[PATCH][next] soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size()
by Gustavo A. R. Silva 16 Oct '23

16 Oct '23

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). While there, use struct_size() helper, instead of the open-coded version, to calculate the size for the allocation of the whole flexible structure, including of course, the flexible-array member. This code was found with the help of Coccinelle, and audited and fixed manually. Signed-off-by: Gustavo A. R.

[PATCH v3 1/2] ASoC: dt-bindings: sound-card-common: List DAPM endpoints ignoring system suspend
by Chancel Liu 16 Oct '23

16 Oct '23

Add a property to list DAPM endpoints which mark paths between these endpoints should not be disabled when system enters in suspend state. LPA means low power audio case. For example on asymmetric multiprocessor, there are Cortex-A core and Cortex-M core, Linux is running on Cortex-A core, RTOS or other OS is running on Cortex-M core. The audio hardware devices can be controlled by Cortex-M. LPA can be explained as a mechanism that Cortex-A allocates a large buffer and fill audio data, then Cortex-A can enter into suspend for the purpose of power saving. Cortex-M continues to play the sound during suspend phase of Cortex-A. LPA requires some audio paths still enabled when Cortex-A enters into suspend.

[PATCH] soundwire: bus: improve error handling for clock stop prepare/deprepare
by Bard Liao 16 Oct '23

16 Oct '23

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> The same logic is used for clock stop prepare and deprepare, and having different logs for the two steps helps identify problems. In addition, when the "NotFinished" bit remains set, the error handling is not quite right: a) for the clock stop prepare, the error is handled at the caller level, and the error is ignored: there's no good reason to prevent the pm_runtime suspend from happening. Throwing an error that is later ignored is confusing. b) for the clock stop deprepare, the error is ignored in bus.c and a dev_warn() log shown. Throwing an error is also alarming users for no good reason. For both cases, demoting the error to dev_dbg() makes more sense.
