  • 69116f279   module_param: avoid bool abuse, add bint for special cases. ... Browse Code »

    For historical reasons, we allow module_param(bool) to take an int (or
    an unsigned int). That's going away.

    A few drivers really want an int: they set it to -1 and a parameter
    will set it to 0 or 1. This sucks: reading them from sysfs will give
    'Y' for both -1 and 1, but if we change it to an int, then the users
    might be broken (if they did "param" instead of "param=1").

    Use a new 'bint' parser for them.

    (ntfs has a different problem: it needs an int for debug_msgs because
    it's also exposed via sysctl.)

    module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

    Detection code improved by PCI SSID usage. VM optimization
    now enabled only for known devcices (skip host devices forwarded
    to VM by VT-d or same kind of technology).
    For debug/troubleshooting purposes optimization can be
    forced (on/off) by module parameter: "inside_vm" (boolean).

    Known devices (PCI SSID):
    1af4:1100: Reserved for KVM devices. Note this is not yet
    implemented for KVM's ICH/AC'97 emulation.
    1ab8:xxxx: Parallels ICH/AC'97 emulated sound.

    The recently merged 228cf79376f1 looks a bit hackish while it is not.
    The change was quite simple. In a virtualized environment the
    patch unhacks old kludge introduced for old broken AC97 hardware.

    This patch adds proper comment to "unkludge" code.

  • 228cf7937   ALSA: intel8x0: Improve performance in virtual environment ... Browse Code »

    v3: detection code is x86 and KVM specific, hide it under ifdef
    v2: add detection for virtual environments (KVM and Parallels)

    This patch is intended to improve performance in virtualized environments
    like Parallels Desktop or KVM/VirtualBox/QEMU (virtual ICH/AC97 audio).

    I/O access is very time-expensive operation in virtual world: VCPU
    can be rescheduled and in the worst case we get more than 10ms delay on
    each I/O access.

    In the virtual environment loop exit rule
    (old_civ == current_civ && old_picb == current_picb) is never satisfied,
    because old_picb is never the same as current_picb due to delay inspired
    by reading current_civ. As a result loop ended by timeout and we get 10x
    more I/O operations.

    Experimental data from Prallels Desktop 7, RHEL6 guest (I/O ops per
    second):

    Original code:
    In Port Counter Callback
    f014 41550 fffff00000179d00 ac97_bm_read_civ+0x000

    The name argument of request_irq() appears in /proc/interrupts, and
    it's quite ugly when the name entry contains a space or special letters.
    In general, it's simpler and more readable when the module name appears
    there, so let's replace all entries with KBUILD_MODNAME.

  • 3733e424c   ALSA: Use KBUILD_MODNAME for pci_driver.name entries ... Browse Code »

    The convention for pci_driver.name entry in kernel drivers seem to be
    the module name or equivalent ones. But, so far, almost all PCI sound
    drivers use more verbose name like "ABC Xyz (12)", and these are fairly
    confusing when appearing as a file name.

    This patch converts the all pci_driver.name entries in sound/pci/* to
    use KBUILD_MODNAME for more unified appearance.

    BugLink: https://launchpad.net/bugs/669279

    The original reporter states: "The Master mixer does not change the
    volume from the headphone output (which is affected by the headphone
    mixer). Instead it only seems to control the on-board speaker volume.
    This confuses PulseAudio greatly as the Master channel is merged into
    the volume mix."

    Fix this symptom by applying the hp_only quirk for the reporter's SSID.
    The fix is applicable to all stable kernels.

  • f708eb1d7   ALSA: intel8x0 - Fix PCM position craziness ... Browse Code »

    The PCM pointer callback sometimes returns invalid positions and this
    screws up the hw_ptr updater in PCM core. Especially since now the
    jiffies check is optional with xrun_debug, the invalid position is
    handled as is, and causes serious sound skips, etc.

    This patch simplifies the position-fix strategy in intel8x0 to be more
    robust:
    - just falls back to the last position if bogus position is detected
    - another sanity check for the backward move of the position due to
    a race of register update and the base-index update

    This patch is applicable also for 2.6.30.
