2009-02-26x86: apic: simplify secondary CPU wakeup methodsIngo Molnar1-8/+1
Impact: cleanup - rename apic->wakeup_cpu to apic->wakeup_secondary_cpu, to make it apparent that this is an SMP-only method - handle NULL ->wakeup_secondary_cpus to mean the default INIT wakeup sequence - this allows simplification of the APIC driver templates.

2009-02-26x86: remove update_apic from x86_quirks, fixIngo Molnar1-0/+17
Impact: build fix wakeup_secondary_cpu_via_init(), the default platform method for booting a secondary CPU, is always used on UP due to probe_32.c, if CONFIG_X86_LOCAL_APIC is enabled but SMP is off. So provide a UP wrapper inline as well. Cc: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-26x86: don't compile vsmp_64 for 32bitYinghai Lu1-0/+7
Impact: cleanup that is only needed when CONFIG_X86_VSMP is defined with 64bit also remove dead code about PCI, because CONFIG_X86_VSMP depends on PCI Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-26x86: remove update_apic from x86_quirksYinghai Lu1-3/+4
Impact: cleanup x86_quirks->update_apic() calling looks crazy. so try to remove it: 1. every apic take wakeup_cpu member directly 2. separate es7000_apic to es7000_apic_cluster 3. use uv_wakeup_cpu directly Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-22x86: select x2apic ops in early apic probe only if x2apic mode is enabledSuresh Siddha1-1/+1
If BIOS hands over the control to OS in legacy xapic mode, select legacy xapic related ops in the early apic probe and shift to x2apic ops later in the boot sequence, only after enabling x2apic mode. If BIOS hands over the control in x2apic mode, select x2apic related ops in the early apic probe. This fixes the early boot panic, where we were selecting x2apic ops, while the cpu is still in legacy xapic mode.

2009-02-17x86, apic: rename 'genapic' to 'apic'Ingo Molnar1-9/+9
Impact: cleanup Now that all APIC code is consolidated there's nothing 'gen' about apics anymore - so rename 'struct genapic' to 'struct apic'. This shortens the code and is nicer to read as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: remove ->store_NMI_vector()Ingo Molnar1-1/+0
Impact: cleanup It's not used by anything anymore. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: clean up the cpu_2_logical_apiciddeclarationIngo Molnar1-0/+4
extern declarations were scattered in 4 files - consolidate them into apic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86, apic: merge genapic.h into apic.hIngo Molnar1-4/+310
Impact: cleanup Reduce the number of include files to worry about. Also, most of the users of APIC facilities had to include genapic.h already, which embedded apic.h, so the distinction was meaningless. [ include apic.h from genapic.h for compatibility. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86: fold apic_ops into genapicYinghai Lu1-66/+31
Impact: cleanup make it simpler, don't need have one extra struct. v2: fix the sgi_uv build Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-17x86: add x2apic configYinghai Lu1-3/+15
Impact: cleanup so could deselect x2apic and INTR_REMAP will select x2apic Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-11x86, apic: make generic_apic_probe() generally availableIngo Molnar1-0/+6
Impact: build fix Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-02-10x86: make apic_* operations inline functionsJeremy Fitzhardinge1-6/+29
Mainly to get proper type-checking and consistency. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
2009-01-29x86: remove subarchitecture supportIngo Molnar1-0/+2
Remove the 32-bit subarchitecture support code. All subarchitectures but Voyager have been converted. Voyager will be done later or will be removed. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: remove mach_apic.hIngo Molnar1-1/+1
Spread mach_apic.h definitions into genapic.h. (with some knock-on effects on smp.h and apic.h.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: remove mach_apicdef.hIngo Molnar1-0/+16
Move its definitions into apic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, smp: eliminate asm/mach-default/mach_wakecpu.hIngo Molnar1-0/+15
Spread mach_wakecpu.h's definitions into apic.h and genapic.h and remove mach_wakecpu.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-31x86: apic.c: xapic_icr_read and x2apic_icr_read should be staticJaswinder Singh Rajput1-1/+0

2008-11-11x86: call machine_shutdown and stop all CPUs in native_machine_haltIvan Vecera1-0/+1
Impact: really halt all CPUs on halt Function machine_halt (resp. native_machine_halt) is empty for x86 architectures. When command 'halt -f' is invoked, the message "System halted." is displayed but this is not really true because all CPUs are still running. There are also similar inconsistencies for other arches (some uses power-off for halt or forever-loop with IRQs enabled/disabled). IMO there should be used the same approach for all architectures OR what does the message "System halted" really mean? This patch fixes it for x86.

2008-10-23x86: Fix ASM_X86__ header guardsH. Peter Anvin1-3/+3
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
