ALSA: hda - Fix mute LED on HP laptops in runtime suspend

When HP laptops with mute and mic-record LEDs go to runtime suspend,
these LEDs are turned on forcibly no matter whether GPIO pis are on or
off.  This strange behavior seems triggered by resetting the HD-audio
bus link at azx_rutime_suspend().  So, just add a new hda_bus flag to
avoid the link reset at runtime suspend and set it for these HP
machines.

ALSA: hda - hdmi: Fix channel map switch not taking effect

Currently hdmi_setup_audio_infoframe() reprograms the HDA channel
mapping only when the infoframe is not up-to-date or the non-PCM flag
has changed.

However, when just the channel map has been changed, the infoframe may
still be up-to-date and non-PCM flag may not have changed, so the new
channel map is not actually programmed into the HDA codec.

Notably, this failing case is also always triggered when the device is
already in a prepared state and a new channel map is configured while
changing only the channel positions (for example, plain
"speaker-test -c2 -m FR,FL").

Fix that by always programming the channel map in
hdmi_setup_audio_infoframe(). Tested on Intel HDMI.

ALSA: hda - hdmi: Fix programmed active channel count

Currently the converter channel count is set to the number of actual
input channels. The audio infoframe channel count field is set
similarly.

However, sometimes the used channel map does not map all input channels
to outputs. Notably, 3 channel modes (e.g. 2.1) require a dummy input
channel so there are 4 input channels. According to the HDA
specification, converter channel count should be programmed according to
the number of _active_ channels.

On Intel HDMI codecs (but not on NVIDIA), setting the converter channel
to a higher value than there are actually mapped channels to HDMI slots
will cause no audio to be output at all.

Note that the effects of this issue are currently partially masked by
other bugs that prevent the driver from actually unmapping channels in
certain cases. For example, if a 4 channel stream is first created and
prepared, it gets a FL,FR,RL,RR mapping (ALSA->HDMI slot mapping 0->0,
1->1, 2->4, 3->5). If one thereafter assigns a FR,FL,FC mapping to it,
the driver will remap 2->3 but fail to unmap 2->4 and 3->5, so there are
still 4 active channels and the issue will not trigger in this case.
These bugs will be fixed separately.

Fix the channel counts in the converter channel count field and in the
audio infoframe channel count field to match the actual number of active
channels.

If the channel allocation is not one of the ALSA standard layouts, the

11 years agoALSA: improve buffer size computations for USB PCM audio
Alan Stern [Tue, 24 Sep 2013 19:51:58 +0000 (15:51 -0400)]
ALSA: improve buffer size computations for USB PCM audio

This patch changes the way URBs are allocated and their sizes are
determined for PCM playback in the snd-usb-audio driver.  Currently
the driver allocates too few URBs for endpoints that don't use
implicit sync, making underruns more likely to occur.  This may be a
holdover from before I/O delays could be measured accurately; in any
case, it is no longer necessary.

The patch allocates as many URBs as possible, subject to four
limitations:

The total number of URBs for the endpoint is not allowed to
exceed MAX_URBS (which the patch increases from 8 to 12).

The total number of packets per URB is not allowed to exceed
MAX_PACKS (or MAX_PACKS_HS for high-speed devices), which is
decreased from 20 to 6.

The total duration of queued data is not allowed to exceed
MAX_QUEUE, which is decreased from 24 ms to 18 ms.

The total number of ALSA frames in the output queue is not
allowed to exceed the ALSA buffer size.

The last requirement is the hardest to implement.  Currently the
number of URBs needed to fill a buffer cannot be determined in
advance, because a buffer contains a fixed number of frames whereas
the number of frames in an URB varies to match shifts in the device's
clock rate.  To solve this problem, the patch changes the logic for
deciding how many packets an URB should contain.  Rather than using as
many as possible without exceeding an ALSA period boundary, now the
driver uses only as many packets as needed to transfer a predetermined
number of frames.  As a result, unless the device's clock has an
exceedingly variable rate, the number of URBs making up each period
(and hence each buffer) will remain constant.

The overall effect of the patch is that playback works better in
low-latency settings.  The user can still specify values for
frames/period and periods/buffer that exceed the capabilities of the
hardware, of course.  But for values that are within those
capabilities, the performance will be improved.  For example, testing
shows that a high-speed device can handle 32 frames/period and 3
periods/buffer at 48 KHz, whereas the current driver starts to get
glitchy at 64 frames/period and 2 periods/buffer.

A side effect of these changes is that the "nrpacks" module parameter
is no longer used.  The patch removes it.

ALSA : hda - not use assigned converters for all unused pins

BIOS can mark a pin as "no physical connection" if the port is used by an
integrated display which is not audio capable. And audio driver will overlook
such pins.

On Haswell, such a disconneted pin will keep muted and connected to the 1st
converter by default. But if the 1st convertor is assigned to a connected pin
for audio streaming. The muted disconnected pin can make the connected pin
no sound output.

So this patch avoids using assigned converters for all unused pins for Haswell,
including the disconected pins.

11 years agocfq: explicitly use 64bit divide operation for 64bit arguments
Anatol Pomozov [Sun, 22 Sep 2013 18:43:47 +0000 (12:43 -0600)]
cfq: explicitly use 64bit divide operation for 64bit arguments

'samples' is 64bit operant, but do_div() second parameter is 32.
do_div silently truncates high 32 bits and calculated result
is invalid.

In case if low 32bit of 'samples' are zeros then do_div() produces
kernel crash.

First round of IIO fixes for 3.12

A series of wrong 'struct dev' assumptions in suspend/resume callbacks
following on from this issue being identified in a new driver review.
One to watch out for in future.

A number of driver specific fixes
1) at91 - fix a overflow in clock rate computation
2) dummy - Kconfig dependency issue
3) isl29018 - uninitialized value
4) hmc5843 - measurement conversion bug introduced by recent cleanup.
5) ade7854-spi - wrong return value.

Some IIO core fixes
1) Wrong value picked up for event code creation for a modified channel
2) A null dereference on failure to initialize a buffer after no buffer has
   been in use, when using the available_scan_masks approach.
3) Sampling not stopped when a device is removed. Effects forced removal
   such as hot unplugging.
4) Prevent device going away if a chrdev is still open in userspace.
5) Prevent race on chardev opening and device being freed.
6) Add a missing iio_buffer_init in the call back buffer.

These last few are the first part of a set from Lars-Peter Clausen who
has been taking a closer look at our removal paths and buffer handling
than anyone has for quite some time.

block: Add nr_bios to block_rq_remap tracepoint

Adding the number of bios in a remapped request to 'block_rq_remap'
tracepoint.

Request remapper clones bios in a request to track the completion
status of each bio. So the number of bios can be useful information
for investigation.

11 years agoBtrfs: create the uuid tree on remount rw

Btrfs: create the uuid tree on remount rw

Users have been complaining of the uuid tree stuff warning that there is no uuid
root when trying to do snapshot operations.  This is because if you mount -o ro
we will not create the uuid tree.  But then if you mount -o rw,remount we will
still not create it and then any subsequent snapshot/subvol operations you try
to do will fail gloriously.  Fix this by creating the uuid_root on remount rw if
it was not already there.  Thanks,
