0d8ff0712b pcm: plug: add SND_PCM_FORMAT_{S, U}20 to linear_preferred_formats
This commit adds the recently added formats SND_PCM_FORMAT_{S,U}20 to
the linear_preferred_formats array in pcm_plug.
Let's give them lower priority than more standard S24 formats but a higher
priority than less typical 3-byte versions.

0c081ebbed pcm: linear, route: handle linear formats with 20-bit sample on 4 bytes
The previous patch has added 20-bit PCM formats SND_PCM_FORMAT_{S,U}20 to
alsa-lib.
We need to extend the linear format conversion code with handling of these
sample formats so they can also be utilized by applications that only
recognize the more typical ones like SND_PCM_FORMAT_S16.

Since the conversion arrays are indexed by a format bit width divided by 8
the easiest way to handle these formats is to treat them like they were
40-bit wide (the next free integer multiple of 8 bits).
This doesn't create a collision risk with a future format since there can't
really be a 40-bit sample format that occupies 4 bytes.

Make sure we use the getput conversion method for these formats since a
direct conversion from / to them is not supported.

d67e42c139 pcm: add and describe SND_PCM_FORMAT_{S, U}20
This patch adds and describes in various functions that query format
properties SND_PCM_FORMAT_{S,U}20 formats that were recently added to the
kernel as SNDRV_PCM_FORMAT_{S,U}20.

These formats are similar to existing 20-bit PCM formats
SND_PCM_FORMAT_{S,U}20_3, however they occupy 4 bytes instead of 3.

6d951ddf00 ctl: deprecate APIs of dimensional information
In ALSA control interface in asound.h, 'struct snd_ctl_elem_info' has
'dimen' member to deliver information for multi-dimensional array, however
there's no common way to handle the member. As a result, drivers can
force userspace applications to handle the information by inconsistent
ways.

This issue was reported by a commit 51db452df07b ('Revert "ALSA: echoaudio:
purge contradictions between dimension matrix members and total number of
members"') to Linux kernel. As a result of discussion at Linux
miniconference 2017, usage of 'dimen' member of 'struct snd_ctl_elem_info'
is going to be deprecated for future removal.

A removal of kernel interface can cause regression issues. However no ALSA
driver in kernel land except for 'echoaudio' series utilizes this feature.
Actually it's reasonable to assume that 'echomixer' program is an unique
consumer of the interface in user land and the removal rarely brings any
impact to user land.

This commit deprecates some APIs corresponding to the kernel interface. The
kernel interface is kept till Linux kernel v4.20 at least, but actual
timing of removal is not fixed yet. After that, these APIs may also be
removed at a reasonable timing.

996dd33b5f conf: HdmiLpeAudio: remove the "front" pcm definition
PulseAudio assumes that the "front" pcm device always refers to an
analog device, not HDMI. While that assumption is not really valid, the
reality is that without that assumption PulseAudio can't know whether
"front" and "hdmi" refer to a different or the same device.

The HDMI LPE driver doesn't allow audio streaming while the HDMI cable
is unplugged, so PulseAudio has to know when it's plugged in and when
it's not. If both "front" and "hdmi" devices exist, PulseAudio will
notice that HDMI is unplugged, but it doesn't know that "front" refers
to the same device, and PulseAudio will try to use the "front" device
with bad consequences. The kernel driver's refusal to stream any audio
makes PulseAudio enter an infinite loop and then the kernel kills
PulseAudio, because it consumes too much CPU time in a realtime thread.

While the looping in PulseAudio could probably be fixed, that wouldn't
change the fact that PulseAudio thinks that there is an analog device. I
believe it's best to avoid having the same device as both "front" and
"hdmi" in alsa-lib.

I removed also the surround configuration includes. I don't think they
had any effect anyway, so I wonder why they were there in the first
place.

if no poll descriptor was given via
snd_ctl_ext_t::poll_fd
or
snd_ctl_ext_callback::snd_ctl_ext_poll_descriptors().

If a poll descriptor is given the
snd_ctl_ext_callback::read_event()
callback has also to be defined
because there is no minigful default behavior.

This callback will be called when ever the poll() on
the file descriptor indicates that there is an event pending.
Therefore returning a 0 which indicates that there is no event makes no
sense.

8c0b17bca3 test/seq-decoder: enable timestamping for external subscribers
Events sent by external clients subscribed to the input port are not
timestamped.

This inconsistent behavior may surprise newbies who look at seq-decoder as
a reference example.

See the example below using "vkeybd --addr 128:0" to connect to seq-decoder,
the events sent by vkeybd are on a different queue with no timestamps:

  ...
  EVENT>>> Type = 66, flags = 0x0, time = 0 ticks
           Source = 0.1, dest = 128.0, queue = 253
           Event = Port Subscribed; 129:0 -> 128:0
  EVENT>>> Type = 66, flags = 0x1, time = 4.829712627
           Source = 0.1, dest = 128.0, queue = 0
           Event = Port Subscribed; 129:0 -> 128:0
  EVENT>>> Type = 10, flags = 0x0, time = 0 ticks
           Source = 129.0, dest = 128.0, queue = 253
           Event = Controller; ch=0, param=0, value=0
  EVENT>>> Type = 11, flags = 0x0, time = 0 ticks
           Source = 129.0, dest = 128.0, queue = 253
           Event = Program Change; ch=0, program=0
  ...

After the change events are on the main queue and are timestamped:

  ...
  EVENT>>> Type = 66, flags = 0x1, time = 4.280907223
           Source = 0.1, dest = 128.0, queue = 0
           Event = Port Subscribed; 129:0 -> 128:0
  EVENT>>> Type = 66, flags = 0x1, time = 4.280912063
           Source = 0.1, dest = 128.0, queue = 0
           Event = Port Subscribed; 129:0 -> 128:0
  EVENT>>> Type = 10, flags = 0x1, time = 4.280990702
           Source = 129.0, dest = 128.0, queue = 0
           Event = Controller; ch=0, param=0, value=0
  EVENT>>> Type = 11, flags = 0x1, time = 4.280994862
           Source = 129.0, dest = 128.0, queue = 0

cb34cee0d8 snd_user_file: avoid use wordexp
As suggested in POSIX[1], wordexp might execute the shell. If the libc
implementation does so, it will break the firefox sandbox which does
not allow exec. This happened on Alpine Linux with musl libc[2].

Since we cannot guarantee that the system wordexp implementation does
not execute shell, we cannot really use it, and need to implement the
~/ expansion ourselves.

We provide a configure option --with-wordexp for users that still may
need it, but we leave this off by default because wordexp is a large
attack vector and it is better to avoid it.

adab355f35 cleanup: Use uint*_t instead of u_int*_t everythwere
Use the standard uint{8,16,32,64}_t everywhere instead of the
non-standard u_int{8,16,32,64}_t.

This changes the types in the public headers and removes the u_int*_t
defines. This may break things. However, indentifiers ending with _t are
reserved by POSIX[1]; defining those can lead to undefined behavior.

So if you rely on alsa-lib defining those for you, then you want the
compiler to error so things can be fixed properly.

by two ways; via mapped control data, and by executing ioctl(2) with
SNDRV_PCM_IOCTL_SYNC_PTR. The former is available in a case that the
applications map the data successfully.

When utilizing alsa-lib API, the above is done by a call of
'snd_pcm_sw_params()' to hw PCM plugin. In current implementation, this
call has an side-effect to issue appl_ptr unexpectedly.

de9fe69e40 pcm: hw: add a helper function to issue appl_ptr without side-effects
After starting, PCM substream shift its state to running and applications
can move appl_ptr by several ways. When status and control data of runtime
of the PCM substream is not mapped, the applications should issue appl_ptr
to kernel land. In this case, when any PCM frames is handled by mmap
operation, the applications should issue appl_ptr to update.

This commit adds a helper function for this purpose. To avoid unexpected
change of avail_min, this commit uses a flag just to update appl_ptr.

8a3df40bce pcm: hw: add a helper function to request hwsync without side-effects
SNDRV_PCM_IOCTL_SYNC_PTR command for ioctl(2) with
SNDRV_PCM_SYNC_PTR_HWSYNC flag has an effect to update hw_ptr.
This is an alternative of SNDRV_PCM_IOCTL_HWSYNC but caller can get
current status simultaneously.

This commit adds a helper function just to issue hwsync. To avoid
side-effect to change appl_ptr and avail_min, this commit uses
SNDRV_PCM_SYNC_PTR_APPL and SNDRV_PCM_SYNC_PTR_AVAIL_MIN flags.

78f3165a9e pcm: hw: add a helper function just to query status data
When mapping status data successfully, mapped page includes status data
for applications. In this case, applications have no need to call ioctl(2)
with SNDRV_PCM_IOCTL_SYNC_PTR. However, in current implementation, when
map of control data is unavailable, applications execute the ioctl(2).
This is inconvenient for some cases that applications require to query
status only.

This commit adds a helper function to query status data without issuing
the control in fallback mode from failure of status mmap.

ce0905c3ca pcm: hw: add a helper function to query status/control data
When executing ioctl(2) with some commands, applications can request
ALSA PCM core to change appl_ptr in kernel space. Below is a list of
such operations:
 - SNDRV_PCM_IOCTL_PREPARE
 - SNDRV_PCM_IOCTL_RESET
 - SNDRV_PCM_IOCTL_REWIND
 - SNDRV_PCM_IOCTL_FORWARD
 - SNDRV_PCM_IOCTL_WRITEI_FRAMES
 - SNDRV_PCM_IOCTL_WRITEN_FRAMES
 - SNDRV_PCM_IOCTL_READI_FRAMES
 - SNDRV_PCM_IOCTL_READN_FRAMES

After these operations, the value of appl_ptr should be synchronized
between kernel/user spaces.

This commit adds a helper function to query status and control data
without issuing the control data just in fallback from failure of control
mapping.

4396c83a4d pcm: hw: minor refactoring for initialization of control data
At failure of control data mapping, alsa-lib goes to fallback mode. In
this mode, a buffer is kept in user space and executes ioctl(2) with
SNDRV_PCM_IOCTL_SYNC_PTR for the buffer to synchronize the control data.

In current implementation, no helper function is used for initialize
the control data. This commit use an proper helper function instead of
a direct call of ioctl(2).

8ef3805f1b pcm: hw: Call USER_PVERSION ioctl at open
Up from the new PCM protocol 2.0.14, user-space can inform the
protocol version it supports to kernel, so that the kernel may switch
its behavior depending on it.  Add this ioctl call in the PCM hw
plugin at opening.

The patch contains also the addition of SNDRV_PCM_INFO_SYNC_APPLPTR
carried from the upstream kernel commit 42f945970af9 ("ALSA: pcm: Add
the explicit appl_ptr sync support"), as well as the trivial change
(an addition of comma) to sync with the kernel asound.h.

48bf3d3e96 pcm: hw: maintain fallback mode for control data mapping independently
Currently, failures of status/control data mapping are handled dependently.
However, it's not sure that one of the operations is failed when another
is failed.

This commit adds a member into private data structure to maintain fallback
mode for control data mapping, independently of status data mapping. As a
result, we have four cases to handle status/control data:

1. both of status/control data are mapped.
Nothing changed. A structure with alias of 'snd_pcm_hw_t' already has two
members to point the mapped area and in application runtime they're used
to refer/set status/control data. No need to call ioctl(2) with
SNDRV_PCM_IOCTL_SYNC_PTR to issue/query the data.

2. both of status/control data are unmapped.
The two members point to allocated memory for fallback buffer. In
application runtime, the buffer is given as an argument for ioctl(2) with
SNDRV_PCM_IOCTL_SYNC_PTR to issue/query the data.

3. status data is mapped only.
One of the two members is used to point the mapped area. Another points to
allocated memory for fallback buffer. In application runtime, the buffer
is used as an argument to execute ioctl(2) with SNDRV_PCM_IOCTL_SYNC_PTR
for the latter data, but the former data is already synchronized.

4. control data is mapped only.
The same as the above.

In design of ALSA PCM interface, userspace applications are not expected
to map the status data as writable. On the other hand, expected to map
the control data as writable. In a focus on the differences, we could
achieve to reduce calls of the ioctl(2) in a case that one of the
status/control data is successfully mapped and another is failed (case 3
and 4). Especially, in current alsa-lib implementation, application
runtime queries state of runtime of PCM substream so often.

9c9e3d0822 pcm: hw: maintain fallback mode for status data mapping
In current implementation, results to map status/control data are not
maintained separately. It's handled as a fatal error that mapping of status
data is successful and mapping of control data is failed. However, it's
possible to handle this case by utilizing fallback buffer.

This commit adds a member into a local structure to maintain fallback mode
just for the mapping of status data as a preparation of later commit, in
which mapping results are maintained separately for each of status/control
data.

afadf61e44 pcm: hw: allocate fallback buffer in advance of trials of mapping
When allowing failure of map operation for both of status/control data
for runtime of PCM substream, applications need to use fallback buffer
for an alternative ioctl. However, in current implementation, status
mapping is dominant to the allocation.

This commit moves code for the allocation outside of the mapping
operation for status data.
