The kernel is a very small part of the entire operating system. According to Google's R D strength, it is not that difficult to develop a kernel? Is it really difficult to develop the kernel, or is Google making Android use the Linux kernel based on some considerations? The kernel

TodaySo many servers and workstations around us run linux, so many friends want to understand the core mechanism of linux. However, as the kernel is too large, some friends are discouraged. (I also had this experience when I was in my sophomore year. When I saw some people watching

Programs running in the Linux kernel should always prevent competing states caused by concurrency. This will cause the data structure to be broken down and cause the kernel to crash in severe cases. Therefore, the kernel synchronization technology is very important to the driver developed by the kernel. People who do n

Question: How are you sure the machine will run a 64-bit kernel?
Answer: Running the 64-bit kernel requires 64-bit hardware. For AIX 5.2, all IBM eserver pseries 64-bit hardware can run 64-bit or 32-bit cores. The order is as follows:
#/usr/sbin/bootinfo-p
When running on a machine that can only run a 32-bit kernel, the string "32" is returned. If the machine
