    "As the diffstat shows we've had again a lot of works done for this
    cycle: the majority of changes are the continued componentization and
    code refactoring in ASoC, the tree-wide PCM API updates and cleanups
    and SOF updates while a few ASoC driver updates are seen, too.

    Here we go, some highlights:

    Core:
    - Finally y2038 support landed to ALSA ABI; some ioctls have been
    extended and lots of tricks were applied
    - Applying the new managed PCM buffer API to all drivers; the API
    itself was already merged in 5.5
    - The already deprecated dimension support in ALSA control API is
    dropped completely now
    - Verification of ALSA control elements to catch API misuses

    ASoC:
    - Further code refactorings and moving things to the component level
    - Lots of updates and improvements on SOF / Intel drivers; now
    including common HDMI driver and SoundWire support
    - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
    WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011,
    RT1015 and RT1308

    HD-audio:
    - Improved ring-buffer communications using waitqueue
    - Drop the superfluous buffer preallocation on x86

    Others:
    - Many code cleanups, mostly constifications over the whole tree
    - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
    - FireWire: code refactoring for oxfw and dice drivers"

  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

    Pull sound updates from Takashi Iwai:
    "We have touched quite a lot of files but with fewer changes at this
    cycle; as you can see, most of changes are trivial fixes, especially
    constification patches.

    Among the massive attacks by constification gangs, we had a few core
    changes (mostly for ASoC core), as well the fixes and the updates by
    major vendors.

    Some highlights:

    ALSA core:

    - Fix possible races in control API user-TLV codes

    - Small cleanup of PCM core

    ASoC:

    - Continued work for componentization; still half-baked, but we're
    certainly progressing

    - Use of devres for jack detection GPIOs, rather as a cleanup

    - Jack detection support for Qualcomm MSM8916

  • e8e0929d7   ALSA: sound/parisc: Move dereference after NULL test ... Browse Code »

    If the NULL test on h is needed in snd_harmony_mixer_init, then the
    dereference should be after the NULL test.

    Actually, there is a sequence of calls: snd_harmony_create, then
    snd_harmony_pcm_init, and then snd_harmony_mixer_init. snd_harmony_create
    initializes h, but may indeed leave it as NULL. There was no NULL test at
    the beginning of snd_harmony_pcm_init, so I have added one. The NULL test
    in snd_harmony_mixer_init is then not necessary, but in case the ordering
    of the calls changes, I have left it, and moved the dereference after it.

    A simplified version of the semantic match that detects this problem is as
    follows (http://coccinelle.lip6.fr/):

    //
    @match exists@
    expression x, E;
    identifier fld;
    @@

    * x->fld
    ... when != \(x = E\|&x\)
    * x == NULL

  • 9004acc70   [ALSA] Remove sound/driver.h ... Browse Code »

    This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.
