I m studying x86 and Real Time Systems, and I have a question, that is:
Which steps x86 follows to handle any interrupt ?
When an interrupt occurs, the CPU does the following:
The ISR should do the following:
Start here with the Interrupt Descriptor Table. Basically, when an interrupt occurs, flow control jumps to this table and then on to whatever is in this table. Also, I believe all registers are pushed as soon as the interrupt occurs, but I m not 100% certain of this as it s been a long, long time since I ve dealt with this.
A teammate made the following claim: "Thread.interrupt() is inherently broken, and should (almost) never be used". I am trying to understand why this is the case. Is it a known best practice ...
it seems that as soon as data is ready for the host (such as when I use WriteFile to send a command to the HID in which I tell the HID to give back some data such as the port value) and the in packet ...
I just finished up my Microprocessors class in college just a few weeks ago, there we programmed in assembly only. We learned a fair amount (IMHO) about interrupts. Here is my question: I am ...
In my code, I use QueueUserAPC to interrupt the main thread from his current work in order to invoke some callback first before going back to his previous work. std::string buffer; std::tr1::...
I m reading a book on Windows Internals and there s something I don t understand: "The kernel handles software interrupts either as part of hardware interrupt handling or synchronously when a thread ...
I d like to kill threads that are stuck in deadlock state. First, we can detect thread ids in deadlock state using the findDeadlockedThreads() method of the ThreadMXBean class in java.lang.management. ...
It s been a while since I did any ASM, and decided to once again try and write a small bootloader, testing with qemu. My issue is with interupt 13, for some reason the carry flag is being set, so the ...
I would like to know if it is possible to automatically invoke a Java method when a hardware interrupt is raised.
