From 4352b8aee98005853aa63f57d6377282de17a33f Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 23 Aug 2026 13:28:57 -0700 Subject: Merge tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux Pull I3C updates from Alexandre Belloni: "A new driver this cycle, for the AMD AXI I3C controller. There are also new features such as IBI wakeup support, SETAASA device discovery and ACPI support for the the DAA methods, meaning we can now communicate with the SPD devices on DDR5 modules. New driver: - AMD AXI I3C master controller Subsystem: - I3C Common Command Code (CCC) handling improvements, especially around GET CCCs - SETAASA device discovery support - ACPI support for all existing DAA methods like SETDASA, SETNEWDA as well as I2C devices on I3C bus - IBI-based wakeup support Drivers: - dw: SETAASA support - mipi-i3c-hci: advertise IBI wakeup capability, AMD_PT I3C controller support, PIO queue management support for HCI v1.2 - renesas: improve suspend to RAM support, add runtime PM support" * tag 'i3c/for-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/i3c/linux: (70 commits) i3c: dw: reduce do_daa time if there's no client i3c: mipi-i3c-hci: Add support for AMD_PT I3C controller i3c: mipi-i3c-hci: Add PIO queue management support for HCI v1.2 i3c: mipi-i3c-hci: Fix missing STAT_IBI_STATUS_THLD in PIO mode i3c: dw: rename "pclk" to "apb" to match dt-binding i3c: dw: make struct dw_i3c_cmd smaller i3c: dw: use COMMAND_PORT_TRANSFER_ARG instead of hardcoding i3c: renesas: Don't register devices when ENTDAA times out i3c: master: dw-i3c-master: fix OD timing for first broadcast i3c: mipi-i3c-hci: Advertise IBI wakeup capability i3c: mipi-i3c-hci: Factor out i3c_hci_sysdev() i3c: mipi-i3c-hci-pci: Propagate I3C wakeup requirements to PCI i3c: master: Reject IBI requests from non-IBI-capable devices i3c: master: Add helper to query bus wakeup requirements i3c: master: Report wakeup events for IBIs i3c: master: Support IBI-based wakeup capability i3c: master: Fix potential UAF in i3c_device_match() i3c: master: Fix potential UAF in i3c_device_uevent() i3c: Make dev->desc locking assumptions explicit i3c: master: Fix use-after-free of master->this ... --- include/sound/seq_oss.h | 83 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 83 insertions(+) create mode 100644 include/sound/seq_oss.h (limited to 'include/sound/seq_oss.h') diff --git a/include/sound/seq_oss.h b/include/sound/seq_oss.h new file mode 100644 index 000000000..7bf10a0fa --- /dev/null +++ b/include/sound/seq_oss.h @@ -0,0 +1,83 @@ +/* SPDX-License-Identifier: GPL-2.0-or-later */ +#ifndef __SOUND_SEQ_OSS_H +#define __SOUND_SEQ_OSS_H + +/* + * OSS compatible sequencer driver + * + * Copyright (C) 1998,99 Takashi Iwai + */ + +#include +#include + +/* + * argument structure for synthesizer operations + */ +struct snd_seq_oss_arg { + /* given by OSS sequencer */ + int app_index; /* application unique index */ + int file_mode; /* file mode - see below */ + int seq_mode; /* sequencer mode - see below */ + + /* following must be initialized in open callback */ + struct snd_seq_addr addr; /* opened port address */ + void *private_data; /* private data for lowlevel drivers */ + + /* note-on event passing mode: initially given by OSS seq, + * but configurable by drivers - see below + */ + int event_passing; +}; + + +/* + * synthesizer operation callbacks + */ +struct snd_seq_oss_callback { + struct module *owner; + int (*open)(struct snd_seq_oss_arg *p, void *closure); + int (*close)(struct snd_seq_oss_arg *p); + int (*ioctl)(struct snd_seq_oss_arg *p, unsigned int cmd, unsigned long arg); + int (*load_patch)(struct snd_seq_oss_arg *p, int format, const char __user *buf, int offs, int count); + int (*reset)(struct snd_seq_oss_arg *p); + int (*raw_event)(struct snd_seq_oss_arg *p, unsigned char *data); +}; + +/* flag: file_mode */ +#define SNDRV_SEQ_OSS_FILE_ACMODE 3 +#define SNDRV_SEQ_OSS_FILE_READ 1 +#define SNDRV_SEQ_OSS_FILE_WRITE 2 +#define SNDRV_SEQ_OSS_FILE_NONBLOCK 4 + +/* flag: seq_mode */ +#define SNDRV_SEQ_OSS_MODE_SYNTH 0 +#define SNDRV_SEQ_OSS_MODE_MUSIC 1 + +/* flag: event_passing */ +#define SNDRV_SEQ_OSS_PROCESS_EVENTS 0 /* key == 255 is processed as velocity change */ +#define SNDRV_SEQ_OSS_PASS_EVENTS 1 /* pass all events to callback */ +#define SNDRV_SEQ_OSS_PROCESS_KEYPRESS 2 /* key >= 128 will be processed as key-pressure */ + +/* default control rate: fixed */ +#define SNDRV_SEQ_OSS_CTRLRATE 100 + +/* default max queue length: configurable by module option */ +#define SNDRV_SEQ_OSS_MAX_QLEN 1024 + + +/* + * data pointer to snd_seq_register_device + */ +struct snd_seq_oss_reg { + int type; + int subtype; + int nvoices; + struct snd_seq_oss_callback oper; + void *private_data; +}; + +/* device id */ +#define SNDRV_SEQ_DEV_ID_OSS "seq-oss" + +#endif /* __SOUND_SEQ_OSS_H */ -- cgit v1.3.1
