lib, traceevent: add PRINT_HEX_STR variant

2017-01-25T18:17:47+00:00

Add support for the __print_hex_str() macro that was added for
tracing, so that user space tools such as perf can understand
it as well.

tools lib traceevent: Add retrieval of preempt count and latency flags

2016-11-23T13:44:03+00:00

Add a way to retrieve the preempt count as well as the latency flags from a
pevent_record.

  int pevent_data_preempt_count(pevent, record);

returns the preempt count of a record.

  int pevent_data_flags(pevent, record);

returns the latency flags for a record.

tools lib traceevent: Use USECS_PER_SEC instead of hardcoded number

2016-11-23T13:44:02+00:00

Instead of using 1000000, use the define in time64.h instead.

Also remove the the duplicate defines for NSECS_PER_SEC.

tools lib traceevent: Add correct header for ipv6 definitions

2016-07-14T14:33:32+00:00

We need to include netinet/in.h to get the in6_addr struct definition, needed to
build it on the Android NDK:

  In file included from event-parse.c:36:0:
  /home/acme/android/android-ndk-r12/platforms/android-24/arch-arm/usr/include/netinet/ip6.h:82:18: error: field 'ip6_src' has incomplete type
    struct in6_addr ip6_src; /* source address */

And it is the canonical way of getting IPv6 definitions, as described,
for instance, in Linux's 'man ipv6'

Doing that uncovers another problem: this source file uses PRIu64 but
doesn't include it, depending on it being included by chance via the now
replaced header (netinet/ip6.h), fix it.

tools lib traceevent: Use str_error_r()

2016-07-12T18:20:28+00:00

To make it portable to non-glibc systems, that follow the XSI variant
instead of the GNU specific one that gets in place when _GNU_SOURCE is
defined.

tools lib traceevent: Remove redundant CPU output

2016-03-23T18:08:12+00:00

Commit a6745330789f ("tools lib traceevent: Split pevent_print_event()
into specific functionality functions") broke apart the function
pevent_print_event() into three functions.

The first function prints the comm, pid and CPU, the second prints the
timestamp.

But that commit added the printing of the CPU in the timestamp function,
which now causes pevent_print_event() to duplicate the CPU output.

Remove the redundant printing of the record's CPU from the timestamp
function.

tools lib traceevent: Add '~' operation within arg_num_eval()

2016-03-10T19:27:41+00:00

When evaluating values for print flags, if the value included a '~'
operator, the parsing would fail. This broke kmalloc's parsing of:

__print_flags(REC->gfp_flags, "|", {(unsigned
long)((((((( gfp_t)(0x400000u|0x2000000u)) | (( gfp_t)0x40u) |
(( gfp_t)0x80u) | (( gfp_t)0x20000u)) | (( gfp_t)0x02u)) |
(( gfp_t)0x08u)) | (( gfp_t)0x4000u) | (( gfp_t)0x10000u) |
(( gfp_t)0x1000u) | (( gfp_t)0x200u)) & ~(( gfp_t)0x2000000u))
                                        ^
                                        |

tools lib traceevent: Fix output of %llu for 64 bit values read on 32 bit machines

2016-03-03T14:10:38+00:00

When a long value is read on 32 bit machines for 64 bit output, the
parsing needs to change "%lu" into "%llu", as the value is read
natively.

Unfortunately, if "%llu" is already there, the code will add another "l"
to it and fail to parse it properly.
