perf tools: Add build test with GTK+
So that when we use: make -C tools/perf build-test One of the entries will ask for building with GTK+ 2.

tools feature: Add missing -lzstd to the fast path feature detection
We were failing that due to GTK2+ and then for the ZSTD test, which made
test-all.c, the fast path feature detection file to fail and thus
trigger building all of the feature tests, slowing down the test.
Eventually the ZSTD test would be built and would succeed, since it had
the needed -lzstd, avoiding:
$ cat /tmp/build/perf/feature/test-all.make.output
/usr/bin/ld: /tmp/ccRRJQ4u.o: in function `main_test_libzstd':
/home/acme/git/perf/tools/build/feature/test-libzstd.c:8: undefined reference to `ZSTD_createCStream'
/usr/bin/ld: /home/acme/git/perf/tools/build/feature/test-libzstd.c:9: undefined reference to `ZSTD_freeCStream'
collect2: error: ld returned 1 exit status
$
Fix it by adding -lzstd to the test-all target.
Now I need an entry to 'perf test' to make sure that
/tmp/build/perf/feature/test-all.make.output is empty...

perf tools: Make GTK2 support opt-in
This is bitrotting, nobody is stepping up to work on it, and since we treat warnings as errors, feature detection is failing in its main, faster test (tools/build/feature/test-all.c) because of the GTK+2 infobar check. So make this opt-in, at some point ditch this if nobody volunteers to take care of this.

perf vendor events amd: Add recommended events
Add support for events listed in Section 2.1.15.2 "Performance
Measurement" of "PPR for AMD Family 17h Model 31h B0 - 55803
Rev 0.54 - Sep 12, 2019".
perf now supports these new events (-e):
all_dc_accesses
all_tlbs_flushed
l1_dtlb_misses
l2_cache_accesses_from_dc_misses
l2_cache_accesses_from_ic_misses
l2_cache_hits_from_dc_misses
l2_cache_hits_from_ic_misses
l2_cache_misses_from_dc_misses
l2_cache_misses_from_ic_miss
l2_dtlb_misses
l2_itlb_misses
sse_avx_stalls
uops_dispatched
uops_retired
l3_accesses
l3_misses
and these metrics (-M):
branch_misprediction_ratio
all_l2_cache_accesses
all_l2_cache_hits
all_l2_cache_misses
ic_fetch_miss_ratio
l2_cache_accesses_from_l2_hwpf
l2_cache_hits_from_l2_hwpf
l2_cache_misses_from_l2_hwpf
l3_read_miss_latency
l1_itlb_misses
all_remote_links_outbound
nps1_die_to_dram
The nps1_die_to_dram event may need perf stat's --metric-no-group
switch if the number of available data fabric counters is less
than the number it uses (8).

perf vendor events amd: Add ITLB Instruction Fetch Hits event for zen1
The ITLB Instruction Fetch Hits event isn't documented even in later
zen1 PPRs, but it seems to count correctly on zen1 hardware.
Add it to zen1 group so zen1 users can use the upcoming IC Fetch Miss
Ratio Metric.
The IF1G, 1IF2M, IF4K (Instruction fetches to a 1 GB, 2 MB, and 4K page)
unit masks are not added because unlike zen2 hardware, zen1 hardware
counts all its unit masks with a 0 unit mask according to the old
convention:
zen1$ perf stat -e cpu/event=0x94/,cpu/event=0x94,umask=0xff/ sleep 1
Performance counter stats for 'sleep 1':
211,318 cpu/event=0x94/u
211,318 cpu/event=0x94,umask=0xff/u
Rome/zen2:
zen2$ perf stat -e cpu/event=0x94/,cpu/event=0x94,umask=0xff/ sleep 1
Performance counter stats for 'sleep 1':
0 cpu/event=0x94/u

perf vendor events amd: Add L2 Prefetch events for zen1
Later revisions of PPRs that post-date the original Family 17h events
submission patch add these events.
Specifically, they were not in this 2017 revision of the F17h PPR:
Processor Programming Reference (PPR) for AMD Family 17h Model 01h, Revision B1 Processors Rev 1.14 - April 15, 2017
But e.g., are included in this 2019 version of the PPR:

perf tests: Add test for PE binary format support
This adds a precompiled file in PE binary format, with split debug file, and tries to read its build_id and .gnu_debuglink sections, as well as looking up the main symbol from the debug file.

perf symbols: Try reading the symbol table with libbfd
Wine generates PE binaries for its code modules and also generates debug
files in PE or PDB formats, which perf cannot parse either.
Trying to read symbols on non-ELF binaries with libbfd, when supported,
makes it possible for perf to report symbols and annotations for Windows
applications running under Wine.
Because libbfd doesn't provide symbol size (probably because of some
backends not supporting it), we compute it by first sorting the symbols
by addresses and then considering that they are sequential in a given
section.
v3: Also include local and weak bfd symbols and mark them as such, only
global symbols were previously reported, and that caused a very
imprecise address to symbol resolution.

perf dso: Use libbfd to read build_id and .gnu_debuglink section
Wine generates PE binaries for most of its modules and perf is unable to parse these files to get build_id or .gnu_debuglink section. Using libbfd when available, instead of libelf, makes it possible to resolve debug file location regardless of the dso binary format. Committer notes: Made the filename__read_build_id() variant that uses abfd->build_id depend on the feature test that defines HAVE_LIBBFD_BUILDID_SUPPORT, to get this to continue building with older libbfd/binutils.

perf tools fixes for v5.9: 2nd batch
- Use uintptr_t when casting numbers to pointers
- Keep output expected by 3rd parties: Turn off summary for interval
mode by default.
- BPF is in kernel space, make sure do_validate_kcore_modules() knows
about that.
- Explicitly call out event modifiers in the documentation.
- Fix jevents() allocation of space for regular expressions.
- Address libtraceevent build warnings on 32-bit arches.
- Fix checking of functions returns using ERR_PTR() in 'perf bench'.

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.

selftests/x86/test_vsyscall: Improve the process_vm_readv() test
The existing code accepted process_vm_readv() success or failure as long as it didn't return garbage. This is too weak: if the vsyscall page is readable, then process_vm_readv() should succeed and, if the page is not readable, then it should fail.

perf tools: Add bpf image check to __map__is_kmodule
When validating kcore modules the do_validate_kcore_modules function
checks on every kernel module dso against modules record. The
__map__is_kmodule check is used to get only kernel module dso objects
through.
Currently the bpf images are slipping through the check and making the
validation to fail, so report falls back from kcore usage to kallsyms.
Adding __map__is_bpf_image check for bpf image and adding it to
__map__is_kmodule check.

perf bench: The do_run_multi_threaded() function must use IS_ERR(perf_session__new())
In case of error, the function perf_session__new() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR()
Committer notes:
This wasn't compiling due to an extraneous '{' not matched by a '}', fix
it.

perf stat: Turn off summary for interval mode by default
There's a risk that outputting interval mode summaries by default breaks
CSV consumers. It already broke pmu-tools/toplev.
So now we turn off the summary by default but we create a new option
'--summary' to enable the summary. This is active even when not using
CSV mode.

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.

perf tools: Correct SNOOPX field offset
perf_event.h has macros that define the field offsets in the data_src
bitmask in perf records. The SNOOPX and REMOTE offsets were both 37.
These are distinct fields, and the bitfield layout in perf_mem_data_src
confirms that SNOOPX should be at offset 38.

This was extracted from a larger patch that also contained kernel

perf top/report: Fix infinite loop in the TUI for grouped events
For a while we need to have a dummy event for doing things like
receiving PERF_RECORD_COMM, PERF_RECORD_EXEC, etc for threads being
created and dying while we synthesize the pre-existing ones at tool
start.
This 'dummy' event is needed for keeping track of thread lifetime events
early in the session but are uninteresting otherwise, i.e. no need to
have it in a initial events menu for the non-grouped case, i.e. for:
# perf top -e cycles,instructions
or even for plain:
# perf top
When 'cycles' and that 'dummy' event are in place.
The code to remove that 'dummy' event ended up creating an endless loop
for the grouped case, i.e.:
# perf top -e '{cycles,instructions}'
Fix it.

perf stat: Fix out of bounds array access in the print_counters() evlist method
Fix a compile error on F32 and gcc version 10.1 on s390 in file
utils/stat-display.c. The error does not show up with make DEBUG=y. In
fact the issue shows up when using both compiler options -O6 and
-D_FORTIFY_SOURCE=2 (which are omitted with DEBUG=Y).
This is the offending call chain:
print_counter_aggr()
printout(config, -1, 0, ...) with 2nd parm id set to -1
aggr_printout(config, x, id --> -1, ...) which leads to this code:
case AGGR_NONE:
if (evsel->percore && !config->percore_show_thread) {
....
} else {
fprintf(config->output, "CPU%*d%s",
config->csv_output ? 0 : -7,
evsel__cpus(evsel)->map[id],
^^ id is -1 !!!!
config->csv_sep);
}
This is a compiler inlining issue which is detected on s390 but not on
other plattforms.
Output before:
# make util/stat-display.o

perf parse-events: Set exclude_guest=1 for user-space counting
Currently if we run 'perf record -e cycles:u', exclude_guest=0.
But it doesn't make sense in most cases that we request for
user-space counting but we also get the guest report.
Of course, we also need to consider 'perf kvm' usage case that
authorized perf users on the host may only want to count guest user
space events. For example,
# perf kvm --guest record -e cycles:u
When we have 'exclude_guest=1' for 'perf kvm' usage, we may get nothing
from guest events.
To keep perf semantics consistent and clear, this patch sets
exclude_guest=1 for user-space counting but except for 'perf kvm' usage.
Before:
perf record -e cycles:u ./div
perf evlist -v
cycles:u: ..., exclude_kernel: 1, exclude_hv: 1, ...
After:
perf record -e cycles:u ./div
perf evlist -v
cycles:u: ..., exclude_kernel: 1, exclude_hv: 1, exclude_guest: 1, ...
Before:
perf kvm --guest record -e cycles:u -vvv
perf_event_attr:
size 120
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ID|CPU|PERIOD
read_format ID
disabled 1
inherit 1
exclude_kernel 1
exclude_hv 1
freq 1
sample_id_all 1
After:
perf kvm --guest record -e cycles:u -vvv
perf_event_attr:
size 120
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ID|CPU|PERIOD
read_format ID
disabled 1
inherit 1
exclude_kernel 1
exclude_hv 1
freq 1
sample_id_all 1
For Before/After, exclude_guest are both 0 for perf kvm usage.

powerpc fixes for 5.9 #4
Revert our removal of PROT_SAO, at least one user expressed an interest in using it on Power9. Instead don't allow it to be used in guests unless enabled explicitly at compile time. A fix for a crash introduced by a recent change to FP handling. Revert a change to our idle code that left Power10 with no idle support. One minor fix for the new scv system call path to set PPR. Fix a crash in our "generic" PMU if branch stack events were enabled. A fix for the IMC PMU, to correctly identify host kernel samples. The ADB_PMU powermac code was found to be incompatible with VMAP_STACK, so make them incompatible in Kconfig until the code can be fixed. A build fix in drivers/video/fbdev/controlfb.c, and a documentation fix.

USB fixes for 5.9-rc3 - take 2
Let's try this again... Here are some USB fixes for 5.9-rc3. This differs from the previous pull request for this release in that: - the usb gadget patch now does not break some systems, and actually does what it was intended to do. Many thanks to Marek Szyprowski for quickly noticing and testing the patch from Andy Shevchenko to resolve this issue. - some more new USB quirks have been added to get some new devices to work properly based on user reports. Other than that, the original pull request patches are all here, and they contain: - usb gadget driver fixes - xhci driver fixes - typec fixes - new quirks and ids - fixes for USB patches that went into 5.9-rc1. All of these have been tested in linux-next with no reported issues.
