ALSA: core: Use ktime_get_ts()

2014-06-12T10:58:16+00:00

do_posix_clock_monotonic_gettime() is a leftover from the initial
posix timer implementation which maps to ktime_get_ts().

ALSA: timer: Use standard printk helpers

2014-02-14T07:14:17+00:00

Use the standard pr_xxx() helpers instead of home-baked snd_print*().

ALSA: Replace with IS_ENABLED()

2014-02-10T10:42:00+00:00

Replace the lengthy #if defined(XXX) || defined(XXX_MODULE) with the
new IS_ENABLED() macro.

The patch still doesn't cover all ifdefs.  For example, the dependency
on CONFIG_GAMEPORT is still open-coded because this also has an extra
dependency on MODULE.  Similarly, an open-coded ifdef in pcm_oss.c and
some sequencer-related stuff are left untouched.

device.h: cleanup users outside of linux/include (C files)

2012-03-11T18:27:37+00:00

For files that are actively using linux/device.h, make sure
that they call it out.  This will allow us to clean up some
of the implicit uses of linux/device.h within include/*
without introducing build regressions.

Yes, this was created by "cheating" -- i.e. the headers were
cleaned up, and then the fallout was found and fixed, and then
the two commits were reordered.  This ensures we don't introduce
build regressions into the git history.

sound: fix drivers needing module.h not moduleparam.h

2011-10-31T23:31:19+00:00

The implicit presence of module.h lured several users into
incorrectly thinking that they only needed/used modparam.h
but once we clean up the module.h presence, these will show
up as build failures, so fix 'em now.

ALSA: timer - Add NULL-check for invalid slave timer

ALSA: timer - Fix Oops at closing slave timer

2011-08-08T10:24:46+00:00

A slave-timer instance has no timer reference, and this results in
NULL-dereference at stopping the timer, typically called at closing
the device.

ALSA: support module on-demand loading for seq and timer

2010-11-24T04:53:25+00:00

If CONFIG_SND_DYNAMIC_MINORS is used, assign /dev/snd/seq and
/dev/snd/timer the usual static minors, and export specific
module aliases to generate udev module on-demand loading
instructions:

  $ cat /lib/modules/2.6.33.4-smp/modules.devname
  # Device nodes to trigger on-demand module loading.
  microcode cpu/microcode c10:184
  fuse fuse c10:229
  ppp_generic ppp c108:0
  tun net/tun c10:200
  uinput uinput c10:223
  dm_mod mapper/control c10:236
  snd_timer snd/timer c116:33
  snd_seq snd/seq c116:1

The last two lines instruct udev to create device nodes, even
when the modules are not loaded at that time.

As soon as userspace accesses any of these nodes, the in-kernel
module-loader will load the module, and the device can be used.

The header file minor calculation needed to be simplified to
make __stringify() (supports only two indirections) in
the MODULE_ALIAS macro work.

This is part of systemd's effort to get rid of unconditional
module load instructions and needless init scripts.

ALSA: timer: automatically load the high-resolution timer

2010-11-22T07:14:31+00:00

Increase the default timer limit so that snd-hrtimer.ko can be
automatically loaded when needed, e.g., when used as the default
sequencer timer.  This replaces the check for the obsolete
CONFIG_SND_HPET.
