Userland access goes via /dev/cmt_speech. The API is implemented in libcmtspeechdata, which is used by ofono and the freesmartphone.org project. Apart from that the device is also used by the phone binaries distributed with Maemo. So while this is a new userland ABI for the mainline kernel it has been tested in the wild for some years. Simple Testing of the API can be done by checking out libcmtspeechdata [0], building the test tool and executing it. The tool will loop back audio data received from the caller. I have prepared a kernel branch for this patchset, which can be found at [1]. Changes since PATCHv1 [2]: * Squash cmt-speech patches together * cs_alloc_cmds(): GFP_ATOMIC -> GFP_KERNEL * CS_SET_WAKELINE ioctl: Add sanity check [0] https://lkml.org/lkml/2015/2/11/526 [1] git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-hsi.git branch/cmt-speech-2 [2] https://lkml.org/lkml/2015/3/1/282 -- Sebastian Kai Vehmanen (1): HSI: cmt_speech: Add cmt-speech driver Sebastian Reichel (1): HSI: nokia-modem: Add cmt-speech support drivers/hsi/clients/Kconfig | 11 +- drivers/hsi/clients/Makefile | 1 + drivers/hsi/clients/cmt_speech.c | 1457 ++++++++++++++++++++++++++++++++++ drivers/hsi/clients/nokia-modem.c | 31 +- include/uapi/linux/hsi/Kbuild | 2 +- include/uapi/linux/hsi/cs-protocol.h | 113 +++ 6 files changed, 1612 insertions(+), 3 deletions(-) create mode 100644 drivers/hsi/clients/cmt_speech.c create mode 100644 include/uapi/linux/hsi/cs-protocol.h -- 2.1.4
