When drivers register no flags about information of PCM hardware, ALSA
PCM core fixups it roughly. Currently, this operation places in a
function snd_pcm_hw_refine(). It can be moved to a function
fixup_unreferenced_params() because it doesn't affects operations
between these two functions.
This idea is better to bundle codes with similar purposes and this commit
achieves it.

A structure for parameters of PCM runtime has parameters which are
not classified as mask/interval type. They are decided only when
corresponding normal parameters have unique values.
* struct snd_pcm_hw_params.msbits
* struct snd_pcm_hw_params.rate_num
* struct snd_pcm_hw_params.rate_den
* struct snd_pcm_hw_params.fifo_size
Current implementation of hw_params ioctl sometimes doesn't decide these
parameters even if corresponding parameters are fixed, because these
parameters are evaluated before a call of snd_pcm_hw_params_choose().
This commit adds a helper function to process the parameters and call it
in proper positions.

Drivers add rules of parameters to runtime of PCM substream, when
applications open ALSA PCM character device. When applications call
ioctl(2) with SNDRV_PCM_IOCTL_HW_REFINE or SNDRV_PCM_IOCTL_HW_PARAMS, the
rules are applied to the parameters and return the result to user space.
The rule can have dependency between parameters. Additionally, it can have

When working for devices which support configurable modes for its data

refinement of parameters for PCM substream. Although this is merely a
makeshift. With some modifications, we get the infrastructure.

For accessing the snd_timer_user queue indices, we take tu->qlock.
But it's forgotten in a couple of places.
The one in snd_timer_user_params() should be safe without the
spinlock as the timer is already stopped. But it's better for
consistency.
The one in poll is just a read-out, so it's not inevitably needed, but
it'd be good to make the result consistent, too.

ALSA timer may reallocate the user queue upon request, and it happens
at three places for now: at opening, at SNDRV_TIMER_IOCTL_PARAMS, and
at SNDRV_TIMER_IOCTL_SELECT. However, the last one,
snd_timer_user_tselect(), doesn't need to reallocate the buffer since
it doesn't change the queue size. It does just because tu->tread
might have been changed before starting the timer.
Instead of *_SELECT ioctl, we should reallocate the queue at
SNDRV_TIMER_IOCTL_TREAD; then the timer is guaranteed to be stopped,
thus we can reassign the buffer more safely.
This patch implements that with a slight code refactoring.
Essentially, the patch achieves:
- Introduce realloc_user_queue() for (re-)allocating the ring buffer,
and call it from all places. Also, realloc_user_queue() uses
kcalloc() for avoiding possible leaks.
- Add the buffer reallocation at SNDRV_TIMER_IOCTL_TREAD. When it
fails, tu->tread is restored to the old value, too.
- Drop the buffer reallocation at snd_timer_user_tselect().

snd_timer_user_tselect() reallocates the queue buffer dynamically, but

In recent commit for ALSA PCM core, some arrangement is done for
'struct snd_pcm_ops.ack' callback. This is called when appl_ptr is
explicitly moved in intermediate buffer for PCM frames, except for
some cases described later.
For drivers in ALSA firewire stack, usage of this callback has a merit to
reduce latency between time of PCM frame queueing and handling actual
packets in recent isochronous cycle, because no need to wait for software
IRQ context from isochronous context of OHCI 1394.
If this works well in a case that mapped page frame is used for the
intermediate buffer, user process should execute some commands for ioctl(2)
to tell the number of handled PCM frames in the intermediate buffer just
after handling them. Therefore, at present, with a combination of below
conditions, this doesn't work as expected and user process should wait for
the software IRQ context as usual:
- when ALSA PCM core judges page frame mapping is available for status
data (struct snd_pcm_mmap_status) and control data
(struct snd_pcm_mmap_control).
- user process handles PCM frames by loop just with 'snd_pcm_mmap_begin()'
and 'snd_pcm_mmap_commit()'.
- user process uses PCM hw plugin in alsa-lib to operate I/O without
'sync_ptr_ioctl' option.
Unfortunately, major use case include these three conditions.

structure members we were storing data in.
Once we delete sst_save_shim64() there are no longer any users of the

and also avoid allocating memory for it. This saves a whopping 136
bytes of devm allocated memory. We also get the nice benefit of
avoiding an error path in the init code.

now. This became possible since we switched to byte size to copy_*
and fill_silence ops argument instead of frames.
And, for both read and write, we can use the same copy function (which
is defined as pcm_copy_f), just depending on whether interleaved or
non-interleaved mode.
The transfer function is determined at the beginning of the loop,
depending on whether the driver gives the specific copy ops or it's
the standard read/write.
Another bonus by this change is that we now guarantee the silencing
behavior when NULL buffer is passed to write helpers. It'll simplify
some codes later.

For supporting the explicit in-kernel copy of PCM buffer data, and
also for further code refactoring, three new PCM ops, copy_user,
copy_kernel and fill_silence, are introduced. The old copy and
silence ops will be deprecated and removed later once when all callers
are converted.
The copy_kernel ops is the new one, and it's supposed to transfer the
PCM data from the given kernel buffer to the hardware ring-buffer (or
vice-versa depending on the stream direction), while the copy_user ops
is equivalent with the former copy ops, to transfer the data from the
user-space buffer.
The major difference of the new copy_* and fill_silence ops from the
previous ops is that the new ops take bytes instead of frames for size
and position arguments. It has two merits: first, it allows the
callback implementation often simpler (just call directly memcpy() &
co), and second, it may unify the implementations of both interleaved
and non-interleaved cases, as we'll see in the later patch.
As of this stage, copy_kernel ops isn't referred yet, but only
copy_user is used.

The previous commit [63691587f7: ALSA: hda - Apply dual-codec quirk
for MSI Z270-Gaming mobo] attempted to apply the existing dual-codec
quirk for a MSI mobo. But it turned out that this isn't applied
properly due to the MSI-vendor quirk before this entry. I overlooked
such two MSI entries just because they were put in the wrong position,
although we have a list ordered by PCI SSID numbers.
This patch fixes it by rearranging the unordered entries.

that snd_usb_ctl_msg() writes back the response to the given buffer,
while the patch changed it to a read-only const buffer. (One should
always double-check when an extra pointer cast is present...)
As a simple fix, just revert the affected commit. It was merely a
cleanup. Although it brings VLA again, it's clearer as a fix. We'll

due to the forgotten negative appl_ptr update in indirect-PCM helper,
which is the major user of the PCM ack callback. But now we fixed

In design of ALSA pcm core, 'struct snd_pcm_ops.copy' is expected to
copy PCM frames, according to frame alignment on intermediate buffer for
userspace and dedicated buffer for data transmission. In this callback,
value of 'channel' argument depends on the frame alignment, which drivers
registers to runtime of PCM substream. When target devices can handle
non-interleaved buffer, this value has positive value, otherwise negative.
ALSA driver for PCM component of EMU8000 chip is programmed with local
macro to switch the frame alignment. The 'copy' operation in
non-interleaved side has evaluation of the 'channel' argument (actually
it's 'voice' argument). This is useless.
This commit remove the evaluation.
[tiwai: the negative channel argument was the inheritance from the old
code where -1 was meant for interleaved mode. The mix-up was dropped
meanwhile, thus it's correct to assume that we receive no longer -1
there, and it's safe to cleanup the relevant code.
Also, voice=0 for channel==1 is trivial, and it can be dropped, too.]

DesignWare HDMI driver (= dw-hdmi) is supporting HDMI sound, and its

same HDMI device different port.
Because of this behavior, commit 9731f82d60 ("ASoC: hdmi-codec: enable

But, this DesignWare HDMI detection/bind code was exchanged/adjusted by

In SKL+ platforms, all IPC commands are serialised, i.e. the driver sends
a new IPC to DSP, only after receiving a reply from the firmware for the
current IPC.
Hence it seems apparent that there is only a single modifier of the IPC RX
List. However, during an IPC timeout case in a multithreaded environment,
there is a possibility of the list element being deleted two times if not
properly protected.
So, use spin lock save/restore to prevent rx_list corruption.

soc_cleanup_card_resources() call snd_card_free() at the last of its
procedure. This turned out to lead to a use-after-free.
PCM runtimes have been already removed via soc_remove_pcm_runtimes(),
while it's dereferenced later in soc_pcm_free() called via
snd_card_free().
The fix is simple: just move the snd_card_free() call to the beginning
of the whole procedure. This also gives another benefit: it
guarantees that all operations have been shut down before actually
releasing the resources, which was racy until now.

In current implementation of ALSA control core, list operation has
a limitation to handle 16384 entries at once. This seems due to
allocation in kernel space to copy data from user space.
With a commit 53e7bf4525 ("ALSA: control: Simplify snd_ctl_elem_list()

into user space directly. No need to care of kernel spaces anymore.

We used to use kmalloc (more exactly, krealloc()) for creating and
growing the temporary buffer for text proc write. It can grow up to
16kB, and it's already a bit doubtful whether it's always safe to use

PCM core code has a few usages of set_fs(), mostly for two codepaths:
- The DELAY ioctl call from pcm_compat.c
- The ioctl wrapper in kernel context for PCM OSS and other
This patch removes the set_fs() usage in these places by a slight code
refactoring. For the former point, snd_pcm_delay() is changed to
return the value directly instead of putting the value to the given
address. Each caller stores the result in an appropriate manner.
For fixing the latter, snd_pcm_lib_kernel_ioctl() is changed to call
the functions directly as well. For achieving it, now the function
accepts only the limited set of ioctls that have been used, so far.
The primary user of this function is the PCM OSS layer, and the only
other user is USB UAC1 gadget driver. Both drivers don't need the
full set of ioctls.

This patch simplifies the code of snd_ctl_elem_list() in the following
ways:
- Avoid a vmalloc() temporary buffer but do copy in each iteration;
the vmalloc buffer was introduced at the time we took the spinlock
for the ctl element management.
- Use the standard list_for_each_entry() macro
- Merge two loops into one;
it used to be a loop for skipping until offset becomes zero and
another loop to copy the data. They can be folded into a single
loop easily.

In IEC 61883-6, AM824 is described as format of data block. In this
format, one data block consists of several data channels, which is aligned
to 32 bit. One data channel has 8 bit label field and 24 bit data field.
PCM frames are transferred in Multi Bit Linear Audio (MBLA) data channel.
This channel can include 16/20/24 bit PCM sample.
As long as I know, models which support IEC 61883-1/6 doesn't allow to
switch bit length of PCM sample in MBLA data channel. They always
transmit/receive PCM frames of 24 bit length. This can be seen for the
other models which support protocols similar to IEC 61883-1/6.
On the other hand, current drivers for these protocols supports 16 bit
length PCM sample in playback substream. In this case, PCM sample is put
into the MBLA data channel with 8 bit padding in LSB side. Although 16
bit PCM sample is major because it's in CD format, this doesn't represent
device capability as is.
This commit removes support for 16 bit PCM samples in playback substream.

Not calling pm_runtime_enable() means that runtime PM can't be
enabled at all via sysfs. So we definitely need to call it
from somewhere.
Calling it from the driver seems like a bad idea because it
would have to be paired with a pm_runtime_disable() at driver
unload time, otherwise the core gets upset. Also if there's
no LPE audio driver loaded then we couldn't runtime suspend
i915 either.
So it looks like a better plan is to call it from i915 when
we register the platform device. That seems to match how
pci generally does things. I cargo culted the
pm_runtime_forbid() and pm_runtime_set_active() calls from
pci as well.
The exposed runtime PM API is massive an thorougly misleading, so
I don't actually know if this is how you're supposed to use the API
or not. But it seems to work. I can now runtime suspend i915 again
with or without the LPE audio driver loaded, and reloading the
LPE audio driver also seems to work.
Note that powertop won't auto-tune runtime PM for platform devices,
which is a little annoying. So I'm not sure that leaving runtime
PM in "on" mode by default is the best choice here. But I've left
it like that for now at least.
Also remove the comment about there not being much benefit from
LPE audio runtime PM. Not allowing runtime PM blocks i915 runtime
PM, which will also block s0ix, and that could have a measurable
impact on power consumption.

Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M
broadwell-audio and rt286 codec. For all versions of Linux kernel,
the stereo output doesn't work properly when earphones are plugged
in, the sound was coming out from both channels even if the audio
contains only the left or right channel. Furthermore, if a music
recorded in stereo is played, the two channels cancle out each other
out, as a result, no voice but only distorted background music can be
heard, like a sound card with builtin a Karaoke sount effect.
Apparently this tablet uses a combo jack with polarity incorrectly
set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2
to force_combo_jack_table[] and the issue is resolved. The microphone
input doesn't work regardless to the presence of this patch and still

Pull hw lockdown support from David Howells:
"Annotation of module parameters that configure hardware resources
including ioports, iomem addresses, irq lines and dma channels.
This allows a future patch to prohibit the use of such module
parameters to prevent that hardware from being abused to gain access
to the running kernel image as part of locking the kernel down under
UEFI secure boot conditions.
Annotations are made by changing:
module_param(n, t, p)
module_param_named(n, v, t, p)
module_param_array(n, t, m, p)
to:
module_param_hw(n, t, hwtype, p)
module_param_hw_named(n, v, t, hwtype, p)
module_param_hw_array(n, t, hwtype, m, p)
where the module parameter refers to a hardware setting
hwtype specifies the type of the resource being configured. This can
be one of:
ioport Module parameter configures an I/O port
iomem Module parameter configures an I/O mem address
ioport_or_iomem Module parameter could be either (runtime set)
irq Module parameter configures an I/O port
dma Module parameter configures a DMA channel
dma_addr Module parameter configures a DMA buffer address
other Module parameter configures some other value
Note that the hwtype is compile checked, but not currently stored (the
lockdown code probably won't require it). It is, however, there for
future use.
A bonus is that the hwtype can also be used for grepping.
The intention is for the kernel to ignore or reject attempts to set
annotated module parameters if lockdown is enabled. This applies to
options passed on the boot command line, passed to insmod/modprobe or
direct twiddling in /sys/module/ parameter files.
The module initialisation then needs to handle the parameter not being
set, by (1) giving an error, (2) probing for a value or (3) using a
reasonable default.
What I can't do is just reject a module out of hand because it may
take a hardware setting in the module parameters. Some important
modules, some ipmi stuff for instance, both probe for hardware and
allow hardware to be manually specified; if the driver is aborts with
any error, you don't get any ipmi hardware.
Further, trying to do this entirely in the module initialisation code
doesn't protect against sysfs twiddling.
[!] Note that in and of itself, this series of patches should have no
effect on the the size of the kernel or code execution - that is
left to a patch in the next series to effect. It does mark
annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
an already existing field"

Not calling pm_runtime_enable() means that runtime PM can't be
enabled at all via sysfs. So we definitely need to call it
from somewhere.
Calling it from the driver seems like a bad idea because it
would have to be paired with a pm_runtime_disable() at driver
unload time, otherwise the core gets upset. Also if there's
no LPE audio driver loaded then we couldn't runtime suspend
i915 either.
So it looks like a better plan is to call it from i915 when
we register the platform device. That seems to match how
pci generally does things. I cargo culted the
pm_runtime_forbid() and pm_runtime_set_active() calls from
pci as well.
The exposed runtime PM API is massive an thorougly misleading, so
I don't actually know if this is how you're supposed to use the API
or not. But it seems to work. I can now runtime suspend i915 again
with or without the LPE audio driver loaded, and reloading the
LPE audio driver also seems to work.
Note that powertop won't auto-tune runtime PM for platform devices,
which is a little annoying. So I'm not sure that leaving runtime
PM in "on" mode by default is the best choice here. But I've left
it like that for now at least.
Also remove the comment about there not being much benefit from
LPE audio runtime PM. Not allowing runtime PM blocks i915 runtime
PM, which will also block s0ix, and that could have a measurable
impact on power consumption.

- A fix from Mousumi Jana for issues with incorrectly created
enumeration controls generated from topology files which could cause
problems for userspace.
- Fixes from Arnaud Pouliquen for some crashes due to races with the

The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry
the ignore_suspend flag, and this prevents the suspend/resume working
properly while the stream is running, since SST core code has the
check of the running streams and returns -EBUSY. Drop these
superfluous flags for fixing the behavior.
Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE
definitions, which leads to the kernel Oops at suspend/resume like:

The bytcr-rt5640 driver has a few quirk setups depending on the board,
where the quirk value is set by DMI matching. When you have a new
device to add the support, you often experience to try the different
quirk by trial-and-error. Or, you may have a development model that
still has no proper DMI string. In either case, you'd need to compile
the driver at each time.
This patch introduces a module option to override the quirk value on
the fly. User can boot like snd-soc-sst-bytcr-rt5640.quirk=0x4004 to
override the default value without recompilation. It's a raw value,
so user needs to check the source code for the meaning of each bit.

Since recently UCM can pick up a configuration specific to the board
via card longname field, and we introduced a helper function
snd_soc_set_dmi_name() for that. So far, it was used only in one
place (sound/soc/intel/boards/broadwell.c), but it should be more
widely applied.
This patch puts a big hammer for that: it lets snd_soc_register_card()
calling snd_soc_set_dmi_name() unconditionally, so that all x86
devices get the better longname string. This would have no impact for
other systems without DMI support, as snd_soc_set_dmi_name() is no-op
on them.
