perf test: Move each test suite struct to its test

perf test: Make each test/suite its own struct.
By switching to an array of pointers to tests (later to be suites) the definition of the tests can be moved to the file containing the tests. Committer notes: It's "&vectors_page", not "&vectors_pages", noticed when cross building to 32-bit ARM. Also the DEFINE_SUITE(vectors_page) should be done where its function is implemented, in tools/perf/arch/arm/tests/vectors-page.c, so that we can make it static, as we don't have anymore its declaration in tests.h.

perf tools: Support pmu prefix for mem-load event
The perf_mem_events__name() can generate the mem-load event name. It uses a variable 'mem_loads_name__init' to avoid generating the event name every time (because perf_pmu__scan takes some time). The perf_mem_events__name() assumes the pmu is "cpu" but it's not correct for hybrid platform. For Alderlake, the pmu is "cpu_core" or "cpu_atom" Introduce a new parameter 'pmu_name' in perf_mem_events__name to let the caller specify a pmu name. Considering such event name is x86 specific, so move perf_mem_events[] to arch/x86/util/mem-events.c. We still keep the variable 'mem_loads_name__init' but it's only used when pmu_name is NULL (compatible for original behavior). When pmu_name is not NULL (e.g. "cpu_core"), this patch doesn't have optimization. That can be implemented in follow up patch.

perf tools: Support pipeline stage cycles for powerpc
The pipeline stage cycles details can be recorded on powerpc from the contents of Performance Monitor Unit (PMU) registers. On ISA v3.1 platform, sampling registers exposes the cycles spent in different pipeline stages. Patch adds perf tools support to present two of the cycle counter information along with memory latency (weight). Re-use the field 'ins_lat' for storing the first pipeline stage cycle. This is stored in 'var2_w' field of 'perf_sample_weight'. Add a new field 'p_stage_cyc' to store the second pipeline stage cycle which is stored in 'var3_w' field of perf_sample_weight. Add new sort function 'Pipeline Stage Cycle' and include this in default_mem_sort_order[]. This new sort function may be used to denote some other pipeline stage in another architecture. So add this to list of sort entries that can have dynamic header string.

perf powerpc: Fix gap between kernel end and module start
Running "perf mem report" in TUI mode fails with ENOMEM message in
powerpc:
failed to process sample
Running with debug and verbose options points that issue is while
allocating memory for sample histograms.
The error path is:
symbol__inc_addr_samples() ->
__symbol__inc_addr_samples() ->
annotated_source__histogram()
symbol__inc_addr_samples() calls annotated_source__alloc_histograms ()
to allocate memory for sample histograms using calloc(). Here calloc()
fails since the size of symbol is huge. The size of a symbol is
calculated as difference between its start and end address.
Example histogram allocation that fails is:
sym->name is _end
sym->start is 0xc0000000027a0000
sym->end is 0xc008000003890000
symbol__size(sym) is 0x80000010f0000
In the above case, the difference between sym->start
(0xc0000000027a0000) and sym->end (0xc008000003890000) is huge.
This is same problem as in s390 and arm64 which are fixed in commits:

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Generally I'm less enthusiastic about "let's use in_compat_syscall() deep in call chain" kind of approach than Christoph seems to be, but in this case it's warranted - that had been an NFS-specific wart, hopefully not to be repeated in any other filesystems (read: any new filesystem introducing non-text mount options will get NAKed even if it doesn't mess the layout up). IOW, not worth trying to grow an infrastructure that would avoid that use of in_compat_syscall()..." * 'compat.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs: remove compat_sys_mount fs,nfs: lift compat nfs4 mount data handling into the nfs code nfs: simplify nfs4_parse_monolithic |

perf tools changes for v5.9
New features:
- Introduce controlling how 'perf stat' and 'perf record' works via a
control file descriptor, allowing starting with events configured but
disabled until commands are received via the control file descriptor.
This allows, for instance for tools such as Intel VTune to make further
use of perf as its Linux platform driver.
- Improve 'perf record' to to register in a perf.data file header the clockid
used to help later correlate things like syslog files and perf events
recorded.
- Add basic syscall and find_next_bit benchmarks to 'perf bench'.
- Allow using computed metrics in calculating other metrics. For instance:
{
.metric_expr = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit",
.metric_name = "DCache_L2_All_Hits",
},
{
.metric_expr = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss",
.metric_name = "DCache_L2_All_Miss",
},
{
.metric_expr = "dcache_l2_all_hits + dcache_l2_all_miss",
.metric_name = "DCache_L2_All",
}
- Add suport for 'd_ratio', '>' and '<' operators to the expression resolver used
in calculating metrics in 'perf stat'.
Support for new kernel features:
- Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope with
things like ftrace, trampolines, i.e. changes in the kernel text that gets
in the way of properly decoding Intel PT hardware traces, for instance.
Intel PT:
- Add various knobs to reduce the volume of Intel PT traces by reducing the
level of details such as decoding just some types of packets (e.g., FUP/TIP,
PSB+), also filtering by time range.
- Add new itrace options (log flags to the 'd' option, error flags to the 'e'
one, etc), controlling how Intel PT is transformed into perf events, document
some missing options (e.g., how to synthesize callchains).
BPF:
- Properly report BPF errors when parsing events.
- Do not setup side-band events if LIBBPF is not linked, fixing a segfault.
Libraries:
- Improvements on the libtraceevent plugin mechanism.
- Improve libtracevent support for KVM trace events SVM exit reasons.
- Add a libtracevent plugins for decoding syscalls/sys_enter_futex and for tlb_flush.
- Ensure sample_period is set libpfm4 events in 'perf test'.
- Fixup libperf namespacing, to make sure what is in libperf has the perf_
namespace while what is now only in tools/perf/ doesn't use that prefix.
Arch specific:
- Improve the testing of vendor events and metrics in 'perf test'.
- Allow no ARM CoreSight hardware tracer sink to be specified on command line.
- Fix arm_spe_x recording when mixed with other perf events.
- Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of idle symbols.
- List kernel supplied event aliases for arm64 in 'perf list'.
- Add support for extended register capability in PowerPC 9 and 10.
- Added nest IMC power9 metric events.
Miscellaneous:
- No need to setup sample_regs_intr/sample_regs_user for dummy events.
- Update various copies of kernel headers, some causing perf to handle new
syscalls, MSRs, etc.
- Improve usage of flex and yacc, enabling warnings and addressing the fallout.
- Add missing '--output' option to 'perf kmem' so that it can pass it along to 'perf record'.
- 'perf probe' fixes related to adding multiple probes on the same address for
the same event.
- Make 'perf probe' warn if the target function is a GNU indirect function.
- Remove //anon mmap events from 'perf inject jit' to fix supporting both using
ELF files for generated functions and the perf-PID.map approaches.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
works), fixes will be provided soon.
clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.
The ones failing when linking with libllvm, not the default build, were
restricted to clang-9/llvm-9, working with anything before or after, e.g.,
using clang-8 on ubuntu:19.10 and clang-11 on debian:experimental fixed the
build in those environments.

powerpc updates for 5.9
- Add support for (optionally) using queued spinlocks & rwlocks.
- Support for a new faster system call ABI using the scv instruction on Power9
or later.
- Drop support for the PROT_SAO mmap/mprotect flag as it will be unsupported on
Power10 and future processors, leaving us with no way to implement the
functionality it requests. This risks breaking userspace, though we believe
it is unused in practice.
- A bug fix for, and then the removal of, our custom stack expansion checking.
We now allow stack expansion up to the rlimit, like other architectures.
- Remove the remnants of our (previously disabled) topology update code, which
tried to react to NUMA layout changes on virtualised systems, but was prone
to crashes and other problems.
- Add PMU support for Power10 CPUs.
- A change to our signal trampoline so that we don't unbalance the link stack
(branch return predictor) in the signal delivery path.
- Lots of other cleanups, refactorings, smaller features and so on as usual.

perf tools powerpc: Add support for extended register capability
Add extended regs to sample_reg_mask in the tool side to use with `-I?` option. Perf tools side uses extended mask to display the platform supported register names (with -I? option) to the user and also send this mask to the kernel to capture the extended registers in each sample. Hence decide the mask value based on the processor version. Currently definitions for `mfspr`, `SPRN_PVR` are part of `arch/powerpc/util/header.c`. Move this to a header file so that these definitions can be re-used in other source files as well.

KVM: PPC: Fix typo on H_DISABLE_AND_GET hcall
On PAPR+ the hcall() on 0x1B0 is called H_DISABLE_AND_GET, but got
defined as H_DISABLE_AND_GETC instead.
This define was introduced with a typo in commit <b13a96cfb055>
("[PATCH] powerpc: Extends HCALL interface for InfiniBand usage"), and was
later used without having the typo noticed.

net: remove compat_sys_{get,set}sockopt
Now that the ->compat_{get,set}sockopt proto_ops methods are gone
there is no good reason left to keep the compat syscalls separate.
This fixes the odd use of unsigned int for the compat_setsockopt
optlen and the missing sock_use_custom_sol_socket.
It would also easily allow running the eBPF hooks for the compat
syscalls, but such a large change in behavior does not belong into
a consolidation patch like this one.

perf metricgroups: Enhance JSON/metric infrastructure to handle "?"
Patch enhances current metric infrastructure to handle "?" in the metric
expression. The "?" can be use for parameters whose value not known
while creating metric events and which can be replace later at runtime
to the proper value. It also add flexibility to create multiple events
out of single metric event added in JSON file.
Patch adds function 'arch_get_runtimeparam' which is a arch specific
function, returns the count of metric events need to be created. By
default it return 1.
This infrastructure needed for hv_24x7 socket/chip level events.
"hv_24x7" chip level events needs specific chip-id to which the data is
requested. Function 'arch_get_runtimeparam' implemented in header.c
which extract number of sockets from sysfs file "sockets" under
"/sys/devices/hv_24x7/interface/".
With this patch basically we are trying to create as many metric events
as define by runtime_param.
For that one loop is added in function 'metricgroup__add_metric', which
create multiple events at run time depend on return value of
'arch_get_runtimeparam' and merge that event in 'group_list'.
To achieve that we are actually passing this parameter value as part of
`expr__find_other` function and changing "?" present in metric
expression with this value.
As in our JSON file, there gonna be single metric event, and out of
which we are creating multiple events.
To understand which data count belongs to which parameter value,
we also printing param value in generic_metric function.
For example,
command:# ./perf stat -M PowerBUS_Frequency -C 0 -I 1000
1.000101867 9,356,933 hv_24x7/pm_pb_cyc,chip=0/ # 2.3 GHz PowerBUS_Frequency_0
1.000101867 9,366,134 hv_24x7/pm_pb_cyc,chip=1/ # 2.3 GHz PowerBUS_Frequency_1
2.000314878 9,365,868 hv_24x7/pm_pb_cyc,chip=0/ # 2.3 GHz PowerBUS_Frequency_0
2.000314878 9,366,092 hv_24x7/pm_pb_cyc,chip=1/ # 2.3 GHz PowerBUS_Frequency_1
So, here _0 and _1 after PowerBUS_Frequency specify parameter value.

perf symbols: Consolidate symbol fixup issue
After copying Arm64's perf archive with object files and perf.data file to x86 laptop, the x86's perf kernel symbol resolution fails. It outputs 'unknown' for all symbols parsing. This issue is root caused by the function elf__needs_adjust_symbols(), x86 perf tool uses one weak version, Arm64 (and powerpc) has rewritten their own version. elf__needs_adjust_symbols() decides if need to parse symbols with the relative offset address; but x86 building uses the weak function which misses to check for the elf type 'ET_DYN', so that it cannot parse symbols in Arm DSOs due to the wrong result from elf__needs_adjust_symbols(). The DSO parsing should not depend on any specific architecture perf building; e.g. x86 perf tool can parse Arm and Arm64 DSOs, vice versa. And confirmed by Naveen N. Rao that powerpc64 kernels are not being built as ET_DYN anymore and change to ET_EXEC. This patch removes the arch specific functions for Arm64 and powerpc and changes elf__needs_adjust_symbols() as a common function. In the common elf__needs_adjust_symbols(), it checks an extra condition 'ET_DYN' for elf header type. With this fixing, the Arm64 DSO can be parsed properly with x86's perf tool.
