pcie configuration space

There is a lot of information on the configuration space of the PCI device, the following figure is the 64-byte configuration space that the PCI device must support, the range is 0x00-0x3f.Many PCI devices only support 64 bytes of configuration

, configuration mechanism #1 is the only option to access the PCI configuration space. The RW software can read the mcfg base address: Figure 1 At the same time, we can also see the value of b0d2f0's register: Figure 2 then, based on the base address f8000000 and b0d2f0, according to The PCIe cofigration

Test environment: Ubuntu 14.04LTSUnder Windows, we can easily see all of the PCIe config space with rw everything, but we recently wanted to dump PCIe config space under Linux, first we tried to use IO read,That is, usually we will use CF8 and CFC way, but unfortunately this way can only read out 256 bytes, then the ba

alignment. So pay attention to byte sequence conversion. When the powercp processor reads int_ack, the host converts the read operation into a PCI bus to interrupt the response transaction. It is the configuration space of 64 bytes that the PCI device must support. The value range is 0x00-0x3f: Many PCI devices only support 64-byte configuration

select directory, select a directory to save the plug-in, and then finish. Then a new plugins directory will be generated under the directory you selected, which contains a jar file that replaces org in Eclipse/plugins. eclipse. jface. text_3.6.1.r361_v20100825-0800.jar (this file different versions of eclipse, the later version will be different, I use eclipse 3.6), so it is done! 9.

Linux PCI/PCI-E Device configuration space Read and modify 1 Preface PCI and PCI Express, is a high-speed bus commonly used by computers. PCI/PCI-E device drivers and operating system cores in the operating system require access to PCI and PCI-E configuration space. The normal operation of PCI/PCI-E equipment is inse

Since the introduction of PCI bus, its unique characteristics have been favored by many vendors, which has become the mainstream of computer extension bus. At present, many domestic technical personnel have the ability to develop PCI bus interface equipment. However, the PCI bus programming technology, that is, the operation of the PCI bus device technology, has been a technical staff to feel the headache of things. The core technology of PCI bus programming is to understand and access the corre

PCI device configuration space problems Generally speaking, there are two methods to implement the PCI bus interface: one is to use a programmable device CPLD or FPGA, and the other is to use a dedicated interface chip, like the PCI9054 of PLX, ch365. The two have their own advantages and disadvantages. When using programmable devices, you can optimize the interface logic based on specific needs to achiev
