Currently aliasing an asm function requires adding START and END
annotations for each name, as per Documentation/asm-annotations.rst:
SYM_FUNC_START_ALIAS(__memset)
SYM_FUNC_START(memset)
... asm insns ...
SYM_FUNC_END(memset)
SYM_FUNC_END_ALIAS(__memset)
This is more painful than necessary to maintain, especially where a
function has many aliases, some of which we may wish to define
conditionally. For example, arm64's memcpy/memmove implementation (which
uses some arch-specific SYM_*() helpers) has:
SYM_FUNC_START_ALIAS(__memmove)
SYM_FUNC_START_ALIAS_WEAK_PI(memmove)
SYM_FUNC_START_ALIAS(__memcpy)
SYM_FUNC_START_WEAK_PI(memcpy)
... asm insns ...
SYM_FUNC_END_PI(memcpy)
EXPORT_SYMBOL(memcpy)
SYM_FUNC_END_ALIAS(__memcpy)
EXPORT_SYMBOL(__memcpy)
SYM_FUNC_END_ALIAS_PI(memmove)
EXPORT_SYMBOL(memmove)
SYM_FUNC_END_ALIAS(__memmove)
EXPORT_SYMBOL(__memmove)
SYM_FUNC_START(name)
It would be much nicer if we could define the aliases *after* the
standard function definition. This would avoid the need to specify each
symbol name twice, and would make it easier to spot the canonical
function definition.
This patch adds new macros to allow us to do so, which allows the above
example to be rewritten more succinctly as:
SYM_FUNC_START(__pi_memcpy)
... asm insns ...
SYM_FUNC_END(__pi_memcpy)
SYM_FUNC_ALIAS(__memcpy, __pi_memcpy)
EXPORT_SYMBOL(__memcpy)
SYM_FUNC_ALIAS_WEAK(memcpy, __memcpy)
EXPORT_SYMBOL(memcpy)
SYM_FUNC_ALIAS(__pi_memmove, __pi_memcpy)
SYM_FUNC_ALIAS(__memmove, __pi_memmove)
EXPORT_SYMBOL(__memmove)
SYM_FUNC_ALIAS_WEAK(memmove, __memmove)
EXPORT_SYMBOL(memmove)
The reduction in duplication will also make it possible to replace some
uses of WEAK with more accurate Kconfig guards, e.g.
#ifndef CONFIG_KASAN
SYM_FUNC_ALIAS(memmove, __memmove)
EXPORT_SYMBOL(memmove)
#endif
... which should make it easier to ensure that symbols are neither used
nor overidden unexpectedly.
The existing SYM_FUNC_START_ALIAS() and SYM_FUNC_START_LOCAL_ALIAS() are
marked as deprecated, and will be removed once existing users are moved
over to the new scheme.
The tools/perf/ copy of linkage.h is updated to match. A subsequent
patch will depend upon this when updating the x86 asm annotations.

The 'perf record' and 'perf stat' commands have supported the option
'-C/--cpus' to count or collect only on the list of CPUs provided.
Commit 1d3351e631fc34d7 ("perf tools: Enable on a list of CPUs for
hybrid") add it to be supported for hybrid. For hybrid support, it
checks the cpu list are available on hybrid PMU. But when we test only
uncore events(or events not in cpu_core and cpu_atom), there is a bug:
Before:
# perf stat -C0 -e uncore_clock/clockticks/ sleep 1
failed to use cpu list 0
In this case, for uncore event, its pmu_name is not cpu_core or
cpu_atom, so in evlist__fix_hybrid_cpus, perf_pmu__find_hybrid_pmu
should return NULL,both events_nr and unmatched_count should be 0 ,then
the cpu list check function evlist__fix_hybrid_cpus return -1 and the
error "failed to use cpu list 0" will happen. Bypass "events_nr=0" case
then the issue is fixed.
After:
# perf stat -C0 -e uncore_clock/clockticks/ sleep 1
Performance counter stats for 'CPU(s) 0':
195,476,873 uncore_clock/clockticks/
1.004518677 seconds time elapsed
When testing with at least one core event and uncore events, it has no
issue.
# perf stat -C0 -e cpu_core/cpu-cycles/,uncore_clock/clockticks/ sleep 1
Performance counter stats for 'CPU(s) 0':
5,993,774 cpu_core/cpu-cycles/
301,025,912 uncore_clock/clockticks/
1.003964934 seconds time elapsed

Skip the Sigtrap test for arm + arm64, same as was done for s390 in
commit a840974e96fd ("perf test: Test 73 Sig_trap fails on s390"). For
this, reuse BP_SIGNAL_IS_SUPPORTED - meaning that the arch can use BP to
generate signals - instead of BP_ACCOUNT_IS_SUPPORTED, which is
appropriate.
As described by Will at [0], in the test we get stuck in a loop of
handling the HW breakpoint exception and never making progress. GDB
handles this by stepping over the faulting instruction, but with perf
the kernel is expected to handle the step (which it doesn't for arm).
Dmitry made an attempt to get this work, also mentioned in the same
thread as [0], which was appreciated. But the best thing to do is skip
the test for now.

'perf inject' with Coresight data generates files that cannot be opened
when only the last branch option is specified:
perf inject -i perf.data --itrace=l -o inject.data
perf script -i inject.data
0x33faa8 [0x8]: failed to process type: 9 [Bad address]
This is because cs_etm__synth_instruction_sample() is called even when
the sample type for instructions hasn't been setup. Last branch records
are attached to instruction samples so it doesn't make sense to generate
them when --itrace=i isn't specified anyway.
This change disables all calls of cs_etm__synth_instruction_sample()
unless --itrace=i is specified, resulting in a file with no samples if
only --itrace=l is provided, rather than a bad file.

The function trace__symbols_init() runs "perf-read-vdso32" and that ends up
with a SIGCHLD delivered to 'perf'. And this SIGCHLD make perf exit early.
'perf trace' should exit only if the SIGCHLD is from our workload process.
So let's use sigaction() instead of signal() to match such condition.
Committer notes:
Use memset to zero the 'struct sigaction' variable as the '= { 0 }'
method isn't accepted in many compiler versions, e.g.:

With the existing symbol_from/symbol_to, branches captured in the same
function would be collapsed into a single function if the latencies
associated with the each branch (cycles) were all the same. That is the
case on Intel Broadwell, for instance. Since Intel Skylake, the latency
is captured by hardware and therefore is used to disambiguate branches.
Add addr_from/addr_to sort dimensions to sort branches based on their
addresses and not the function there are in. The output is still the
function name but the offset within the function is provided to uniquely
identify each branch. These new sort dimensions also help with annotate
because they create different entries in the histogram which, in turn,
generates proper branch annotations.
Here is an example using AMD's branch sampling:
$ perf record -a -b -c 1000037 -e cpu/branch-brs/ test_prg

When testing metric expressions we fake counter values from 1 going
upward. For some metrics this can yield negative values that are clipped
to zero, and then cause divide by zero failures.
Such clipping is questionable but may be a result of tools automatically
generating metrics. A workaround for this case is to try a second time
with counter values going in the opposite direction.
This case was seen in a metric like:
event1 / max(event2 - event3, 0)
But it may also happen in more sensible metrics like:
event1 / (event2 + event3 - 1 - event4)

Some code in builtin-c2c.c calls bitmap_weight() to check if any bit of
a given bitmap is set.
It's better to use bitmap_empty() in that case because bitmap_empty()

Define 2 new flags to represent:
- when interrupts are disabled (D)
- when interrupt disabling toggles (t)
This gives 4 combinations:
no flag, interrupts enabled
t interrupts were enabled but become disabled
D interrupts are disabled
Dt interrupts were disabled but become enabled
Committer notes:
Those are control flow flags, as per 'tools/perf/Documentation/perf-intel-pt.txt:
<quote>
An interesting field that is not printed by default is 'flags' which can be
displayed as follows:
perf script --itrace=ibxwpe -F+flags
The flags are "bcrosyiABExgh" which stand for branch, call, return, conditional,
system, asynchronous, interrupt, transaction abort, trace begin, trace end,
in transaction, VM-entry, and VM-exit respectively.

Previously, the MODE.Exec packet did not generate any events, so the

processing
As of Intel SDM (https://www.intel.com/sdm) version 076, there is a new
Intel PT feature called Event Trace which requires 2 new packets CFE
(Control Flow Event) and EVD (Event Data).
Each Event Trace event is represented by a CFE packet that is preceded
by zero or more EVD packets. It may be bound to a following FUP (Flow
Update) packet that provides the IP.
Event Trace exposes details about asynchronous events. The CFE packet
contains a type field to identify one of the following:
1 INTR interrupt, fault, exception, NMI
2 IRET interrupt return
3 SMI system management interrupt
4 RSM resume from system management mode
5 SIPI startup interprocessor interrupt
6 INIT INIT signal
7 VMENTRY VM-Entry
8 VMEXIT VM-Entry
9 VMEXIT_INTR VM-Exit due to interrupt
10 SHUTDOWN Shutdown
For more details, refer to the Intel SDM, Intel Processor Trace chapter.
Add processing to the decoder for the new packets.

Committer notes:
I got the "Intel® 64 and IA-32 architectures software developer’s manual

https://cdrdv2.intel.com/v1/dl/getContent/671200
And these new packets are described in page 3951:
<quote>
32.2.4
Event Trace is a capability that exposes details about the asynchronous
events, when they are generated, and when their corresponding software
event handler completes execution. These include:
o Interrupts, including NMI and SMI, including the interrupt vector when
defined.
o Faults, exceptions including the fault vector.
— Page faults additionally include the page fault address, when in context.
o Event handler returns, including IRET and RSM.
o VM exits and VM entries.¹
— VM exits include the values written to the “exit reason” and “exit qualification” VMCS fields.
INIT and SIPI events.
o TSX aborts, including the abort status returned for the RTM instructions.
o Shutdown.
Additionally, it provides indication of the status of the Interrupt Flag
(IF), to indicate when interrupts are masked.

$(or ...) is available since GNU Make 3.81, and useful to shorten the
code in some places.
Covert as follows:
$(if A,A,B) --> $(or A,B)
This patch also converts:
$(if A, A, B) --> $(or A, B)
Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".
Anyway, preceding spaces are not significant in the code hunks I touched.
