ALSA: hda: Fix 1-minute detection delay when i915 module is not available

2019-08-06T17:08:17+00:00

commit 74bf71ed792ab0f64631cc65ccdb54c356c36d45 upstream. Distribution installation images such as Debian include different sets of modules which can be downloaded dynamically. Such images may notably include the hda sound modules but not the i915 DRM module, even if the latter was enabled at build time, as reported on https://bugs.debian.org/931507 In such a case hdac_i915 would be linked in and try to load the i915 module, fail since it is not there, but still wait for a whole minute before giving up binding with it. This fixes such as case by only waiting for the binding if the module was properly loaded (or module support is disabled, in which case i915 is already compiled-in anyway).

ALSA: hda: Fix a headphone detection issue when using SOF

2019-07-26T07:10:42+00:00

[ Upstream commit 7c2b3629d09ddec810dc4c1d3a6657c32def8f71 ] To save power, the hda hdmi driver in ASoC invokes snd_hdac_ext_bus_link_put to disable CORB/RIRB buffers DMA if there is no user of bus and invokes snd_hdac_ext_bus_link_get to set up CORB/RIRB buffers when it is used. Unsolicited responses is disabled in snd_hdac_bus_stop_cmd_io called by snd_hdac_ext_bus_link_put , but it is not enabled in snd_hdac_bus_init_cmd_io called by snd_hdac_ext_bus_link_get. So for put-get sequence, Unsolicited responses is disabled and headphone can't be detected by hda codecs. Now unsolicited responses is only enabled in snd_hdac_bus_reset_link which resets controller. The function is only called for setup of controller. This patch enables Unsolicited responses after RIRB is initialized in snd_hdac_bus_init_cmd_io which works together with snd_hdac_bus_reset_link to set up controller. Tested legacy hda driver and SOF driver on intel whiskeylake. Reviewed-by: Takashi Iwai Signed-off-by: Rander Wang Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin

ALSA: hdac: Fix codec name after machine driver is unloaded and reloaded

2019-07-26T07:10:35+00:00

[ Upstream commit 8a5b0177a7f6099ff534a4d9ce72673af5c3cade ] Currently on each driver reload internal counter is being increased. It causes failure to enumerate driver devices, as they have hardcoded: .codec_name = "ehdaudio0D2", As there is currently no devices with multiple hda codecs and there is currently no established way to reliably differentiate, between them, always assign bus->idx = 0; This fixes a problem when we unload and reload machine driver idx gets incremented, so .codec_name would've needed to be set to "ehdaudio1D2" after first reload and so on.

ALSA: hda: Fix widget_mutex incomplete protection

2019-07-01T18:13:04+00:00

The widget_mutex was introduced to serialize callers to hda_widget_sysfs_{re}init. However, its protection of the sysfs widget array is incomplete. For example, it is acquired around the call to hda_widget_sysfs_reinit(), which actually creates the new array, but isn't still acquired when codec->num_nodes and codec->start_nid is updated. So the lock ensures one thread sets up the new array at a time, but doesn't ensure which thread's value will end up in codec->num_nodes. If a larger num_nodes wins but a smaller array was set up, the next call to refresh_widgets() will touch free memory as it iterates over codec->num_nodes that aren't there. The widget_lock really protects both the tree as well as codec->num_nodes, start_nid, and end_nid, so make sure it's held across that update. It should also be held during snd_hdac_get_sub_nodes(), so that a very old read from that function doesn't end up clobbering a later update.

ASoC: Fixes for v5.2 There's an awful lot of fixes here, almost all for the newly introduced SoF DSP drivers (including a few things it turned up in shared code). This is a large and complex piece of code so it's not surprising that there have been quite a few issues here, fortunately things seem to have mostly calmed down now. Otherwise there's just a smattering of small fixes.

ALSA: hdac: fix memory release for SST and SOF drivers

2019-06-06T16:37:01+00:00

During the integration of HDaudio support, we changed the way in which we get hdev in snd_hdac_ext_bus_device_init() to use one preallocated with devm_kzalloc(), however it still left kfree(hdev) in snd_hdac_ext_bus_device_exit(). It leads to oopses when trying to rmmod and modprobe. Fix it, by just removing kfree call. SOF also uses some of the snd_hdac_ functions for HDAudio support but allocated the memory with kzalloc. A matching fix is provided separately to align all users of the snd_hdac_ library.
