This is a preparation for allowing devres usages more widely in
various sound drivers. As a first step, this patch adds a new
allocator function, snd_devm_alloc_pages(), to manage the allocated
pages via devres, so that the pages will be automagically released as
device unbinding.
Unlike the old snd_dma_alloc_pages(), the new function returns
directly the snd_dma_buffer pointer. The caller needs NULL-check for
the allocation error appropriately.
Also, since a real device pointer is mandatory for devres,
SNDRV_DMA_TYPE_CONTINUOUS or SNDRV_DMA_TYPE_VMALLOC type can't be used
for this function.

As a second step for preliminary to widen the devres usages among
sound drivers, this patch adds a new ALSA core API function,
snd_devm_card_new(), to create a snd_card object via devres.
When a card object is created by this new function, snd_card_free() is
called automatically and the card object resource gets released at the
device unbinding time.
However, the story isn't that simple. A caveat is that we have to
call snd_card_free() at the very first of the whole resource release
procedure, in order to assure that the all exposed devices on
user-space are deleted and sync with processes accessing those devices
before releasing resources.
For achieving it, snd_card_register() adds a new devres action to
trigger snd_card_free() automatically when the given card object is a
"managed" one. Since usually snd_card_register() is the last step of
the initialization, this should work in most cases.
With all these tricks, some drivers can get rid of the whole driver
remove callback code.
About a bit of implementation details: the patch adds two new flags to
snd_card object: managed and releasing. The former indicates that the
object was created via snd_devm_card_new(), and the latter is used for
avoiding the double-free of snd_card_free() calls. Both flags are
fairly internal and likely uninteresting to normal users.

Maybe just make extra_size unsigned or even better size_t?

Not sure I understand, we are in _register function, so why do we remove
action?

OK, that would fit for a new function, indeed.

snd_card_register() can be called multiple times for re-registering
the newly added components (e.g. usb-audio driver does it). In that
case, we have to move this trigger_card_free action at the head again.

That is, what the code above cares is the case where snd_card_free()
is called explicitly even if the card is created with devres. So the
check of card->releasing could be __snd_card_release() instead in
snd_card_free(), too.

From: Takashi Iwai @ 2021-07-13 14:28 UTC (permalink / raw)
To: alsa-devel
This patch refactors the intel8x0 and intel8x0m driver codes using
devres and gets rid of the driver remove callback.
The conversion is fairly straightforward: each API call is replaced
with the device-managed API function, e.g. pci_enable_device() ->
pcim_enable_device(), and so on. The buffer descriptor list is
allocated with a new API, snd_devm_alloc_pages().
A slight code structure change is that the intel8x0 object is
allocated as a card's private_data instead of the own lowlevel
snd_device object. This simplifies the resource management.
And, the take-down procedure is triggered via card->private_free, and
it's registered at the end of the whole initialization, i.e. after the
all resources get properly managed.
The only not-devres-managed resource is the irq handler. Since we
need to release at suspend and re-acquire at resume (otherwise
something weird happens on some machines), this is still managed
manually. But the rest are all freed automatically.
The end result is a good amount of code reduction.

To: alsa-devel
Like the previous patch, this patch converts the resource allocations
with device-managed API calls, so that we can reduce resource-free
calls.
The atiixp drivers are simpler than intel8x0, and even the irq can be
allocated with devres.
The end result is a good amount of code reduction.

This patch is an attempt to slightly simplify the resource management
in HD-audio code, by using some device-managed APIs. Only a few
resources like PCI enablement and PCI resources managed via devres,
but most of the rest code dealing with HD-audio core stuff couldn't be
changed so much, hence the changes in this patch are pretty small in
the end. A special caveat is needed for the card object: we can't
move the card object release into devres, because the driver is
involved with the component stuff and its unregistiration doesn't work
well from devres release at all.

+Device-Managed Resources
+========================
+
+In the examples above, all resources are allocated and released
+manually. But human beings are lazy in nature, especially developers
+are lazier. So there are some ways to automate the release part; it's
+the (device-)managed resources aka devres or devm family. For
+example, an object allocated via :c:func:`devm_kmalloc()` will be
+freed automatically at unbinding the device.
+
+ALSA core provides also the device-managed helper, namely,
+:c:func:`snd_devm_card_new()` for creating a card object.
+Call this functions instead of the normal :c:func:`snd_card_new()`,
+and you can forget the explicit :c:func:`snd_card_free()` call, as
+it's called automagically at error and removal paths.
+
+One caveat is that the call of :c:func:`snd_card_free()` would be put
+at the beginning of the call chain only after you call
+:c:func:`snd_card_register()`.
+
+Also, the ``private_free`` callback is always called at the card free,
+so be careful to put the hardware clean-up procedure in
+``private_free`` callback. It might be called even before you
+actually set up at an earlier error path. For avoiding such an
+invalid initialization, you can set ``private_free`` callback after
+:c:func:`snd_card_register()` call succeeds.
+
+Another thing to be remarked is that you should use device-managed
+helpers for each component as much as possible once when you manage
+the card in that way. Mixing up with the normal and the managed
+resources may screw up the release order.
+
+

This patch converts the resource management in PCI ad1889 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
Also, the unnecessary ac97 free callbacks are removed, too.
This should give no user-visible functional changes.

This patch converts the resource management in PCI als300 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI bt87x driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

To: alsa-devel
This patch converts the resource management in PCI cmipci driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI esn137x drivers
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, the devres helper is
used for the DMA buffer page allocations, and the card object release
is managed now via card->private_free instead of a lowlevel
snd_device.
This should give no user-visible functional changes.

You seem to touch all uses of this variable and it seems like it has a
typo (dma_bug -> dms_buf), not sure if it can be corrected in this patch
or separate one.

This patch converts the resource management in PCI es1938 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI es1968 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI maestro3 driver
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, and the card object
release is managed now via card->private_free instead of a lowlevel
snd_device. Superfluous ac97 private_free callbacks were dropped,
too.
This should give no user-visible functional changes.

This patch converts the resource management in PCI sonicvibes driver
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, and the card object
release is managed now via card->private_free instead of a lowlevel
snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI ali5451 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

To: alsa-devel
This patch converts the resource management in PCI au88x0 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI cs46xx driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI cs5535audio driver
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, and the card object
release is managed now via card->private_free instead of a lowlevel
snd_device. A slight uncertain change is the call of
olpc_quirks_cleanup() at removal: formerly this was called
unconditionally at remove, but this should be a conditionally call,
hence the machine_is_olpc() check is added here as well.
This should give no user-visible functional changes.

This patch converts the resource management in PCI echoaudio drivers
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, the page allocations
are done with the devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
The irq handler is still managed manually because it's re-acquired at
PM suspend/resume.
This should give no user-visible functional changes.

From: Takashi Iwai @ 2021-07-13 14:28 UTC (permalink / raw)
To: alsa-devel
This patch converts the resource management in PCI emu10k1x driver
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, the page allocations
are done with the devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI ice1712 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
Along with it, the chip_exit callback chain is moved into the card's
private_free instead of the PCI remove callback, too.
This should give no user-visible functional changes.

From: Takashi Iwai @ 2021-07-13 14:28 UTC (permalink / raw)
To: alsa-devel
This patch converts the resource management in PCI lola driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI oxygen drivers with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the page allocations are
done with the devres helper.
This should give no user-visible functional changes.

This patch converts the resource management in PCI hdspm driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the resource management in PCI vx222 driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

To: alsa-devel
This patch converts the resource management in PCI ymfpci driver with
devres as a clean up. Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.
This should give no user-visible functional changes.

This patch converts the card object management with devres as a clean
up. The remove callback gets reduced by that.
This should give no user-visible functional changes.

This patch converts the resource management in serial u16550 driver
with devres as a clean up. Each manual resource management is
converted with the corresponding devres helper, and the card object
release is managed now via card->private_free instead of a lowlevel
snd_device.
This should give no user-visible functional changes.

This and the next one seem to have typos, maybe the old versions have
been smashed into the series wrongly. Will be corrected in v2 series.

* [PATCH 51/51] ALSA: mpu401: Allocate resources with device-managed APIs

To: alsa-devel
This patch converts the card object management with devres as a clean
up. The remove callback gets reduced by that.
This should give no user-visible functional changes.
Note that this converts only the mpu401 card driver. The mpu401_uart
component is still managed with snd_device. It's for the case where
the mpu401_uart component may be removed dynamically without the
actual device unbind.
