: #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

how to eliminate problems caused by non-alignment access// You can also see that the command difference between non-alignment access and alignment access causes efficiency problems.} Sizeof determines the struct size Typedef struct{Int;Char B;} A_T;Typedef struct{Int;Char B;Char C;} B _t;Typedef struct{Char;Int B;Char C;} C_t;Void main (){Char * A = 0;Cout Cout Cout Cout Cout }Why is that? 2. Syntax:Sizeof has three syntax forms:1) sizeof (object); // sizeof (object );2) sizeof (type_name); //

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. 1. development platform. here we need to know whether it is PPC or smartphon. in fact, this

cleared, so the irq_pending flag cannot be cleared here, so the action is still null, in this way, the handle_irq_event function cannot be executed again. 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

Connection Manager on the PDA by checking the Registry. In PPC 2003, the Registry path is: [HKEY_LOCAL_MACHINE \ comm \ connmgr], as shown in: The destinations field corresponds to all our available network connections. This is the same effect as the connmgrenumdestinations () method. In the default Internet settings, we will see the guid of cmnet, as follows: Here there is a destid item, which corresponds to our long-lost guid E) connm

The entire structure is very clear and can help you understand the working principles of search engines, search engine marketers (SEO PPC) have basic knowledge.

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);

measures here, of course, you can pack it into a package and directly throw it, but this is stupid, like a snail carryingThe heavy shell is moving, and the user can wait for so long. There are many smart practices, depending on your actual needs, such as compression, batch processing, and so on.In fact, the entire development of the server, every detail determines the success or failure of your server. After developing a Linux server project, I personally decided that an important factor that m

network with other methods: PPC/TPC Model These two models share the same idea, that is, to let every incoming connection do things on its own, so don't bother me any more. Only PPC opens a process for it, while TPC opens a thread. But don't bother me. There is a price. It requires time and space. When there are too many connections, so many processes/threads will switch, and this overhead will come up; t

the vsid, R4 stores the virtual address, R5 stores the Linux page table entry, and R6 stores the Linux PTE before _ page_hashpte, r7 saves the offset to the address (0 when MMU is enabled and-kernelbase: 0xc0000000 when off ). Let's take a look at several hash_page_patches, which involve two functions in hash_low_32.s. create_hpte is relatively simple. The function is to create hpte. In the assembly code, it is to fill R5, as shown below: _ Global (create_hpte)/* converts Linux-style PTE (R5) t

Because the code at the tests layer references the code at the area library layer, the code at the area library layer references the code at the uial layer. Therefore, we first use vs2005 to open the project under the javasactionlayer. The extract actionlayer of calview has two versions for PPC and smartphone respectively.
