I am trying to run DPDK application on x86_64 Machine, On this process trying to do core isolation and assign one application to isolated Core. While doing Core Isolation, achieved "Interrupt count increment stop on isolated core" in all interrupts except CAL (Function Call Interru...
GCC支持很多种调用规范,常用的有cdecl、fastcall、thiscall、stdcall、interrupt。C语言的默认规范是cdecl,这也是内核代码所用的规范,当然内核中的中断和系统调用ABI另有定义。 GCC的x86平台cdecl规范详 cdecl属于Caller clean-up类规范。在调用子程序(callee)时,x87浮点寄存器ST0-ST7必须是空的,在退出子程序时,ST1-S...
In the /proc/interrupts file, there is one entry called the Function call interrupts. Can anyone please explain to me how this interrupt is generated or what it does? Thanks! $ cat /proc/interrupts CPU0 CPU1 0: 7555 0 IO-APIC-edge timer 1: 2 0 IO-APIC-edge i8042 4: 2 0 IO-AP...

中断服务函数不是在代码里面直接调用的，是产生中断时系统自动调用的，不能直接调用ISR 把调用中断服务函数的地方给注释掉就行了 void fudu(void){f=kbscan();//into();...虽然INT0中断被打开，但是你的定时器启动了吗？
two paragraphs, most experienced developers will recommend that you never call an interrupt from a function. Interrupts are triggered by the hardware, possible approach is to have an interrupt set a global variable to some value than...
The IoAllocateIrp routine allocates an IRP, given the number of I/O stack locations for each driver layered under the caller, and, optionally, for the caller.
The KeReleaseInterruptSpinLock routine releases an interrupt spin lock acquired by KeAcquireInterruptSpinLock.

The IoAttachDeviceToDeviceStack routine attaches the caller's device object to the highest device object in the chain and returns a pointer to the previously highest device object.
