From eda3913bb70ecebac13adccffe1e7f96e93cee02 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 15 Jul 2011 12:34:09 -0600 Subject: perf tools: Fix endian conversion reading event attr from file header The perf_event_attr struct has two __u32's at the top and they need to be swapped individually. With this change I was able to analyze a perf.data collected in a 32-bit PPC VM on an x86 system. I tested both 32-bit and 64-bit binaries for the Intel analysis side; both read the PPC perf.data file correctly. -v2: - changed the existing perf_event__attr_swap() to swap only elements of perf_event_attr and exported it for use in swapping the attributes in the file header - updated swap_ops used for processing events Signed-off-by: David Ahern Acked-by: Frederic Weisbecker Cc: acme@ghostprotocols.net Cc: peterz@infradead.org Cc: paulus@samba.org Cc: Link: http://lkml.kernel.org/r/1310754849-12474-1-git-send-email-dsahern@gmail.com Signed-off-by: Ingo Molnar --- tools/perf/util/session.h | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/perf/util/session.h') diff --git a/tools/perf/util/session.h b/tools/perf/util/session.h index 5de754f4b7f3..170601e67d6b 100644 --- a/tools/perf/util/session.h +++ b/tools/perf/util/session.h @@ -112,6 +112,7 @@ int perf_session__set_kallsyms_ref_reloc_sym(struct map **maps, u64 addr); void mem_bswap_64(void *src, int byte_size); +void perf_event__attr_swap(struct perf_event_attr *attr); int perf_session__create_kernel_maps(struct perf_session *self); -- cgit v1.2.3
