The goal here is to filter out sensor resolutions which cannot be supported on the ISP. And return the resolution which is equal to or just less than the max ISP input. The notion was brought up in v1 of the patch here: https://patchwork.libcamera.org/patch/19411/#28485 which I agreed (it was never addressed until this patch). ``` Should `resolution` be replaced by the maximum sensor resolution smaller than the isp max input size (maybe computed in populateFormats() ? ) ``` For example, the platform I'm working with has imx283 and imx335 working with following sizes (in decreasing order of resolution): IMX283: { 5472x3648, 4096x3072, 2736x1824 ...} IMX335: { 2592x1944, ... } So the function should filter out 5472x3648 for IMX283 which is higher than maxIspInputSize_ and return 4096x3072 For imx335, it returns 2592x1944 because that's the highest resolution here and the ISP shall support it. >> + for (auto &sz : sizes) { >> + if (sz <= ispMaxInputSize_ && sz > sensorResolution) > I don't think this is right, see how the comparison operator is defined > for the Size class. Ah, you are correct here.

As I have explained briefly above, it varies with the sensor - similarly how sensor->resolution() varies which has been replaced with maxSupportedSensorResolution() here. >> + if (resolution.isNull()) { >> + LOG(RkISP1, Error) << "No suitable format/resolution found" >> + << "for ISP input"; >> + return {}; >> + } >> >> /* Min and max resolutions to populate the available stream formats. */ >> Size maxResolution = maxResolution_.boundedToAspectRatio(resolution) >> @@ -220,7 +242,12 @@ CameraConfiguration::Status RkISP1Path::validate(const CameraSensor *sensor, >> StreamConfiguration *cfg) >> { >> const std::vector<unsigned int> &mbusCodes = sensor->mbusCodes(); >> - const Size &resolution = sensor->resolution(); >> + Size resolution = maxSupportedSensorResolution(sensor); > And validated too. > > And furthermore, the maximum supported sensor resolution should be the > same for both paths, shouldn't it ? Do you mean here main and self paths here? It's probably be a guess at this time, I will have to check if there is some restriction when main and self paths are used simultaneously - and whether it affects the ISP input size. > Overall this patch feels a bit too much of a hack for me to be > comfortable with it. Ok - I think I started out with v1 (had two R-b tags already) and only made improvement (maxSupportedSensorResolution()) which was also a review comment on the series.
