[Sound-open-firmware] [PATCH AUTOSEL 5.9 039/147] ASoC: SOF: fix a runtime pm issue in SOF when HDMI codec doesn't work
by Sasha Levin 05 Nov '20

05 Nov '20

From: Rander Wang <rander.wang(a)intel.com> [ Upstream commit 6c63c954e1c52f1262f986f36d95f557c6f8fa94 ] When hda_codec_probe() doesn't initialize audio component, we disable the codec and keep going. However,the resources are not released. The child_count of SOF device is increased in snd_hdac_ext_bus_device_init but is not decrease in error case, so SOF can't get suspended. snd_hdac_ext_bus_device_exit will be invoked in HDA framework if it gets a error. Now copy this behavior to release resources and decrease SOF device child_count to release SOF device.

[Sound-open-firmware] [PATCH 0/8] use semicolons rather than commas to separate statements
by Julia Lawall 27 Oct '20

27 Oct '20

These patches replace commas by semicolons. This was done using the Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below. This semantic patch ensures that commas inside for loop headers will not be transformed. It also doesn't touch macro definitions. Coccinelle ensures that braces are added as needed when a single-statement branch turns into a multi-statement one. This semantic patch has a few false positives, for variable delcarations such as: LIST_HEAD(x), *y; The semantic patch could be improved to avoid these, but for the moment they have been removed manually (2 occurrences). // <smpl> @initialize:ocaml@ @@ let infunction p = (* avoid macros *) (List.hd p).current_element <> "something_else" let combined p1 p2 = (List.hd p1).line_end = (List.hd p2).line || (((List.hd p1).line_end < (List.hd p2).line) && ((List.hd p1).col < (List.hd p2).col)) @bad@ statement S; declaration d; position p; @@ S@p d // special cases where newlines are needed (hope for no more than 5) @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @@ expression e1,e2; statement S; position p != bad.p; position p1; position p2 : script:ocaml(p1) { infunction p1 && combined p1 p2 }; @@ - e1@p1,@S@p e2@p2; + e1; e2; @r@ expression e1,e2; statement S; position p != bad.p; @@ e1 ,@S@p e2; @@ expression e1,e2; position p1; position p2 : script:ocaml(p1) { infunction p1 && not(combined p1 p2) }; statement S; position r.p; @@ e1@p1 -,@S@p +; e2@p2 ... when any // </smpl> --- sound/firewire/fireworks/fireworks_pcm.c | 2 +- sound/pci/hda/patch_ca0132.c | 2 +- sound/pci/hda/patch_hdmi.c | 2 +- sound/soc/codecs/madera.c | 4 ++-- sound/soc/codecs/wm8350.c | 3 ++- sound/soc/intel/boards/bytcr_rt5651.c | 2 +- sound/soc/samsung/snow.c | 2 +- sound/soc/soc-dapm.c | 2 +- sound/soc/sof/intel/hda-dsp.c | 2 +- 9 files changed, 11 insertions(+), 10 deletions(-)

[Sound-open-firmware] [PATCH v6 0/4] Add a vhost RPMsg API
by Guennadi Liakhovetski 01 Oct '20

Hi, Next update: v6: - rename include/linux/virtio_rpmsg.h -> include/linux/rpmsg/virtio.h v5: - don't hard-code message layout v4: - add endianness conversions to comply with the VirtIO standard v3: - address several checkpatch warnings - address comments from Mathieu Poirier v2: - update patch #5 with a correct vhost_dev_init() prototype - drop patch #6 - it depends on a different patch, that is currently an RFC - address comments from Pierre-Louis Bossart: * remove "default n" from Kconfig Linux supports RPMsg over VirtIO for "remote processor" / AMP use cases. It can however also be used for virtualisation scenarios, e.g. when using KVM to run Linux on both the host and the guests. This patch set adds a wrapper API to facilitate writing vhost drivers for such RPMsg-based solutions. The first use case is an audio DSP virtualisation project, currently under development, ready for review and submission, available at https://github.com/thesofproject/linux/pull/1501/commits Thanks Guennadi Guennadi Liakhovetski (4): vhost: convert VHOST_VSOCK_SET_RUNNING to a generic ioctl rpmsg: move common structures and defines to headers rpmsg: update documentation vhost: add an RPMsg API Documentation/rpmsg.txt | 6 +- drivers/rpmsg/virtio_rpmsg_bus.c | 78 +------ drivers/vhost/Kconfig | 7 + drivers/vhost/Makefile | 3 + drivers/vhost/rpmsg.c | 373 +++++++++++++++++++++++++++++++ drivers/vhost/vhost_rpmsg.h | 74 ++++++ include/linux/rpmsg/virtio.h | 83 +++++++ include/uapi/linux/rpmsg.h | 3 + include/uapi/linux/vhost.h | 4 +- 9 files changed, 551 insertions(+), 80 deletions(-) create mode 100644 drivers/vhost/rpmsg.c create mode 100644 drivers/vhost/vhost_rpmsg.h create mode 100644 include/linux/rpmsg/virtio.h -- 2.28.0

[Sound-open-firmware] [ANNOUNCE] SOF v1.6-rc3 released
by Liam Girdwood 29 Sep '20

29 Sep '20

The SOF developers are pleased to announce the release of our first signed release candidate for v1.6. i.e v1.6-rc3 Binaries can be found here. https://github.com/thesofproject/sof-bin/tree/stable-v1.6 New features are * Support for Intel Tigerlake * Support for Maxim Smart Amplifiers * Beamformer Microphone support. * DC blocker audio processing component. * Major feature and performance improvements for ASRC, KWD and FIR/IIR. * Numerous bug fixes and performance improvements for Intel and NXP platforms. In a change from the previous release process, the later release candidates will now be signed by Intel so that users can have the chance to test drive prior to v1.6 final. This will also give distributions more time to integrate and resolve any issues. Firmware issues can be reported here. https://github.com/thesofproject/sof/issues Thanks Liam

[Sound-open-firmware] A branch can be used as to-be-upstreamed?
by Takashi Iwai 08 Sep '20

08 Sep '20

Hi, as we got a bug report about the new Dell laptop with SoundWire audio, I tried to build a kernel with the downstream SOF patches, then I noticed that it's not so trivial to get the patches from SOF git tree that are applicable on top of upstream (either sound or Linus) tree. Do we have a branch that may contain clean commits on top of the recent upstream? That is, a branch that is regularly rebased, so that each commit can be retrieved as a patch. Such a branch will make upstream submission easier, and it makes easier for distros to take the downstream patches, too. thanks, Takashi
