Merge branch 'for-6.15/amd_sfh' into for-linus

From: Mario Limonciello <mario.limonciello@amd.com>

Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.

Example use cases are "wake from suspend on approach" or to "lock
when leaving".

This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.

Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

Covert as follows:

$(if A,A,B) --> $(or A,B)

This patch also converts:

$(if A, A, B) --> $(or A, B)

Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".

Anyway, preceding spaces are not significant in the code hunks I touched.

Merge tag 'perf-core-for-mingo-5.2-20190517' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

perf.data:

Alexey Budankov:

- Streaming compression of perf ring buffer into PERF_RECORD_COMPRESSED
user space records, resulting in ~3-5x perf.data file size reduction
on variety of tested workloads what saves storage space on larger
server systems where perf.data size can easily reach several tens or
even hundreds of GiBs, especially when profiling with DWARF-based
stacks and tracing of context switches.

perf record:

Arnaldo Carvalho de Melo

- Improve -user-regs/intr-regs suggestions to overcome errors.

perf annotate:

Jin Yao:

- Remove hist__account_cycles() from callback, speeding up branch processing
(perf record -b).

perf stat:

- Add a 'percore' event qualifier, e.g.: -e cpu/event=0,umask=0x3,percore=1/,
that sums up the event counts for both hardware threads in a core.

We can already do this with --per-core, but it's often useful to do
this together with other metrics that are collected per hardware thread.

I.e. now its possible to do this per-event, and have it mixed with other
events not aggregated by core.

core libraries:

Donald Yandt:

- Check for errors when doing fgets(/proc/version).

Jiri Olsa:

- Speed up report for perf compiled with linbunwind.

tools headers:

Arnaldo Carvalho de Melo

- Update memcpy_64.S, x86's kvm.h and pt_regs.h.

arm64:

Florian Fainelli:

- Map Brahma-B53 CPUID to cortex-a53 events.

- Add Cortex-A57 and Cortex-A72 events.

csky:

Mao Han:

- Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work
on the C-SKY arch.

x86:

Andi Kleen/Kan Liang:

- Add support for recording and printing XMM registers, available, for
instance, on Icelake.

Kan Liang:

- Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
UPI replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP.

Intel PT:

Adrian Hunter

. Fix instructions sampling rate.

. Timestamp fixes.

. Improve exported-sql-viewer GUI, allowing, for instance, to copy'n'paste
the trees, useful for e-mailing.

Documentation:

Thomas Richter:

- Add description for 'perf --debug stderr=1', which redirects stderr to stdout.

libtraceevent:

Tzvetomir Stoyanov:

- Add man pages for the various APIs.
