When an interrupt is called from user mode, what CS does the processor use?
Interrupts in user mode

Re: Interrupts in user mode
I don't buy a claim to RTFM, then posting a vague question with no accurate answer possible and demonstrating absolutely no knowledge on what said reading actually taught you.
In other words: go do your homework, and read things properly and thoroughly for a change, because the complete answer is contained in one section of the manual:
Hint: INT n/INTO/INT 3—Call to Interrupt Procedure. INSTRUCTION SET REFERENCE, A-M Vol. 2A 3-401

Whatever the Gate descriptor tells it to. The descriptor contains a far pointer.
