Basic conceptsBlock Devices (Blockdevice)---is a random access device with a certain structure, the reading and writing of this device is block -based, he uses buffer zone to hold temporary data, waiting for the condition to mature, from the cache once written to the device or from the device to read the buffer at once area.Character devices (Character device)---is a sequential data flow device in which read and write is performed by character , and these characters are continuously formed into

locks and semaphores take the form of "get lock-access critical section-release lock".*************************************************************************************************************** **********5. MutexThe mutex and the semaphore are basically the same. Not introduced.Summary: Concurrency and race are widespread, these mechanisms are a good way to solve the problem, interrupt masking is rarely used alone, atomic operations can only be done for integers, so the spin lock and signal

Linux Network DriverI would like to use this article to commemorate the past yearsI. PrefaceIn Linux, the network driver is also a big head, how to understand the network drive is as a Linux driver engineers must have the skills. But the same equipment, in different people's hands will have different effects, the reason is that the driver is good or not.Two. Devi
