* ALSA: portman2x4: Convert to platform remove callback returning voidUwe Kleine-König2023-03-201-4/+2
| | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

* ALSA: pcsp: Make hrtimer forwarding more robustThomas Gleixner2021-09-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The hrtimer callback pcsp_do_timer() prepares rearming of the timer with hrtimer_forward(). hrtimer_forward() is intended to provide a mechanism to forward the expiry time of the hrtimer by a multiple of the period argument so that the expiry time greater than the time provided in the 'now' argument. pcsp_do_timer() invokes hrtimer_forward() with the current timer expiry time as 'now' argument. That's providing a periodic timer expiry, but is not really robust when the timer callback is delayed so that the resulting new expiry time is already in the past which causes the callback to be invoked immediately again. If the timer is delayed then the back to back invocation is not really making it better than skipping the missed periods. Sound is distorted in any case. Use hrtimer_forward_now() which ensures that the next expiry is in the future. This prevents hogging the CPU in the timer expiry code and allows later on to remove hrtimer_forward() from the public interfaces.

A new control layer registration is introduced which allows to run additional operations on top of the elementary ALSA sound controls. A new control access group (three bits in the access flags) was introduced to carry the LED group information for the sound controls. The low-level sound drivers can just mark those controls using this access group. This information is not exported to the user space, but user space can manage the LED sound control associations through sysfs (last patch) per Mark's request. It makes things fully configurable in the kernel and user space (UCM). The actual state ('route') evaluation is really easy (the minimal value check for all channels / controls / cards). If there's more complicated logic for a given hardware, the card driver may eventually export a new read-only sound control for the LED group and do the logic itself. The new LED trigger control code is completely separated and possibly optional (there's no symbol dependency). The full code separation allows eventually to move this LED trigger control to the user space in future. Actually it replaces the already present functionality in the kernel space (HDA drivers) and allows a quick adoption for the recent hardware (ASoC codecs including SoundWire). snd_ctl_led 24576 0 The sound driver implementation is really easy: 1) call snd_ctl_led_request() when control LED layer should be automatically activated / it calls module_request("snd-ctl-led") on demand / 2) mark all related kcontrols with SNDRV_CTL_ELEM_ACCESS_SPK_LED or SNDRV_CTL_ELEM_ACCESS_MIC_LED Link: https://lore.kernel.org/r/20210317172945.842280-1-perex@perex.cz Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: aloop: Constify ops structsRikard Falkeborn2020-11-211-3/+3
| | | | | | | | | | | The only usage of the ops field in the loopback_cable struct is to call its members, the field it self is never changed. Make it a pointer to const. This allows us to constify two static loopback_ops structs to allow the compiler to put them in read-only memory.

* ALSA: aloop: Replace tasklet with workTakashi Iwai2020-09-091-12/+11
| | | | | | | | | | | | | The tasklet is an old API that should be deprecated, usually can be converted to another decent API. In aloop driver, a tasklet is still used for offloading the timer event task. It can be achieved gracefully with a work queued, too. This patch replaces the tasklet usage in aloop driver with a simple work. Link: https://lore.kernel.org/r/20200903104131.21097-6-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: pcsp: Replace tasklet with workTakashi Iwai2020-09-091-7/+5
| | | | | | | | | | | | | | | | | The tasklet is an old API that should be deprecated, usually can be converted to another decent API. This patch replaces the usage of tasklet in pcsp driver with a simple work. In pcsp driver, a global tasklet is used for offloading the period-elapse handling in the hrtimer callback (introduced in commit 96c7d478efad "ALSA: pcsp - Fix locking messes in snd-pcsp"). It can be achieved gracefully with a work queued in the high-prio system workqueue. This also changes tasklet_kill() with cancel_work_sync() in the sync_stop callback, which is anyway better to assure canceling the pending tasks.
