-Openwrt wireless drivers use the open-source version wireless.kernel.org, backports.
-We use the open-source qdk version (the wireless driver is transplanted from the ralink driver ).
Summary of various problems encountered during the period:
1. UI problems, no station is displayed, channel cannot be set, encryption is added by ourselves.
2. Due to the ralink
Update new NIC driver, fix win7 ralink nic ralink RT3290 blue screen netr28x.sys drive file error when PC sleeps and boot NICMy laptop is win7, ralink Nic Ralink RT3290 802.11bgn Wi-Fi AdapterAfter testing did solve the blue screen problem, download the network card driver here, install the update: NIC driver version:
In ubuntu 10.04, if it is a ralink wireless network adapter, it may be connected to a wireless network that is not encrypted or TKIP, but cannot be connected to a CCMP wireless network. This is because the system's built-in rt2870sta driver has a bug. The system comes with the 2870sta and 3070sta drivers, so there are conflicts during loading. Therefore, you need to add other unused blacklist

Update to Rt3290sta.ko speed and stability are improved.There is several guides that speak of the same. Guides like this source, this source or the bug report mention some procedures to get this Wireless card working

Control program.In addition, routing and address resolution are handled by the kernel.
Loadable Modules
The features provided by the Linux kernel can be extended at run time, that is, when the system is up and running, we can add or remove functionality from the kernel to the kernel.Code that can be added to the kernel at run time is called a "module."The Linux kernel supports several types of modules, including but not limited to device drivers.Each module consists of target code
This is a 2014kdd, geographic location service paper.
Contents:
1) First, the author raised a valuable Question: recommend taxi drivers with routes that can be carried to the guests at the minimum cost.
2) Secondly, the novelty of the problem is that in the past, there were scattered recommendation points. This paper is a recommendation route. It can be said that the location service provided goes further.
3) then, two sub-problems are pointed out: a)
The stream device driver is actually the driver for exporting standard stream interface functions. This is the definition above. In wince, all stream devices export stream device interfaces, so that Device Manager in wince can load and manage these stream device drivers.

How to use the device tree of linux drivers and how to use the device tree of linux drivers
The Device Tree describes the hardware from the software perspective, and DTS is the Device Tree source file. DTC is responsible for converting DTS to DTB, and DTB is the binary form of DTS for machine use.
The Device Tree is a tree structure. Each child node except the root node has a unique parent node, which can h
device in the private_data member that represents the opened file pointer filp for other operation functions.
Release Operation:
int yjpLED_release(struct inode *inode, struct file *filp){filp->private_data = NULL;return 0;}
Release the content allocated by open in filp-> private_data.
Write operation:
ssize_t yjpLED_write(struct file *filp, const char __user *buf, size_t count, loff_t *f_pos){ssize_t retval;struct yjpLED *dev;dev = filp->private_data;if(down_interruptible(dev->sem))return -ERE
Poll for linux drivers and poll for linux driversPOLL operations
1. POLL execution process:
Poll is a system call. Its kernel entry function is sys_poll. sys_poll calls do_sys_poll directly without any processing. The execution process of do_sys_poll can be divided into three parts:
1. Copy the input pollfd array to the kernel space. Because the copy operation is related to the array length, this is an O (n) operation, in do_sys_poll, the code in this
This document describes how to use ctl_code to communicate with a Windows NT driver. generally, user-Mode Applications can communicate with kernel-mode drivers by calling createfile and deviceiocontrol, if a driver in the kernel state wants to perform similar operations with another driver, how can this problem be achieved? Next, we will provide a detailed description.
The main idea is to first get the handle of another driver, then construct an IRP,
can be used to initialize or reboot the system.
