When executing the daemon test on Arm64 and x86 with Debian (Buster)
distro, both skip the test case with the log:
# ./perf test -v 76
76: daemon operations :
--- start ---
test child forked, pid 11687
test daemon list
trap: SIGINT: bad trap
./tests/shell/daemon.sh: 173: local: cpu-clock: bad variable name
test child finished with -2
---- end ----
daemon operations: Skip
So the error happens for the variable expansion when use local variable
in the shell script. Since Debian Buster uses dash but not bash as
non-interactive shell, when execute the daemon testing, it hits a known
issue for dash which was reported [1].
To resolve this issue, one option is to add double quotes for all local
variables assignment, so need to change the code from:
local line=`perf daemon --config ${config} -x: | head -2 | tail -1`
... to:
local line="`perf daemon --config ${config} -x: | head -2 | tail -1`"
But the testing script has bunch of local variables, this leads to big
changes for whole script.
On the other hand, the testing script asks to use the "local" feature
which is bash-specific, so this patch explicitly uses "#!/bin/bash" to
ensure running the script with bash.
After:
# ./perf test -v 76
76: daemon operations :
--- start ---
test child forked, pid 11329
test daemon list
test daemon reconfig

---- end ----

For some time now the 'perf test 42: BPF filter' returns an error on bpf
relocation subtest, at least on x86 and s390. This is caused by
d859900c4c ("bpf, libbpf: support global data/bss/rodata sections")
which introduces support for global variables in eBPF programs.
Perf test 42.4 checks that the eBPF relocation fails when the eBPF program
contains a global variable. It returns OK when the eBPF program
could not be loaded and FAILED otherwise.
With above commit the test logic for the eBPF relocation is obsolete.
The loading of the eBPF now succeeds and the test always shows FAILED.
This patch removes the sub test completely.
Also a lot of eBPF program testing is done in the eBPF test suite,
it also contains tests for global variables.
Output before:
42: BPF filter :
42.1: Basic BPF filtering : Ok
42.2: BPF pinning : Ok
42.3: BPF prologue generation : Ok
42.4: BPF relocation checker : Failed
#
Output after:
# ./perf test -F 42
42: BPF filter :
42.1: Basic BPF filtering : Ok
42.2: BPF pinning : Ok
42.3: BPF prologue generation : Ok

The commit fbefe9c2f8 ("perf tools: Support arch specific
PERF_SAMPLE_WEIGHT_STRUCT processing") changes the ins_lat to a
model-specific variable only for X86, but perf test still verify the
variable in the generic test.
Remove the ins_lat check in the generic test. The following patch will
add it in the X86 specific test.

A previous commit fixed the bug that left it out of the list. This adds

The CoreSight testing contains sub cases, e.g. every CPU iterates the
possible conntected sinks and tests the paths between the associated ETM
with the found sink. Besides the per-thread testing, it also contains
system wide testing and snapshot testing.
To easier observe results for the sub cases, this patch introduces a new
function arm_cs_report(), it outputs the result as "PASS" or "FAIL" for
every sub case; and it records the error in the variable "glb_err" which
is used as the final return value when exits the testing.

With the option '-v' for the verbose logs, "perf test" outputs tons of
logs for the CoreSight case, the logs are mainly introduced by the
decoding. And it outputs some trivial info from "perf record" command
and there have debugging info for CPU number and device name when
iterates between ETMs and sinks.
For a neat output format, this patch redirects the output logs to
"/dev/null", thus can avoid to flood logs. And it removes the redundant
log for CPU number and device name, which have already printed out the
relevant info in the function record_touch_file().

The ubsan reported the following error. It was because sample's raw

The raw data contains an u32 size prefix so the data size should have
an u32 padding after 8-byte aligned data.

A separate field isn't strictly required. The core field could be
re-used for thread IDs as a single field was used previously.
But separating them will avoid confusion and catch potential errors
where core IDs are read as thread IDs and vice versa.
Also remove the placeholder id field which is now no longer used.

Add socket as a separate member so that it doesn't have to be packed
into the int value.
When the socket ID was larger than 8 bits the output appeared corrupted
or incomplete.
For example, here on ThunderX2 'perf stat' reports a socket of -1 and an
invalid die number:
./perf stat -a --per-die
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized
...
S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized
...
And with --per-core there is an entry with an invalid core ID:
./perf stat record -a --per-core
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized
...
S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized
...
This fixes the "Session topology" self test on ThunderX2.
After this fix the output contains the correct socket and die IDs and no
longer prints a warning about the size of the socket ID:
./perf stat --per-die -a
Performance counter stats for 'system wide':
S36-D0 128 169,869.39 msec cpu-clock # 127.501 CPUs utilized

Commit e1c92a7fbb ("perf tests: Add another metric parsing test") add
another test for metric parsing. The test goes through all metrics
compiled for arch within pmu events and try to parse them.
Right now this test is failing in powerpc machine.
Result in power9 platform:
[command]# ./perf test 10
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Skip (some metrics failed)
10.4: Parsing of PMU event table metrics with fake PMUs : FAILED!
Issue is we are passing different runtime parameter value in
"expr__find_other" and "expr__parse" function which is called from
function `metric_parse_fake`. And because of this parsing of hv-24x7
metrics is failing.
[command]# ./perf test 10 -vv
.....
hv_24x7/pm_mcs01_128b_rd_disp_port01,chip=1/ not found
expr__parse failed
test child finished with -1
---- end ----
PMU events subtest 4: FAILED!
This patch fix this issue and change runtime parameter value to '0' in
expr__parse function.

10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
