ALSA: firewire: fireface: Use safer strscpy() instead of strcpy()

Use a safer function strscpy() instead of strcpy() for copying to arrays. Only idiomatic code replacement, and no functional changes. Signed-off-by: Takashi Iwai Reviewed-by: Takashi Sakamoto Link: https://patch.msgid.link/20250710100727.22653-17-tiwai@suse.de

ALSA: firewire: use nonatomic PCM operation

2024-09-04T12:51:54+00:00

In the former commits, the callback of isochronous context runs on usual work process. In the case, ALSA PCM device has a flag, nonatomic, to acquire mutex lock instead of spin lock for PCM substream group. This commit uses the flag. It has an advantage in the case that ALSA PCM application uses the large size of intermediate buffer, since it takes too long time even in tasklet softIRQ to process many of isochronous packets, then result in the delay of system event due to disabled IRQ so long. It is avertible to switch to nonatomic operation.

ALSA: firewire: Use -y instead of -objs in Makefile

2024-05-08T16:18:03+00:00

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.

ALSA: firewire: Fix -Wformat-truncation warning for MIDI stream names

2023-09-15T11:22:06+00:00

The compile warnings at filling MIDI stream name strings are all false-positive; the number of streams can't go so high. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.

ALSA: fireface: add field for the number of messages copied to user space

2023-02-04T08:35:17+00:00

Current structure includes no field to express the number of messages copied to user space, thus user space application needs to information out of the structure to parse the content of structure. This commit adds a field to express the number of messages copied to user space since It is more preferable to use self-contained structure. Kees Cook proposed an idea of annotation for bound of flexible arrays in his future improvement for flexible-length array in kernel. The additional field for message count is suitable to the idea as well.
