* | x86, irq: Don't block IRQ0_VECTOR..IRQ15_VECTOR's on all cpu'sSuresh Siddha2010-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently IRQ0..IRQ15 are assigned to IRQ0_VECTOR..IRQ15_VECTOR's on all the cpu's. If these IRQ's are handled by legacy pic controller, then the kernel handles them only on cpu 0. So there is no need to block this vector space on all cpu's. Similarly if these IRQ's are handled by IO-APIC, then the IRQ affinity will determine on which cpu's we need allocate the vector resource for that particular IRQ. This can be done dynamically and here also there is no need to block 16 vectors for IRQ0..IRQ15 on all cpu's. Fix this by initially assigning IRQ0..IRQ15 to IRQ0_VECTOR..IRQ15_VECTOR's only on cpu 0. If the legacy controllers like pic handles these irq's, then this configuration will be fixed. If more modern controllers like IO-APIC handle these IRQ's, then we start with this configuration and as IRQ's migrate, vectors (/and cpu's) associated with these IRQ's change dynamically. This will freeup the block of 16 vectors on other cpu's which don't handle IRQ0..IRQ15, which can now be used for other IRQ's that the particular cpu handle.

|/ | | | | | | | | | | | | | FIRST_DEVICE_VECTOR is going away and it looks like a bad hack to steal FIRST_DEVICE_VECTOR / FIRST_EXTERNAL_VECTOR, when it looks like it needs IRQ0_VECTOR.

* x86: Move tsc_calibration to x86_init_opsThomas Gleixner2009-08-31
| | | | | | | | | | TSC calibration is modified by the vmware hypervisor and paravirt by separate means. Moorestown wants to add its own calibration routine as well. So make calibrate_tsc a proper x86_init_ops function and override it by paravirt or by the early setup of the vmware hypervisor. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The highlevel methods are now named: extern void x86_quirk_pre_intr_init(void); extern void x86_quirk_intr_init(void); extern void x86_quirk_trap_init(void); extern void x86_quirk_pre_time_init(void); extern void x86_quirk_time_init(void); This makes it clear that if some platform extension has to do something here that it is considered ... weird, and is discouraged. Also remove arch_hooks.h and move it into setup.h (and other header files where appropriate). Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | * | | x86: Add IRQF_TIMER to legacy x86 timer interrupt descriptorsLinus Torvalds2009-02-22
| | | |/ | | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now nobody cares, but the suspend/resume code will eventually want to suspend device interrupts without suspending the timer, and will depend on this flag to know. The modern x86 timer infrastructure uses the local APIC timers and never shows up as a device interrupt at all, so it isn't affected and doesn't need any of this. Cc: Rafael J.

| * 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: isolate PIC/PIT in/out callsAlan Cox2008-01-30
| | | | | | | | | | | | | | | | | Rather than remove and/or mangle inb_p/outb_p we want to remove the use of them from inappropriate places. For the PIC/PIT this may eventually depend on 32/64bitism or similar so start by adding inb/outb_pit and inb/outb_pic so that we can make them use any scheme we settle on without disturbing the existing, correct (for ISA), port 0x80 usage. (eg we can make inb_pit use udelay without messing up inb_p). Floppy already does this for the fdc. That really only leaves the CMOS as a core logic item to tackle, and bits of parallel port handling in the chipset layers.
