V4L2_CID_VBLANK is set by userspace. It can be updated by drivers when the format and/or selection rectangles are modified, but will not otherwise be changed automatically at runtime. The IPA should compute the desired vblank value and pass it to the pipeline handler to configure the sensor. I don't think that's related to the work that JM is doing. > >> > >> IPU3Action op; > >> op.op = ActionMetadataReady;

Ok, I will check in with JM for that, Meanwhile, I saw and JM also mentioned that, for getting the vblank - we need 'frameIntegrationDiff' (referencing CamHelper::GetVBlanking from RPi IPA). Looking into it, it's seems to a value tied to a particular sensor, so that's something. Not sure if we are going to put in some specific sensor-related parameters into IPU3 IPA. CC-ing JM, Would like your thoughts on the above discussion. > >>>> >>>> IPU3Action op; >>>> op.op = ActionMetadataReady;

This decision is down to the AGC and what exposure it decides to use. This is also where we run into the problem with V4L2 control limits not allowing us to update VBLANK and EXPOSURE at the same time without using priority writes.

We will, Jean-Michel is working on that. The frame integration diff value will be used by the IPA to compute the desired exposure time and/or vertical blanking, but you won't need to care about it to compute the frame duration. Only the vblank value is needed for that. > CC-ing JM, Would like your thoughts on the above discussion. > > >>>> > >>>> IPU3Action op; > >>>> op.op = ActionMetadataReady;

Yes, the vblank value is needed and currently I am using the minimum vblank value queried from sensor controls in the " ipa: ipu3: Calculate frame duration from minimum VBLANK value" patch. It also contains the \todo stating that it can be improved on, by using vblank from each frame's exposure.

We report a hard-coded frame duration value for CTS. However, when the CTS is tested on nautilus, which has a 'imx258' sensor, the frame duration was found to be out-of-range. Since different sensors have different frame durations range-limits, we need to bump up our value to match the lower end of the 'imx258' frame duration range-limit (rounded up to the nearest micro-second). This allows the following CTS test to pass on nautilus platform: - android.hardware.camera2.cts.CaptureRequestTest#testNoiseReductionModeControl Signed-off-by: Umang Jain <umang.jain@ideasonboard.com> --- src/ipa/ipu3/ipu3.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
