From e5198075c67a22ec9a09565b1ce88d3d3f5ba855 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Fri, 15 May 2009 13:05:16 -0700 Subject: x86, apic: introduce io_apic_irq_attr according to Ingo, io_apic irq-setup related functions have too many parameters with a repetitive signature. So reduce related funcs to get less params by passing a pointer to a newly defined io_apic_irq_attr structure. v2: io_apic_irq ==> irq_attr triggering ==> trigger v3: add set_io_apic_irq_attr [ Impact: cleanup ] Signed-off-by: Yinghai Lu Cc: Andrew Morton Cc: Jesse Barnes Cc: Len Brown LKML-Reference: <4A08ACD3.2070401@kernel.org> Signed-off-by: Ingo Molnar --- arch/x86/kernel/acpi/boot.c | 22 ++++++++++++---------- 1 file changed, 12 insertions(+), 10 deletions(-) (limited to 'arch/x86/kernel/acpi') diff --git a/arch/x86/kernel/acpi/boot.c b/arch/x86/kernel/acpi/boot.c index dcfbc3ab9e4..4af63dfb0f0 100644 --- a/arch/x86/kernel/acpi/boot.c +++ b/arch/x86/kernel/acpi/boot.c @@ -523,7 +523,7 @@ int acpi_gsi_to_irq(u32 gsi, unsigned int *irq) * success: return IRQ number (>=0) * failure: return < 0 */ -int acpi_register_gsi(struct device *dev, u32 gsi, int triggering, int polarity) +int acpi_register_gsi(struct device *dev, u32 gsi, int trigger, int polarity) { unsigned int irq; unsigned int plat_gsi = gsi; @@ -533,14 +533,14 @@ int acpi_register_gsi(struct device *dev, u32 gsi, int triggering, int polarity) * Make sure all (legacy) PCI IRQs are set as level-triggered. */ if (acpi_irq_model == ACPI_IRQ_MODEL_PIC) { - if (triggering == ACPI_LEVEL_SENSITIVE) + if (trigger == ACPI_LEVEL_SENSITIVE) eisa_set_level_irq(gsi); } #endif #ifdef CONFIG_X86_IO_APIC if (acpi_irq_model == ACPI_IRQ_MODEL_IOAPIC) { - plat_gsi = mp_register_gsi(dev, gsi, triggering, polarity); + plat_gsi = mp_register_gsi(dev, gsi, trigger, polarity); } #endif acpi_gsi_to_irq(plat_gsi, &irq); @@ -1156,7 +1156,7 @@ void __init mp_config_acpi_legacy_irqs(void) } } -static int mp_config_acpi_gsi(struct device *dev, u32 gsi, int triggering, +static int mp_config_acpi_gsi(struct device *dev, u32 gsi, int trigger, int polarity) { #ifdef CONFIG_X86_MPPARSE @@ -1181,7 +1181,7 @@ static int mp_config_acpi_gsi(struct device *dev, u32 gsi, int triggering, /* print the entry should happen on mptable identically */ mp_irq.type = MP_INTSRC; mp_irq.irqtype = mp_INT; - mp_irq.irqflag = (triggering == ACPI_EDGE_SENSITIVE ? 4 : 0x0c) | + mp_irq.irqflag = (trigger == ACPI_EDGE_SENSITIVE ? 4 : 0x0c) | (polarity == ACPI_ACTIVE_HIGH ? 1 : 3); mp_irq.srcbus = number; mp_irq.srcbusirq = (((devfn >> 3) & 0x1f) << 2) | ((pin - 1) & 3); @@ -1194,10 +1194,11 @@ static int mp_config_acpi_gsi(struct device *dev, u32 gsi, int triggering, return 0; } -int mp_register_gsi(struct device *dev, u32 gsi, int triggering, int polarity) +int mp_register_gsi(struct device *dev, u32 gsi, int trigger, int polarity) { int ioapic; int ioapic_pin; + struct io_apic_irq_attr irq_attr; if (acpi_irq_model != ACPI_IRQ_MODEL_IOAPIC) return gsi; @@ -1225,11 +1226,12 @@ int mp_register_gsi(struct device *dev, u32 gsi, int triggering, int polarity) ioapic_pin); return gsi; } - mp_config_acpi_gsi(dev, gsi, triggering, polarity); + mp_config_acpi_gsi(dev, gsi, trigger, polarity); - io_apic_set_pci_routing(dev, ioapic, ioapic_pin, gsi, - triggering == ACPI_EDGE_SENSITIVE ? 0 : 1, - polarity == ACPI_ACTIVE_HIGH ? 0 : 1); + set_io_apic_irq_attr(&irq_attr, ioapic, ioapic_pin, + trigger == ACPI_EDGE_SENSITIVE ? 0 : 1, + polarity == ACPI_ACTIVE_HIGH ? 0 : 1); + io_apic_set_pci_routing(dev, gsi, &irq_attr); return gsi; } -- cgit v1.2.3
