC architecture of the processor has formed a huge family, in communications, industrial control, aerospace defense and other requirements of high-performance and high reliability of the field has been widely used, is a "noble chip." At present, there are few Chinese materials to elaborate the PowerPC family pedigr

PowerPC Device Tree DTS detailed

Original address: http://blog.chinaunix.net/uid-26675482-id-3358038.html Abstract: The introduction of the device tree reduces the changes required by the kernel to support new hardware, improves code reuse, accelerates the development of Linux support packages, and enables a single kernel image to support multiple systems. As a dynamic between the U-boot and the Linux kernelInterface, this paper describes the data storage format of the device tree and the source code description syntax, and the

Summary of PowerPC PCI-E debugging

Recently, a FPGA was added to the PowerPC board, and the PCI-e was debugged when a PCI-E was used to connect the board. Since VxWorks itself has already written the driver, it can be called directly during use, but soon the problem arises: at first, the MMAP method was directly used to map the FPGA bus to the application's memory space and try to read and write. This method is relatively simple and does not need to be copied between the kernel and the

Brief Introduction to powerpc

Advantages of PowerPC over arm: With its outstanding performance and high integration and advanced technology, PowerPC chips are used in network communication applications, industrial control applications, home digitalization, network storage, military fields, power System Control is widely used. because PowerPC is cheaper than arm devices Tools are pirated every

Linux PowerPC interruption Principle Analysis

Before learning about the Interrupt Processing Mechanism, let's take a look at the interrupt source of PowerPC. Here we use the e300c3 kernel. From the perspective of the e300 core, the interrupt source can be divided into exceptions and external interruptions, exceptions are generated by the e300 kernel, such as illegal commands or TLB Miss during memory access. This situation is too complicated. If we do not go into the details, the interruptions me

PowerPC-based Linux kernel tour: 2nd station-_ secondary_start (start_here)-bottom

This section describes part of the PowerPC-based second-stage Linux Startup Process. MMU initialization involves a large amount of content and a large amount of code. This section continues to describe the MMU hardware initialization and final MMU enabling process. Before getting started, I first pointed out an error in the previous article. When I introduced the RFI instruction in the mmu_off function, I thought it was an interrupted return, but then

PowerPC ppc460-s MMU (six Shadow TLB)

Attention:Some operations may not cause the hardware to automatically perform contextual synchronization. For example, when we pass the tlbwe directiveWhen updating the Utlb page table, the hardware does not automatically perform contextual synchronization, that is, the shadow register is not automatically invalidatedCache (if there is a page table in the shadow cache that has already been invalidated, if there is a newMay cause an unknown problem); If you want to make the update

PowerPC uboot link Script Big makeover

key function are debugged according to the Uboot initiation process. Ensure that the uboot normally starts into the command line.(3) separate debugging for each module driver. So I modify the boards.cfg, modify the configuration file, determine the first address of the code snippet, memory header address and other basic elements. Expectations can be directly compiled. But after looking at the link script for the ppc460s processor, I think the problem is a little more complicated than I thought

A variety of Linux distributions quietly give up support PowerPC __linux

Linux has always been very good at hardware support, many of the old and all because of the Linux can be supported by the Linux operating system. However, the author recently learned that due to the user community and the frequency of the relationship of multiple Linux distributions have begun to quietly give up support PowerPC. As a result, PowerPC users will lose support for the latest mainstream Linux (p

How to port a PowerPC-Based Kernel

DTS configuration for PCI bus of PowerPC

During this period of time, we need to get the debugging and driver development work related to PCI Express. The old rule is that we should first look for information on the Internet. This kind of stuff is quite rare and we have already bought a book, I plan to summarize it by myself. This article describes how to configure the PCI bus in PowerPC. PowerPC uses a mechanism called FDT flat device description

Configuration space of PCI and PCI-E devices in PowerPC

PCI bus specifies the bus transaction that accesses the configuration space, which is called the configuration read/write transaction. Unlike the storage access transactions that use the storage address for access, the idnumber is used for addressing access to the PCI configuration space. The ID of a PCI device consists of the bus number, device number, and function number. For Embedded PowerPC applications, the PCI design is often very simple. The PC

Workshop for Embedded Linux development on powerpc

Recently, the boss asked me to introduce the experience of BSP development at the weekly meeting.Because there are foreigners in the group, they must also speak English.It's a great opportunity to practice English.It is expected to be an hour and a half, but I always want to talk more about it. Otherwise, how can I make it clear that BSP is so advanced in more than an hour?This is the first time I have worked on a workshop in the group, so I have paid more attention to preparing for it for a few
