Move pmu_metrics_table__find() to the jevents.py generated pmu-events.c
and remove indirection override for ARM.
The movement removes perf_pmu__find_metrics_table that exists to enable
the ARM override.
The ARM override isn't necessary as just the CPUID, not PMU, is used in
the metric table lookup.
On non-ARM the CPU argument is just ignored for the CPUID, for ARM -1 is
passed so that the CPUID for the first logical CPU is read.

On ARM the cpuid is dependent on the core type of the CPU in
question. The PMU was passed for the sake of the CPU map but this
means in places a temporary PMU is created just to pass a CPU
value. Just pass the CPU and fix up the callers.
As there are no longer PMU users in header.h, shuffle forward
declarations earlier to work around build failures.

ARM BIG.little has no notion of a constant CPUID for both core
types. To reflect this reality, change the get_cpuid function to also
pass in a possibly unused logical cpu.
If the dummy value (-1) is passed in then ARM can, as currently happens,
select the first logical CPU's "CPUID".
The changes to ARM getcpuid happen in a follow up change.

PERF_HAVE_DWARF_REGS was true when an architecture had a dwarf-regs.c
file. There are no more architecture dwarf-regs.c files, selection is
done using constants from the ELF file rather than conditional
compilation. When removing PERF_HAVE_DWARF_REGS was the only variable
in the Makefile, remove the Makefile.
Add missing SPDX for RISC-V Makefile.

support which was removed in Commit 3d6dfae889 ("perf parse-events:
Remove BPF event support"). The code is no longer used so remove.
Remove the offset from various dwarf-regs.c tables and the dependence
on ptrace.h. Rename structs starting pt_ as the ptrace derived offset is
now removed.

perf list picks the events supported for specific platform
from pmu-events/arch/powerpc/<platform>. Example power10 events
are in pmu-events/arch/powerpc/power10, power9 events are part
of pmu-events/arch/powerpc/power9. The decision of which
platform to pick is determined based on PVR value in powerpc.
The PVR value is matched from pmu-events/arch/powerpc/mapfile.csv
Example:
Format:
PVR,Version,JSON/file/pathname,Type
0x004[bcd][[:xdigit:]]{4},1,power8,core
0x0066[[:xdigit:]]{4},1,power8,core
0x004e[[:xdigit:]]{4},1,power9,core
0x0080[[:xdigit:]]{4},1,power10,core
0x0082[[:xdigit:]]{4},1,power10,core
The code gets the PVR from system using get_cpuid_str function
in arch/powerpc/util/headers.c ( from SPRN_PVR ) and compares
with value from mapfile.csv
In case of compat mode, say when partition is booted in a power9
mode when the system is a power10, this picks incorrectly. Because
PVR will point to power10 where as it should pick events from power9
folder. To support generic events, add new folder
pmu-events/arch/powerpc/compat to contain the ISA architected events
which is supported in compat mode. Also return 0x00ffffff as pvr
when booted in compat mode. Based on this pvr value, json will
pick events from pmu-events/arch/powerpc/compat

Leverage the existed function perf_pmu__name_from_config() to check if
an event is topdown metrics event. perf_pmu__name_from_config() goes
through the defined formats and figures out the config of pre-defined

This avoids to figure out the config of topdown pre-defined events with

metrics events which are not in same group with previous event. But it
just modifies the 2nd comparator and causes the comparators become
asymmetric.
Thus modify the 1st topdown metrics comparator and make the two
comparators be symmetric, and refine the comments as well.

Hard coded terms like "config=10" are skipped by perf_pmu__config
assuming they were already applied to a perf_event_attr by parse
event's config_attr function. When doing a reverse number to name
lookup in perf_pmu__name_from_config, as the hardcoded terms aren't

Error:
The sys_perf_event_open() syscall returned with 22 (Invalid argument) for
event (topdown-retiring).
The reason of error is that the events are regrouped and
topdown-retiring event is moved to closely after the slots event and
topdown-retiring event needs to do the sampling, but Intel PMU driver
doesn't support to sample topdown metrics events.
For topdown metrics events, it just requires to be in a group which has
slots event as leader. It doesn't require topdown metrics event must be
closely after slots event. Thus it's a overkill to move topdown metrics
event closely after slots event in events regrouping and furtherly cause
the above issue.
Thus don't move topdown metrics events forward if they are already in a
group.

Addresses an issue where, in the absence of a topdown metrics event
within a sampling group, the slots event was incorrectly bypassed as
the sampling leader when sample_read was enabled.
perf record -e '{slots,branches}:S' -c 10000 -vv sleep 1
In this case, the slots event should be sampled as leader but the
branches event is sampled in fact like the verbose output shows.

The sample period of slots event instead of branches event is reset to

It's not complete to check whether an event is a topdown slots or
topdown metrics event by only comparing the event name since user
may assign the event by RAW format, e.g.
perf stat -e '{instructions,cpu/r400/,cpu/r8300/}' sleep 1
Performance counter stats for 'sleep 1':
<not counted> instructions
<not counted> cpu/r400/
<not supported> cpu/r8300/
1.002917796 seconds time elapsed
0.002955000 seconds user
0.000000000 seconds sys
The RAW format slots and topdown-be-bound events are not recognized and
not regroup the events, and eventually cause error.
Thus add two helpers arch_is_topdown_slots()/arch_is_topdown_metrics()
to detect whether an event is topdown slots/metrics event by comparing
the event config directly, and use these two helpers to replace the
original event name comparisons.

add_default_atttributes would add evsels by having pre-created
perf_event_attr, however, this needed fixing for hybrid as the
extended PMU type was necessary for each core PMU. The logic for this
was in an arch specific x86 function and wasn't present for ARM,
meaning that default events weren't being opened on all PMUs on
ARM. Change the creation of the default events to use parse_events and
strings as that will open the events on all PMUs.
Rather than try to detect events on PMUs before parsing, parse the
event but skip its output in stat-display.
The previous order of hardware events was: cycles,
stalled-cycles-frontend, stalled-cycles-backend, instructions. As
instructions is a more fundamental concept the order is changed to:
instructions, cycles, stalled-cycles-frontend, stalled-cycles-backend.

Now that each queue has a unique set of trace ID mappings, use this
list to create the decoders. In unformatted mode just add a single
mapping so only one decoder is made.
Previously each queue would have a decoder created for each traced CPU
on the system but this won't work anymore because CPUs can have
overlapping trace IDs.
This also means that the CORESIGHT_TRACE_ID_UNUSED_FLAG isn't needed
any more. If mappings aren't added then decoders aren't created, rather
than needing a flag to suppress creation.

In some cases, compilers don't set the location expression in DWARF
precisely. For instance, it may assign a variable to a register after
copying it from a different register. Then it should use the register
for the new type but still uses the old register. This makes hard to
track the type information properly.
This is an example I found in __tcp_transmit_skb(). The first argument
(sk) of this function is a pointer to sock and there's a variable (tp)
for tcp_sock.
static int __tcp_transmit_skb(struct sock *sk, struct sk_buff *skb,
int clone_it, gfp_t gfp_mask, u32 rcv_nxt)
{
...
struct tcp_sock *tp;
BUG_ON(!skb || !tcp_skb_pcount(skb));
tp = tcp_sk(sk);
prior_wstamp = tp->tcp_wstamp_ns;
tp->tcp_wstamp_ns = max(tp->tcp_wstamp_ns, tp->tcp_clock_cache);
...
So it basically calls tcp_sk(sk) to get the tcp_sock pointer from sk.
But it turned out to be the same value because tcp_sock embeds sock as
the first member. The sk is located in reg5 (RDI) and tp is in reg3
(RBX). The offset of tcp_wstamp_ns is 0x748 and tcp_clock_cache is
0x750. So you need to use RBX (reg3) to access the fields in the
tcp_sock. But the code used RDI (reg5) as it has the same value.
$ pahole --hex -C tcp_sock vmlinux | grep -e 748 -e 750
u64 tcp_wstamp_ns; /* 0x748 0x8 */
u64 tcp_clock_cache; /* 0x750 0x8 */
And this is the disassembly of the part of the function.
<__tcp_transmit_skb>:
...
44: mov %rdi, %rbx
47: mov 0x748(%rdi), %rsi
4e: mov 0x750(%rdi), %rax
55: cmp %rax, %rsi
Because compiler put the debug info to RBX, it only knows RDI is a
pointer to sock and accessing those two fields resulted in error
due to offset being beyond the type size.

While it's a fault in the compiler, we could work around this issue by
using the type of new variable when it's copied directly. So I've added
copied_from field in the register state to track those direct register
to register copies. After that new register gets a new type and the old
register still has the same type, it'll update (copy it back) the type
of the old register.
For example, if we can update type of reg5 at __tcp_transmit_skb+0x47,
we can find the target type of the instruction at 0x63 like below:
-----------------------------------------------------------

In check_matching_type(), it checks the type state of the register in a
wrong order. When it's the percpu pointer, it should check the type for
the pointer, but it checks the CFA bit first and thought it has no type
in the stack slot. This resulted in no type info.

I found it missed to copy the immediate constant when it moves the
register value. This could result in a wrong type inference since the
address for the per-cpu variable would be 0 always.
