Sample code block is like this: intr_register_int(1, 3, INTR_OFF, intr_debug_handler_out, "#DB Debug Exception"); asm volatile( "pushfl \n\t" "orl $0x100, (%%esp) \n\t" "popfl \n\t" "nop \n\t" "nop \n\t" "outb %b0, %w1 \n\t" "nop \n\t" <------- Not getting Debug Trap before executing this "nop \n\t" "pushfl \n\t" "xorl $0x100, (%%esp) \n\t" "popfl \n\t" :: "a"(2), "Nd" (80) ); Debug handler simply prints the EIP from interrupt frame and I don't see the EIP of marked instruction. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
