Merge series "opp: Unconditionally call dev_pm_opp_of_remove_table()" from Viresh Kumar <viresh.kumar@linaro.org>:

Hello,

This cleans up some of the user code around calls to
dev_pm_opp_of_remove_table().

All the patches can be picked by respective maintainers directly except
for the last patch, which needs the previous two to get merged first.

These are based for 5.9-rc1.

Rajendra, Since most of these changes are related to qcom stuff, it
would be great if you can give them a try. I wasn't able to test them
due to lack of hardware.

Ulf, I had to revise the sdhci patch, sorry about that. Please pick this
one.

Diff between V1 and V2 is mentioned in each of the patches separately.

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

size 120
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ID|CPU|PERIOD

For Before/After, exclude_guest are both 0 for perf kvm usage.

Merge tag 'perf-tools-2020-08-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:
"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 to 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"

perf tools: Fix term parsing for raw syntax

Jin Yao reported issue with possible conflict between raw events and
term values in pmu event syntax.

Currently following syntax is resolved as raw event with 0xead value:

uncore_imc_free_running/read/

instead of using 'read' term from uncore_imc_free_running pmu, because
'read' is correct raw event syntax with 0xead value.

To solve this issue we do following:

- check existing terms during rXXXX syntax processing
and make them priority in case of conflict

- allow pmu/r0x1234/ syntax to be able to specify conflicting
raw event (implemented in previous patch)

Also add automated tests for this and perf_pmu__parse_cleanup call to
parse_events_terms, so the test gets properly cleaned up.
