[Sound-open-firmware] [PATCH] dai: cache: Make sure we only writeback the amount copied
by Liam Girdwood 21 Sep '17

21 Sep '17

The DAI IRQ hanlder was always writing back full period size even when less data was copied. Only writeback the amount of data copied.

[Sound-open-firmware] [PATCH] timer: Add support for 64 bit timers.
by Liam Girdwood 20 Sep '17

20 Sep '17

This patch changes the time and timeouts used by timers from a uint32_t to a uint64_t. This means clocks can run for years before overflow. This patch also provides a virtual high 32 bits for HW that only has 32bit timer support. i.e. the high 32 is incremented at every HW timer overflow. Finally the patch updates all timer users to use uint64_t timeouts.

[Sound-open-firmware] [PATCH 3/4] Add the implementation for DMA tracing.
by yan.wang＠linux.intel.com 18 Sep '17

18 Sep '17

From: Yan Wang <yan.wang(a)linux.intel.com> 1. Initialize the data structure. a) Create local DMA buffer for saving trace data. b) Initialize the tracing work handler for syatem work queue. 2. Implement local circle buffer. a) When the local buffer is full, empty it and reset reading/writing pointer. 3. Save the host buffer PHY addr which is parsed from IPC message. After this config, start trace work in work queue. 4. Provide dtrace_event() for recroding trace string into local buffer. 5. Add rstrlen() utility function for getting the trace string length because DSP side hasn't strlen(). 6. Enbale trace DMA copying once every 500ms or some special cases. a) Schedule the tracing sending work once every 500ms. b) If the local buffer is half full, call trace sending immediately. c) When the wrting pointer will arrive iat the end of local buffer, call trace sending immediately. 7. Use dma_copy_to_host() function to do trace sending.
