[Sound-open-firmware] [PATCH] SRC: Use a multi-channel FIR core to optimize speed plus other cleanup
by Seppo Ingalsuo 19 Oct '17

19 Oct '17

This patch changes the sample rate conversion processing to use a single multi-channel filter instead of per channel called mono filter instances. The filter output is now rounded with 1/2 LSB add. The polyphase filter input input block sizes are multiplied in SRC initialization to reach near to or exacly the period length to reduce polyphase filter call overhead. The polyphase filter is now called via function pointer for more flexibility with audio data formats. Currently S32_LE and S24_4LE are supported. Code cleanup includes removal of redundant variables and some debug print code.

[Sound-open-firmware] [PATCH] trace: dma: Add atomic and nowait DMA tracing support.
by Liam Girdwood 19 Oct '17

19 Oct '17

Add support for DMA trace to run in atomic and IRQ contexts. Currently DMA trace would sleep between DMA copies and enter atomic state when inserting new tarce data into the trace buffer. This patch adds new DMA _nowait() APIs that dont sleep and _atomic() APIs for trace logging that can be safely called in atomic context.

The 1.0-dev branch and sof-v4.13 kernel will probably be better for Edison than the stable 0.95 branch atm (mainly due to driver updates), but 1.0-dev is still has a few issues prior to doing an rc1 tag.

[Sound-open-firmware] [PATCH] dma copy: trace: Fix locking with DMA trace and refactor API usage.
by Liam Girdwood 15 Oct '17

15 Oct '17

Fix locking in DMA trace. Also run the DMA trace as delayed work so we dont block callers. Refactor API so that DMAC and channel are pre-allocated.

[Sound-open-firmware] [PATCH 2/2] Forward trace event to DMA buffer.
by yan.wang＠linux.intel.com 13 Oct '17

13 Oct '17

From: Yan Wang <yan.wang(a)linux.intel.com> 1. Ignore DMA trace event when forwarding for avoiding dead lock because DMA tracing uses DMA API to copy trace event. 2. Add _trace_error() API to send error event by mail box at the same time too when copying error event by DMA.
