Introduction of GlogGlog is a lightweight C + + log library developed by Google that is simple to use and lightweight in the program.The following features are primarily supported:1 parameter setting to control logging behavior by setting flag parameters;2 severity rating, logging based on log severity rating;3 log information can be recorded conditionally;4 Conditional Abort program, rich conditions to determine the macro, can be preset program termination conditions;5 abnormal signal proces
Azure currently has two modes of operation: ASM and ARM.In the domestic azure, we are all using ASM mode. However, this model has many limitations, such as that each VM must have a public address, deployment cannot be deployed in bulk, and so on. ARM has made great changes to the overall architecture of Azure. Many of the limitations in ASM have been removed. Is the main difference between the two modes:This year, Azure will fully support the
First, thumb instructions and arm instructions
The thumb instruction is 16 bits, so the storage code is highly dense and saves storage space. But the function is not complete, it is only the arm instruction (32 bit) set supplement, is a subset under the arm instruction set. In the early stages we don't need to know this knowledge, as long as there is a concept t

Porting process:
Before porting the HOSTAPD, you need to migrate OpenSSL and LIBNL two libraries, and after trying to find openssl-0.9.8g and libnl-1.1 Two versions are better compiled, then choose these two versions. Their porting is not covered in this article because there are articles dedicated to their porting process.
Download and extract the Hostapd-0.8-snapshot source code and

Abstract
ARM servers are becoming increasingly common, making server technologies such as virtualization for arm of growing Importa nCE. We present the study (1) of ARM virtualization performance on server hardware, including multi-core measurements of Two popular ARM and x86 hypervisors, KVM and Xen. We show how

The functions of the arm-Linux tool are as follows:
Arm-linux-addr2line handleProgramThe address is converted to the file name and row number. In the command line, give it an address and an executable file name, and it will use the debugging information of this executable file to indicate which file is on the given address and
support for the crossover environment, providing additional functionality to facilitate the development of embedded applications.
Click Next to the "Select Configurations" page, and we take the default, direct next step, to the "Cross GCC Command" setting. Here we can fill in the Cross compilation tool chain of the prefix and path, such as:
Cross compiler prefix:arm-arago-linux-gnueabi-
Cross compiler path:/data/linux/ti-sdk5/linux-devkit/bin
The example above is the cross compilation package

When I wrote "getting started with the neon iPhone", I thought that the reader had a better understanding of the processor knowledge of iOS devices. However, after reading some discussions on the internet, I found that the original knowledge is not popular, and it is my fault. In addition, I think understanding these things is helpful for iPhone programming (not just for those who like neon). Even if you are using objective-C, even if you are not familiar with it, it will not affect your work, b

Of course, as a mobile device for Android phones, the iphone is also used with the arm architecture of the processor. If yo
