2009-01-29x86, smp: remove mach_ipi.hIngo Molnar
Move mach_ipi.h definitions into genapic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-07x86: smp.h move safe_smp_processor_id declartion to cpu.hJaswinder Singh Rajput
Impact: cleanup Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-31kdump: forcibly disable VMX and SVM on machine_crash_shutdown()Eduardo Habkost
We need to disable virtualization extensions on all CPUs before booting the kdump kernel, otherwise the kdump kernel booting will fail, and rebooting after the kdump kernel did its task may also fail. We do it using cpu_emergency_vmxoff() and cpu_emergency_svm_disable(), that should always work, because those functions check if the CPUs support SVM or VMX before doing their tasks.

2008-11-12x86: move nmi_shootdown_cpus() to reboot.cEduardo Habkost
Impact: make nmi_shootdown_cpus() available to the rest of the x86 platform Now nmi_shootdown_cpus() is ready to be used by non-kdump code also. Move it to reboot.c. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-12x86 kdump: make nmi_shootdown_cpus() non-staticEduardo Habkost
Impact: make API available to the rest of x86 platform code Add prototype to asm/reboot.h. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-12x86 kdump: make kdump_nmi_callback() a function ptr on crash_nmi_callback()Eduardo Habkost
Impact: extend nmi_shootdown_cpus() with a callback The reboot code will use a different function on crash_nmi_callback(). Adding a function pointer parameter to nmi_shootdown_cpus() for that. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-12x86 kdump: create kdump_nmi_shootdown_cpus()Eduardo Habkost
Impact: cleanup For the kdump-specific code that was living on nmi_shootdown_cpus(). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-12x86 kdump: move crashing_cpu assignment to nmi_shootdown_cpus()Eduardo Habkost
Impact: cleanup This variable will be moved to non-kdump-specific code. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-11-12x86 kdump: extract kdump-specific code from crash_nmi_callback()Eduardo Habkost
Impact: cleanup The NMI CPU-halting code will be used on non-kdump cases, also (e.g. emergency_reboot when virtualization is enabled). Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-27x86: allow machine_crash_shutdown to be replacedGlauber Costa
This patch a llows machine_crash_shutdown to be replaced, just like any of the other functions in machine_ops Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2008-04-17x86: move ipi definitions to mach_ipi.hGlauber Costa
take them out of the x86_64-only asm/mach_apic.h Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2007-12-03x86: disable hpet legacy replacement for kdumpOGAWA Hirofumi
we should also add hpet_disable() for kdump. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2007-10-24x86: fix CONFIG_KEXEC build breakageMike Galbraith
X86_32 build fix to commit 62a31a03b3d2a9d20e7a073e2cd9b27bfb7d6a3f Signed-off-by: Mike Galbraith <efault@gmx.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2007-10-23x86: unify crash_32/64.cHiroshi Shimamoto
Most of contents in crash are same. Signed-off-by: Hiroshi Shimamoto <h-shimamoto@ct.jp.nec.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
