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

What is Scrapy?A: Scrapy is an open-source web crawler framework written using the Python language (based on the Twistec framework), with a clear structure, a low degree of coupling between modules, and a strong expansion capability to meet a variety of needs. (we introduced the use of requests, beautifulsoup, selenium and so on is equivalen

context (various universal registers), use STP to save the hardware site. Here x29 is the FP (frame pointer), X9 saves the stack POINTER,LR is the returned PC value. The Save action for the Pre task CPU context is completed at the a code.(5) is similar to step (3) Except for the next task. This time x8 points to the CPU context of the next task.(6) and step (4) is similar, the difference is that the operation here is to restore the next task CPU context. Execution to code B, all registers have

Linux driver framework. I. Linux Device Drivers and external interfaces can be divided into three parts:: 1. interfaces between the driver and the operating system kernel. This is done through the file_operations (include/Linux/fs. h) data structure. 2. Drivers and system-guided interfaces. This part uses the driver to

Access to the index.html file via a browser, as shown in result 3-3, as in the third step, the policy in SELinux granted the appropriate Read permission through the Allow command, so the access was successful.For the above procedures used in the command, such as Echo, Sesearch, Chcon, etc., see the Man manual, here no longer repeat; for SELinux polic

The secondary device number assigned by USB core when the USB driver bundled to the interface uses the USB main device number. Valid only after successful invocation of the Usb_register_dev. Except that it can be described with struct usb_host_config, I don't know much about configuration until now. The entire USB device can be described with struct usb_device, but basically it will only be used to initialize the interface of the function, and the actual use should be the custom structure we me
