-Subject: x86/apic: Fix restoring boot IRQ mode in reboot and kexec/kdump
-
-From: Baoquan He <bhe@redhat.com>
-
-commit 339b2ae0cd5d4a58f9efe06e4ee36adbeca59228 upstream.
-
-This is a regression fix.
-
-Before, to fix erratum AVR31, the following commit:
-
- 522e66464467 ("x86/apic: Disable I/O APIC before shutdown of the local APIC")
-
-... moved the lapic_shutdown() call to after disable_IO_APIC() in the reboot
-and kexec/kdump code paths.
-
-This introduced the following regression: disable_IO_APIC() not only clears
-the IO-APIC, but it also restores boot IRQ mode by setting the
-LAPIC/APIC/IMCR, calling lapic_shutdown() after disable_IO_APIC() will
-disable LAPIC and ruin the possible virtual wire mode setting which
-the code has been trying to do all along.
-
-The consequence is that a KVM guest kernel always prints the warning below
-during kexec/kdump as the kernel boots up:
-
- [ 0.001000] WARNING: CPU: 0 PID: 0 at arch/x86/kernel/apic/apic.c:1467 setup_local_APIC+0x228/0x330
- [ ........]
- [ 0.001000] Call Trace:
- [ 0.001000] apic_bsp_setup+0x56/0x74
- [ 0.001000] x86_late_time_init+0x11/0x16
- [ 0.001000] start_kernel+0x3c9/0x486
- [ 0.001000] secondary_startup_64+0xa5/0xb0
- [ ........]
- [ 0.001000] masked ExtINT on CPU#0
-
-To fix this, just call clear_IO_APIC() to stop the IO-APIC where
-disable_IO_APIC() was called, and call restore_boot_irq_mode() to
-restore boot IRQ mode before a reboot or a kexec/kdump jump.
