fcee7de608 arm64: defconfig: Enable CPU clock drivers for Qualcomm msm8916
QCOM_A53PLL and QCOM_CLK_APCS_MSM8916 used to be enabled by default in
drivers/clk/qcom/Kconfig. A recent patch changed that by dropping the
'default ARCH_QCOM' directive.

Add the two options explicitly in the arm64 defconfig, to avoid
functional regressions.

be6cef69ba net: aquantia: fix out of memory condition on rx side
On embedded environments with hard memory limits it is a normal although
rare case when skb can't be allocated on rx part under high traffic.

In such OOM cases napi_complete_done() was not called.
So the napi object became in an invalid state like it is "scheduled".
Kernel do not re-schedules the poll of that napi object.

Consequently, kernel can not remove that object the system hangs on
`ifconfig down` waiting for a poll.

We are fixing this by gracefully closing napi poll routine with correct
invocation of napi_complete_done.

This was reproduced with artificially failing the allocation of skb to
simulate an "out of memory" error case and check that traffic does
not get stuck.

5c47e3ba6f net: aquantia: linkstate irq should be oneshot
Declaring threaded irq handler should also indicate the irq is
oneshot. It is oneshot indeed, because HW implements irq automasking
on trigger.

Not declaring this causes some kernel configurations to fail
on interface up, because request_threaded_irq returned an err code.

The issue was originally hidden on normal x86_64 configuration with
latest kernel, because depending on interrupt controller, irq driver
added ONESHOT flag on its own.

Issue was observed on older kernels (4.14) where no such logic exists.

Fix issues in tc-taprio and tc-cbs

This series fixes one panic and one WARN_ON found in the tc-taprio
qdisc, while trying to apply it:

The tc-cbs was also visually found to suffer of the same issue as
tc-taprio, and the fix was only compile-tested in that case.

f04b514c0c taprio: Set default link speed to 10 Mbps in taprio_set_picos_per_byte
The taprio budget needs to be adapted at runtime according to interface
link speed. But that handling is problematic.

For one thing, installing a qdisc on an interface that doesn't have
carrier is not illegal. But taprio prints the following stack trace:

This happens because the qdisc ->dequeue callback gets called. Which
again is not illegal, the qdisc will dequeue even when the interface is
up but doesn't have carrier (and hence SPEED_UNKNOWN), and the frames
will be dropped further down the stack in dev_direct_xmit().

And, at the end of the day, for what? For calculating the initial budget
of an interface which is non-operational at the moment and where frames
will get dropped anyway.

So if we can't figure out the link speed, default to SPEED_10 and move
along. We can also remove the runtime check now.

efb55222d3 taprio: Fix kernel panic in taprio_destroy
taprio_init may fail earlier than this line:

	list_add(&q->taprio_list, &taprio_list);

i.e. due to the net device not being multi queue.

Attempting to remove q from the global taprio_list when it is not part
of it will result in a kernel panic.

Fix it by matching list_add and list_del better to one another in the
order of operations. This way we can keep the deletion unconditional
and with lower complexity - O(1).

00a263902a perf intel-pt: Use shared x86 insn decoder
Now that there's a common version of the decoder for all tools, use it
instead of the local copy.

Also use perf's check-headers.sh script to diff the decoder files to
make sure they remain in sync with the kernel version.  Objtool has a
similar check.

Committer notes:

Had to keep this all pointing explicitely to x86 headers/files, i.e.
instead of asm/isnn.h we had to use ../include/asm/insn.h when the files
were in differemt dirs, or just replace "<asm/foo.h>" with "foo.h".

This way we continue to be able to process perf.data files with Intel PT
traces in distros other than x86.

Also fixed up the awk script paths to use $(srcdir)/tools/arch instead
or relative directories so that we keep detached tarballs (make help |
grep perf) working.

For now the include lines in these headers are being ignored so as not
to flag false reports of kernel/tools out of sync.

58993fb2c5 perf: Update .gitignore file
After a "make tools/perf", git reports the following untracked files:

  tools/perf/feature/
  tools/perf/fixdep
  tools/perf/libtraceevent-dynamic-list

Add these generated files to perf's .gitignore file.

d046b72548 objtool: Move x86 insn decoder to a common location
The kernel tree has three identical copies of the x86 instruction
decoder.  Two of them are in the tools subdir.

The tools subdir is supposed to be completely standalone and separate
from the kernel.  So having at least one copy of the kernel decoder in
the tools subdir is unavoidable.  However, we don't need *two* of them.

Move objtool's copy of the decoder to a shared location, so that perf
will also be able to use it.

f01642e491 perf metricgroup: Support multiple events for metricgroup
Some uncore metrics don't work as expected. For example, on
cascadelakex:

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1

   Performance counter stats for 'system wide':

           1841092      unc_m_pmm_rpq_inserts
           3680816      unc_m_pmm_wpq_inserts

       1.001775055 seconds time elapsed

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1

   Performance counter stats for 'system wide':

         860649746      unc_m_pmm_rpq_occupancy.all
           1840557      unc_m_pmm_rpq_inserts
       12790627455      unc_m_clockticks

       1.001773348 seconds time elapsed

No metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' or 'UNC_M_PMM_READ_LATENCY' are
reported.

The issue is, the case of an alias expanding to mulitple events is not
supported, typically the uncore events.  (see comments in
find_evsel_group()).

For UNC_M_PMM_BANDWIDTH.TOTAL in above example, the expanded event group
is '{unc_m_pmm_rpq_inserts,unc_m_pmm_wpq_inserts}:W', but the actual
events passed to find_evsel_group are:

  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_rpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts
  unc_m_pmm_wpq_inserts

For this multiple events case, it's not supported well.

This patch introduces a new field 'metric_leader' in struct evsel. The
first event is considered as a metric leader. For the rest of same
events, they point to the first event via it's metric_leader field in
struct evsel.

This design is for adding the counting results of all same events to the
first event in group (the metric_leader).

With this patch,

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_BANDWIDTH.TOTAL -a -- sleep 1

   Performance counter stats for 'system wide':

           1842108      unc_m_pmm_rpq_inserts     #    337.2 MB/sec  UNC_M_PMM_BANDWIDTH.TOTAL
           3682209      unc_m_pmm_wpq_inserts

       1.001819706 seconds time elapsed

  root@lkp-csl-2sp2:~# perf stat -M UNC_M_PMM_READ_LATENCY -a -- sleep 1

   Performance counter stats for 'system wide':

         861970685      unc_m_pmm_rpq_occupancy.all #    219.4 ns  UNC_M_PMM_READ_LATENCY
           1842772      unc_m_pmm_rpq_inserts
       12790196356      unc_m_clockticks

       1.001749103 seconds time elapsed

Now we can see the correct metrics 'UNC_M_PMM_BANDWIDTH.TOTAL' and
'UNC_M_PMM_READ_LATENCY'.

287f2649f7 perf metricgroup: Scale the metric result
Some metrics define the scale unit, such as

    {
        "BriefDescription": "Intel Optane DC persistent memory read latency (ns). Derived from unc_m_pmm_rpq_occupancy.all",
        "Counter": "0,1,2,3",
        "EventCode": "0xE0",
        "EventName": "UNC_M_PMM_READ_LATENCY",
        "MetricExpr": "UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS",
        "MetricName": "UNC_M_PMM_READ_LATENCY",
        "PerPkg": "1",
        "ScaleUnit": "6000000000ns",
        "UMask": "0x1",
        "Unit": "iMC"
    },

For above example, the ratio should be,

ratio = (UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS) * 6000000000

But in current code, the ratio is not scaled ( * 6000000000)

With this patch, the ratio is scaled and the unit (ns) is printed.

For example,
  #    219.4 ns  UNC_M_PMM_READ_LATENCY

a55ab7c4ca perf pmu: Change convert_scale from static to global
The function convert_scale() can be used to convert string to unit and
scale. For example,

  s = "6000000000ns";
  convert_scale(s, &unit, &scale);

unit = "ns", scale = 6000000000.

Currently this function is static. This patch renames the function to
perf_pmu__convert_scale and changes the function to global.  No
functional change.

38847db974 libtraceevent, perf tools: Changes in tep_print_event_* APIs
Libtraceevent APIs for printing various trace events information are
complicated, there are complex extra parameters. To control the way
event information is printed, the user should call a set of functions in
a specific sequence.

These APIs are reimplemented to provide a more simple interface for
printing event information.

Removed APIs:

 	tep_print_event_task()
	tep_print_event_time()
	tep_print_event_data()
	tep_event_info()
	tep_is_latency_format()
	tep_set_latency_format()
	tep_data_latency_format()
	tep_set_print_raw()

A new API for printing event information is introduced:
   void tep_print_event(struct tep_handle *tep, struct trace_seq *s,
		        struct tep_record *record, const char *fmt, ...);
where "fmt" is a printf-like format string, followed by the event
fields to be printed. Supported fields:
 TEP_PRINT_PID, "%d" - event PID
 TEP_PRINT_CPU, "%d" - event CPU
 TEP_PRINT_COMM, "%s" - event command string
 TEP_PRINT_NAME, "%s" - event name
 TEP_PRINT_LATENCY, "%s" - event latency
 TEP_PRINT_TIME, %d - event time stamp. A divisor and precision
   can be specified as part of this format string:
   "%precision.divisord". Example:
   "%3.1000d" - divide the time by 1000 and print the first 3 digits
   before the dot. Thus, the time stamp "123456000" will be printed as
   "123.456"
 TEP_PRINT_INFO, "%s" - event information.
 TEP_PRINT_INFO_RAW, "%s" - event information, in raw format.

Example:
  tep_print_event(tep, s, record, "%16s-%-5d [%03d] %s %6.1000d %s %s",
		  TEP_PRINT_COMM, TEP_PRINT_PID, TEP_PRINT_CPU,
		  TEP_PRINT_LATENCY, TEP_PRINT_TIME, TEP_PRINT_NAME, TEP_PRINT_INFO);
Output:
	ls-11314 [005] d.h. 185207.366383 function __wake_up

4cb3c6d546 perf event: Remove needless include directives from event.h
bpf.h and build-id.h are not needed at all in event.h, remove them.

And fixup the fallout of files that were getting needed stuff from this
now pruned include.

03e61929c0 arm64: dts: rockchip: limit clock rate of MMC controllers for RK3328
150MHz is a fundamental limitation of RK3328 Soc, w/o this limitation,
eMMC, for instance, will run into 200MHz clock rate in HS200 mode, which
makes the RK3328 boards not always boot properly. By adding it in
rk3328.dtsi would also obviate the worry of missing it when adding new
boards.

8520a98dba perf debug: Remove needless include directives from debug.h
All we need there is a forward declaration for 'union perf_event', so
remove it from there and add missing header directives in places using
things from this indirect include.
