[PATCH 00/14] ARM: remove unused davinci board & drivers
by Arnd Bergmann 14 Nov '22

14 Nov '22

From: Arnd Bergmann <arnd(a)arndb.de> As part of removing all board files that were previously marked as unused, I looked through the davinci platform and recursively removed everything that has now become unused. In particular, this is for all dm3xx support, in addition to the dm64xx support removed previously. The remaining support is now for da8xx using devicetree only, which means a lot of the da8xx specific device support can also go away. As with the previous series, I can keep patches together in the soc tree, or subsystem maintainers can pick them up individually through their subsystems, whichever they prefer.

The fallback path was introduced for the case where > there is no IOMMU and noncontiguous allocation fails from the > beginning. follow-up to this problem. It turns out there was additional problem with dma_alloc_noncontiguous that led to ENOMEM much more frequently than in the past. This required following: - your rework in 5.16 to sound/core/memalloc.c for x86 DMA SG - IOMMU/DMAR enabled for the device - CONFIG_DMA_REMAP=n (default 'n' on most/all x86 systems before 5.18) ... with above combination, iommu_dma_ops in drivers/iommu/dma-iommu.c were not defined for noncontiguous alloc/free, so the dma_alloc_noncontiguous() in the end went back to plain dma_common_alloc_pages() (single contiguous alloc), which would fail very easily when system was in low-mem condition. In 5.18, this patch was added commit f5ff79fddf0efecca538046b5cc20fb3ded2ec4f Author: Christoph Hellwig <hch(a)lst.de> Date: Sat Feb 26 16:40:21 2022 +0100 dma-mapping: remove CONFIG_DMA_REMAP ... and this basicly fixes the issue again, even when IOMMU is enabled.

[PATCH] ALSA: memalloc: Allocate more contiguous pages for fallback case
by Takashi Iwai 14 Nov '22

14 Nov '22

Currently the fallback SG allocation tries to allocate each single page, and this tends to result in the reverse order of memory addresses when large space is available at boot, as the kernel takes a free page from the top to the bottom in the zone. The end result looks as if non-contiguous (although it actually is). What's worth is that it leads to an overflow of BDL entries for HD-audio. For avoiding such a problem, this patch modifies the allocation code slightly; now it tries to allocate the larger contiguous chunks as much as possible, then reduces to the smaller chunks only if the allocation failed -- a similar strategy as the existing snd_dma_alloc_pages_fallback() function. Along with the trick, drop the unused address array from snd_dma_sg_fallback object. It was needed in the past when dma_alloc_coherent() was used, but with the standard page allocator, it became superfluous and never referred.

[PATCH v2 0/2] ASoC: Intel: avs: DSP recovery and resume fixes
by Cezary Rojewski 14 Nov '22

14 Nov '22

Two fixes that are result of the recent discussions [1][2]. First adds missing locking around snd_pcm_stop() while the second fix sets substream state to DISCONNECTED if any suspend/resume related operation fails so that userspace has means to be aware that something went wrong during said operation. Changes in v2: - __snd_pcm_set_state() replaced direct assignments of PCM state [1]: https://lore.kernel.org/alsa-devel/73e6425f-8e51-e26f-ad83-ccc5df517a43@int… [2]: https://lore.kernel.org/alsa-devel/20221104131244.3920179-1-cezary.rojewski… Cezary Rojewski (2): ASoC: Intel: avs: Lock substream before snd_pcm_stop() ASoC: Intel: avs: Disconnect substream if suspend or resume fails sound/soc/intel/avs/ipc.c | 2 ++ sound/soc/intel/avs/pcm.c | 10 ++++++++-- 2 files changed, 10 insertions(+), 2 deletions(-) -- 2.25.1
