b7df4cc3 - ALSA: misc: Use -y instead of -objs in Makefile

Tue, 07 May 2024 13:55:09 +0000

ALSA: misc: Use *-y instead of *-objs in Makefile*-objs suffix is reserved rather for (user-space) host programs whileusually *-y suffix is used for kernel drivers (although *-objs worksfor that purpose for now).Let's correct the old usages of *-objs in Makefiles.Signed-off-by: Takashi Iwai Reviewed-by: Andy Shevchenko Reviewed-by: Jaroslav Kysela Link: https://lore.kernel.org/r/20240507135513.14919-10-tiwai@suse.de List of files: /linux-6.15/sound/xen/Makefile

1cee5593 - ALSA: xen-front: Implement ALSA virtual sound driver

Mon, 14 May 2018 06:27:41 +0000

ALSA: xen-front: Implement ALSA virtual sound driverImplement essential initialization of the sound driver: - introduce required data structures - handle driver registration - handle sound card registration - register sound driver on backend connection - remove sound driver on backend disconnectInitialize virtual sound card with streams according to theXen store configuration.Implement ALSA driver operations including: - manage frontend/backend shared buffers - manage Xen bus event channel statesImplement requests from front to back for ALSAPCM operations. - report ALSA period elapsed event: handle XENSND_EVT_CUR_POS notifications from the backend when stream position advances during playback/capture. The event carries a value of how many octets were played/captured at the time of the event. - implement explicit stream parameter negotiation between backend and frontend: handle XENSND_OP_HW_PARAM_QUERY request to read/update configuration space for the parameter given: request passes desired parameter interval and the response to this request returns min/max interval for the parameter to be used.Signed-off-by: Oleksandr Andrushchenko Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/xen/Makefile

d6e0fbb8 - ALSA: xen-front: Implement handling of shared buffers

Mon, 14 May 2018 06:27:40 +0000

ALSA: xen-front: Implement handling of shared buffersImplement shared buffer handling according to thepara-virtualized sound device protocol at xen/interface/io/sndif.h: - manage buffer memory - handle granted references - handle page directories[ Fixed missing linux/kernel.h inclusion -- tiwai ]Signed-off-by: Oleksandr Andrushchenko Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/xen/Makefile

788ef64a - ALSA: xen-front: Implement Xen event channel handling

Mon, 14 May 2018 06:27:39 +0000

ALSA: xen-front: Implement Xen event channel handlingHandle Xen event channels: - create for all configured streams and publish corresponding ring references and event channels in Xen store, so backend can connect - implement event channels interrupt handlers - create and destroy event channels with respect to Xen bus stateSigned-off-by: Oleksandr Andrushchenko Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/xen/Makefile

fd3b3604 - ALSA: xen-front: Read sound driver configuration from Xen store

Mon, 14 May 2018 06:27:38 +0000

ALSA: xen-front: Read sound driver configuration from Xen storeRead configuration values from Xen store accordingto xen/interface/io/sndif.h protocol: - introduce configuration structures for different components, e.g. sound card, device, stream - read PCM HW parameters, e.g rate, format etc. - detect stream type (capture/playback) - read device and card parametersSigned-off-by: Oleksandr Andrushchenko Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/xen/Makefile
