This mapping already exists in x86_64, just provide it for i386 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
take them off smp_{32,64}.h and move to smp.h Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Done to match x86_64 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
We have already removed the only condition that could fail here. so just don't test for any return value Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Do tests before do_boot_cpu in native_cpu_up for i386. Tests are a little bit broader than originally, and are the same as x86_64. Test for smp_callin is not applicable right now and is deferred. Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Put it in a disable_smp() function, as x86_64 does Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Isolate all sanity checking in a smp_sanity_check() function as x86_64 does. Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
goal is to have i386 and x86_64 closer, so we add barriers to match Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
This patch does not change the behaviour of x86_64, since APIC_INTEGRATED is always defined as (1). But the code now matches exactly i386 version (well, this part of the code, at least) Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
it is always integrated, so define as 1. Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
it does not need to be inside lock. Do the way i386 does. Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
This is done so we call setup_secondary_clock() in the same place x86_64 does. A separate patch for this is appearantly not needed. But clock initialization is such a delicate thing, that it's safer to do this way Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
the call to idle is guaranteed to do it. Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
This matches x86_64 behaviour, which is a superior one IMHO Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
now that it is the same between arches, put it into smpboot.c Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Call it conditionally for secondary cpus. This behaviour matches i386 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Call this function instead of identify_cpu in bugs_64.c Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
provide two specialized identify_secondary_cpu() and identify_boot_cpu() routines for x86_64. Although not strictly needed, they are functionally correct, and will ease integration with i386 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
This will ease integration with i386 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
The split of smp_store_cpu_info in a quirks-only part will ease integration with x86_64 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
It is used to match i386. The definition for the non-paravirt case is moved to smp.h instead of smp_32.h Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
This patch replaces apic_read() for apic_read_around() and apic_write for apic_write_around() in smpboot_64.c We do it to have a common usage between x86_64 and i386. In the former, it will always simply expand to apic_write Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
Add loglevel facilities to printks in __inquire_remote_apic. the levels are the ones to match x86_64 ones. Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>
-
change some variables' types in __inquire_remote_apic to match x86_64 Signed-off-by: NGlauber Costa <gcosta@redhat.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

When acpi=off or there is no SRAT defined, apicid_to_node is got from K8 Northbridge PCI configuration space in k8_scan_nodes() in arch/x86_64/mm/k8toplogy.c. The problem is that it assumes bsp apic id is 0 at that point. For four socket system with Quad core cpus installed, all cpus apic id is offset by 4, and bsp apic id is 4. For eight socket system with dual core cpus installed, all cpus apic id is offset by 2, and bsp apic id is 2. We need get boot_cpu_id --- bsp apic id, before k8_scan_nodes by called. So create early_acpi_boot_init and early_get_smp_config for get boot_cpu_id. Signed-off-by: NYinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

<asm-x86/nops.h> describes certain multibyte instructions as "generic" nops when in fact they aren't nops at all in 64-bit mode (missing REX.W causing truncation of a register). Update the comment to state that K8 or P6 style nops should be used in 64-bit mode. This matches what the alternatives code does.
