Merge remote-tracking branch 'airlied/drm-next' into drm-intel-next-queued

Backmerge drm-next to get at all the good stuff in drm-misc. We need
that because:

- drm_connector_list_iter conversion for i915 needs the core patches.
- Maarten's patches to use the new atomic state iterators also need
the core patches.
- We need the new link status property to complete the DP retraining
work, merging through 2 branches wasn't a good idea and we had to
partially backtrack.
- Chris needs reservation_object_trylock and we want to roll out
kref_read everywhere.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"On the kernel side the main changes in this cycle were:

- Add Intel Kaby Lake CPU support (Srinivas Pandruvada)

- AMD uncore driver updates for fam17 (Janakarajan Natarajan)

- Intel/PT updates and core events optimizations and cleanups
(Alexander Shishkin)

- cgroups events fixes (David Carrillo-Cisneros)

- kprobes improvements (Masami Hiramatsu)

- ... plus misc fixes and updates.

On the tooling side the main changes were:

- Support clang build in tools/{perf,lib/{bpf,traceevent,api}} with
CC=clang, to, for instance, take advantage of better warnings
(Arnaldo Carvalho de Melo):

- Introduce the 'delta-abs' 'perf diff' compute method, that orders
the histogram entries by the absolute value of the percentage delta
for a function in two perf.data files, i.e. the functions that
changed the most (increase or decrease in samples) comes first
(Namhyung Kim)

- Add support for parsing Intel uncore vendor event files and add
uncore vendor events for the Intel server processors (Haswell,
Broadwell, IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE
(Andi Kleen)

- Introduce 'perf ftrace' a perf front end to the kernel's ftrace
function and function_graph tracer, defaulting to the
"function_graph" tracer, more work will be done in reviving this
effort, forward porting it from its initial patch submission
(Namhyung Kim)

- Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)

- Account thread wait time (off CPU time) separately: sleep, iowait
and preempt, based on the prev_state of the last event, show the
breakdown when using "perf sched timehist --state" (Namhyumg Kim)

- Add more triggers to switch the output file (perf.data.TIMESTAMP).

Now, in addition to switching to a different output file when
receiving a SIGUSR2, one can also specify file size and time based
triggers:

perf record -a --switch-output=signal

is equivalent to what we had before:

perf record -a --switch-output

While we can also ask for the file to be "sliced" by size, taking
into account that that will happen only when we get woken up by the
kernel, i.e. one has to take into account the --mmap-pages (the
size of the perf mmap ring buffer):

perf record -a --switch-output=2G

will break the perf.data output into multiple files limited to 2GB
of samples, right when generating the output.

For time based samples, alert() will be used, so to have 1 minute
limited perf.data output files:

perf record -a --switch-output=1m

(Jiri Olsa)

- Improve 'perf trace' (Arnaldo Carvalho de Melo)

- 'perf kallsyms' toy tool to look for extended symbol information on
the running kernel and demonstrate the machine/thread/symbol APIs
for use in other tools, such as 'perf probe' (Arnaldo Carvalho de
Melo)

- ... plus tons of other changes, see the shortlog and Git log for
details"

Pull perf/core clang fixes from Arnaldo Carvalho de Melo:

Changes to make tools/{perf,lib/{bpf,traceevent,api}} build with
CC=clang, to, for instance, take advantage of warnings (Arnaldo Carvalho de Melo):

- Conditionally request some warning options not available on clang

- Set the maximum optimization level to -O3 when using CC=clang, leave
the previous setting of -O6 otherwise.

- Make it an error to pass a signed value to OPTION_UINTEGER, so that
we can remove abs(unsigned int) calls in 'perf bench futex'.

- Make sure dprintf() is not defined before using that name in 'perf bench numa'

- Avoid using field after variable sized type, its a GNU extension, use
equivalent code.

- Fix some bugs where some variables could be used unitialized,
something not caught by gcc.

- Fix some spots where we were testing struct->array[] members against
NULL, it will always evaluate to 'true'.

- Add missing parse_events_error() prototype in the bison file.

There are still one problem when trying to build the python support, but
this are the 'size' outputs for 'make -C tools/perf NO_LIBPYTHON' for
gcc and clang builds:

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"With over 300 commits it's been a busy cycle - with most of the work
concentrated on the tooling side (as it should).

The main kernel side enhancements were:

- Add per event callchain limit: Recently we introduced a sysctl to
tune the max-stack for all events for which callchains were
requested:

$ sysctl kernel.perf_event_max_stack
kernel.perf_event_max_stack = 127

Now this patch introduces a way to configure this per event, i.e.
this becomes possible:

$ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a

allowing finer tuning of how much buffer space callchains use.

This uses an u16 from the reserved space at the end, leaving
another u16 for future use.

There has been interest in even finer tuning, namely to control the
max stack for kernel and userspace callchains separately. Further
discussion is needed, we may for instance use the remaining u16 for
that and when it is present, assume that the sample_max_stack
introduced in this patch applies for the kernel, and the u16 left
is used for limiting the userspace callchain (Arnaldo Carvalho de
Melo)

- Optimize AUX event (hardware assisted side-band event) delivery
(Kan Liang)

- Rework Intel family name macro usage (this is partially x86 arch
work) (Dave Hansen)

- Refine and fix Intel LBR support (David Carrillo-Cisneros)

- Add support for Intel 'TopDown' events (Andi Kleen)

- Intel uncore PMU driver fixes and enhancements (Kan Liang)

- ... other misc changes.

Here's an incomplete list of the tooling enhancements (but there's
much more, see the shortlog and the git log for details):

- Support cross unwinding, i.e. collecting '--call-graph dwarf'
perf.data files in one machine and then doing analysis in another
machine of a different hardware architecture. This enables, for
instance, to do:

$ perf record -a --call-graph dwarf

on a x86-32 or aarch64 system and then do 'perf report' on it on a
x86_64 workstation (He Kuang)

- Allow reading from a backward ring buffer (one setup via
sys_perf_event_open() with perf_event_attr.write_backward = 1)
(Wang Nan)

- Finish merging initial SDT (Statically Defined Traces) support, see
cset comments for details about how it all works (Masami Hiramatsu)

- Support attaching eBPF programs to tracepoints (Wang Nan)

- Add demangling of symbols in programs written in the Rust language
(David Tolnay)

- Add support for tracepoints in the python binding, including an
example, that sets up and parses sched:sched_switch events,
tools/perf/python/tracepoint.py (Jiri Olsa)

- Introduce --stdio-color to set up the color output mode selection
in 'annotate' and 'report', allowing emit color escape sequences
when redirecting the output of these tools (Arnaldo Carvalho de
Melo)

- Add 'callindent' option to 'perf script -F', to indent the Intel PT
call stack, making this output more ftrace-like (Adrian Hunter,
Andi Kleen)

- Allow dumping the object files generated by llvm when processing
eBPF scriptlet events (Wang Nan)

- Add stackcollapse.py script to help generating flame graphs (Paolo
Bonzini)

- Add --ldlat option to 'perf mem' to specify load latency for loads
event (e.g. cpu/mem-loads/ ) (Jiri Olsa)

- Tooling support for Intel TopDown counters, recently added to the
kernel (Andi Kleen)"

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

User visible changes:

- Add demangling of symbols in programs written in the Rust language (David Tolnay)

- Add support for tracepoints in the python binding, including an example, that

(Jiri Olsa)

- Introduce --stdio-color to set up the color output mode selection in
'annotate' and 'report', allowing emit color escape sequences when
redirecting the output of these tools (Arnaldo Carvalho de Melo)

Infrastructure changes:

- Various tweaks to allow the 'perf trace' beautifiers to build without using
kernel headers and in a wider range of Linux distributions/releases
(Arnaldo Carvalho de Melo)

- Stop using kernel source files, instead copy what is needed and
check when the original kernel source file gets modified, warning
the developers about it. This helps in building the tool in older
systems and even in recent ones, for just added kernel features
for which ABI details (struct changes, defines, etc) still are not
available on system headers (Arnaldo Carvalho de Melo)

- Be consistent in how to use strerror_r, adding a wrapper that makes sure that
it returns a pointer to passed buffer, and using the XSI variant, that is
available in more libc implementations (Arnaldo Carvalho de Melo)

- Avoid checking code drift on busibox's diff perf intel-pt-decoder, as it
doesn't have the '-I' command line switch to check for regexps
(Arnaldo Carvalho de Melo)

- Add missing headers in various places (Arnaldo Carvalho de Melo)

- Remove unneeded headers from various other places (Arnaldo Carvalho de Melo)

- Add feature detection for gelf_getnote(), disabling SDT support if not
present (Arnaldo Carvalho de Melo)

- Fix oddities with GCC 5.3.0 by initializing some variables
(Arnaldo Carvalho de Melo)

- With those changes in place perf now builds on Alpine Linux 3.4, in addition to
on centos (5, 6, 7), debian (7, 8, experimental), fedora (21, 22, 23, 24, rawhide),
mageia 5, opensuse (13.2, 42.1) and ubuntu (12.04.5, 14.04.4, 15.10, 16.04) and
will be test build on those systems prior to future pull requests.
