ALSA: serial-generic: remove shared static buffer

2025-11-24T09:29:38+00:00

[ Upstream commit 84973249011fda3ff292f83439a062fec81ef982 ] If multiple instances of this driver are instantiated and try to send concurrently then the single static buffer snd_serial_generic_tx_work() will cause corruption in the data output. Move the buffer into the per-instance driver data to avoid this. Signed-off-by: John Keeping Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin

ALSA: pcmtest: stop timer before buffer is released

2024-01-20T10:51:42+00:00

[ Upstream commit eb99b1b72a424a79f56c972e0fd7ad01fe93a008 ] Stop timer in the 'trigger' and 'sync_stop' callbacks since we want the timer to be stopped before the DMA buffer is released. Otherwise, it could trigger a kernel panic in some circumstances, for instance when the DMA buffer is already released but the timer callback is still running.

Merge tag 'asoc-v6.6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2023-08-28T14:13:03+00:00

ASoC: Updates for v6.6 The rest of the updates for v6.6, some of the highlights include: - A big API cleanup from Morimoto-san, rationalising the places we put functions. - Lots of work on the SOF framework, AMD and Intel drivers, including a lot of cleanup and new device support. - Standardisation of the presentation of jacks from drivers. - Provision of some generic sound card DT properties. - Conversion oof more drivers to the maple tree register cache. - New drivers for AMD Van Gogh, AWInic AW88261, Cirrus Logic cs42l43, various Intel platforms, Mediatek MT7986, RealTek RT1017 and StarFive JH7110.

ALSA: pcmtest: Add support for pcm pausing

2023-08-24T07:58:22+00:00

Add pause push/release support to the virtual PCM test driver. Add 'suspend' boolean field to the pcmtst_buf_iter structure, so we can pause the timer without shutting it down. Update the trigger callback handler correspondingly. Extract buffer initialization to the 'reset_buf_iterator' function since it is used in multiple places now.

ALSA: pcmtest: Update comment about PCM copy ops

2023-08-18T10:18:26+00:00

Just an update of a comment mentioning the old PCM callbacks to correct to the new PCM copy ops. Link: https://lore.kernel.org/r/20230815190136.8987-17-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: dummy: Convert to generic PCM copy ops

2023-08-18T10:18:17+00:00

This patch converts the dummy driver code to use the new unified PCM copy callback. As dummy driver doesn't do anything in the callback, it's just a simple replacement. Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20230815190136.8987-5-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: Make SND_PCMTEST depend on DEBUG_FS

2023-08-18T07:10:22+00:00

Since pcmtest is a test module that manipulates or gets notification via debugfs, without DEBUG_FS it can not work fine. So make SND_PCMTEST depend on DEBUG_FS.

ALSA: Remove redundant of_match_ptr()

2023-08-13T18:37:47+00:00

The driver depends on CONFIG_OF, it is not necessary to use of_match_ptr() here. Signed-off-by: Ruan Jinjie

ALSA: pcmtest: Remove redundant definitions

2023-08-08T12:44:43+00:00

Remove redundant definitions of DEVNAME and CARD_NAME, as they're not useful. The former is not used anywhere, and the latter is used only in module parameters descriptions.

ALSA: pcmtest: Move buffer iterator initialization to prepare callback

2023-08-08T12:44:42+00:00

Trigger callback is not the best place for buffer iterator initialization, so move it out to the prepare callback, where it have to be. Minor enhancement: remove blank line.
