From c9b263d2be9c535b410f6617710534f798bf0ff0 Mon Sep 17 00:00:00 2001 From: Xiao Guangrong Date: Mon, 1 Nov 2010 16:58:43 +0800 Subject: KVM: fix tracing kvm_try_async_get_page Tracing 'async' and *pfn is useless, since 'async' is always true, and '*pfn' is always "fault_pfn' We can trace 'gva' and 'gfn' instead, it can help us to see the life-cycle of an async_pf Signed-off-by: Xiao Guangrong Signed-off-by: Marcelo Tosatti --- include/trace/events/kvm.h | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'include/trace') diff --git a/include/trace/events/kvm.h b/include/trace/events/kvm.h index c86f4e8e0bc9..d94d6c312ca1 100644 --- a/include/trace/events/kvm.h +++ b/include/trace/events/kvm.h @@ -218,18 +218,20 @@ TRACE_EVENT(kvm_age_page, #ifdef CONFIG_KVM_ASYNC_PF TRACE_EVENT( kvm_try_async_get_page, - TP_PROTO(bool async, u64 pfn), - TP_ARGS(async, pfn), + TP_PROTO(u64 gva, u64 gfn), + TP_ARGS(gva, gfn), TP_STRUCT__entry( - __field(__u64, pfn) + __field(u64, gva) + __field(u64, gfn) ), TP_fast_assign( - __entry->pfn = (!async) ? pfn : (u64)-1; + __entry->gva = gva; + __entry->gfn = gfn; ), - TP_printk("pfn %#llx", __entry->pfn) + TP_printk("gva = %#llx, gfn = %#llx", __entry->gva, __entry->gfn) ); TRACE_EVENT( -- cgit v1.2.3
