The existing code maximizes confusion by using 'stream' and 'hstream'
variables of different types. Examples:
struct hdac_stream *stream;
struct hdac_ext_stream *stream;
struct hdac_stream *hstream;
struct hdac_ext_stream *hstream;
with some additional copy/paste remains:
struct hdac_ext_stream *azx_dev;
This patch suggests a consistent naming across all 'hdac_ext_stream'
functions. The convention is:
struct hdac_stream *hstream;
struct hdac_ext_stream *hext_stream;
No functionality change - just renaming of variables and more
consistent indentation.

Regarding to handling [U|S][32|24] PCM formats, many userspace
application developers and driver developers have confusion, since they
require them to understand justification or padding. It easily
loses consistency and soundness to operate with many type of devices. In
this commit, I attempt to solve the situation by adding comment about
relation between [S|U]32 formats and 'msbits' hardware parameter.
The formats are used for 'left-justified' sample format, and the available
bit count in most significant bit is delivered to userspace in msbits
hardware parameter (struct snd_pcm_hw_params.msbits), which is decided by
msbits constraint added by pcm drivers (snd_pcm_hw_constraint_msbits()).
In driver side, the msbits constraint includes two elements; the physical
width of format and the available width of the format in most significant
bit. The former is used to match SAMPLE_BITS of format. (For my
convenience, I ignore wildcard in the usage of the constraint.)
As a result of interaction between ALSA pcm core and ALSA pcm application,
when the format in which SAMPLE_BITS equals to physical width of the
msbits constaint, the msbits parameter is set by referring to the
available width of the constraint. When the msbits parameter is not
changed in the above process, ALSA pcm core set it alternatively with
SAMPLE_BIT of chosen format.
In userspace application side, the msbits is only available after calling
ioctl(2) with SNDRV_PCM_IOCTL_HW_PARAMS request. Even if the hardware
parameter structure includes somewhat value of SAMPLE_BITS interval
parameter as width of format, all of the width is not always available
since msbits can be less than the width.
I note that [S|U]24 formats are used for 'right-justified' 24 bit sample
formats within 32 bit frame. The first byte in most significant bit
should be invalidated. Although the msbits exposed to userspace should be
zero as invalid value, actually it is 32 from physical width of format.

This is a second attempt to unify the x86-specific SG-buffer handling
code with the new standard non-contiguous page handler.
The first try (in commit 2d9ea39917) failed due to the wrong page
and address calculations, hence reverted. (And the second try failed
due to a copy&paste error.) Now it's corrected with the previous fix
for noncontig pages, and the proper sg page iteration by this patch.
After the migration, SNDRV_DMA_TYPE_DMA_SG becomes identical with
SNDRV_DMA_TYPE_NONCONTIG on x86, while others still fall back to
SNDRV_DMA_TYPE_DEV.

When a codec is unbound dynamically via sysfs while its stream is in
use, we may face a potential deadlock at the proc remove or a UAF.
This happens since the hda_pcm is managed by a linked list, as it
handles the hda_pcm object release via kref.
When a PCM is opened at the unbinding time, the release of hda_pcm
gets delayed and it ends up with the close of the PCM stream releasing
the associated hda_pcm object of its own. The hda_pcm destructor
contains the PCM device release that includes the removal of procfs
entries. And, this removal has the sync of the close of all in-use
files -- which would never finish because it's called from the PCM
file descriptor itself, i.e. it's trying to shoot its foot.
For addressing the deadlock above, this patch changes the way to
manage and release the hda_pcm object. The kref of hda_pcm is
dropped, and instead a simple refcount is introduced in hda_codec for
keeping the track of the active PCM streams, and at each PCM open and
close, this refcount is adjusted accordingly. At unbinding, the
driver calls snd_device_disconnect() for each PCM stream, then
synchronizes with the refcount finish, and finally releases the object
resources.

We've had an x86-specific SG-buffer handling code, but now it can be
merged gracefully with the standard non-contiguous DMA pages.
After the migration, SNDRV_DMA_TYPE_DMA_SG becomes identical with
SNDRV_DMA_TYPE_NONCONTIG on x86, while others still fall back to
SNDRV_DMA_TYPE_DEV.
The remaining problem is about the SG-buffer with WC pages: the DMA
core stuff on x86 doesn't treat it well, so we still need some special
handling to manipulate the page attribute manually. The mmap handler
for SNDRV_DMA_TYPE_DEV_SG_WC still returns -ENOENT intentionally for
the fallback to the default handler.

Following to the addition of non-contiguous pages, this patch adds the
new contiguous non-coherent page allocation to the standard memalloc
helper. Like the previous non-contig type, this non-coherent type is
also directional and requires the explicit sync, too. Hence the
driver using this type of buffer may need to set
SNDRV_PCM_INFO_EXPLICIT_SYNC flag to the PCM hardware.info as well,
unless it's set up in the managed mode.

This patch adds the support for allocation of non-contiguous DMA pages
in the common memalloc helper. It's another SG-buffer type, but
unlike the existing one, this is directional and requires the explicit
sync / invalidation of dirty pages on non-coherent architectures.
For this enhancement, the following points are changed:
- snd_dma_device stores the DMA direction.
- snd_dma_device stores need_sync flag indicating whether the explicit
sync is required or not.
- A new variant of helper functions, snd_dma_alloc_dir_pages() and
*_all() are introduced; the old snd_dma_alloc_pages() and *_all()
kept as just wrappers with DMA_BIDIRECTIONAL.
- A new helper snd_dma_buffer_sync() is introduced; this gets called
in the appropriate places.
- A new allocation type, SNDRV_DMA_TYPE_NONCONTIG, is introduced.
When the driver allocates pages with this new type, and it may require
the SNDRV_PCM_INFO_EXPLICIT_SYNC flag set to the PCM hardware.info for
taking the full control of PCM applptr and hwptr changes (that implies
disabling the mmap of control/status data). When the buffer
allocation is managed by snd_pcm_set_managed_buffer(), this flag is
automatically set depending on the result of dma_need_sync()
internally. Otherwise, if the buffer is managed manually, the driver
has to set the flag explicitly, too.
The explicit sync between CPU and device for non-coherent memory is
performed at the points before and after read/write transfer as well
as the applptr/hwptr syncptr ioctl. In the case of mmap mode,
user-space is supposed to call the syncptr ioctl with the hwptr flag
to update and fetch the status at first; this corresponds to CPU-sync.
Then user-space advances the applptr via syncptr ioctl again with
applptr flag, and this corresponds to the device sync with flushing.
Other than the DMA direction and the explicit sync, the usage of this
new buffer type is almost equivalent with the existing
SNDRV_DMA_TYPE_DEV_SG; you can get the page and the address via
snd_sgbuf_get_page() and snd_sgbuf_get_addr(), also calculate the
continuous pages via snd_sgbuf_get_chunk_size().
For those SG-page handling, the non-contig type shares the same ops
with the vmalloc handler. As we do always vmap the SG pages at first,
the actual address can be deduced from the vmapped address easily
without iterating the SG-list.

Signed-off-by: Takashi Iwai <tiwai@suse.de>
It seems that a few recent AMD systems show the codec configuration
errors at the early boot, while loading the driver at a later stage
works magically. Although the root cause of the error isn't clear,
it's certainly not bad to allow retrying the codec probe in such a
case if that helps.
This patch adds the capability for retrying the probe upon codec probe
errors on the certain AMD platforms. The probe_work is changed to a
delayed work, and at the secondary call, it'll jump to the codec
probing.
Note that, not only adding the re-probing, this includes the behavior
changes in the codec configuration function. Namely,
snd_hda_codec_configure() won't unregister the codec at errors any
longer. Instead, its caller, azx_codec_configure() unregisters the
codecs with the probe failures *if* any codec has been successfully
configured. If all codec probe failed, it doesn't unregister but let
it re-probed -- which is the most case we're seeing and this patch
tries to improve.
Even if the driver doesn't re-probe or give up, it will go to the
"free-all" error path, hence the leftover codecs shall be disabled /
deleted in anyway.

Mirror changes done in SOF tree. The changes do not rely on
BIT/GENMASK on purpose to keep the structure and flags common with the
firmware tree.
The DAI_CONFIG IPC is currently used in multiple ways. It is sent to
the DSP firmware when enabling static or dynamic pipelines, in
hw_params or prepare callbacks for Intel SSP, HDaudio and ALH, on
trigger_stop and hw_free.
This IPC has been abused a bit in the past, i.e. the values used for
some of the DAI-specific fields are used to either allocate or free
resources. Two typical examples are Intel HDaudio and SoundWire/ALH
DAIs, where using a zero DMA channel number or stream tag signals to
the firmware the DMA channels or tags allocated earlier can be freed.
Rather than add a new IPC for 'hw_params' and 'hw_free', this patch
suggests supporting a 2-bit value conveying the 'stage' information in
an existing IPC structure. Only 3 possible values are used.
The mapping between HW_PARAMS and HW_FREE flags and ALSA definitions
is not strictly 1:1, e.g. in some cases the HW_PARAM flag might be set
during the .prepare callback, while the HW_FREE might be sent during the
ALSA .trigger for stop/suspend.
The semantics of the flags is to reserve and start/stop all needed
resources, typically hardware related such as DMAs or clocks, when the
HW_PARAMS is set, while the HW_FREE flag allows the firmware to
release the resources allocated. The data transfers are still
controlled within the firmware through the propagation of the trigger
command.
The driver can then pass information that the DAI_CONFIG was invoked
in e.g. a pipeline/DAI setup, hw_params or hw_free stage without
having to use a special DAI-specific encoding. Unfortunately we can't
remove old encodings due to backwards-compatibility requirements but
for new cases, such as the SSP in follow-up patches, we can make the
IPC less cryptic.
This change is tagged as ABI 3.19 and is completely backwards compatible.

In the SOF driver, the operations performed in the complete callback
can fail and therefore topology loading should return an error in
such cases. So, change the signature of the complete op
in struct snd_soc_tplg_ops to return an int to return the error.
Also, amend the complete callback functions in the SOF driver and
the SKL driver to conform with the new signature.

This simplification allows the use of the standard kernel pattern of
static inline dummy functions for debugfs code. Most systems will only
have a small number of snd_soc_components so the memory impact is
minimal.

The code for hdac_ext_stream seems inherited from hdac_stream, and
similar locking issues are present: the use of the bus->reg_lock
spinlock is inconsistent, with only writes to specific fields being
protected.
Apply similar fix as in hdac_stream by protecting all accesses to
'link_locked' and 'decoupled' fields, with a new helper
snd_hdac_ext_stream_decouple_locked() added to simplify code
changes.

The new framing mode causes the user space regression, because
the alsa-lib code does not initialize the reserved space in
the params structure when the device is opened.
This change adds SNDRV_RAWMIDI_IOCTL_USER_PVERSION like we
do for the PCM interface for the protocol acknowledgment.

Hi,
SOF is marking all componet drivers with module_get_upon_open = 1 which works
fine with normal PCM streams, however on compressed side the module get upon
open is not supported. The module_get works when module_get_upon_open is not set
becasue the snd_soc_component_module_get_when_probe() will pass NULL for the
substream parameter of snd_soc_component_module_get().
In order to re-use the existing infrastructure for module_get, the proposal is
to convert the mark_module to void pointer (like the pm mark) and implement
matching code for the compressed open/free to pcm open/close.
Regards,
Peter

The current limit of 128 is not sufficient when more components are
added to the audio map on Tegra210 and later platforms. Thus it is
resulting in probe failure.
The requirement is of nearly ~200 DAI links. To give sufficient room
for future additions the maximum limit is increased to 512 DAI links.
This is a preparatory patch to add more components like resampler,
mixer, multiplexers, demultiplexers and volume controllers to Tegra210
and later platforms.

Currently the try_module_get() and module_put() is not possible for
compressed streams if the module_get_upon_open is set to 1 which means that\
the components are not protected in a same way as components when normal
audio is used.
SOF is setting module_get_upon_open to 1 for component drivers which works
correctly for audio stream but when compressed stream is used then the
module is not protected.
Convert the compress open and free operation to mimic the steps of it's
pcm counterpart to fix this issue.

The mark_module of the snd_soc_component is strict snd_pcm_substream type
which prevents it to be used by compressed streams.
Change the type to void* along with the snd_soc_component_module_get()
and snd_soc_component_module_put() to allow the same mark to be used by
compressed when it's module_get_upon_open is set to 1.

On start/pause_release/resume, when more than one FE is connected to
the same BE, it's possible that the trigger is sent more than
once. This is not desirable, we only want to trigger a BE once, which
is straightforward to implement with a refcount.
For stop/pause/suspend, the problem is more complicated: the check
implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a
conceptual deadlock when we trigger the BE before the FE. In this
case, the FE states have not yet changed, so there are corner cases
where the TRIGGER_STOP is never sent - the dual case of start where
multiple triggers might be sent.
This patch suggests an unconditional trigger in all cases, without
checking the FE states, using a refcount protected by a spinlock.

The recent refactoring of es1688 object creation with the use of
devres caused a problem with the non-PnP probe of GUS driver, as it
tries to probe multiple times with different parameters That is, this
object needs the immediate resource release and the devres doesn't fit
for it.
This patch reverts partially the commit for restoring the classic
resource management for es1688 object.

A few drivers want to have rather the exact buffer preallocation at
the driver probe time and keep using it for the whole operations
without allowing dynamic buffer allocation. For satisfying the
demands, this patch extends the managed buffer allocation API
slightly.
Namely, when 0 is passed to max argument of the allocation helper
functions snd_pcm_set_managed_buffer*(), it treats as if the fixed
size allocation of the given size. If the pre-allocation fails in
this mode, the function returns now -ENOMEM. Otherwise, i.e. max
argument is non-zero, the function never returns -ENOMEM but tries to
fall back to the smaller chunks and allows the dynamic allocation
later -- which is still the default behavior until now.
For more intuitive use, also two new helpers are added for handling
the fixed size buffer allocation, too: snd_pcm_set_fixed_buffer() and
snd_pcm_set_fixed_buffer_all().
