Hi Ondrej, (CC'ing Paul and Umang) Thank you for the patch.

It's also a limit from the datasheet, so the change should not be that controversial: https://megous.com/dl/tmp/d2b333043ecebaf3.png (so that it doesn't sound like I just copied the BSP values) regards, o. > > Signed-off-by: Ondrej Jirman <megi@xff.cz> > > --- > > drivers/media/platform/rockchip/rkisp1/rkisp1-common.h | 4 ++-- > > 1 file changed, 2 insertions(+), 2 deletions(-) > > > > diff --git a/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h b/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h > > index 4b6b28c05b89..74098ddbeeb3 100644 > > --- a/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h > > +++ b/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h > > @@ -33,8 +33,8 @@ struct dentry; > > #define RKISP1_ISP_SD_SINK BIT(1) > > > > /* min and max values for the widths and heights of the entities */ > > -#define RKISP1_ISP_MAX_WIDTH 4032 > > -#define RKISP1_ISP_MAX_HEIGHT 3024 > > +#define RKISP1_ISP_MAX_WIDTH 4416 > > +#define RKISP1_ISP_MAX_HEIGHT 3312 > > #define RKISP1_ISP_MIN_WIDTH 32 > > #define RKISP1_ISP_MIN_HEIGHT 32 > > > > -- > Regards, > > Laurent Pinchart

Here's what I have in my notes: - The RK3399 TRM says 4416x3312 max input and output on main path, with 1920x1080 max output on self path. - The PX30 datasheet [1] says 3264x2448 max input and output on main path, with 1920x1080 max output on self path. - The RK3288 documentation [2] (under "Camera Interface and Image Processor") says 4416x3312 max input and output on main path, with 1920x1080 max output on self path. - The i.MX8MP reference manual (the open one) [3] (in table 13-1) says 4096x3072 max resolution in single ISP mode The i.MX8M Plus seems to indeed be limited to 4096x3072, but the TPG is capable of generating 4416x3312, and the ISP works fine in bypass (and therefore raw) mode, so technically it has different maximum sizes depending on the format which makes this more exciting. In any case, the PX30 (assuming the datasheet is correct) only supports up to 3264x2448, so the existing #define is incorrect anyway. I don't have a PX30 nor an RK3288 so I can't test those, and I haven't set up my OV64A40 yet which (I've heard) can be used to test even bigger resolutions.

Something like this? https://lore.kernel.org/lkml/20240220235720.3010608-1-megi@xff.cz/T/#u Only the first two SoCs are supported by rkisp1 driver upstream, yet. So I only have to deal with input and mainpath maximum ATM. So the patch is rather simple. kind regards, o. > > [1] https://opensource.rock-chips.com/images/8/87/Rockchip_PX30_Datasheet_V1.4-20191227.pdf > > [2] https://opensource.rock-chips.com/images/4/49/Rockchip_RK3288_Datasheet_V2.7-20191227.pdf > > [3] (requires login) https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-8-applications-processors/i-mx-8m-plus-arm-cortex-a53-machine-learning-vision-multimedia-and-industrial-iot:IMX8MPLUS > > > > > > > > > Signed-off-by: Ondrej Jirman <megi@xff.cz> > > > > > > > --- > > > > > > > drivers/media/platform/rockchip/rkisp1/rkisp1-common.h | 4 ++-- > > > > > > > 1 file changed, 2 insertions(+), 2 deletions(-) > > > > > > > > > > > > > > diff --git a/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h b/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h > > > > > > > index 4b6b28c05b89..74098ddbeeb3 100644 > > > > > > > --- a/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h > > > > > > > +++ b/drivers/media/platform/rockchip/rkisp1/rkisp1-common.h > > > > > > > @@ -33,8 +33,8 @@ struct dentry; > > > > > > > #define RKISP1_ISP_SD_SINK BIT(1) > > > > > > > > > > > > > > /* min and max values for the widths and heights of the entities */ > > > > > > > -#define RKISP1_ISP_MAX_WIDTH 4032 > > > > > > > -#define RKISP1_ISP_MAX_HEIGHT 3024 > > > > > > > +#define RKISP1_ISP_MAX_WIDTH 4416 > > > > > > > +#define RKISP1_ISP_MAX_HEIGHT 3312 > > > > > > > #define RKISP1_ISP_MIN_WIDTH 32 > > > > > > > #define RKISP1_ISP_MIN_HEIGHT 32 > > > > > > > > > -- > Regards, > > Laurent Pinchart
