The register access errors are really only being paid attention to during s_power() when loading the initial register set, which is enough at least to catch a non-existent chip or basic i2c bus or other hardware issues. But I should work on catching all access errors. This is something I did in an earlier rev but I used a questionable short-cut to make it easier to implement. I'll just have to catch every case one by one. > <snip> > >> + >> +static int ov5640_s_ctrl(struct v4l2_ctrl *ctrl) >> +{ >> + struct v4l2_subdev *sd = ctrl_to_sd(ctrl); >> + struct ov5640_dev *sensor = to_ov5640_dev(sd); >> + int ret = 0; >> + >> + mutex_lock(&sensor->lock); > Could you use the same lock for the controls as you use for the rest?

Please remove the check. It's incremented by media_pipeline_start(), even if the entity is already a member of the given pipeline. I added this check because in imx-media, the ov5640 can be streaming concurrently to multiple video capture devices, and each capture device calls media_pipeline_start() at stream on, which increments the entity stream count. So if one capture device issues a stream off while others are still streaming, ov5640 should remain at stream on. So the entity stream count is being used as a streaming usage counter. Is there a better way to do this? Should I use a private stream use counter instead? > <snip> > >> + >> +free_ctrls: >> + v4l2_ctrl_handler_free(&sensor->ctrls.handler); >> +entity_cleanup: >> + mutex_destroy(&sensor->lock); >> + media_entity_cleanup(&sensor->sd.entity); >> + regulator_bulk_disable(OV5640_NUM_SUPPLIES, sensor->supplies); > Should this still be here? > >> + return ret; >> +} >> + >> +static int ov5640_remove(struct i2c_client *client) >> +{ >> + struct v4l2_subdev *sd = i2c_get_clientdata(client); >> + struct ov5640_dev *sensor = to_ov5640_dev(sd); >> + >> + regulator_bulk_disable(OV5640_NUM_SUPPLIES, sensor->supplies); > Ditto.

Different drivers may use media_pipeline_start() in different ways. Stream control shouldn't depend on that count. This could cause issues in using the driver with other ISP / receiver drivers. I think it should be enough to move the check to the imx driver in this case. > > > > ><snip> > > > >>+ > >>+free_ctrls: > >>+ v4l2_ctrl_handler_free(&sensor->ctrls.handler); > >>+entity_cleanup: > >>+ mutex_destroy(&sensor->lock); > >>+ media_entity_cleanup(&sensor->sd.entity); > >>+ regulator_bulk_disable(OV5640_NUM_SUPPLIES, sensor->supplies); > >Should this still be here? > > > >>+ return ret; > >>+} > >>+ > >>+static int ov5640_remove(struct i2c_client *client) > >>+{ > >>+ struct v4l2_subdev *sd = i2c_get_clientdata(client); > >>+ struct ov5640_dev *sensor = to_ov5640_dev(sd); > >>+ > >>+ regulator_bulk_disable(OV5640_NUM_SUPPLIES, sensor->supplies); > >Ditto. > > I don't understand. regulator_bulk_disable() is still needed, am I missing > something? You still need to enable it first. I don't see that being done in probe. As the driver implements the s_power() op, I don't see a need for powering the device on at probe time (and conversely off at remove time).

Yes, but it's quite a bit of work. It makes sense to use a static virtual channel for now.

Yes. OTOH V4L2_CID_EXPOSURE has no defined unit, so it's a better fit IMO. Way more drivers appear to be using EXPOSURE than EXPOSURE_ABSOLUTE, too. Ideally we should have only one control for exposure.

No. N-o. No no no. NO! No. N-o. NONONO. No. NooooooooooOOO!!!!!!!!!!!!! Sorry, no. Userspace needs to know exposure times. It is not so important for a webcam, but it is mandatory for digital camera. As it gets darker, autogain wants to scale exposure to cca 1/100 sec, then it wants to scale gain up to maximum, and only then it wants to continue scaling exposure. (Threshold will be shorter in "sports" mode, perhaps 1/300sec?) Plus, we want user to be able to manually set exposure parameters. So... _this_ driver probably should use V4L2_CID_EXPOSURE. (If the units are not known). But in general we'd prefer drivers using V4L2_CID_EXPOSURE_ABSOLUTE. Your car has speedometer calibrated in km/h or mph, not in "% of max", right? Pavel

Oh you're right, it must have been left over from a previous revision I guess. Yes, regulator_bulk_enable|disable() is only called in ov5640_set_power(). I'll remove regulator_bulk_disable() from probe/remove. Steve

Actually no. The CSI2IPU gasket in i.MX6 quad sends virtual channel 0 streams to IPU1-CSI0. But input to IPU1-CSI0 is also muxed with parallel bus cameras. So if vc0 were chosen instead, platforms that support parallel cameras to IPU1-CSI0 (SabreLite, SabreSD) would not be able to use them concurrently with a MIPI CSI-2 source to IPU1-CSI1. So I prefer to use static channel 1 to support those platforms. I could convert this to a module parameter however, until a virtual channel selection subdev API becomes available, at which point that would have to be stripped. > >> >>> +/* >>> + * image size under 1280 * 960 are SUBSAMPLING >> >> -> Image >> >>> + * image size upper 1280 * 960 are SCALING >> >> above? >> done. >>> +/* >>> + * FIXME: all of these register tables are likely filled with >>> + * entries that set the register to their power-on default values, >>> + * and which are otherwise not touched by this driver.

That's a lot of work, and risky work at that. If someone could take this on (strip out power-on default values from the tables), I'd be grateful, but I don't have the time.

Steve: what's the unit in this case? Is it lines or something else? Pavel: we do need to make sure the user space will be able to know the unit, too. It's rather a case with a number of controls: the unit is known but there's no API to convey it to the user. The exposure is a bit special, too: granularity matters a lot on small values. On most other controls it does not.

On most other controls it does not. Yeah. Basically problem with exposure is that the control is logarithmic; by using linear scale we got too much resolution at long times and too little resolution at short times. (Plus, 100 usec ... n900 can do times _way_ shorter than that.) Anyway, even u32 gives us enough range, but I so the linear/log confusion does not matter. But it would be nicer if values were in 10 usec or usec, not 100 usec... Pavel

Yes, the register interface for exposure takes lines*16. Maybe converting from seconds to lines is as simple as framerate * height * seconds. But I'm not sure about that.

The lock in 'struct v4l2_ctrl_handler' can be overridden by a caller's own lock. Yes that's a good idea, I'll do that. Steve

But I'm not sure about that. The smiapp and a few other drivers are using lines. One option could be to use lines as the unit and have step as 16. Then the hblank + vblank controls will be needed, too, to enable the user to at least figure out the conversion to Si units.
