From 4c8c3c7f70a6779d30f5492acbc9978f4636fe7a Mon Sep 17 00:00:00 2001 From: Valentin Schneider Date: Tue, 7 Mar 2023 14:35:56 +0000 Subject: treewide: Trace IPIs sent via smp_send_reschedule() To be able to trace invocations of smp_send_reschedule(), rename the arch-specific definitions of it to arch_smp_send_reschedule() and wrap it into an smp_send_reschedule() that contains a tracepoint. Changes to include the declaration of the tracepoint were driven by the following coccinelle script: @func_use@ @@ smp_send_reschedule(...); @include@ @@ #include @no_include depends on func_use && !include@ @@ #include <...> + + #include [csky bits] [riscv bits] Signed-off-by: Valentin Schneider Signed-off-by: Peter Zijlstra (Intel) Acked-by: Guo Ren Acked-by: Palmer Dabbelt Link: https://lore.kernel.org/r/20230307143558.294354-6-vschneid@redhat.com --- arch/sparc/kernel/smp_32.c | 2 +- arch/sparc/kernel/smp_64.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/sparc') diff --git a/arch/sparc/kernel/smp_32.c b/arch/sparc/kernel/smp_32.c index ad8094d955eb..87eaa7719fa2 100644 --- a/arch/sparc/kernel/smp_32.c +++ b/arch/sparc/kernel/smp_32.c @@ -120,7 +120,7 @@ void cpu_panic(void) struct linux_prom_registers smp_penguin_ctable = { 0 }; -void smp_send_reschedule(int cpu) +void arch_smp_send_reschedule(int cpu) { /* * CPU model dependent way of implementing IPI generation targeting diff --git a/arch/sparc/kernel/smp_64.c b/arch/sparc/kernel/smp_64.c index a55295d1b924..e5964d1d8b37 100644 --- a/arch/sparc/kernel/smp_64.c +++ b/arch/sparc/kernel/smp_64.c @@ -1430,7 +1430,7 @@ static unsigned long send_cpu_poke(int cpu) return hv_err; } -void smp_send_reschedule(int cpu) +void arch_smp_send_reschedule(int cpu) { if (cpu == smp_processor_id()) { WARN_ON_ONCE(preemptible()); -- cgit v1.2.3
