Re: How does qemu detect the completion of interrupt execution？

[Duo jia]

I do some support on STM8 arch, the reference manual link is:

https://www.st.com/resource/en/reference_manual/cd00218714-stm8l050j3-stm8l051f3-stm8l052c6-stm8l052r8-mcus-and-stm8l151l152-stm8l162-stm8al31-stm8al3l-lines-stmicroelectronics.pdf

Chapter 12 describes interrupts as blow：

I don't kown when to check the "PENDING" because I can't get the when interrrupt exec over.

Is there a similar implementation in qemu？

That depends on the hardware. I can't answer unless you tell
me what the hardware is and give me a URL for its specification
or reference manual...
