[alsa-devel] code improvements in /sound/usb/mixer.c
by Daniel Schürmann 25 Apr '13

25 Apr '13

Hi Takashi, Hi alsa-devel. in my last mail I had supposed scaling issues with mixer.c, but finally it turns out that was just a debugging problem of myself. I was struggled how types are handled in the code. I have some ideas for improvement but I am not sure if it its worth the work since nothing is broken. 1. get rid of convert_bytes_value(cval, value_set): This function return any type in a integer container, which is confusing. 2. use type casts in convert_signed_value(): gcc knows perfecly how to convert types. 3. merge convert_signed_value() and snd_usb_combine_bytes() to get rid of the intermediate integer variant. --- I am currently working on a patch that introduces a get_ctl_value_range_v2. I want to get rid of the three single queries for min max and rate. Also here, nothing broken. Is it worth to do the work? Kind regards Daniel

[alsa-devel] [PATCH v2] ALSA: snd-usb-audio: fixed mixer range reading during probing, when compiled with CONFIG_PM defined
by Daniel Schürmann 25 Apr '13

25 Apr '13

During probing, snd_usb_autoresume() fails with -ENODEV. This brakes get_ctl_value() in mixer.c when reading the range values. In the new version snd_usb_autoresume() returns 0 in this case which brakes not the following query. The following snd_usb_suspend() fails silently during probing anyway. The patch also makes the error messages more significant. The original error messages where identified as misleading during debug.

[alsa-devel] Asynchronous audio USB chips: choppy playback since 3.8-rc7
by David Henningsson 24 Apr '13

24 Apr '13

Hi ALSA developers, Just to get your attention here on what seems to be an USB audio regression. The bug is described in detail here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1136110?comments=all Quoting the bug: " This bug seems to affect only a certain kind of hardware, which is called "Asynchronous USB Digital Audio Codec (DAC)". It's said that such a DAC hosts the clock itself (USB Device Host). An ordinary DAC, so called "Synchronous USB DAC", uses the clock hosted by the mother board, which is not affected by this bug. When this bug affects an asynchronous USB DAC, the audio played by the DAC is constantly interrupted. The playback itself does not stop, but the output becomes discontinous, filling with constant crackling noises, destroying everything the DAC plays. " According to the bug reporter, which seems to have done quite a bit of research, this started between 3.8-rc6 and 3.8-rc7 as well as stable kernels and the bug also lists a few commits which could be the cause, none under sound/usb though. -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic

During probing, snd_usb_autoresume() failes with -ENODEV. This brakes get_ctl_value() in mixer.c when rading the range values. The new code does not try to call snd_usb_autoresume() in this case.

Re: [alsa-devel] [PATCH] drm/i915: Add private api for power well usage
by Wang, Xingchao 24 Apr '13

24 Apr '13

Hi Guys, Sorry I should Add Takashi and alsa maillist in loop. I tested this patch against Daniel's "drm-intel-next-queued" Branch, on Haswell Mobile C3 stepping machines. Test steps: 1. only connect one monitor through HDMI cable 2. echo 1 > /sys/module/i915/parameters/disable_power_well ==> I think this could be set as 1 by default if applied my patch. 3. plug out HDMI cable 4. cat /proc/asound/card0/codec#0 At step 3, i915 will try to disable power well but rejected as display audio is using power well. Without the patch, display audio would crash at step 4. I did not list suspend/resume test here, as during suspend sequence, i915 will _ENABLE_ power well, that's a BUG? For me above test case is the only one to reproduce the issue, if you have more ideas and need more test, please let me know. I'm afraid there's some risk because the dependency between alsa driver and drm driver. For example, if i915 module was not loaded, display audio Will call request_power_well() and meet symbol error. Even if i915 module loaded after snd-hda-intel module, there's such risk too. Any comment on this? Another risk is the pointer "power_well_device", it should be set NULL when i915 module unloaded, I added the caller but have no idea where to call it, if anyone has suggestion, that would be fine. thanks --xingchao > -----Original Message----- > From: Wang Xingchao [mailto:xingchao.wang@linux.intel.com] > Sent: Thursday, April 24, 2014 10:20 PM > To: daniel.vetter(a)ffwll.ch; Zanoni, Paulo R > Cc: ville.syrjala(a)linux.intel.com; Lin, Mengdong; Girdwood, Liam R; Li, Jocelyn; > intel-gfx(a)lists.freedesktop.org; Wang, Xingchao; Wang Xingchao > Subject: [PATCH] drm/i915: Add private api for power well usage > > Display audio depends on power well in graphic side, it should request power > well before use it and release power well after use. > I915 will not shutdown power well if it detects audio is using. > This patch protects display audio crash for Intel Haswell mobile > C3 stepping board. > > Signed-off-by: Wang Xingchao <xingchao.wang(a)linux.intel.com> > --- > drivers/gpu/drm/i915/intel_pm.c | 73 > +++++++++++++++++++++++++++++++++++---- > include/drm/audio_drm.h | 39 +++++++++++++++++++++ > sound/pci/hda/hda_intel.c | 8 +++++ > 3 files changed, 113 insertions(+), 7 deletions(-) create mode 100644 > include/drm/audio_drm.h > > diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c > index 2557926..9983f56 100644 > --- a/drivers/gpu/drm/i915/intel_pm.c > +++ b/drivers/gpu/drm/i915/intel_pm.c > @@ -4298,18 +4298,12 @@ bool intel_using_power_well(struct drm_device > *dev) > return true; > } > > -void intel_set_power_well(struct drm_device *dev, bool enable) > +void set_power_well(struct drm_device *dev, bool enable) > { > struct drm_i915_private *dev_priv = dev->dev_private; > bool is_enabled, enable_requested; > uint32_t tmp; > > - if (!HAS_POWER_WELL(dev)) > - return; > - > - if (!i915_disable_power_well && !enable) > - return; > - > tmp = I915_READ(HSW_PWR_WELL_DRIVER); > is_enabled = tmp & HSW_PWR_WELL_STATE; > enable_requested = tmp & HSW_PWR_WELL_ENABLE; @@ -4332,6 > +4326,71 @@ void intel_set_power_well(struct drm_device *dev, bool enable) > } > } > > +/* Global drm_device for display audio drvier usage */ static struct > +drm_device *power_well_device; static bool audio_power_well_using, > +i915_power_well_using; > +/* Lock protecting power well setting */ > +DEFINE_SPINLOCK(powerwell_lock); > + > +void request_power_well(void) > +{ > + DRM_DEBUG_KMS("Display audio requesting power well\n"); > + spin_lock_irq(&powerwell_lock); > + if (!power_well_device) > + goto out; > + if (i915_power_well_using == false) > + set_power_well(power_well_device, true); > + audio_power_well_using = true; > +out: > + spin_unlock_irq(&powerwell_lock); > + return; > +} > +EXPORT_SYMBOL_GPL(request_power_well); > + > +void release_power_well(void) > +{ > + DRM_DEBUG_KMS("Display audio releasing power well\n"); > + spin_lock_irq(&powerwell_lock); > + if (!power_well_device) > + goto out; > + if (i915_power_well_using == false) > + set_power_well(power_well_device, false); > + audio_power_well_using = false; > +out: > + spin_unlock_irq(&powerwell_lock); > + return; > +} > +EXPORT_SYMBOL_GPL(release_power_well); > + > +/* TODO: Call this when i915 module unload */ void > +remove_power_well(void) { > + spin_lock_irq(&powerwell_lock); > + audio_power_well_using = false; > + i915_power_well_using = false; > + power_well_device = NULL; > + spin_unlock_irq(&powerwell_lock); > +} > + > +void intel_set_power_well(struct drm_device *dev, bool enable) { > + if (!HAS_POWER_WELL(dev)) > + return; > + > + spin_lock_irq(&powerwell_lock); > + power_well_device = dev; > + i915_power_well_using = enable; > + if (!enable && audio_power_well_using) > + goto out; > + > + if (!i915_disable_power_well && !enable) > + goto out; > + set_power_well(dev, enable); > +out: > + spin_unlock_irq(&powerwell_lock); > + return; > +} > + > /* > * Starting with Haswell, we have a "Power Down Well" that can be turned off > * when not needed anymore.
