[*] Check for low memory corruption [*] Set the default setting of memory_corruption_check [*] Reserve low 64K of RAM on AMI/Phoenix BIOSen [ ] Math emulation不选 数学协处理器仿真,486DX以上的cpu就不要选它了 [*] MTRR (Memory Type Range Register) support 内存类型区域寄存器。在 Intel P6...
As I mentioned in the previous section,lscpugathers the processor details from/proc/cpuinfofile. So, we can simply display the contents of this file usingcatcommand to check CPU details in Linux. $ cat /proc/cpuinfo Sample output: Check CPU information in Linux using cpuinfo file Unlike thels...

Command The command name of the task. 进程(或子进程)堆栈使用情况 -s Report stack utilization. The following values may be StkSize The amount of memory in kilobytes reserved for the task as stack, but not necessarily used. StkRef The amount of memory in kilobytes used as stack, referenced ...
Those were some of the commands to check CPU information on Linux based systems like Ubuntu, Fedora, Debian, CentOS etc. For some more command examples on checking cpu information check this post: How to Check Processor and CPU Details on Linux - Command Examples Most of the commands are com...
Linux kernel parameter command line设置 现在CPU2核以上比较普遍了,平时用linux上上网可能用不着双核甚至4核,大部分发行版内核都启用了CPU_HOTPLUG,到/sys/devices/system/cpu下可以看到文件夹cpu0、cpu1,除cpu0(这个不能关)每个文件夹下都有一个online文件,往里面写0就可以关闭核心,比如我的T7300,echo '0' >...
