- Add AMD Fam17h RAPL support
- Introduce CAP_PERFMON to kernel and user space
- Add Zhaoxin CPU support
- Misc fixes and cleanups
Tooling changes:
perf record:
- Introduce --switch-output-event to use arbitrary events to be setup
and read from a side band thread and, when they take place a signal
be sent to the main 'perf record' thread, reusing the --switch-output
code to take perf.data snapshots from the --overwrite ring buffer, e.g.:
# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload
will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.
- Add --num-synthesize-threads option to control degree of parallelism of the
synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
time consuming. This mimics pre-existing behaviour in 'perf top'.
perf bench:
- Add a multi-threaded synthesize benchmark.
- Add kallsyms parsing benchmark.
Intel PT support:
- Stitch LBR records from multiple samples to get deeper backtraces,
there are caveats, see the csets for details.
- Allow using Intel PT to synthesize callchains for regular events.
- Add support for synthesizing branch stacks for regular events (cycles,
instructions, etc) from Intel PT data.
Misc changes:
- Updated perf vendor events for power9 and Coresight.
- Add flamegraph.py script via 'perf flamegraph'
- Misc other changes, fixes and cleanups - see the Git log for details.

- Benjamin Herrenschmidt solved a problem with non-matched console
aliases by first checking consoles defined on the command line. It is
a more conservative approach than the previous attempts.
- Benjamin also made sure that the console accessible via /dev/console
always has CON_CONSDEV flag.
- Andy Shevchenko added the %ptT modifier for printing struct time64_t.
It extends the existing %ptR handling for struct rtc_time.
- Bruno Meneguele fixed /dev/kmsg error value returned by unsupported
SEEK_CUR.

The big change in this release is that Matti Vaittinen has factored out
the linear ranges support into a separate library in lib/ since it is
also useful for at least the power subsystem (and most likely others
too), it helps subsystems which need to map register values into more
useful real world values do so with minimal per-driver code.
- Factoring out of the linear ranges support into a library in lib/
from Matti Vaittinen.
- Trace points for bypass mode.
- Use the consumer name in debugfs to make it easier to understand.
- New drivers for Maxim MAX77826 and MAX8998.

This has been a very active release for the DesignWare driver in
particular - after a long period of inactivity we have had a lot of
people actively working on it for unrelated reasons this cycle with some

subsystem. Highlights include:
- Lots of performance improvements and fixes for the DesignWare driver
from Serge Semin, Andy Shevchenko, Wan Ahmad Zainie, Clement Leger,
Dinh Nguyen and Jarkko Nikula.
- Support for octal mode transfers in spidev.
- Slave mode support for the Rockchip drivers.
- Support for AMD controllers, Broadcom mspi and Raspberry Pi 4,

Recently, I switched over from swap-file to zramswap.
When reading the Documentation/vm/zswap.rst file I fell over this typo.
The parameter is called accept_threshold_percent not accept_threhsold_percent
in /sys/module/zswap/parameters/ directory.

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
No Local Variables are initialized for Method [WMNB]
ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.
Method (WMNB, 3, Serialized)
{ ..
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
CreateDWordField (Arg2, 0x0C, IIA3)
CreateDWordField (Arg2, 0x10, IIA4)
Local0 = (Arg1 & 0xFFFFFFFF)
If ((Local0 == 0x54494E49))
..
}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efea ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd03 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.
