* Set the length of isochronous transfers as the sum of the frames lengths.mpi2015-06-151-11/+7
| | | | | | | | | | | | This reduces differences between non-isoch and isoch transfers submissions, makes the generic DMA buffer overrun check work with isoch transfers and will allow some code simplifications in HC drivers. Since short-transfers were never checked for isoch transfers, we now need to pass the USBD_SHORT_XFER_OK flag to not change this behavior. This might be revisited later. ok ratchov@
* Remove all audio format conversion code from the kernel (btw holdingratchov2015-05-111-7/+1

* Introduce a global interrupt-aware mutex protecting dataratchov2013-05-151-7/+6
| | | | | | | | | | | | | structures (including sound-card registers) from concurent access by syscall and interrupt code-paths. Since critical sections remain the same, calls to splraise/spllower can be safely replaced by calls to mtx_enter/mtx_leave with two exceptions: (1) mutexes are not reentrant (the inner splraise is thus removed), and (2) we're not allowed to sleep with a mutex (either msleep is used or the mutex is released before sleeping). ok and help from kettenis, a lot of work from armani

* bring back changes in uaudio.c r1.83, this time remembering to commitjakemsr2010-07-231-65/+230
| | | | | | | | | | | | | | | | | | | | | | | | | | uaudioreg.h. sorry about that. sync endpoints allow for the sample clock on USB audio devices to not be synchronized to the USB clock. the sync endpoint gives information on how much data to send to the data endpoint. although devices that require sync endpoints will "work" when the sync endpoint inormation is ignored, there is a possibility of static, echoing, or any other type of clock desync error. requires some small changes to existing code: * tighten up checks for whether a setting needs/supplies a sync endpoint. ignore settings that need a sync endpoint but don't supply one. previously all settings that require a sync endpoint were ignored. * if a sync endpoint is being used, use the same denominator for fractional samples as the sync endpoint uses (2**16). this only implements playback sync endpoints. recording sync endpoints are an odd concept: the driver would control the clock rate of the device. there may be such devices, but I can't even imagine how that could be reliably implemented. I guess you would sync to the USB clock or the system clock ... but then, what's the point?

* add a couple quirks for the E-MU 0202jakemsr2010-07-211-4/+39
| | | | | | | | | * the clock rate is configured through the audio interface, instead of on the endpoint. * since the clock rate is set on the interface, both play and record must use the same sample rate. this means the playback and recording parameters are not independent, which is what uaudio assumes.
* * check that the bytes per frame the device is reporting isn't ajakemsr2010-07-211-6/+7
| | | | | ridiculous value. * encoding expansion factor is always 1.
* move use_maxpkt out of struct chan, use a local variable in thejakemsr2010-07-211-8/+6
| | | | only function that was using it.
* some bits for USB 2.0 playback support. I'm not 100% sure aboutjakemsr2010-07-211-4/+23
| | | | | | | | scaling the frame rate to the polling interval, but it works on the E-MU 0202 and it generally makes a lot of sense, especially considering that this often brings the frames rate back to 1 kHz, which is the frame rate of USB 1.x, which was the most current USB spec when USB audio 1.0 spec was written.
* currently we use the endpoint's maximum packet size for recording,jakemsr2010-07-211-21/+48
| | | | | | | | | | | | | | | | | | | | and for playback, we use a packet size that is at least one audio frame smaller. in most usb audio devices, the sample clock is synced to the usb clock. this means that for sample rates that aren't multiples of 1000, we'll occasionally need to add a frame to adjust the overall rate. that's why we use the smaller packet size. also, the usb audio spec defines a way for devices to request to always use the maximum packet size. so, * add a max_bytes_per_frame, which is the largest packet size the channel will use. use that instead of calculating what the maximum we will use is in a couple places. generally makes things easier to understand. * respect a device's request to always use maximum packet size.
* support 24-bit encodings. simplify the way supported encodings arejakemsr2010-07-201-190/+154
| | | | | | | | | | | handled by storing an array of supported encodings. NOTE: this also removes all conversions from this driver. in particular, uaudio no longer supports 16-bit big endian encodings, because the USB audio specification only supports little endian encodings. ok ratchov
* * don't round blocksize to multiples of 16; can cause problems whenjakemsr2010-07-191-5/+2
| | | | | | | | sample size or number of channels is not a power of 2. * use 'param->bps' instead of 'param->precision / NBBY' for the number of bytes per sample. ok ratchov
* add a quirk to allow attaching devices which claim to have a vendorjakemsr2010-07-191-8/+22
| | | | | | | defined interface class, but are audio class compliant enough to be supported by this driver. the E-MU 0202 USB is such a device. this gets it attaching, but needs some forthcoming commits to make it usable.

| | | | ok krw
* add two new members to structs audio_encoding and audio_prinfo.jakemsr2010-07-151-9/+21
| | | | | | | | | | for both structs, the new members are 'bps' and 'msb', which describe the number of bytes per sample and data alignment in the sample, respectively. drivers must properly set these fields in the 'query_encoding', 'set_parameters' and 'get_default_params' hardware interface methods. discussed with ratchov, deraadt
* calculate the number of frames per usb xfer only once, and take intojakemsr2009-12-041-9/+5
| | | | | | account possible "fractional samples" which occur when the usb frame rate is not a whole number factor of the audio sample rate, such as with 44.1 kHz audio sample rate and full-speed usb (1 kHz frame rate).
