linuxpcie驱动
① linux下pcie驱动开发，该看些什么资料
linux下pcie驱动开发大概可以分为4个阶段，水平从低到高：
从安装使用=>linux常用命令=>linux系统编程=>内核开发阅读内核源码
系统编程推荐《高级unix环境编程》；
还有《unix网络编程》；
内核开发阅读内核源码阶段，从写驱动入手逐渐深入linux内核开发
参考书如下：
1.《linux
device
drivers》
2.《linux
kernel
development》
3.《understading
the
linux
kernel》
4.《linux源码情景分析》
然后还需要看资料理解elf文件格式，连接器和加载器，cmu的一本教材中文名为《深入理解计算机系统》比较好。
② 求教高手，LINUX 系统下PCIE 驱动移植
这个移植还可以教，驱动开发是不可能的，底层的东西得自己找资料，自己钻研。应用还好搞，看看QT这方面的书。
③ linux下面pci设备驱动和pcie设备驱动的区别
PCI 设备上有三种地址空间： （1）PCI的I/O空间 （2）PCI的存储空间 （3）PCI的配置空间。 CPU可以访问PCI设备上的所有地址空间，其中I/O空间和存储空间提供给设备驱动程序使用，而配置空间则由Linux内核中的PCI初始化代码使用。内核在启动时负...
④ linux下pcie设备卡驱动问题
lspci就可以看到了
⑤ 装完linux系统重启不停地提示“pciehp.....”，怎么解决
未安装成功，需要重装。
⑥ 为啥PCIe卡被拔掉之后，lspci还能显示其被拔掉前的信息呢
更正一点，呵呵，我们不是直接将PCIe卡从插座上拔掉，是关掉了PCIe卡上面的电源开关，从而达到拔掉卡的效果。不知道这种方式和直接拔掉卡效果是否一样。另外，驱动是直接用的linux自带的PCIe驱动。我自己感觉/sys/和/proc里面的PCIe设备信息是系统在枚举PCIe设备的时候生成的，所以即使将PCIe卡去除，系统也会保留这些信息，除非通过某种方式（比如系统重启）让系统重新枚举PCIe设备。
⑦ LINUX系统下为什么PCIE网卡可用而PCI网卡不可用
和什么网卡没关系，正好你的Linux版本有PCIE网卡的驱动，你PCI网卡的驱动没有！~查下PCI网卡的驱动，经驱动程序安装上就可以了！~
⑧ linux如何打开pcie设备
跟pc上的pcie一样的一个总线而已啊，你有pcie设备的话插上你的板子上的pcie 插槽，就可以用了。当然你的系统中还得有pcie设备的驱动支持才行。
⑨ 安装linux 出现realtek pcie gbe family controller ser
Realtek PCIE GBE family controller这个是你的网卡驱动~~建议你重新安装一下网卡驱动。
安装Realtek驱动时建议不要使用最新版的驱动，而是选择稳定版本~
⑩ 在LINUX中如何加载驱动网卡
直接找好对应的驱动 一般都会有readme 或者install 之类的说明文档来告诉你如何去安装这个网卡驱动的
Linux* Base Driver for the Atheros(R) AR8121/AR8113 PCI-E Ethernet Adapter

In This Release
===============
This file describes the Linux* Base Driver for the Atheros(R) AR8121/AR8113 PCI-E
Ethernet Adapter, version 1.0.0.5 This driver supports the 2.4.x and 2.6.x kernels.
This driver is only supported as a loadable mole at this time. Atheros is not
supplying patches against the kernel source to allow for static linking of
the driver. For questions related to hardware requirements, refer to the
documentation supplied with your Atheros(R) adapter. All hardware
requirements listed apply to use with Linux.
Building and Installation
=========================
To build a binary RPM* package of this driver, run 'rpmbuild -tb
<filename.tar.gz>'. Replace <filename.tar.gz> with the specific filename of
the driver.
NOTE: For the build to work properly, the currently running kernel MUST match
the version and configuration of the installed kernel sources. If you
have just recompiled the kernel reboot the system now.
RPM functionality has only been tested in Red Hat distributions.
1. Move the base driver tar file to the directory of your choice. For example,
use /home/username/arl1e or /usr/local/src/arl1e.
2. Untar/unzip archive:
tar zxf arl1e-x.x.x.x.tar.gz
3. Change to the driver src directory:
cd arl1e-x.x.x.x/src/
4. Compile the driver mole:
make install
The binary will be installed as:
/lib/moles/<KERNEL VERSION>/kernel/drivers/net/arl1e.[k]o
The install locations listed above are the default locations. They might
not be correct for certain Linux distributions. For more information,
see the ldistrib.txt file included in the driver tar.
5. Install the mole:
insmod arl1e <parameter>=<value>
6. Assign an IP address to the interface by entering the following, where
x is the interface number:
ifconfig ethx <IP_address>
7. Verify that the interface works. Enter the following, where <IP_address>
is the IP address for another machine on the same subnet as the interface
that is being tested:
ping <IP_address>
Command Line Parameters
=======================
If the driver is built as a mole, the following optional parameters are
used by entering them on the command line with the modprobe or insmod command
using this syntax:
modprobe arl1e [<option>=<VAL1>,<VAL2>,...]
insmod arl1e [<option>=<VAL1>,<VAL2>,...]
For example, with two L001 PCIE adapters, entering:
insmod arl1e TxMemSize=80,128
loads the arl1e driver with 8KB TX memory for the first adapter and 10KB TX memory
for the second adapter.
The default value for each parameter is generally the recommended setting,
unless otherwise noted.
NOTES: A descriptor describes a data buffer and attributes related to the
data buffer. This information is accessed by the hardware.
media_type
Valid Range: 0-4
0 - auto-negotiate at all supported speeds
1 - only link at 1000Mbps Full Duplex
2 - only link at 100Mbps Full Duplex
3 - only link at 100Mbps Half Duplex
4 - only link at 10Mbps Full Duplex
5 - only link at 10Mbps Half Duplex
Default Value: 0
media_type forces the line speed/plex to the specified value in
megabits per second(Mbps). If this parameter is not specified or is set
to 0 and the link partner is set to auto-negotiate, the board will
auto-detect the correct speed.
int_mod_timer
Valid Range: 50-65000
Default Value: 100
This value represents the minmum interval between interrupts controller
generated.
RxMemBlock
Valid Range: 16-512
Default Value: 64
This value is the number of receice memory block allocated by the driver.
Increasing this value allows the driver to buffer more incoming packets.
Each memory block is 1536 bytes.
NOTE: Depending on the available system resources, the request for a
higher number of receive descriptors may be denied. In this case,
use a lower number.
TxMemSize
Valid Range: 4-64
Default Value: 8
This value is the number KB of transmit memory allocated by the driver.
Increasing this value allows the driver to queue more transmits.
NOTE: Depending on the available system resources, the request for a
higher number of transmit descriptors may be denied. In this case,
use a lower number.
FlashVendor
Valid Range: 0-2
Default Value: 0
This value standards on vendor of spi flash used by the adapter.
0 for Atmel, 1 for SST, 2 for ST
Additional Configurations
=========================
Configuring the Driver on Different Distributions
-------------------------------------------------
Configuring a network driver to load properly when the system is started is
distribution dependent. Typically, the configuration process involves adding
an alias line to /etc/moles.conf as well as editing other system startup
scripts and/or configuration files. Many popular Linux distributions ship
with tools to make these changes for you. To learn the proper way to
configure a network device for your system, refer to your distribution
documentation. If ring this process you are asked for the driver or mole
name, the name for the Linux Base Driver for the Atheros AR8121/AR8113 is arl1e
As an example, if you install the arl1e driver for two AR8121/AR8113 adapters
(eth0 and eth1) and set the speed and plex to 10full and 100half, add the
following to moles.conf:
alias eth0 arl1e
alias eth1 arl1e
options arl1e Speed=10,100 Duplex=2,1
Viewing Link Messages
---------------------
Link messages will not be displayed to the console if the distribution is
restricting system messages. In order to see network driver link messages
on your console, set dmesg to eight by entering the following:
dmesg -n 8
NOTE: This setting is not saved across reboots.
Known Issues
============
NOTE: For distribution-specific information, see the ldistrib.txt file
included in the driver tar.
Driver Compilation
------------------
When trying to compile the driver by running make install, the following
error may occur:
"Linux kernel source not configured - missing version.h"
To solve this issue, create the version.h file by going to the Linux source
tree and entering:
make include/linux/version.h.
