From 9cc63f8bcd560c760d0b12e15bba8f81c86237cf Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Fri, 14 Aug 2026 15:43:51 -0700 Subject: Merge branches 'expcb.2026.07.24a', 'misc.2026.07.30a', 'rcu-tasks.2026.07.30a', 'srcu.2026.08.11a' and 'torture.2026.08.14a' into HEAD Changes: Make expedited grace periods expedite normal RCU callbacks Miscellaneous fixes: * Improve diagnostic output with character task states. * Mark accesses to inform KCSAN of concurrency design. * Move from kmalloc() to kmalloc_obj(). * Documentation updates. * Improve handling of RCU deferred quiescent states. * Clean up unused function arguments and structure fields. * Reduce show_rcu_gp_kthreads() stack space. Tasks RCU updates: * Clean up after SRCU re-implementation of Tasks Trace RCU. * Mark accesses to inform KCSAN of concurrency design. * Add ->lazy_timer status to diagnostic output. * Remove an unnecessary memory barrier. * Fix a data race, courtesy of KCSAN. * Documentation updates. * Convert cond_resched_tasks_rcu_qs() from macro to static inline function. SRCU updates: * Add Rust helpers for SRCU. * Avoid losing queued work at cleanup_srcu_struct() time. Torture-test updates: * Preparation work for immediate RCU priority deboosting. * Test RCU readers from real interrupt handlers (as opposed to softirq). * Simplify code through use of cpumask_next_wrap(). * Improve diagnostic output with character task states. * Add rcutorture.nwriters parameter to allow lightweight stall testing, and rcutorture.stall_only to make doing so easier. * Test an RCU Tasks Trace grace period implying an RCU grace period. * Make RCU Tasks Trace torturing track reader batches. * Fix a data race, courtesy of KCSAN. * Plug a shuffle_tmp_mask memory leak on kthread spawn failure. --- sound/soc/sof/sof-client.h | 79 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 79 insertions(+) create mode 100644 sound/soc/sof/sof-client.h (limited to 'sound/soc/sof/sof-client.h') diff --git a/sound/soc/sof/sof-client.h b/sound/soc/sof/sof-client.h new file mode 100644 index 000000000..3b02506c0 --- /dev/null +++ b/sound/soc/sof/sof-client.h @@ -0,0 +1,79 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ + +#ifndef __SOC_SOF_CLIENT_H +#define __SOC_SOF_CLIENT_H + +#include +#include +#include +#include + +struct sof_ipc_fw_version; +struct sof_ipc_cmd_hdr; +struct snd_sof_dev; +struct dentry; + +struct sof_ipc4_fw_module; + +/** + * struct sof_client_dev - SOF client device + * @auxdev: auxiliary device + * @data: device specific data + */ +struct sof_client_dev { + struct auxiliary_device auxdev; + void *data; +}; + +#define auxiliary_dev_to_sof_client_dev(auxiliary_dev) \ + container_of(auxiliary_dev, struct sof_client_dev, auxdev) + +#define dev_to_sof_client_dev(dev) \ + container_of(to_auxiliary_dev(dev), struct sof_client_dev, auxdev) + +int sof_client_ipc_tx_message(struct sof_client_dev *cdev, void *ipc_msg, + void *reply_data, size_t reply_bytes); +static inline int sof_client_ipc_tx_message_no_reply(struct sof_client_dev *cdev, void *ipc_msg) +{ + return sof_client_ipc_tx_message(cdev, ipc_msg, NULL, 0); +} +int sof_client_ipc_set_get_data(struct sof_client_dev *cdev, void *ipc_msg, + bool set); + +struct sof_ipc4_fw_module *sof_client_ipc4_find_module(struct sof_client_dev *c, const guid_t *u); +struct snd_sof_widget *sof_client_ipc4_find_swidget_by_id(struct sof_client_dev *cdev, + u32 module_id, int instance_id); + +struct dentry *sof_client_get_debugfs_root(struct sof_client_dev *cdev); +struct device *sof_client_get_dma_dev(struct sof_client_dev *cdev); +const struct sof_ipc_fw_version *sof_client_get_fw_version(struct sof_client_dev *cdev); +size_t sof_client_get_ipc_max_payload_size(struct sof_client_dev *cdev); +enum sof_ipc_type sof_client_get_ipc_type(struct sof_client_dev *cdev); + +/* DSP/firmware boot request */ +int sof_client_boot_dsp(struct sof_client_dev *cdev); + +/* module refcount management of SOF core */ +int sof_client_core_module_get(struct sof_client_dev *cdev); +void sof_client_core_module_put(struct sof_client_dev *cdev); + +/* IPC notification */ +typedef void (*sof_client_event_callback)(struct sof_client_dev *cdev, void *msg_buf); + +int sof_client_register_ipc_rx_handler(struct sof_client_dev *cdev, + u32 ipc_msg_type, + sof_client_event_callback callback); +void sof_client_unregister_ipc_rx_handler(struct sof_client_dev *cdev, + u32 ipc_msg_type); + +/* DSP state notification and query */ +typedef void (*sof_client_fw_state_callback)(struct sof_client_dev *cdev, + enum sof_fw_state state); + +int sof_client_register_fw_state_handler(struct sof_client_dev *cdev, + sof_client_fw_state_callback callback); +void sof_client_unregister_fw_state_handler(struct sof_client_dev *cdev); +enum sof_fw_state sof_client_get_fw_state(struct sof_client_dev *cdev); +int sof_client_ipc_rx_message(struct sof_client_dev *cdev, void *ipc_msg, void *msg_buf); + +#endif /* __SOC_SOF_CLIENT_H */ -- cgit v1.3.1
