[PATCH v2] ASoC: amd: Fix reference to PCM buffer address
by Takashi Iwai 02 Aug '21

02 Aug '21

PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The driver needs to refer to substream->runtime->dma_addr instead for the buffer address.

[PATCH 0/6] ASoC: Intel: bytcr_rt5640: Fix HP ElitePad 1000 G2 audio routing
by Hans de Goede 02 Aug '21

02 Aug '21

The HP Elitepad 1000 G2 has 2 headset jacks: 1. on the dock which uses the output of the codecs built-in HP-amp + the standard IN2 input which is always used with the headset-jack. 2. on the tablet itself, this uses the line-out of the codec, combined with an external HP-amp + IN1 for the headset-mic. This series adds support for this, resolving: https://bugzilla.kernel.org/show_bug.cgi?id=213415 Note this series does not add jack-detect support. I plan to add that with a follow-up series when I can make some time to implement that.

[PATCH] soundwire: cadence: add paranoid check on self-clearing bits
by Bard Liao 02 Aug '21

02 Aug '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> The Cadence IP exposes a small number of self-clearing bits in the MCP_CONTROL and MCP_CONFIG_UPDATE registers. We currently do not check that those bits are indeed cleared, e.g. during resume operations. That could lead to resuming peripheral devices too early. In addition, if we happen to read these registers, update one of the fields and write the register back, we may be writing stale data that might have been cleared in hardware. These sort of race conditions could lead to e.g. doing a hw_reset twice or stopping a clock that just restarted. There is no clear way of avoiding these potential race conditions other than making sure that these registers fields are cleared before any read-modify-write sequence. If we detect this sort of errors, we only log them since there is no clear recovery possible. The only way out is likely to restart the IP with a suspend/resume cycle. Note that the checks are performed before updating the registers, as well as after the Intel 'sync go' sequence in multi-link mode. That should cover both the start and end of suspend/resume hardware configurations. The Multi-Master mode gates the configuration updates until the 'sync go' signal is asserted, so we only check on init and after the end of the 'sync go' sequence. The duration of the usleep_range() was defined by the GSYNC frequency used in multi-master mode. With a 4kHz frequency, any configuration change might be deferred by up to 250us. Extending the range to 1000-1500us should guarantee that the configuration change is completed without any significant impact on the overall resume time.
