Open-Source Linux Development for AMD Embedded Processors
找到了AMD公开的文档Open-Source Register Reference for AMD Family 17h Processors,CPU ID CPB Bit的确是CPUID_EDX 0x80000007 Bit9没错。这下我彻底傻眼了。 百般无奈,继续看起了内核的代码,突然注意到还有一处地方引用了X86_FEATURE_CPB,arch/x86/kernel/cpu/amd.c的 init_amd_zn 函数: static void init...
While micro-architecture specific optimizations are rather common place within the Linux x86_64 kernel for various Intel and AMD CPU families with various performance tricks, the ARM64 Linux kernel maintainers are against introducing new micro-architecture specific optimizations as it affects new ARM p...
Check for non-fatal errors on AMD Athlon/Duron / Intel Pentium 4 每5秒检测一次这些cpu的非致命错误并纠正它们,同时记入日志 check for P4 thermal throttling interrupt 当P4的cpu过热时显示一条警告消息 Enable VM86 support 虚拟X86支持,在DOSEMU下运行16-bit程序或XFree86通过BIOS初始化某些显卡的时候才需要...

[ ] Timer events oriented (TEO) governor (for tickless systems) > 不选。Timers subsystem -> Timer tick handling (Idle dynticks system (tickless idle)) 选项相关项,时间子系统选tickless就选上这一项。 [*] Cpuidle Driver for Intel Processors ...
[ ] Old AMD GART IOMMU support > 不选,AMD平台相关。 [ ] Enable Maximum number of SMP Processors and NUMA Nodes > 不选,开启内核支持最大SMP处理器和最大NUMA节点数量,主要用于调试目的。 (8) Maximum number of CPUs > CPUs numer获取: cat /proc/cpuinfo | awk '/cpu cores/ {a=a+$4;};EN...
But if we are in an NMI/MCE/DEBUG/whatever super-atomic entry context,which might have triggered right after a normal entry wrote CS to the stack but before we executed SWAPGS, then the only safe way to check for GS is the slower method: the RDMSR. ...
