WebJan 13, 2012 · The entire base would be function call is predictive and interrupt is non predictive. Interrupt occurs from HW or SW. The HW interrupts are non predictive with two kinds as maskable and non-maskable. SW interrupts are predictive and generally used for OS System calls. where as Function calls are predictive from the program execution point. WebJan 4, 2024 · Dear JackCrens, I suppose you are saying function call and interrupt "shares" the same stack. Please kindly confirm my understanding is correct: 1. main program runs. Stack is empty. 2. A function is called. A stack frame is thus created, and some data (function parameters, local variables, etc) are pushed on stack. 3.

WebMay 12, 2024 · To access interrupt routing info the OS calls ACPI function "_PRT". This checks the PICM variable and returns routing for the APIC mode case. In the case when we boot with the option noapic: OS finds ACPI tables; ОS executes ACPI function "_PIC", passing it the argument stating that the boot should happen in PIC mode. WebAnd the implementation of an interrupt function looks like this: void CInterruptVectorTable::IsrNMI(void) { pThis->virtualVectorTable.IsrNMI(); } So that will call a static method of another class (which can be private), which then can contain another static this-pointer to gain access to member-variables of that object (only one). mini cooper of universal city
