[PATCH] ASoC: cs42l56: fix DT probe
by Arnd Bergmann 26 Jan '23

26 Jan '23

From: Arnd Bergmann <arnd(a)arndb.de> While looking through legacy platform data users, I noticed that this one could never be used with DT based probing as the platform_data structure gets overwritten directly after it is initialized. There have never been any boards defining the platform_data in the mainline kernel either, so this driver so far only worked with patched kernels. For the benefit of possible downstream users, fix the DT probe by no longer overwriting the data.

[PATCH] ALSA: memalloc: Workaround for Xen PV
by Takashi Iwai 26 Jan '23

26 Jan '23

We change recently the memalloc helper to use dma_alloc_noncontiguous() and the fallback to get_pages(). Although lots of issues with IOMMU (or non-IOMMU) have been addressed, but there seems still a regression on Xen PV. Interestingly, the only proper way to work is use dma_alloc_coherent(). The use of dma_alloc_coherent() for SG buffer was dropped as it's problematic on IOMMU systems. OTOH, Xen PV has a different way, and it's fine to use the dma_alloc_coherent(). This patch is a workaround for Xen PV. It consists of the following changes: - For Xen PV, use only the fallback allocation without dma_alloc_noncontiguous() - In the fallback allocation, use dma_alloc_coherent(); the DMA address from dma_alloc_coherent() is returned in get_addr ops - The DMA addresses are stored in an array; the first entry stores the number of allocated pages in lower bits, which are referred at releasing pages again Reported-by: Marek Marczykowski-Górecki <marmarek(a)invisiblethingslab.com> Fixes: a8d302a0b770 ("ALSA: memalloc: Revive x86-specific WC page allocations again") Fixes: 9736a325137b ("ALSA: memalloc: Don't fall back for SG-buffer with IOMMU") Link: https://lore.kernel.org/r/87tu256lqs.wl-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai(a)suse.de> --- Marek, this is another respin of the fix.

Best way to add support a USB audio device where only the second usb configuration works
by Marijn Kruisselbrink 26 Jan '23

26 Jan '23

(disclaimer: I'm fairly new to kernel stuff, alsa and low level usb things in general, so my terminology might all not be correct, and I might be missing obvious stuff, but:) I've been trying (and succeeding) to get a SoundDevices MixPre II 10 to work well under linux. What I figured out is that this device advertises two usb configurations. The first configuration claims to be a UAC1 interface, exposing stereo in and output channels. This configuration isn't actually class compliant though, or at least neither playback nor recording are working right with this configuration. The second configuration on the other hand claims to be a UAC2 interface, exposing the full 12 in and 4 output channels the device is supposed to support. And in this configuration everything I've tried seems to work perfectly. I'm not sure what the best/cleanest way would to actually make snd-usb-audio/the linux kernel select this second configuration. In my experimenting I made this work by adding a usb_device_driver to snd-usb-audio that makes sure to select the second configuration for this particular USB device. Is that the right approach? Or would it be better for this to be an entirely separate module? I also wonder if this is something that would make sense to address in the generic usb driver's usb_choose_configuration method? Currently it seems that for audio devices it always picks the first configuration, unless one of the configurations uses the UAC3 protocol (in which case it picks the first UAC3 configuration). For this device in question, the first (non compliant/non functioning) configuration claims to use UAC1 protocol, while the second (and seemingly functioning completely fine) configuration uses UAC2. Should the generic logic prefer UAC2 configurations over UAC1 configurations, like it already prefers UAC3 configurations over anything else? Or is there a particular reason why UAC2 doesn't get that treatment? Or maybe I'm missing some other way of making sure this second configuration is used for this device? Thanks for any advice/help you can give me, Marijn

[PATCH v1] ASoC: qcom: lpass-platform: Use SNDRV_DMA_TYPE_NONCOHERENT page allocation
by Judy Hsiao 26 Jan '23

26 Jan '23

Replace SNDRV_DMA_TYPE_DEV by SNDRV_DMA_TYPE_NONCOHERENT for pcm buffer allocation. We measured about 18x performance improvement when accessing the snd_pcm_mmap() buffer from userspace. Eg: aarch64 with internal speaker == SNDRV_DMA_TYPE_DEV frames_per_second=66.4557M/s max_time_per_4096_frames=106.094u time_per_4096_frames=61.6351us SNDRV_DMA_TYPE_NONCOHERENT frames_per_second=1028.58M/s max_time_per_4096_frames=20.312u time_per_4096_frames=3.98221us Signed-off-by: Judy Hsiao <judyhsiao(a)chromium.org> --- sound/soc/qcom/lpass-platform.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/soc/qcom/lpass-platform.c b/sound/soc/qcom/lpass-platform.c index b41ab7a321ae..ef5cb40b2d9b 100644 --- a/sound/soc/qcom/lpass-platform.c +++ b/sound/soc/qcom/lpass-platform.c @@ -1181,7 +1181,7 @@ static int lpass_platform_pcm_new(struct snd_soc_component *component, if (is_cdc_dma_port(dai_id)) return lpass_platform_prealloc_cdc_dma_buffer(component, pcm, dai_id); - return snd_pcm_set_fixed_buffer_all(pcm, SNDRV_DMA_TYPE_DEV, + return snd_pcm_set_fixed_buffer_all(pcm, SNDRV_DMA_TYPE_NONCOHERENT, component->dev, size); } -- 2.39.0.rc0.267.gcb52ba06e7-goog

The order of codec DAI phandles is reversed - first comes HDMI (always present) and then codec (physically not present on Odroid XU4).

[PATCH 1/3] ASoC: codecs: constify static sdw_slave_ops struct
by Krzysztof Kozlowski 26 Jan '23

26 Jan '23

The struct sdw_slave_ops is not modified and sdw_driver takes pointer to const, so make it a const for code safety.
