perf build: Remove PERF_HAVE_DWARF_REGS
...
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.

Update #ifdefs to allow ABI V1 and V2 tables at the same
time. Determine the table from the ELF flags.

The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case
the function can never be called. So remove as dead code. Tidy up the
EM_NONE cases for arm in dwarf-regs.c.

perf dwarf-regs: Add EM_HOST and EF_HOST defines
...
Computed from the build architecture defines, EM_HOST and EF_HOST give
values that can be used in dwarf register lookup. Place in
dwarf-regs.h so the value can be shared. Move some dwarf-regs.c
constants used for EM_HOST to dwarf-regs.h. Add CSky constants that
may be missing.
In disasm.c add an include of dwarf-regs.h as the included
arch/*/annotate/instructions.c files make use of the constants and we
want the elf.h/dwarf-regs.h dependency to be explicit.

perf test: Add hwmon "PMU" test
...
Based on a mix of the sysfs PMU test (for creating the reference
files) and the tool PMU test, test that parsing given hwmon events
with there aliases creates the expected config values.

perf hwmon_pmu: Add a tool PMU exposing events from hwmon in sysfs
...
Add a tool PMU for hwmon events but don't enable.
The hwmon sysfs ABI is defined in
Documentation/hwmon/sysfs-interface.rst. Create a PMU that reads the
hwmon input and can be used in `perf stat` and metrics much as an
uncore PMU can.
For example, when enabled by a later patch, the following shows
reading the CPU temperature and 2 fan speeds alongside the uncore
frequency:
```
$ perf stat -e temp_cpu,fan1,hwmon_thinkpad/fan2/,tool/num_cpus_online/ -M UNCORE_FREQ -I 1000
1.001153138 52.00 'C temp_cpu
1.001153138 2,588 rpm fan1
1.001153138 2,482 rpm hwmon_thinkpad/fan2/
1.001153138 8 tool/num_cpus_online/
1.001153138 1,077,101,397 UNC_CLOCK.SOCKET # 1.08 UNCORE_FREQ
1.001153138 1,012,773,595 duration_time
...
```
The PMUs are named from /sys/class/hwmon/hwmon<num>/name and have an
alias of hwmon<num>.
Hwmon data is presented in multiple <type><number>_<item> files. The
<type><number> is used to identify the event as is the <type> followed
by the contents of the <type>_label file if it exists. The
<type><number>_input file gives the data read by perf.
When enabled by a later patch, in `perf list` the other hwmon <item>
files are used to give a richer description, for example:
```
hwmon:
temp1
[Temperature in unit acpitz named temp1. Unit: hwmon_acpitz]
in0
[Voltage in unit bat0 named in0. Unit: hwmon_bat0]
temp_core_0 OR temp2

temp_core_1 OR temp3
[Temperature in unit coretemp named Core 1. crit=100'C,max=100'C crit_alarm=0'C. Unit:
hwmon_coretemp]
...
temp_package_id_0 OR temp1
[Temperature in unit coretemp named Package id 0. crit=100'C,max=100'C crit_alarm=0'C.
Unit: hwmon_coretemp]
temp1
[Temperature in unit iwlwifi_1 named temp1. Unit: hwmon_iwlwifi_1]
temp_composite OR temp1
[Temperature in unit nvme named Composite. alarm=0'C,crit=86.85'C,max=75.85'C,
min=-273.15'C. Unit: hwmon_nvme]
temp_sensor_1 OR temp2
[Temperature in unit nvme named Sensor 1. max=65261.8'C,min=-273.15'C. Unit: hwmon_nvme]
temp_sensor_2 OR temp3
[Temperature in unit nvme named Sensor 2. max=65261.8'C,min=-273.15'C. Unit: hwmon_nvme]
fan1
[Fan in unit thinkpad named fan1. Unit: hwmon_thinkpad]
fan2
[Fan in unit thinkpad named fan2. Unit: hwmon_thinkpad]
...
temp_cpu OR temp1
[Temperature in unit thinkpad named CPU. Unit: hwmon_thinkpad]
temp_gpu OR temp2
[Temperature in unit thinkpad named GPU. Unit: hwmon_thinkpad]
curr1
[Current in unit ucsi_source_psy_usbc000_0 named curr1. max=1.5A. Unit:
hwmon_ucsi_source_psy_usbc000_0]
in0
[Voltage in unit ucsi_source_psy_usbc000_0 named in0. max=5V,min=5V. Unit:
hwmon_ucsi_source_psy_usbc000_0]
```
As there may be multiple hwmon devices a range of PMU types are
reserved for their use and to identify the PMU as belonging to the
hwmon types.

perf test: Fix ftrace test with regex patterns

During the parallel testing, I've noticed some ftrace test failures. It
seems the regex pattern checks 100 msec of nanosleep with the error
range of 10 msec. But sometimes it's affected by other processes and
resulted in more time in the syscall.
The following output shows that it took more than 120 msec and failed.
Let's update the regex pattern so that it can allow more drifts.

Having multiple unwinding libraries makes the perf code harder to

Perf made BPF support an opt-out rather than opt-in feature. As libbpf
has a libelf dependency, elfutils that provides libelf will also
provide libdw. When libdw is present perf will use libdw unwinding
rather than libunwind unwinding even if libunwind support is compiled
in.
Rather than have libunwind built into perf and never used, explicitly
disable the support and make it opt-in.

mm: multi-gen LRU: use {ptep,pmdp}_clear_young_notify()
...
When the MM_WALK capability is enabled, memory that is mostly accessed by
a VM appears younger than it really is, therefore this memory will be less
likely to be evicted. Therefore, the presence of a running VM can
significantly increase swap-outs for non-VM memory, regressing the
performance for the rest of the system.
Fix this regression by always calling {ptep,pmdp}_clear_young_notify()
whenever we clear the young bits on PMDs/PTEs.

mm: multi-gen LRU: remove MM_LEAF_OLD and MM_NONLEAF_TOTAL stats
...
Patch series "mm: multi-gen LRU: Have secondary MMUs participate in
MM_WALK".
Today, the MM_WALK capability causes MGLRU to clear the young bit from
PMDs and PTEs during the page table walk before eviction, but MGLRU does
not call the clear_young() MMU notifier in this case. By not calling this
notifier, the MM walk takes less time/CPU, but it causes pages that are
accessed mostly through KVM / secondary MMUs to appear younger than they
should be.
We do call the clear_young() notifier today, but only when attempting to
evict the page, so we end up clearing young/accessed information less
frequently for secondary MMUs than for mm PTEs, and therefore they appear
younger and are less likely to be evicted. Therefore, memory that is
*not* being accessed mostly by KVM will be evicted *more* frequently,
worsening performance.
ChromeOS observed a tab-open latency regression when enabling MGLRU with a
setup that involved running a VM:
Tab-open latency histogram (ms)
Version p50 mean p95 p99 max
base 1315 1198 2347 3454 10319
mglru 2559 1311 7399 12060 43758
fix 1119 926 2470 4211 6947
This series replaces the final non-selftest patchs from this series[1],
which introduced a similar change (and a new MMU notifier) with KVM
optimizations. I'll send a separate series (to Sean and Paolo) for the
KVM optimizations.
This series also makes proactive reclaim with MGLRU possible for KVM
memory. I have verified that this functions correctly with the selftest
from [1], but given that that test is a KVM selftest, I'll send it with
the rest of the KVM optimizations later. Andrew, let me know if you'd
like to take the test now anyway.
[1]: https://lore.kernel.org/linux-mm/20240926013506.860253-18-jthoughton@google.com/
This patch (of 2):
The removed stats, MM_LEAF_OLD and MM_NONLEAF_TOTAL, are not very helpful
and become more complicated to properly compute when adding
test/clear_young() notifiers in MGLRU's mm walk.
