Here, I will summarize my development experience and be familiar with kernel device nodes, which is helpful for Kernel-related driver learning and development.
1. View CPU Information
On the android application settings page, you can view information about the mobile phone or tablet Android devices in the menu. This information is an interface reserved by the kernel.
As a kernel developer, you can view this information directly in serial port debuggi
than FSB.
The speed of FSB is usually closely associated with the speed of the front-end bus and memory. So when you raise the CPU FSB, the performance of the CPU, system, and memory also increases.
There are two main ways of CPU overclocking:
One is hardware settings and the other is software settings. Hardware settings are more commonly used, it is divided
[1] Physical CPU: The number of CPUs on the slot in the actual server.
Number of physical CPUs: There are several physical IDs that can be counted without duplicates.
[2] Logical CPU
Linux users are certainly not unfamiliar with the/proc/cpuinfo file. It is used to store CPU hardware information.The information content lists the specifications of the processor
Q: Can the CPU fan be universal, if not general how to choose the CPU fan? (I use the Sai Yang 2.4G)
For:
The CPU fan is generic and is not generic. Common in the market is not universal fan, cheaper, universal fan belongs to high-end products, is recommended by DIY enthusiasts, the price is more expensive.1, if you just want to install a fan 2.4G, then go to t

The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests.
Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different).
The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.
Of the CPUs currently produced by Intel, Pentium 4 and Celeron are PC-oriented, Xeon, XEONMP, and Itanium are for workstations and servers. Where Itanium is a completely different 64-bit CPU from other CPUs, the design is not considered for existing Windows applications. While other processors vary in their maximum operating frequency, FSB (front bus frequency), and cache size, the internal design is essent

See there are two waiters, two queues, think there are two chefs, so the guests A and B sent to 1 A and 1 B to queue, completely do not know the actual situation of the kitchen-there are several chefs.Back to reality, what kind of CPU do I need?Here, I discuss the situation.1) Internet, chat QQ, simple office use (such as Office document processing), the elderly machineCeleron in
End of 2015:Intel Braswell is a family of ultra-low power mobile and desktop platforms, the existing Celeron n3000/n3050/n3150, Pentium N3700 four models, wherein the N300 thermal design power consumption is only a small 4W, the other three are 6w,n3150 is a mini-machine, Thin client and other devices like the favorite, already have a large number of products.Intel today announced that it will upgrade the Braswell, with core stepping from C to D, and
1.CPU frequency higher performance? not necessarily. This is in many novice among the misunderstanding. CPU performance depends on a number of comprehensive parameters, not necessarily the root frequency proportional. Of course, in the same series of CPUs, such as Celeron 4, the higher the frequency of high performance. 2. Why
