2014-11-22ALSA: asihpi: Add support for stream interrupt.Eliot Blennerhassett
Some cards have a so-called low-latency mode, in which they present a single multichannel stream with no mixing or samplerate conversion. In this mode the card can generate an interrupt per internal processing block (typically 32 or 64 frames) Signed-off-by: Eliot Blennerhassett <eliot@blennerhassett.gen.nz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-12-22ALSA: asihpi - Remove redundant struct members.Eliot Blennerhassett
Structs hpi_adapter and snd_card_asihpi had members that duplicate those in underlying hpi_adapter_obj or whose info can be retrieved using hpi_adapter_get_info(). Print less info in probe function, it can be retrieved from /proc. Avoid name redundancy: hpi_adapter_obj.adapter_type renamed to .type Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-07-22ALSA: asihpi - DSP code loader API now independent of OSEliot Blennerhassett
The loader API has been revised so that OS specific data is kept local to hpidspcd.c, and the public API is unchanged across OSes. Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

code Some cobranet control data would not fit in an original HPI message. Now that HPI is able to transfer larger messages, this special handling is no longer required. Signed-off-by: Eliot Blennerhassett <eblennerhassett@audioscience.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2011-02-10ALSA: asihpi - Remove int flag polling code preparing for stream interrupts.Eliot Blennerhassett

2010-11-02ALSA: asihpi - Unsafe memory management when allocating control cacheJesper Juhl
I noticed that sound/pci/asihpi/hpicmn.c::hpi_alloc_control_cache() does not check the return value from kmalloc(), which may fail. If kmalloc() fails we'll dereference a null pointer and things will go bad fast. There are two memory allocations in that function and there's also the problem that the first may succeed and the second may fail and nothing is done about that either which will also go wrong down the line.

2010-05-17ALSA: sound/pci/asihpi: Use kzallocJulia Lawall
Use kzalloc rather than the combination of kmalloc and memset.
