gibbs a9c07a6f67 Add support for suspend/resume/migration operations when running as a ... Xen PVHVM guest. Submitted by: Roger Pau Monné Sponsored by: Citrix Systems R&D Reviewed by: gibbs Approved by: re (blanket Xen) MFC after: 2 weeks sys/amd64/amd64/mp_machdep.c: sys/i386/i386/mp_machdep.c: - Make sure that are no MMU related IPIs pending on migration. - Reset pending IPI_BITMAP on resume. - Init vcpu_info on resume. sys/amd64/include/intr_machdep.h: sys/i386/include/intr_machdep.h: sys/x86/acpica/acpi_wakeup.c: sys/x86/x86/intr_machdep.c: sys/x86/isa/atpic.c: sys/x86/x86/io_apic.c: sys/x86/x86/local_apic.c: - Add a "suspend_cancelled" parameter to pic_resume(). For the Xen PIC, restoration of interrupt services differs between the aborted suspend and normal resume cases, so we must provide this information. sys/dev/acpica/acpi_timer.c: sys/dev/xen/timer/timer.c: sys/timetc.h: - Don't swap out "suspend safe" timers across a suspend/resume cycle. This includes the Xen PV and ACPI timers. sys/dev/xen/control/control.c: - Perform proper suspend/resume process for PVHVM: - Suspend all APs before going into suspension, this allows us to reset the vcpu_info on resume for each AP. - Reset shared info page and callback on resume. sys/dev/xen/timer/timer.c: - Implement suspend/resume support for the PV timer. Since FreeBSD doesn't perform a per-cpu resume of the timer, we need to call smp_rendezvous in order to correctly resume the timer on each CPU. sys/dev/xen/xenpci/xenpci.c: - Don't reset the PCI interrupt on each suspend/resume. sys/kern/subr_smp.c: - When suspending a PVHVM domain make sure there are no MMU IPIs in-flight, or we will get a lockup on resume due to the fact that pending event channels are not carried over on migration. - Implement a generic version of restart_cpus that can be used by suspended and stopped cpus. sys/x86/xen/hvm.c: - Implement resume support for the hypercall page and shared info. - Clear vcpu_info so it can be reset by APs when resuming from suspension. sys/dev/xen/xenpci/xenpci.c: sys/x86/xen/hvm.c: sys/x86/xen/xen_intr.c: - Support UP kernel configurations. sys/x86/xen/xen_intr.c: - Properly rebind per-cpus VIRQs and IPIs on resume.		2013-09-20 05:06:03 +00:00
