Changes implementation of INSN_CONFIG_GET_CMD_TIMING_CONSTRAINTS for ni_mio devices to scale the result by the number of channels being used. The user is already required to indicate which channels (and how many obviously) are intended to be used. There is no point of not using this information--the analog input cards already similarly scale the timing results based on the number of channels. Signed-off-by: Spencer E. Olson <olsonse@xxxxxxxxx> --- This patch is made in reference to the last set of patches adding the timing constraint facility in pci_mio_common (51fd3673838396844f15de0e906be5333bfbbc8d). drivers/staging/comedi/drivers/ni_mio_common.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/staging/comedi/drivers/ni_mio_common.c b/drivers/staging/comedi/drivers/ni_mio_common.c index 2d1e0325d04d..5edf59ac6706 100644 --- a/drivers/staging/comedi/drivers/ni_mio_common.c +++ b/drivers/staging/comedi/drivers/ni_mio_common.c @@ -2843,7 +2843,8 @@ static int ni_ao_insn_config(struct comedi_device *dev, return ni_ao_arm(dev, s); case INSN_CONFIG_GET_CMD_TIMING_CONSTRAINTS: /* we don't care about actual channels */ - data[1] = board->ao_speed; + /* data[3] : chanlist_len */ + data[1] = board->ao_speed * data[3]; data[2] = 0; return 0; default: -- 2.17.1 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
