Pull sound updates from Takashi Iwai:
"It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features; now it's
built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers; now "make
localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and
managed resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more
modern and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam"

Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Add Intel RAPL energy counter support (Stephane Eranian)

- Optimize ring-buffer writes (Peter Zijlstra)
Tooling side changes, user visible:

directory with guest specific /proc information (Dongsheng Yang)
- Add shell completion support (Ramkumar Ramachandra)
- Add '-v' option (Dongsheng Yang)
- Support --guestmount (Dongsheng Yang)
- 'perf probe':
- Support showing source code, asking for variables to be collected
at probe time and other 'perf probe' operations that use DWARF
information.
This supports only binaries with debugging information at this
time, detached debuginfo (aka debuginfo packages) support should
come in later patches (Masami Hiramatsu)
- 'perf record':
- Rename --no-delay option to --no-buffering, better reflecting its
purpose and freeing up '--delay' to take the place of
'--initial-delay', so that 'record' and 'stat' are consistent
(Arnaldo Carvalho de Melo)
- Default the -t/--thread option to no inheritance (Adrian Hunter)
- Make per-cpu mmaps the default (Adrian Hunter)
- 'perf report':
- Improve callchain processing performance (Frederic Weisbecker)
- Retain bfd reference to lookup source line numbers, greatly
optimizing, among other use cases, 'perf report -s srcline'
(Adrian Hunter)
- Improve callchain processing performance even more (Namhyung Kim)
- Add a perf.data file header window in the 'perf report' TUI,
associated with the 'i' hotkey, providing a counterpart to the
--header option in the stdio UI (Namhyung Kim)
- 'perf script':
- Add an option in 'perf script' to print the source line number
(Adrian Hunter)
- Add --header/--header-only options to 'script' and 'report', the
default is not tho show the header info, but as this has been the
default for some time, leave a single line explaining how to
obtain that information (Jiri Olsa)
- Add options to show comm, fork, exit and mmap PERF_RECORD_ events
(Namhyung Kim)
- Print callchains and symbols if they exist (David Ahern)
- 'perf timechart'

(Stanislav Fomichev)
- 'perf top':
- Make 'perf top -g' refer to callchains, for consistency with
other tools (David Ahern)
- 'perf trace':
- Handle old kernels where the "raw_syscalls" tracepoints were
called plain "syscalls" (David Ahern)

- Honour -m option in 'trace', the tool was offering the option to
set the mmap size, but wasn't using it when doing the actual mmap
on the events file descriptors (Jiri Olsa)
- generic:
- Backport libtraceevent plugin support (trace-cmd repository, with
plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,

build-test) (Namhyung Kim)

being propagated to the feature tests, leading to features being
tested in the host and then being enabled on the target (Mark
Rutland)
- Improve forked workload error reporting by sending the errno in the
signal data queueing integer field, using sigqueue and by doing the
signal setup in the evlist methods, removing open coded equivalents
in various tools (Arnaldo Carvalho de Melo)
- Do more auto exit cleanup chores in the 'evlist' destructor, so
that the tools don't have to all do that sequence (Arnaldo Carvalho

memory in struct pointers to NULL, to help fixing use after free
bugs (Arnaldo Carvalho de Melo)
- Rename some struct DSO binary_type related members and methods, to
clarify its purpose and need for differentiation (symtab_type, ie
one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from (Arnaldo
Carvalho de Melo)

evlist methods that will be used in the IPT patchset (Adrian

Introduces the data structures, constants and symbols needed for
SCHED_DEADLINE implementation.
Core data structure of SCHED_DEADLINE are defined, along with their
initializers. Hooks for checking if a task belong to the new policy
are also added where they are needed.
Adds a scheduling class, in sched/dl.c and a new policy called
SCHED_DEADLINE. It is an implementation of the Earliest Deadline
First (EDF) scheduling algorithm, augmented with a mechanism (called
Constant Bandwidth Server, CBS) that makes it possible to isolate
the behaviour of tasks between each other.
The typical -deadline task will be made up of a computation phase
(instance) which is activated on a periodic or sporadic fashion. The
expected (maximum) duration of such computation is called the task's
runtime; the time interval by which each instance need to be completed
is called the task's relative deadline. The task's absolute deadline
is dynamically calculated as the time instant a task (better, an
instance) activates plus the relative deadline.
The EDF algorithms selects the task with the smallest absolute
deadline as the one to be executed first, while the CBS ensures each
task to run for at most its runtime every (relative) deadline
length time interval, avoiding any interference between different
tasks (bandwidth isolation).
Thanks to this feature, also tasks that do not strictly comply with
the computational model sketched above can effectively use the new
policy.
To summarize, this patch:
- introduces the data structures, constants and symbols needed;
- implements the core logic of the scheduling algorithm in the new
scheduling class file;
- provides all the glue code between the new scheduling class and
the core scheduler and refines the interactions between sched/dl
and the other existing scheduling classes.

the case of the work I've been doing, but there's been quite a lot of
cleanup activity going on and the usual trickle of new drivers:
- Update to the generic DMA code to support deferred probe and managed
resources.
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs.
- Device tree support for the simple card, max98090 and cs42l52.

- More regmap conversions, including a very welcome one for twl6040
