dispatch point will appear, If a process process2 with a higher priority than the currently interrupted process Process1 in the CPU1 's running queue, the interrupted process Process1 will be swapped out of the processor, even if it is running in the kernel state at this time.If the PROCESS3 on the CPU2 also enters the kernel state through the system call and accesses the same critical section, the deadloc

stability tree after tests in the Development tree. Once the development tree has been sufficiently developed, the development tree will become a new stable tree. The development number is reflected in the source program version number. The source program version number is in the form of X. y. z: for a stable tree, Y is an even number. For a development tree, Y is bigger than the corresponding stable tree (therefore, it is an odd number ). So far, the maximum version of the stability tree is 2.

The Linux kernel module provides a simple introduction to the overall architecture of the Linux kernel, which is already large and includes components or many more. How do we include the required parts in the kernel?One way is to compile all the required functions into the

One page The kernel uses the physical page as the basic unit of memory management; the memory management unit (MMU) converts the virtual address to the physical Address, usually in the unit of page processing. MMU manages the tables in the system in the unit of page size. 32-bit system: page size 4 kb 64-bit system: 8 KB page size The kernel uses the corresponding data structure to represent each
