C # inline-asm/Embedded x86 assembly, C # Can it be embedded in assembly? In my eyes, C # is impossible as a middle-and upper-layer Language. Why do I think the middle-and upper-layer languages place assembly code? I can see from C # retaining pointers. Many people will not believe that C # can use assembly code, but C # will be more troublesome. C # cannot be used directly. Inline-asm (inline-asm): C # Only auto-asm dynamic assembly is supported.

How is the grub parameter of android-86 modified?In fact, there is a need to mount the partition first, which is different from the Linux operating system.General Linux systems, such as the Ubuntu,grub configuration, are stored in the/boot/grub/grub.cfgHowever, the Android configuration is not mounted, but also can not be searched, the following steps need to be taken:(1) Su enters root permission(2) mkdir/data/fs (data directory is the original)(3) Mount-t ext2/dev/block/sda1/data/fs(4) Cd/data

register the information of these stacks for temporary preservation in the TCB (e.g.).The steps for creating a stack of the X (x=0,1,2) privilege level are as follows:1. Apply for memory, allocate space for stack;2. Create a stack segment descriptor (DPL=X) in the LDT;3. Register the Stack's information in the TCB, including the stack size, base address, selector (rpl=x), and initial value of espx (=0);I think the size of the stack and the registration of the base site is not necessary, because

Linux x86 Assembler Programming-general Linux technology-Linux programming and kernel information. The following is a detailed description. Essentially, this article combines two programming things that interest me most: the Linux operating system and assembly language programming. neither of these two needs to be introduced (or should not); like Win32 assembly, Linx Assembly runs in 32-bit protection mode... however, it has another distinct advantage

information.A flat mode is used, which results in the use of DS to read CS data, or you can execute code other than CS such as: DS or SS. At this stage of segmentation, processor cannot prevent the code in the stack from being able to perform this situation. Until the paging protection measures are resolved.Since the flat mode is used, the logical address is consistent with the linear address. Cause the modern operating system has weakened the concept of logical address, virtual address is gene
