From de93410310952fb7b705f784ef22493c8362dbe8 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 20 Aug 2009 09:27:29 +0200 Subject: x86: Move ioapic_ids_setup to x86_init_ops 32bit and also the numaq code have special requirements on the ioapic_id setup. Convert it to a x86_init_ops function and get rid of the quirks and #ifdefs Signed-off-by: Thomas Gleixner diff --git a/arch/x86/include/asm/io_apic.h b/arch/x86/include/asm/io_apic.h index 330ee80..2b8aeb8 100644 --- a/arch/x86/include/asm/io_apic.h +++ b/arch/x86/include/asm/io_apic.h @@ -177,12 +177,13 @@ extern int setup_ioapic_entry(int apic, int irq, int polarity, int vector, int pin); extern void ioapic_write_entry(int apic, int pin, struct IO_APIC_route_entry e); +extern void setup_ioapic_ids_from_mpc(void); #else /* !CONFIG_X86_IO_APIC */ #define io_apic_assign_pci_irqs 0 +#define setup_ioapic_ids_from_mpc x86_init_noop static const int timer_through_8259 = 0; static inline void ioapic_init_mappings(void) { } static inline void ioapic_insert_resources(void) { } - static inline void probe_nr_irqs_gsi(void) { } #endif diff --git a/arch/x86/include/asm/setup.h b/arch/x86/include/asm/setup.h index bbf2dfd..cc8b4b0 100644 --- a/arch/x86/include/asm/setup.h +++ b/arch/x86/include/asm/setup.h @@ -30,7 +30,6 @@ struct x86_quirks { void (*mpc_oem_pci_bus)(struct mpc_bus *m); void (*smp_read_mpc_oem)(struct mpc_oemtable *oemtable, unsigned short oemsize); - int (*setup_ioapic_ids)(void); }; extern void x86_quirk_intr_init(void); diff --git a/arch/x86/include/asm/x86_init.h b/arch/x86/include/asm/x86_init.h index 10b297b..6598573 100644 --- a/arch/x86/include/asm/x86_init.h +++ b/arch/x86/include/asm/x86_init.h @@ -4,9 +4,11 @@ /** * struct x86_init_mpparse - platform specific mpparse ops * @mpc_record: platform specific mpc record accounting + * @setup_ioapic_ids: platform specific ioapic id override */ struct x86_init_mpparse { void (*mpc_record)(unsigned int mode); + void (*setup_ioapic_ids)(void); }; /** diff --git a/arch/x86/kernel/apic/io_apic.c b/arch/x86/kernel/apic/io_apic.c index d2ed6c5..5f46871 100644 --- a/arch/x86/kernel/apic/io_apic.c +++ b/arch/x86/kernel/apic/io_apic.c @@ -2014,7 +2014,7 @@ void disable_IO_APIC(void) * by Matt Domsch Tue Dec 21 12:25:05 CST 1999 */ -static void __init setup_ioapic_ids_from_mpc(void) +void __init setup_ioapic_ids_from_mpc(void) { union IO_APIC_reg_00 reg_00; physid_mask_t phys_id_present_map; @@ -2023,9 +2023,8 @@ static void __init setup_ioapic_ids_from_mpc(void) unsigned char old_id; unsigned long flags; - if (x86_quirks->setup_ioapic_ids && x86_quirks->setup_ioapic_ids()) + if (acpi_ioapic) return; - /* * Don't check I/O APIC IDs for xAPIC systems.
