- Fix the the build breakage when PARAVIRT is defined but PCI is not This fixes problem reported at: http://marc.info/?l=linux-kernel&m=120525966600698&w=2 - Make is_vsmp_box() available even when PARAVIRT is not defined. This is needed to determine if tsc's are reliable as a time source even when PARAVIRT is not defined. - split vsmp_init to use is_vsmp_box() and set_vsmp_pv_ops() set_vsmp_pv_ops will do nothing if PCI is not enabled in the config.

is_vsmp_box() currently does not work on vSMPowered systems, as pci cfg space is not read correctly -- This patch fixes it. Signed-off-by:

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:

They are i386 specific (the x86_64 definitions live elsewhere, and should remain there), so are enclosed around an ifdef Signed-off-by:
-
Glauber de Oliveira Costa authored
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 de Oliveira Costa authored
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:
-

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:

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 de Oliveira Costa authored
This test exists in x86_64 and also applies to i386. So we add it Signed-off-by:
-
Glauber de Oliveira Costa authored
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:

change smpboot_setup_io_apic() by to match x86_64 behaviour Signed-off-by:

Add function calls to native_smp_prepare_cpus in i386 to match x86_64 Signed-off-by:
-
Glauber de Oliveira Costa authored
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 de Oliveira Costa authored
if smp configuration is not found at all, hook into 0. This is done to match x86_64 Signed-off-by:
-
Glauber de Oliveira Costa authored
They look similar enough, and are merged. Only difference (zap_low_mapping for i386) is inside ifdef Signed-off-by:
-
Glauber de Oliveira Costa authored
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 de Oliveira Costa authored
It now looks the same between architectures, so we merge it in smpboot.c. Minor differences goes inside an ifdef Signed-off-by:

Glauber de Oliveira Costa authored
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 de Oliveira Costa authored
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:

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 de Oliveira Costa authored
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:

Now that we boot cpus here, callin_map has this meaning (same as x86_64) Signed-off-by:
-

wakeup_secondary_via_INIT => wakeup_secondary_cpu. This is to match i386, where init is not always used. Signed-off-by:

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:

We don't need __smp_prepare_cpu anymore. Signed-off-by:

This patch provides minor adjustments for do_boot_cpus in both architectures to allow for integration Signed-off-by:

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:

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 de Oliveira Costa authored
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:
