* Use the APIC to determine the hardware processor id - i386Fernando Luis Vazquez Cao2007-05-091-2/+0
| | | | | | | | | | | | | | | | | | | | | | | hard_smp_processor_id used to be just a macro that hard-coded hard_smp_processor_id to 0 in the non SMP case. When booting non SMP kernels on hardware where the boot ioapic id is not 0 this turns out to be a problem. This is happens frequently in the case of kdump and once in a great while in the case of real hardware. Use the APIC to determine the hardware processor id in both UP and SMP kernels to fix this issue. Notice that hard_smp_processor_id is only used by SMP code or by code that works with apics so we do not need to handle the case when apics are not present and hard_smp_processor_id should never be called there.

* [PATCH] i386: Add __init to probe_bigsmpPrarit Bhargava2007-05-021-1/+1
| | | | | | | | | | | | Add __init to probe_bigsmp. All callers are __init and data being examined is __initdata. Resolves MODPOST warning similar to: WARNING: vmlinux - Section mismatch: reference to .init.data: from .text between 'probe_bigsmp' (at offset 0xc0401e56) and 'init_apic_ldr' Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>
* [PATCH] i386: make apic probe function non-initVivek Goyal2007-01-114-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | o struct genapic contains pointer to probe() function which is of type __init. Hence MODPOST generates warning if kernel is compiled with CONFIG_RELOCATABLE=y for i386. WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_summit' (at offset 0xc058b504) and 'apic_bigsmp' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_bigsmp' (at offset 0xc058b5a4) and 'cpu.4471' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_es7000' (at offset 0xc058b644) and 'apic_default' WARNING: vmlinux - Section mismatch: reference to .init.text: from .data between 'apic_default' (at offset 0xc058b6e4) and 'interrupt' o One of the possible options is to put special case check in MODPOST to not emit warnings for this case but I think it is not a very good option in terms of maintenance. o Another option is to make probe() function non __init. Anyway this function is really small so not freeing this memory after init is not a big deal. Secondly, from a programming perspective, probably genapic should not provide pointers to functions which have been freed as genapic is non __init and is used even after initialization is complete.

* [PATCH] i386: Avoid boot warning with apic=debugAndi Kleen2006-12-071-1/+3
| | | | | | | | There are two consumers of apic=: the apic debug level and the low level generic architecture code. early_param would warn when the low level code rejected "debug". Avoid this. Signed-off-by: Andi Kleen <ak@suse.de>
* [PATCH] i386: Replace i386 open-coded cmdline parsing withRusty Russell2006-09-261-30/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the open-coded early commandline parsing throughout the i386 boot code with the generic mechanism (already used by ppc, powerpc, ia64 and s390). The code was inconsistent with whether it deletes the option from the cmdline or not, meaning some of these will get passed through the environment into init. This transformation is mainly mechanical, but there are some notable parts: 1) Grammar: s/linux never set's it up/linux never sets it up/ 2) Remove hacked-in earlyprintk= option scanning. When someone actually implements CONFIG_EARLY_PRINTK, then they can use early_param(). [AK: actually it is implemented, but I'm adding the early_param it in the next x86-64 patch] 3) Move declaration of generic_apic_probe() from setup.c into asm/apic.h 4) Various parameters now moved into their appropriate files (thanks Andi). 5) All parse functions which examine arg need to check for NULL, except one where it has subtle humor value. AK: readded acpi_sci handling which was completely dropped AK: moved some more variables into acpi/boot.c Cc: len.brown@intel.com Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Signed-off-by: Andi Kleen <ak@suse.de>
* [PATCH] i386: Allow to use GENERICARCH for UP kernelsAndi Kleen2006-09-264-0/+5
| | | | | | | | | | | | There are some machines around (large xSeries or Unisys ES7000) that need physical IO-APIC destination mode to access all of their IO devices. This currently doesn't work in UP kernels as used in distribution installers. This patch allows to compile even UP kernels as GENERICARCH which allows to use physical or clustered APIC mode.

| | | | | | | | | | | | From: "Jan Beulich" <jbeulich@novell.com> When using apic= on the kernel command line, this had no effect for machines matched by either the ACPI MADT or the MPS OEM table scan.

* [PATCH] x86: sutomatically enable bigsmp when we have more than 8 CPUsVenkatesh Pallipadi2005-09-052-1/+24
| | | | | | | | | | | i386 generic subarchitecture requires explicit dmi strings or command line to enable bigsmp mode. The patch below removes that restriction, and uses bigsmp as soon as it finds more than 8 logical CPUs, Intel processors and xAPIC support.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-166-0/+245
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
