From b5fe363b7d89577fcfda9b6cf0efc32760bbccc6 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 18 Nov 2008 08:14:14 -0800 Subject: x86: use update_genapic to get rid of ES7000_CLUSTERED_APIC v2 Impact: clean up We can autodetect those system that need cluster apic, and update genapic accordingly. We can also remove wakeup.h for e7000, because it's default one is now the same as overall default mach_wakecpu.h Signed-off-by: Yinghai Lu Signed-off-by: Ingo Molnar --- arch/x86/kernel/es7000_32.c | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) (limited to 'arch/x86/kernel/es7000_32.c') diff --git a/arch/x86/kernel/es7000_32.c b/arch/x86/kernel/es7000_32.c index fb3bfe6..71d7be6 100644 --- a/arch/x86/kernel/es7000_32.c +++ b/arch/x86/kernel/es7000_32.c @@ -38,6 +38,7 @@ #include #include #include +#include #include #include #include @@ -163,7 +164,6 @@ es7000_rename_gsi(int ioapic, int gsi) return gsi; } -#ifdef CONFIG_ES7000_CLUSTERED_APIC static int wakeup_secondary_cpu_via_mip(int cpu, unsigned long eip) { unsigned long vect = 0, psaival = 0; @@ -182,13 +182,24 @@ static int wakeup_secondary_cpu_via_mip(int cpu, unsigned long eip) return 0; } +static void noop_wait_for_deassert(atomic_t *deassert_not_used) +{ +} + static int __init es7000_update_genapic(void) { genapic->wakeup_cpu = wakeup_secondary_cpu_via_mip; + /* MPENTIUMIII */ + if (boot_cpu_data.x86 == 6 && + (boot_cpu_data.x86_model >= 7 || boot_cpu_data.x86_model <= 11)) { + es7000_update_genapic_to_cluster(); + genapic->wait_for_init_deassert = noop_wait_for_deassert; + genapic->wakeup_cpu = wakeup_secondary_cpu_via_mip; + } + return 0; } -#endif void __init setup_unisys(void) @@ -206,9 +217,7 @@ setup_unisys(void) es7000_plat = ES7000_CLASSIC; ioapic_renumber_irq = es7000_rename_gsi; -#ifdef CONFIG_ES7000_CLUSTERED_APIC x86_quirks->update_genapic = es7000_update_genapic; -#endif } /* -- cgit v1.1
