      ALSA: hda - Make CONFIG_SND_HDA_CODEC_* tristate · 595fe1b7
      Takashi Iwai authored 
      So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to
historical reasons.  The major reason was that the automatic codec
driver probing wouldn't work if user sets a codec driver as a module
while the controller driver as a built-in.  And, another reason was to
avoid exporting symbols of the helper codes when all drivers are built
in.

But, this sort of "kindness" rather confuses people in the end,
especially makes the config refinement via localmodconfig unhappy.
Also, a codec module would still work if you re-bind the controller
driver via sysfs (although it's no automatic loading), so there might
be a slight use case.

That said, better to let people fallen into a pitfall than being too
smart and restrict something.  Let's make things straightforward: now
all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported
unconditionally.

      ALSA: hda - Add static DAC/pin mapping for AD1986A codec · 3690739b
      Takashi Iwai authored 
      AD1986A codec is a pretty old codec and has really many hidden
restrictions.  One of such is that each DAC is dedicated to certain
pin although there are possible connections.  Currently, the generic
parser tries to assign individual DACs as much as possible, and this
lead to two bad situations: connections where the sound actually
doesn't work, and connections conflicting other channels.

We may fix this by trying to find the best connections more harder,
but as of now, it's easier to give some hints for paired DAC/pin
connections and honor them if available, since such a hint is needed
only for specific codecs (right now only AD1986A, and there will be
unlikely any others in future).

      ALSA: hda - hdmi: Fix IEC958 ctl indexes for some simple HDMI devices · c9a6338a
      Anssi Hannula authored 
      In case a single HDA card has both HDMI and S/PDIF outputs, the S/PDIF
outputs will have their IEC958 controls created starting from index 16
and the HDMI controls will be created starting from index 0.

However, HDMI simple_playback_build_controls() as used by old VIA and
NVIDIA codecs incorrectly requests the IEC958 controls to be created
with an S/PDIF type instead of HDMI.
In case the card has other codecs that have HDMI outputs, the controls
will be created with wrong index=16, causing them to e.g. be unreachable
by the ALSA "hdmi" alias.

Fix that by making simple_playback_build_controls() request controls
with HDMI indexes.

Not many cards have an affected configuration, but e.g. ASUS M3N78-VM
contains an integrated NVIDIA HDA "card" with:
- a VIA codec that has, among others, an S/PDIF pin incorrectly
  labelled as an HDMI pin, and
- an NVIDIA MCP7x HDMI codec.

      ALSA: atmel_abdac: clk_round_rate() can return a zero upon error · 337bb336
      Paul Walmsley authored 
      Treat both negative and zero return values from clk_round_rate()
as errors.  This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather
than a signed type, since some clock sources can generate rates higher
than (2^31)-1 Hz.

Eventually, when calling clk_round_rate(), only a return value of
zero will be considered a error; all other values will be
considered valid rates.  The comparison against values less than
0 is kept to preserve the correct behavior in the meantime.

      Not all channels have been initialized, so far, especially when aamix
NID itself doesn't have amps but its leaves have.  This patch fixes
these holes.  Otherwise you might get unexpected loopback inputs,
e.g. from surround channels.

      ALSA: compress: Fix 64bit ABI incompatibility · 6733cf57
      Takashi Iwai authored 
      snd_pcm_uframes_t is defined as unsigned long so it would take
different sizes depending on 32 or 64bit architectures.  As we don't
want this ABI incompatibility, and there is no real 64bit user yet,
let's make it the fixed size with __u32.

Also bump the protocol version number to 0.1.2.

      ALSA: memalloc.h - fix wrong truncation of dma_addr_t · 932e9dec
      Stefano Panella authored 
      When running a 32bit kernel the hda_intel driver is still reporting
a 64bit dma_mask if the HW supports it.

From sound/pci/hda/hda_intel.c:

        /* allow 64bit DMA address if supported by H/W */
        if ((gcap & ICH6_GCAP_64OK) && !pci_set_dma_mask(pci, DMA_BIT_MASK(64)))
                pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(64));
        else {
                pci_set_dma_mask(pci, DMA_BIT_MASK(32));
                pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(32));
        }

which means when there is a call to dma_alloc_coherent from
snd_malloc_dev_pages a machine address bigger than 32bit can be returned.
This can be true in particular if running  the 32bit kernel as a pv dom0
under the Xen Hypervisor or PAE on bare metal.

The problem is that when calling setup_bdle to program the BLE the
dma_addr_t returned from the dma_alloc_coherent is wrongly truncated
from snd_sgbuf_get_addr if running a 32bit kernel:

static inline dma_addr_t snd_sgbuf_get_addr(struct snd_dma_buffer *dmab,
                                           size_t offset)
{
        struct snd_sg_buf *sgbuf = dmab->private_data;
        dma_addr_t addr = sgbuf->table[offset >> PAGE_SHIFT].addr;
        addr &= PAGE_MASK;
        return addr + offset % PAGE_SIZE;
}

where PAGE_MASK in a 32bit kernel is zeroing the upper 32bit af addr.

Without this patch the HW will fetch the 32bit truncated address,
which is not the one obtained from dma_alloc_coherent and will result
to a non working audio but can corrupt host memory at a random location.

The current patch apply to v3.13-rc3-74-g6c843f5
