[Sound-open-firmware] [PATCH] Volume: Remove channels mapping via channel map array from volume control
by Seppo Ingalsuo 15 Nov '17

15 Nov '17

This patch removes the channel map table lookup from all volume control since it is not used by the SOF 1.0 driver. Instead of enum channel descriptors the channels are addressed with indices in 0..<number of channels -1> range.

[Sound-open-firmware] [PATCH] intel-ipc: fix host ring buffer size not page aligned issue
by Keyon Jie 15 Nov '17

15 Nov '17

The host ring buffer size may be not page aligned, but the last page was ulitlized by host component wrongly, which may introduce beating noise. Here change to correct size for the last element, which will fix the issue.

[Sound-open-firmware] [PATCH v2 4/4] Fix DMA host offset calculation and wrapper condition checking.
by yan.wang＠linux.intel.com 10 Nov '17

From: Yan Wang <yan.wang(a)linux.intel.com> 1. "size" should not be considered twice. 2. Change host_offset to uint32_t type. 3. size = min(hsize, lsize), so it is unncessary to check ">" for wrap local and host buffer.
