ALSA: seq: Simplify snd_seq_kernel_client_enqueue() helper

2019-04-12T10:51:22Z

We have two helpers for queuing a sequencer event from the kernel client, and both are used only from OSS sequencer layer without any hop and atomic set. Let's simplify and unify two helpers into one. No functional change, just a call pattern change. Signed-off-by: Takashi Iwai

ALSA: seq: Avoid invalid lockdep class warning

2017-11-06T19:25:31Z

The recent fix for adding rwsem nesting annotation was using the given "hop" argument as the lock subclass key. Although the idea itself works, it may trigger a kernel warning like: BUG: looking up invalid subclass: 8 .... since the lockdep has a smaller number of subclasses (8) than we currently allow for the hops there (10). The current definition is merely a sanity check for avoiding the too deep delivery paths, and the 8 hops are already enough. So, as a quick fix, just follow the max hops as same as the max lockdep subclasses.

ALSA: seq: Drop snd_seq_autoload_lock() and _unlock()

2015-02-12T13:42:31Z

The autoload lock became already superfluous due to the recent rework of autoload code. Let's drop them now. This allows us to simplify a few codes nicely. Signed-off-by: Takashi Iwai

ALSA: seq: increase the maximum number of queues

2015-01-26T12:57:29Z

Queues are used both for scheduling playback events and for assigning timestamps to recorded events, so it is easy to need quite a lot of them, especially on a multi-user system. Additionally, the actual queue objects are allocated dynamically, so it does not really make sense to have a low limit. Increase it to something still sane.

ALSA: seq: bind seq driver automatically

2014-10-18T18:25:12Z

Currently the sequencer module binding is performed independently from the card module itself. The reason behind it is to keep the sequencer stuff optional and allow the system running without it (e.g. for using PCM or rawmidi only). This works in most cases, but a remaining problem is that the binding isn't done automatically when a new driver module is probed. Typically this becomes visible when a hotplug driver like usb audio is used. This patch tries to address this and other potential issues. First, the seq-binder (seq_device.c) tries to load a missing driver module at creating a new device object. This is done asynchronously in a workq for avoiding the deadlock (modprobe call in module init path). This action, however, should be enabled only when the sequencer stuff was already initialized, i.e. snd-seq module was already loaded. For that, a new function, snd_seq_autoload_init() is introduced here; this clears the blocking of autoloading, and also tries to load all pending driver modules.
