[Sound-open-firmware] Reef, Minnowboard Max or Asus T100
by Chun-ta Lin 11 Dec '17

11 Dec '17

Hello SOF Gurus, This is Peter from ChromeOS@Google. I'm interested in the project and is trying to reproduce/ understanding from the main page <https://www.alsa-project.org/main/index.php/Firmware>. I noticed that in the instruction, the topic is reef w/ 4.8 kernel version. Since I'm quite a newbie in this area, wondering from a learning perspective, what would be recommended hardware for this purpose ? Will it be a bit more complicated to build / debug it with Reef (like kernel need to sign after build), or ASUS T100 (an Windows platform). Looking forward for reply, itsPeter

[Sound-open-firmware] [PATCH] Add support to replace stale stream/trace position updates.
by yan.wang＠linux.intel.com 23 Nov '17

23 Nov '17

From: Yan Wang <yan.wang(a)linux.intel.com> 1. Add "replace" parameter for ipc_queue_host_message() to indicate whether check duplicate message in host message queue. 2. Add msg_find() to search duplicate message. 3. If replace flag is true, search and replace duplicate message. 4. For the message of host offset of DMA trace, enable replace logic. It will avoid that the host message queue is full because there is too many IPC messages of host offset of DMA trace.

[Sound-open-firmware] [PATCH] scheduler: Allow tasks to be scheduled when DSP enters idle state
by Liam Girdwood 17 Nov '17

17 Nov '17

Add an API to allow tasks to be added to the scheduler task list but not run until the DSP enters an idle state. i.e. we schedule the task as normal but dont immediately call schedule() to schedule that task for execution and instead wait until schedule() is next called (at the end of some other work). This patch also calls schedule() before entering the idle state in the main processing loop.
