As noted in a previous commit, the E-MU Digital Audio System cards
don't try very hard to be Sound Blasters. This commit takes it further
and introduces a module option to switch to a completely separate mode.
In that mode:
- The regular PCM playback/capture devices are removed
- The EFX playback/capture devices get index 0
- Consequently, the regular mixer controls are also completely removed.
This is no real loss, given the expected use with a sound server.
- The voice send routing+amount & attenuation controls are also removed,
as they are just another mixer. The routing is redundant with the FPGA
channel routing, and amounts/att'n can be done in software. The latter
are also incompatible with 32-bit playback, which we'll add support
for later.
- A_EXTOUT is now also free for multi-channel capture, so we use that
instead of A_FXBUS2 - this will later simplify using both at once.
- For the same reason, the FX outputs are not listed in /proc anymore
- The device name is changed, so mixer settings don't get mixed up
This continues the pre-existing design with a single multi-channel
device where the channels are routed by manual mixer controls from/to
the physical ports. De-/multiplexing must be done by the sound server
if independent streams are to be used.
An alternative design would be exposing each physical port as a separate
device and automatically setting up the routes. This would be a somewhat
radical departure from the status quo, and I don't know whether it would
be a net benefit. It certainly would be harder to implement, as it would
require sync start of streams and a channel allocator (the latter would
have the added benefit of properly reporting EMU32 & EDI bus over-
allocation, which the mixer does not). There is only one big multi-
channel capture engine, so streams would have to be de-multiplexed by
the driver in software - which seems a bit counter-productive if the
sound server would re-multiplex them again.

Use the clearer "PbChn <n>" instead of "DSP <n>" for the source names.
In particular, this is much less confusing in the capture source
selection - "DSP 0" having the source "DSP 0" really didn't help.
I didn't use "Playback Channel <n>", because that would be a tad too
long to be sensibly displayed in alsamixer.
The capture enums also get a "DSP" => "CpChn" replacement.
I used zero-padded decimals, so the capture elements are properly sorted
in alsamixer. I found hex too confusing.
Note that unlike in the legacy mixer, we define enum values only for
actually "wired" channels.
I'm leaving the legacy mixer alone, as I don't want to completely
invalidate saved mixer states. This introduces some bloat, but it seems
bearable.

... on Audigy, when we are not pitch-shifting.
The only observable effect is that the Z1/Z2/FXBUS registers don't have
a stray bit set for negative numbers anymore. The bit is below the ones
significant for output, but it would mess with 32-bit sample
recombination, which we are about to add.
kX-project does that, but I had to figure out myself why.

Each channel now uses a stereo voice pair. But the FX send amounts and
attenuation are per voice, so we have to use fixed values tuned to the
DSP code to avoid messing up the split samples.
As "regular" mode allows manipulating the amounts and att'n via mixer
controls, we can either:
- "Fake" them with DSP code, which doesn't seem worth the bother
- Ignore them, which doesn't seem very nice
So 32-bit playback simply remains unavailable in non-D.A.S. mode.

This is in fact more symmetrical to snd_ctl_remove() than snd_ctl_add()
is - the former could be named snd_ctl_remove_locked() just as well.
One may argue that this is going in the wrong direction, as drivers have
no business managing the lock. This may be true in principle, but in
practice the vast majority of controls is created even before the device
was registered, and therefore before any locking is necessary at all.
That means that an even more radical approach of changing snd_ctl_add()
do do no locking, and converting the call sites that actually need
locking to a new function, would better match reality, and would be
somewhat more efficient at that. However, that seems a bit risky and way
too much work.
This will be used to dynamically change the available controls from
another control's put() callback, which is already locked.
One might want to add snd_ctl_replace_locked() for completeness, but I
have no use for it now.

This lays the groundwork for supporting 88.2/96/176.4/192 kHz rates
without actually doing so yet - we simply multi-feed the same samples
on playback, and throw away the excess ones on capture. Input-to-output
monitoring does actually use the full sample rate, though.
Due to hardware constraints, changing the clock multiplier (CM) changes
the available audio ports and the number of available channels. This has
an impact on the channel routing mixer controls. One way to deal with
this would be presenting a union of all possibilities, and simply
ignoring currently inapplicable settings. However, this would be a
terrible user experience, and go against the spirit of prior patches
aimed at decluttering the mixer. Therefore, we do dynamic
reconfiguration (DR) of the mixer in response to changing the CM.
DR is somewhat controversial, as it has the potential to crash poorly
programmed applications. But that in itself isn't a very convincing
argument against it, as by that logic we'd have to ban all hot-plugging.
Such crashes would also not really qualify as regressions, as the D.A.S.
mode is a new opt-in feature, and therefore no previously stable setups
would be impacted. Also, pendantically, the driver already had DR via
SNDRV_EMU10K1_IOCTL_CODE_POKE. A somewhat valid concern is that changing
mixer settings is a non-privileged operation and therefore potential
crashes could be exploited for a somewhat more impactful nuisance attack
on another user than messing with the mixer per se. However, systemd &
co. limit device access to the user currently logged in on the seat
owning the device.
There is a specific concern about doing DR in response to changing a
mixer control's value, as an application may legitimately react to DR by
updating all mixer settings in turn. However, that update should write
the same value to the clock multiplier, thus terminating the recursion.
One may limit DR to merely disabling inapplicable controls, in the hope
that this would be better handled than completely tearing down and
re-creating controls as we do. However, there is no guarantee for that.
And because it is impossible to disable particular enum values within a
control, it would be necessary to have three complete sets of
per-channel controls. This would yield an extremely cluttered and
confusing UI if the application (reasonably) chose to merely visually
disable inactive controls rather than hiding them.
We do the DR synchronously from within snd_emu1010_clock_shift_put().
This was enabled by commit 5bbb1ab5bd ("control: use counting semaphore
as write lock for ELEM_WRITE operation"); we merely need to make
add_ctls() use snd_ctl_add_locked() instead of snd_ctl_add(), so it
doesn't deadlock. That also affects the initial creation of the
controls, which is OK, as that is done before the card is registered, so
no concurrent access can occur.
It would be possible to do the DR in a tasklet after the ioctl finishes.
However, it is not obvious what actual problem that would solve, and the
added asynchronicity would significantly complicate matters, esp. wrt.
the batch updates expected during mixer state restoration.

This is tested only with a 0404b card, so it is unclear whether the
EMU_DST_TINA_EMU32B (1010b) & EMU_DST_TINA2_EMU32B (1616m CardBus)
register definitions (derived from comments in the same file) are
correct, and whether they actually lack the one-sample delay
relative to EMU_DST_ALICE2_EMU32_0.

This mode does not offer mmapped I/O, as we need to copy the buffer
anyway to reshuffle it.
A limitation is that we'll refuse writes which aren't a multiple of 2/4
frames, but that's unlikely to be significant. But if one really wanted
to make it work, this could be done either locally, or by reviving (and
fixing) snd_pcm_sw_params.xfer_align, which was obsoleted in commit
d948035a92 ("Remove PCM xfer_align sw params").

I still can't agree with the basic design using the dynamic kctl
addition / deletion in kcontrol's put action.

The fundamental idea to add / delete the kctls from the put callback
is unacceptable; as repeated many times, this is known to break
existing applications. As long as you are sticking with this idea, it
can go further. Please avoid it and use the (more or less) static
configuration instead.

to put the implications of this in clear words:
you want me to spend additional time
on a driver barely anyone still cares about
to actively degrade the (my!) user experience
to avoid hypothetical / likely obsolete crashes
that would happen upon a rare user-controlled event
in unspecified buggy (mixer? (!)) applications,
while a known-good fallback exists (alsamixer).
i fail to see how that is even _remotely_ a reasonable request, and
therefore have no intention whatsoever to follow it.

Simply put, YES. It's breaking applications pretty easily. This
already happened in the past, so it's no hypothesis.
If you've ever programmed applications that deal with ALSA
mixer/control stuff by yourself, you'll notice that it's really tough
to deal with the dynamic deletion/addition. alsamixer can accept it
in the limited manner, but it's no fallback for everything, of
course.

well, your priorities don't align with the needs of actual users (that
would be me, in this case).

hot-plugging always requires some care to handle. i don't consider this
a showstopper, esp. in the year 2023, when udev and pulseaudio/pipewire
go all crazy on us (and yes, that crashed kmix - big deal). i don't
think it's sane to set the bar at 1995 standards. even less so when the
class of potentially affected apps holds no user data of note.

i have no clue what point you're trying to make.
