ALSA: info: Make snd_info_entry_ops as const

2020-01-03T08:24:18+00:00

The reference to snd_info_entry_ops is rather read-only, so declare it as a const pointer. This allows a bit more optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-29-tiwai@suse.de Signed-off-by: Takashi Iwai

ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS

2015-05-27T19:25:19+00:00

We may disable proc fs only for sound part, to reduce ALSA memory footprint. So add CONFIG_SND_PROC_FS and replace the old CONFIG_PROC_FSs in alsa code. With sound proc fs disabled, we can save about 9KB memory size on X86_64 platform. Signed-off-by: Jie Yang Reviewed-by: Mark Brown Signed-off-by: Takashi Iwai

ALSA: core: Clean up OSS proc file management

2015-04-24T15:31:08+00:00

A few minor cleanups: - Move the call of snd_info_minor_register() into snd_info_init() so that we can call all proc-related stuff in a shot - Add missing __init prefix to snd_info_minor_register() - Return an error properly from snd_oss_info_register() - Drop snd_info_minor_unregister() that is superfluous now Acked-by: Jaroslav Kysela Signed-off-by: Takashi Iwai

ALSA: core: Remove child proc file elements recursively

2015-04-24T15:27:57+00:00

This patch changes the way to manage the resource release of proc files: namely, let snd_info_free_entry() freeing the whole children. This makes it us possible to drop the snd_device_*() management. Then snd_card_proc_new() becomes merely a wrapper to snd_info_create_card_entry(). Together with this change, now you need to call snd_info_free_entry() for a proc entry created via snd_card_proc_new(), while it was freed via snd_device_free() beforehand.

ALSA: core: Use seq_file for text proc file reads

2015-04-23T15:11:02+00:00

seq_file is _the_ standard interface for simple text proc files. Though, we still need to support the binary proc files and the text file write, and also we need to manage the device disconnection gracefully. Thus this patch just replaces the text file read code with seq_file while keeping the rest intact. snd_iprintf() helper function is now a macro to expand itself to seq_printf() to be compatible with the existing code. The seq_file object is stored to the unused entry->rbuffer->buffer pointer. When the output size is expected to be large (greater than PAGE_SIZE), the driver should set entry->size field beforehand. Then the given size will be preallocated and the multiple show calls can be avoided. Acked-by: Jaroslav Kysela Signed-off-by: Takashi Iwai
