Hi all, I have been trying to simulate the occurrence of an interrupt during the execution of an application in TCG mode. Specifically the interrupt number is 239 (local apic timer interrupt).
Briefly, I am using the -loadvm command to load a previously saved state of QEMU. When I load the saved state, the execution of an application which was paused when I saved the state will now complete. At a certain point in its execution, I need to make TCG-QEMU execute an interrupt. I can understand that the function do_interrupt_all() is involved in handling interrupts in QEMU. But I am confused where in code will be a good place to call this code. I can see that QEMU calls cpu_handle_interrupt() at the end of translating and executing one block every time. So say I want to call do_interrupt_all() in the middle of translating a translation block, is this possible ? - Are there mechanisms available to achieve this ? Regards, Arnab
