| * | | | ALSA: hda - Fix audio crackles on Dell Latitude E7x40Takashi Iwai2015-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We still got a report that the audio crackles and noises occur with the recent 4.1 kernels on Dell machines. These machines seem to need similar workarounds that have been applied to the recent Dell XPS 13 models. Since the codec of these machines (Dell Latitute E7240 and E7440) is different from XPS 13's one, we need a new fixup entry. Also, it was confirmed that the previous workaround to disable the widget power-save (commit [219f47e4f964: ALSA: hda - Disable widget power-saving for ALC292 & co]) is no longer needed after this fix. So, this patch includes the partial revert of the commit, too.

For for simplicity reason, we haven't implemented abort even for controller chips that are dedicated for HDMI/DP on HSW and BDW. However, Mengdong suggested that this can be dangerous; BIOS may disable gfx power well although the PCI entry for HD-audio is left, and this may result in the unexpected behavior, kernel errors, etc. For avoiding this situation, abort the probe at i915 binding failure only for HSW/BDW chips selectively. For other chips, it still continues.

Since the bits 4-7 are unused for the amp registers (as we follow the syntax of AMP_GET verb), the bit 4 is now used to indicate the fake mute. For setting this flag, snd_hda_codec_amp_update() becomes a function from a simple macro. The bonus is that it gained a proper function description. Signed-off-by: Takashi Iwai <tiwai@suse.de>

This is no big problem for Haswell and Broadwell where the HD-audio controllers are dedicated to HDMI/DP, thus i915 link is mandatory. However, Skylake, Baytrail and Braswell have only one controller and both HDMI/DP and analog codecs share the same bus. Thus, even if HDMI/DP isn't usable, we should keep the controller working for other codecs. For fixing this, this patch simply allows continuing the probing even if hda_i915_init() call fails. This may leave stale sound components for HDMI/DP devices that are unbound with graphics. We could abort the probing selectively, but from the code simplicity POV, it's better to continue in all cases.

Through the regression report, it was revealed that the tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the mute LED but actually mutes the sound. This is contradiction to the expectation, and rather confuses user. According to Henrique, it's not trivial to judge which TP model behaves "LED-only" and which model does whatever more intrusive, as Lenovo's implementations vary model by model. So, from the safety reason, we should revert the patch for now.

| | | | | | | | | | | | | | It's very unlikely that we'd need these fields out of sudden. Let's drop them. Signed-off-by: Takashi Iwai <tiwai@suse.de>
* | ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FSJie Yang2015-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | We may disable proc fs only for sound part, to reduce ALSA memory footprint. So add CONFIG_SND_PROC_FS and replace the old CONFIG_PROC_FSs in alsa code. With sound proc fs disabled, we can save about 9KB memory size on X86_64 platform.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | PCI_DEVICE() macro itself defines SSID entries while we override them after that. Replace with a more appropriate macro, PCI_DEVICE_SUB() to define all ID values properly.

* | ALSA: hda - Move hda_i915.c from sound/pci/hda to sound/hdaMengdong Lin2015-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file is moved to hda core and renamed to hdac_i915.c, so can be used by both legacy HDA driver and new Skylake audio driver. - Add snd_hdac_ prefix to the public APIs. - The i915 audio component is moved to core bus and dynamically allocated. - A static pointer hdac_acomp is used to help bind/unbind callbacks to get this component, because the sound card's private_data is used by the azx chip pointer, which is a legacy structure. It could be removed if private _data changes to some core structure which can be extended to find the bus. - snd_hdac_get_display_clk() is added to get the display core clock for HSW/BDW. - haswell_set_bclk() is moved to hda_intel.c because it needs to write the controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW. - Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have different layout for the extended mode registers.
