HP20020108 fixed handling of "large" read()
|
| 17 |
|
|
HP20020116 towards REV 1.5 support, based on ALSA's card-rme9652.c
|
| 18 |
|
|
HP20020118 made mixer ioctl and handling of devices>1 more safe
|
| 19 |
|
|
HP20020201 fixed handling of "large" read() properly
|
| 20 |
|
|
added REV 1.5 S/P-DIF receiver support
|
| 21 |
|
|
SNDCTL_DSP_SPEED now returns the actual speed

TODO:
|
| 24 |
|
|
- test more than one card --- done
|
| 25 |
|
|
- check for pci IOREGION (see es1370) in rme96xx_probe ??
|
| 26 |
|
|
- error detection
|
| 27 |
|
|
- mmap interface
|
| 28 |
|
|
- mixer mmap interface
|
| 29 |
|
|
- mixer ioctl
|
| 30 |
|
|
- get rid of noise upon first open (why ??)
|
| 31 |
|
|
- allow multiple open (at least for read)
|
| 32 |
|
|
- allow multiple open for non overlapping regions
|
| 33 |
|
|
- recheck the multiple devices part (offsets of different devices, etc)
|
| 34 |
|
|
- do decent draining in _release --- done
|
| 35 |
|
|
- SMP support
|
| 36 |
|
|
- what about using fragstotal>2 for small fragsize? (HP20020118)
|
| 37 |
|
|
- add support for AFMT_S32_LE
