ASoC: SOF: fix 32 signed bit overflow

2022-03-07T13:12:52+00:00

Shifting in a signed 32bit container past the signed bit is technically undefined behaviour. Fix by using unsigned types. Found via cppcheck.

ASoC: SOF: trace: Add runtime trace filtering mechanism

2020-12-07T14:22:05+00:00

The "filter" debugfs file defines the log levels used by the firmware and reported by sof-logger. The file contains the formatted entry list, where each entry follows the following syntax in plain text: log_level uuid_id pipe_id comp_id; This file may be updated by userspace applications such sof-logger, or directly by the user during debugging process. An unused (wildcard) pipe_id or comp_id value should be set to -1, uuid_id is hexadecimal value, so when unused then should be set to 0. When the file is modified, an IPC command is sent to FW with new trace levels for selected components in filter elements list.

ASoC: SOF: IPC: fix implicit type overflow

2020-11-20T16:42:14+00:00

Implicit values may have a length of 15bits (s16) so we need to declare the proper size so we don't get undefined behaviour. This appears to be arch and compiler dependent. This commit is to keep the headers aligned between the firmware and kernel. UBSan discovered this bug in the firmware.

Add all required types and methods to support each and every request that driver could sent to firmware. Probe is one of SOF firmware features which allows for data extraction and injection directly from or to DMA stream. Exposes eight IPCs: - addition and removal of injection DMAs - addition and removal of probe points - info retrieval of injection DMAs and probe points - probe initialization and cleanup Signed-off-by: Cezary Rojewski Acked-by: Pierre-Louis Bossart Link: https://lore.kernel.org/r/20200218143924.10565-5-cezary.rojewski@intel.com Signed-off-by: Mark Brown
