+qemu-system-ppc: extra IPI interrupt on core0
+Description of problem:
+When I try to emit an IPI interrupt from core0 to another core via the MPIC controller(IPIDR1—Interprocessor interrupt dispatch register 1), core0 itself generates an unwanted IPI interrupt.
+Steps to reproduce:
+1. Prepare ISR routine, something like:
+
+ void ipi_handler (void)
+ {
+ int core_id = CORE_ID_GET();
+ myprintf("\n IPI interrupt triggered on core:%d\n",core_id);
+ }
+2. Create a task and bind it to core0. This task is mainly to write the MPIC controller to emit IPI interrupts to other cores.
+ MPIC_REG_WRITE(MPIC_BASE + IPIDR1, **0xe**);
+
+3. run the test task
+Additional information:
+/* Below test was tested on Qemu6.1 */
+
+IPI interrupts are emitted by core:0
+
+**IPI interrupt triggered on core:0** /* it's a bug, it should not trigger on core 0. */
+
+IPI interrupt triggered on core:1
+
+IPI interrupt triggered on core:2
+
+IPI interrupt triggered on core:3
+
+
+This bug only occurs when "emitting an IPIDR1 interrupt from **core0**".
