So that the function can be called from other files without adding prototypes to each of them. Signed-off-by: Roger Pau Monné <roger.pau@xxxxxxxxxx> --- Cc: Jan Beulich <jbeulich@xxxxxxxx> Cc: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> --- Changes since v1: - Add io_ prefix to avoid confusion. - Make the parameter unsigned. --- xen/arch/x86/io_apic.c | 4 +--- xen/arch/x86/mpparse.c | 2 +- xen/include/asm-x86/io_apic.h | 3 +++ 3 files changed, 5 insertions(+), 4 deletions(-) diff --git a/xen/arch/x86/io_apic.c b/xen/arch/x86/io_apic.c index 24ee431b00..d18046067c 100644 --- a/xen/arch/x86/io_apic.c +++ b/xen/arch/x86/io_apic.c @@ -2274,8 +2274,6 @@ static int ioapic_physbase_to_id(unsigned long physbase) return -EINVAL; } -unsigned apic_gsi_base(int apic); - static int apic_pin_2_gsi_irq(int apic, int pin) { int idx; @@ -2286,7 +2284,7 @@ static int apic_pin_2_gsi_irq(int apic, int pin) idx = find_irq_entry(apic, pin, mp_INT); return idx >= 0 ? pin_2_irq(idx, apic, pin) - : apic_gsi_base(apic) + pin; + : io_apic_gsi_base(apic) + pin; } int ioapic_guest_read(unsigned long physbase, unsigned int reg, u32 *pval) diff --git a/xen/arch/x86/mpparse.c b/xen/arch/x86/mpparse.c index 1eb7c99ea7..efcbc6115d 100644 --- a/xen/arch/x86/mpparse.c +++ b/xen/arch/x86/mpparse.c @@ -913,7 +913,7 @@ unsigned __init highest_gsi(void) return res; } -unsigned apic_gsi_base(int apic) +unsigned int io_apic_gsi_base(unsigned int apic) { return mp_ioapic_routing[apic].gsi_base; } diff --git a/xen/include/asm-x86/io_apic.h b/xen/include/asm-x86/io_apic.h index 225edd63b2..8029c8f400 100644 --- a/xen/include/asm-x86/io_apic.h +++ b/xen/include/asm-x86/io_apic.h @@ -127,6 +127,9 @@ struct __packed IO_APIC_route_entry { /* I/O APIC entries */ extern struct mpc_config_ioapic mp_ioapics[MAX_IO_APICS]; +/* Base GSI for this IO APIC */ +unsigned int io_apic_gsi_base(unsigned int apic); + /* Only need to remap ioapic RTE (reg: 10~3Fh) */ #define ioapic_reg_remapped(reg) (iommu_intremap && ((reg) >= 0x10)) -- 2.12.1 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
