* x86: unify genapic code, unify subarchitectures, remove old subarchitecture ↵Suresh Siddha2009-01-29
| | | | | | | | | code, xapic fix xapic fix for 32bit platform with less than 8 cpu's. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: move to the X86_32_NON_STANDARD code sectionIngo Molnar2009-01-29
| | | | | | | Make Voyager depend on X86_32_NON_STANDARD - it is a non-standard 32-bit SMP architecture. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: rename X86_GENERICARCH to X86_32_NON_STANDARDIngo Molnar2009-01-29
| | | | | | | | | X86_GENERICARCH is a misnomer - it contains non-PC 32-bit architectures that are not included in the default build. Rename it to X86_32_NON_STANDARD. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: remove the subarch menuIngo Molnar2009-01-29
| | | | | | Remove the subarch menu and standardize on X86_PC. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: move X86_VSMP from subarch menuIngo Molnar2009-01-29
| | | | | | | Move X86_VSMP out of the subarch menu - this way it can be enabled together with standard PC support as well, in the same kernel. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: move non-standard 32-bit platform Kconfig entriesIngo Molnar2009-01-29
| | | | | | | | | - make X86_GENERICARCH depend X86_NON_STANDARD - move X86_SUMMIT, X86_ES7000 and X86_BIGSMP out of the subarchitecture menu and under this option Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: move VOYAGER to the NON_STANDARD_PLATFORM sectionIngo Molnar2009-01-29
| | | | | | | Move X86_ELAN (old, NCR hw platform built on Intel CPUs) from the subarchitecture menu to the non-standard-platform section. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: move ELAN to the NON_STANDARD_PLATFORM sectionIngo Molnar2009-01-29
| | | | | | | Move X86_ELAN (old, AMD based web-boxes) from the subarchitecture menu to the non-standard-platform section. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: cleanup, introduce CONFIG_NON_STANDARD_PLATFORMSIngo Molnar2009-01-29
| | | | | | | | Introduce a Y/N Kconfig option for non-PC x86 platforms. Make VisWS, RDC321 and SGI/UV depend on this. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove ISA quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | | | | Voyager has this ISA quirk (because Voyager has no ISA support): config ISA bool "ISA support" depends on !X86_VOYAGER There's a ton of x86 hardware that does not support ISA, and because most ISA drivers cannot auto-detect in a safe way, the convention in the kernel has always been to not enable ISA drivers if they are not needed. Voyager users can do likewise - no need for a Kconfig quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove power management Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | | Voyager has this PM/ACPI Kconfig quirk: menu "Power management and ACPI options" depends on !X86_VOYAGER Most of the PM features are auto-detect so they should be safe to run on just about any hardware. (If not, those instances need fixing.) In any case, if a kernel is built for Voyager, the power management options can be disabled. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove HOTPLUG_CPU Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | Voyager has this Kconfig quirk: config HOTPLUG_CPU bool "Support for hot-pluggable CPUs" depends on SMP && HOTPLUG && !X86_VOYAGER But this exception will be moot once Voyager starts using the generic x86 code. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove MCE quirkIngo Molnar2009-01-29
| | | | | | | | | | If no MCE code is desired on Voyager hw then the solution is to turn them off in the .config - and to extend the MCE code to not initialize on Voyager. Remove the build-time quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove APIC/IO-APIC Kbuild quirkIngo Molnar2009-01-29
| | | | | | | The lapic/ioapic code properly auto-detects and is safe to run on CPUs that have no local APIC. (or which have their lapic turned off in the hardware) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove PARAVIRT Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | Remove this Kconfig quirk: config PARAVIRT bool "Enable paravirtualization code" depends on !X86_VOYAGER help Voyager support built into a kernel does not preclude paravirt support. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove KVM_GUEST quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | Voyager has this quirk currently: config KVM_GUEST bool "KVM Guest support" select PARAVIRT depends on !X86_VOYAGER Voyager support built into a kernel image does not exclude KVM paravirt guest support - so remove this quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove KVM_CLOCK quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | Voyager has this build-time quirk to exclude KVM_CLOCK: bool "KVM paravirtualized clock" select PARAVIRT select PARAVIRT_CLOCK depends on !X86_VOYAGER Voyager support built into a kernel image does not exclude KVM paravirt clock support - so remove this quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove VMI Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | x86/Voyager has this build-time quirk: bool "VMI Guest support" select PARAVIRT depends on X86_32 depends on !X86_VOYAGER Since VMI is auto-detected (and Voyager will be auto-detected) there's no reason for this quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/VisWS: remove Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | VisWS has this quirk currently: config X86_VISWS bool "SGI 320/540 (Visual Workstation)" depends on X86_32 && PCI && !X86_VOYAGER && X86_MPPARSE && PCI_GODIRECT The !Voyager quirk is unnecessary. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove X86_FIND_SMP_CONFIG Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | | x86/Voyager had this Kconfig quirk: config X86_FIND_SMP_CONFIG def_bool y depends on X86_MPPARSE || X86_VOYAGER Which splits off the find_smp_config() callback into a build-time quirk. Voyager should use the existing x86_quirks.mach_find_smp_config() callback to introduce SMP-config quirks. NUMAQ-32 and VISWS already use this. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove X86_BIOS_REBOOT Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | | Voyager has this Kconfig quirk: config X86_BIOS_REBOOT bool depends on !X86_VOYAGER default y Voyager should use the existing machine_ops.emergency_restart reboot quirk mechanism instead of a build-time quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove X86_HT Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | Voyager has this Kconfig quirk: depends on (X86_32 && !X86_VOYAGER) || X86_64 That is unnecessary as HT support is CPUID driven and explicitly enumerated. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: generalize boot_cpu_idIngo Molnar2009-01-29
| | | | | | | | x86/Voyager can boot on non-zero processors. While that can probably be fixed by properly remapping the physical CPU IDs, keep boot_cpu_id for now for easier transition - and expand it to all of x86. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: replace CONFIG_X86_SMP with CONFIG_SMPIngo Molnar2009-01-29
| | | | | | | | | | | | | | | | | The x86/Voyager subarch used to have this distinction between 'x86 SMP support' and 'Voyager SMP support': config X86_SMP bool depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64) This is a pointless distinction - Voyager can (and already does) use smp_ops to implement various SMP quirks it has - and it can be extended more to cover all the specialities of Voyager. So remove this complication in the Kconfig space. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove ARCH_SUSPEND_POSSIBLE Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | Voyager has this Kconfig quirk for suspend/resume: config ARCH_SUSPEND_POSSIBLE def_bool y depends on !X86_VOYAGER The proper mechanism to not suspend on a piece of hardware to disable CONFIG_SUSPEND. Remove the quirk. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove HIBERNATION Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | | Voyager has this hibernation quirk: config ARCH_HIBERNATION_POSSIBLE def_bool y depends on !SMP || !X86_VOYAGER Hibernation is a generic facility provided on all x86 platforms. If it is buggy on Voyager then that bug should be fixed - not worked around. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove KGDB Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | x86/Voyager has this KGDB quirk: select HAVE_ARCH_KGDB if !X86_VOYAGER This is completely pointless - there's nothing in KGDB that cannot work on Voyager. Remove it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove KVM Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | Voyager and other subarchitectures have this Kconfig quirk: select HAVE_KVM if ((X86_32 && !X86_VOYAGER && !X86_VISWS && !X86_NUMAQ) || X86_64) This is unnecessary, as KVM cleanly detects based on CPUID capabilities. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove NATSEMI Kconfig quirkIngo Molnar2009-01-29
| | | | | | | | | | | | x86/Voyager has this quirk for SCx200 support: config SCx200 tristate "NatSemi SCx200 support" depends on !X86_VOYAGER Remove it - Voyager users can disable drivers they dont need. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: remove MCA Kconfig quirkIngo Molnar2009-01-29
| | | | | | | Remove Voyager Kconfig quirk: just like any other hardware platform users of Voyager systems can configure in the hardware drivers they need. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: disable Voyager temporarilyIngo Molnar2009-01-29
| | | | | | | | | | | | x86/Voyager does not build right now and it's unclear whether it will be cleaned up and ported to the subarch-less 32-bit x86 code - so disable it for now. If it's fixed we'll re-enable it - or remove it after some time. There's a very low number of systems running development kernels on x86/Voyager currently. (one or two on the whole planet) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86/Voyager: clean up BROKEN Kconfig referenceIngo Molnar2009-01-29
| | | | | | | CONFIG_BROKEN has been removed from the upstream kernel years ago, but X86_VOYAGER still had a stale reference to it - remove it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: remove subarchitecture supportIngo Molnar2009-01-29
| | | | | | | | | 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>
* x86: move mach-default/*.h files to asm/Ingo Molnar2009-01-29
| | | | | | | | We are getting rid of subarchitecture support - move the hook files to asm/. (These are now stale and should be replaced with more explicit runtime mechanisms - but the transition is simpler this way.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: remove subarchitecture support codeIngo Molnar2009-01-29
| | | | | | | | Remove remaining bits of the subarchitecture code. Now that all the special platforms are runtime probed and runtime handled, we can remove these facilities. Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86, bigsmp: consolidate codeIngo Molnar2009-01-29
| | | | | | | | Move all code to arch/x86/kernel/bigsmp_32.c. With this it ceases to rely on any build-time subarch features. Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: remove mach_apic.hIngo Molnar2009-01-29
| | | | | | | 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>
