The latest LinuxKernel3.0 kernel test version rc5 has been released today. The official Ubuntu kernel website only has rc4 for the oneiric kernel. The method for directly downloading source code on the internet is too troublesome and causes the entire system to crash. Therefore, we recommend that you download the debian package kernel of LinuxKernel3.0rc4 on the ubuntu official website. The new Linux kernel supports Intel, Alpha, PPC

The recent decline of Ubuntu has become a hot topic for discussion by netizens. Based on DebianGNU/Linux, Ubuntu supports x86, amd64 (x64), and ppc architectures. It is an open-source GNU/Linux operating system created by a global professional development team (CanonicalLtd. Provides a support platform for desktop virtualization. Will the disappearance of Ubuntu be a disaster? Let's take a look at the opinions of netizens on Ubuntu: GaryNewell: after

1. What is Radio?Radio is a wireless communication module driver, ROM is a system program, radio responsible for network communications, ROM and radio can be separate brush, non-impact. If your phone has a communication problem after you refresh the ROM, you can refresh the radio to try it.2. What is RAM? The full name, random Access memory, is the mobile storage part of the PPC for storing and saving data. It can be read and written at any time, and
:
#ifdef CONFIG_PPCstatic boot_os_Fcn do_bootm_linux;#elseextern boot_os_Fcn do_bootm_linux;#endif
The precompiled macro here illustrates that the do_bootm_linux () function of the CPU that is not in the PPC architecture is not implemented in this file (extern ). It is conceivable that the implementation of this function should be related to the architecture. Specifically, the implementation of the ARM architecture is in the lib_arm/arml

symbolic link include/ASM to point to the file related to the target architecture. For example, if you compile code for PPC, include/ASM points to include/ASM-PPC. Kbuild also compiles include/Linux/Autoconf. h and include/Linux/config files. Then start recursion from the root directory.Each sub-MAKEFILE file is relatively simple and points out how to compile the target file, such as The makefile fragment
Generally, when formulating network protocols, the client often needs to generate or obtain unique and non-duplicate IDs, supplemented by platform and version information as part of the Protocol, backend servers can perform statistical processing based on the information. here we will make a summary of the methods for obtaining these commonly used information.

In this case, the handle_irq_event function is resumed. When handle_irq_event returns, check the irq_pending flag. If this flag exists, it indicates that handle_irq_event has been interrupted during execution and has not been processed. Therefore, the handle_irq_event function is executed cyclically again. Until the irq_pending flag does not

5. sizeof pointer variableIf you have learned the data structure, you should know that the pointer is a very important concept, which records the address of another object. Since the address is stored, it is equal to the width of the computer's internal address bus. Therefore, in a 32-bit computer, the return value of a p
the address is stored, it is equal to the width of the address bus in the computer. So in a 32-bit computerThe return value of a pointer variable must be 4 (note that the result is in bytes). It can be predicted that, in the next 6The sizeof result of the four-bit pointer variable is 8.Char * Pc = "ABC ";Int * PI;String * pS;Char ** PPC = PC;Void (* PF) (); // function pointerSizeof (PC); // The result is 4Sizeof (PI); // The result is 4Sizeof (PS);
