kernel thread vs user thread The most important difference is they use different memory, the kernel mode thread can access any kernel memory, while the user mode can only access the user memory. 相信世界是平的 谨记四个字“修身养性” 大江东去浪淘尽英雄,再牛B的人物最后也是一掊土 向善不是目的...
在Redhat的系统中,还有个经常看到的kernel启动参数——rhgb,rhgb表示redhat graphics boot,就是会看到图片来代替启动过程中显示的文本信息,这些信息在启动后用dmesg也可以看到 rhgb = redhat graphical boot – This is a GUI mode booting screen with most of the information hidden while the user sees a rotatin...
The KERNEL_THREAD_PRIORITY_FLOOR_VIOLATION bug check has a value of 0x00000157. This indicates that an illegal operation was attempted on the priority floor of a particular thread.
而另一个per-cpu变量kernel_stack,其定义如下: // file: arch/x86/kernel/cpu/common.cDEFINE_PER_CPU(unsignedlong,kernel_stack)=(unsignedlong)&init_thread_union-KERNEL_STACK_OFFSET+THREAD_SIZE; 宏DEFINE_PER_CPU内部将入参直接透传给了DEFINE_PER_CPU_SECTION宏,其定义如下: // file: include/linux/...
Kernel-level thread. A kernel-level thread employs a strict 1:1 model whereby each user thread maps directly to a kernel thread. The issue here is the potential overhead of the kernel creating and maintaining new threads, especially for applications that may use a lot of threads. However, ...
