These page faults - are currently handled in much the same way as the x86 shadow paging - based MMU, however the ordering of some operations is slightly - different. Future patches will add eager NX splitting, a fast page fault - handler, and parallel page faults. - - Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell - machine. This series introduced no new failures. - -Upstream-Status: Backport - -Signed-off-by: Michael Jeanson <mjeanson@efficios.com> -Signed-off-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> -Change-Id: Ie56959cb6c77913d2f1188b0ca15da9114623a4e ---- - .../lttng-module/arch/x86/kvm/mmutrace.h | 20 ++++++++++++++++++- - probes/lttng-probe-kvm-x86-mmu.c | 5 +++++ - 2 files changed, 24 insertions(+), 1 deletion(-) - -diff --git a/instrumentation/events/lttng-module/arch/x86/kvm/mmutrace.h b/instrumentation/events/lttng-module/arch/x86/kvm/mmutrace.h -index e5470400..86717835 100644 ---- a/instrumentation/events/lttng-module/arch/x86/kvm/mmutrace.h -+++ b/instrumentation/events/lttng-module/arch/x86/kvm/mmutrace.h -@@ -163,7 +163,25 @@ LTTNG_TRACEPOINT_EVENT_INSTANCE(kvm_mmu_page_class, kvm_mmu_prepare_zap_page, - TP_ARGS(sp) - ) - --#if (LINUX_VERSION_CODE >= KERNEL_VERSION(3,11,0)) -+#if (LINUX_VERSION_CODE >= KERNEL_VERSION(5,10,0)) -+ -+LTTNG_TRACEPOINT_EVENT_MAP( -+ mark_mmio_spte, -+ -+ kvm_mmu_mark_mmio_spte, -+ -+ TP_PROTO(u64 *sptep, gfn_t gfn, u64 spte), -+ TP_ARGS(sptep, gfn, spte), -+ -+ TP_FIELDS( -+ ctf_integer_hex(void *, sptep, sptep) -+ ctf_integer(gfn_t, gfn, gfn) -+ ctf_integer(unsigned, access, spte & ACC_ALL) -+ ctf_integer(unsigned int, gen, get_mmio_spte_generation(spte)) -+ ) -+) -+ -+#elif (LINUX_VERSION_CODE >= KERNEL_VERSION(3,11,0)) - - LTTNG_TRACEPOINT_EVENT_MAP( - mark_mmio_spte, -diff --git a/probes/lttng-probe-kvm-x86-mmu.c b/probes/lttng-probe-kvm-x86-mmu.c -index 8f981865..5043c776 100644 ---- a/probes/lttng-probe-kvm-x86-mmu.c -+++ b/probes/lttng-probe-kvm-x86-mmu.c -@@ -31,6 +31,11 @@ - #include <../../arch/x86/kvm/mmutrace.h> - #endif - -+#if (LINUX_VERSION_CODE >= KERNEL_VERSION(5,10,0)) -+#include <../arch/x86/kvm/mmu.h> -+#include <../arch/x86/kvm/mmu/spte.h> -+#endif -+ - #undef TRACE_INCLUDE_PATH - #undef TRACE_INCLUDE_FILE - --- -2.19.1 - |
