Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: remove smpboot_32.c and smpboot_64.cGlauber de Oliveira Costa
Remove the last leftovers from the files. Move the ones that are still used to the files they belong, the others that grep can't reach, simply throw away. Merge comments ontop of file and that's it: smpboot integrated Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: move apicid mappings to smpboot.cGlauber de Oliveira Costa
They are i386 specific (the x86_64 definitions live elsewhere, and should remain there), so are enclosed around an ifdef Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: merge cpu_exit_clearGlauber de Oliveira Costa
this is the last remaining function in smpboot_32.c Since it is i386 specific, move it around an ifdef to smpboot.c Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: merge native_smp_prepare_cpusGlauber de Oliveira Costa
With the previous changes, code for native_smp_prepare_cpus() in i386 and x86_64 now look very similar. merge them into smpboot.c. Minor differences are inside ifdef Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: introduce smpboot_clear_io_apicGlauber de Oliveira Costa
x86_64 has two nr_ioapics = 0 statements. In 32-bit, it can be done too. We do it through the smpboot_clear_io_apic() inline function, to cope with subarchitectures (visws) that does not compile mpparse in Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change x86_64 sanity checks to match i386.Glauber de Oliveira Costa
They are mostly inocuous. APIC_INTEGRATED will expand to 1, check_phys_apicid_present is checking for the same thing it was before, etc. But the code is identical to i386 now, and will allow us to integrate it. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: add extra sanity checkGlauber de Oliveira Costa
This test exists in x86_64 and also applies to i386. So we add it Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change x86_64 native_smp_prepare_cpus to match i386Glauber de Oliveira Costa
An APIC test is moved, and code is replaced by the mach-default already defined function (smpboot_setup_io_apic). setup_portio_remap() is added, but it is a nop in mach-default. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: assign nr_ioapics = 0 in smpboot_hooks.hGlauber de Oliveira Costa
change smpboot_setup_io_apic() by to match x86_64 behaviour Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: additions to i386 native_smp_prepare_cpus.Glauber de Oliveira Costa
Add function calls to native_smp_prepare_cpus in i386 to match x86_64 Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: get rid of smp_boot_cpusGlauber de Oliveira Costa
This patch get rid of smp_boot_cpus(), since it does not boot any cpu anymore. Its code is split in a way to make it closer to x86_64 Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: use physical id when disabling smpGlauber de Oliveira Costa
if smp configuration is not found at all, hook into 0. This is done to match x86_64 Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: merge native_smp_cpus_doneGlauber de Oliveira Costa
They look similar enough, and are merged. Only difference (zap_low_mapping for i386) is inside ifdef Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: merge smp_prepare_boot_cpuGlauber de Oliveira Costa
it is practically the same between arches now, so it is moved to smpboot.c. Minor differences (gdt initialization) live inside an ifdef Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: integrate start_secondaryGlauber de Oliveira Costa
It now looks the same between architectures, so we merge it in smpboot.c. Minor differences goes inside an ifdef Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: integrate do_boot_cpuGlauber de Oliveira Costa
This is a very large patch, because it depends on a lot of auxiliary static functions. But they all have been modified to the point that they're sufficiently close now. So they're just merged in smpboot.c Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change boot_cpu_id to boot_cpu_physical_apicidGlauber de Oliveira Costa
This is to match i386. The former name was cuter, but the current is more meaningful and more general, since cpu_id can be a logical id. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: move stack_start to smp.hGlauber de Oliveira Costa
voyager would conflict with it, but the types are ultimately compatible. So remove the extern definition from voyager_smp.c in favour of the common one Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: move {un}map_cpu_to_logical_apicid to smpboot.cGlauber de Oliveira Costa
Move map_cpu_to_logical_apicid() and unmap_cpu_to_logical_apicid() to smpboot.c. They take together all the bunch of static functions they rely upon Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: add callin tests to cpu_upGlauber de Oliveira Costa
Now that we boot cpus here, callin_map has this meaning (same as x86_64) Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: change wakeup_secondary nameGlauber de Oliveira Costa
wakeup_secondary_via_INIT => wakeup_secondary_cpu. This is to match i386, where init is not always used. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: include mach_apic.h in smpboot_64.c and smpboot.cGlauber de Oliveira Costa
After the inclusion, a lot of files needs fixing for conflicts, some of them in the headers themselves, to accomodate for both i386 and x86_64 versions. [ mingo@elte.hu: build fix ] Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: call do_boot_cpu directly from native_cpu_upGlauber de Oliveira Costa
We don't need __smp_prepare_cpu anymore. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: minor adjustments for do_boot_cpuGlauber de Oliveira Costa
This patch provides minor adjustments for do_boot_cpus in both architectures to allow for integration Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: calibrate delay with irqs enabledGlauber de Oliveira Costa
We do it to make it close to x86_64. The later needs it, otherwise the nmi watchdog can get into the scene and kill us with a hammer. Enabling irqs here used to trigger a bug in i386. This is because time irq handling relies upon structures that are only initialized after smp initcalls (More precisely, it will find per_cpu(hrtimer_bases, cpu)->cb_pending list not initialized and crash) Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: provide an end_local_APIC_setup functionGlauber de Oliveira Costa
It splits setup_local_APIC in two, providing a function corresponding to the ending part of it. As a side effect, smp_callin looks the same between i386 and x86_64. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: wrap esr setting up in i386 in lapic_setup_esrGlauber de Oliveira Costa
it is a little bit more complicated than x86_64 due to erratas and other stuff, but its existance will ease integration Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: modify smp_callin in x86_64 to look like i386Glauber de Oliveira Costa
We introduce empty macros just to make them look like the same Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: don't span a new worker in __smp_prepare_cpuGlauber de Oliveira Costa
We can do it now that do_boot_cpu has its own worker. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: use create_idle struct in do_boot_cpuGlauber de Oliveira Costa
Use a new worker, with help of the create_idle struct to fork the idle thread. We now have two workers, the first of them triggered by __smp_prepare_cpu. But the later is going away soon. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: get rid of commenced mask.Glauber de Oliveira Costa
As we now boot cpus from cpu_up, we don't need it. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: boot cpus from cpu_up, instead of prepare_cpusGlauber de Oliveira Costa
After all the infrastructure work, we're now prepared to boot the cpus from cpu_up, and not from prepare_cpus. So the difference between cold boot and hotplug is effectively over, and the functions are used to the purposes they're meant to. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: do not zap_low_mappings in __smp_prepare_cpusGlauber de Oliveira Costa
It was okay when cpus were cold booted before this point. But with the new state machine, they will not have arrived to the trampoline yet. zapping low mappings will have the bad effect of breaking it completely after paging enablement Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: schedule work only if keventd is already runningGlauber de Oliveira Costa
Only call schedule_work if keventd is already running. This is already the way x86_64 does Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: don't initialize sibling and core maps during preparationGlauber de Oliveira Costa
it is redundant, since it is already done by set_cpu_sibling_map() Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: call nmi_watchdog_default in i386Glauber de Oliveira Costa
this does not exist, so it will be an empty macro Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: call check_nmi_watchdog explicitly in native_smp_cpus_doneGlauber de Oliveira Costa
With this, remove its late_initcall marker from nmi_32.c Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: unify nmi_32.h and nmi_64.hGlauber de Oliveira Costa
Two more files goes away. nmi_64.h and nmi_32.h gives birth to nmi.h Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: wipe get_nmi_reason out of nmi_64.hGlauber de Oliveira Costa
use mach_traps when it is supposed to be used. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: don't set maps in native_smp_prepare_boot_cpu()Glauber de Oliveira Costa
By this time, they are already set in init routines Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: move smp_intr_init away from smpboot_32.cGlauber de Oliveira Costa
We move it to apic_32.c, since it's irq related anyway, and only called from that file. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: include smpboot_hooks.h in smpboot_64.cGlauber de Oliveira Costa
We do it and also fix conflicts, which makes x86_64 automatically closer to i386 Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: include mach_wakecpu.h in smpboot_64Glauber de Oliveira Costa
Do it and also fix conflicts, which automatically makes x86_64 look closer to i386 Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-04-17x86: add subarch support (for headers) to x86_64Glauber de Oliveira Costa
this patch allows x86_64 to use subarch mach_ headers in practice, since x86_64 does not have any subarch, it will use mach_default. But it will allow for substantially less code duplication Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
