Its input is YUV encoded +stream and it is able to convert it to RGB.

Those entities +can scale the frames up and down and also change the YUV sampling (for example +YUV4:2:2 -> YUV4:2:0). They also have cropping capability on the sink pad. +The resizers entities can only operate on YUV:4:2:2 format +(MEDIA_BUS_FMT_YUYV8_2X8). +The mainpath capture device supports capturing video in bayer formats. In that +case the resizer of the mainpath is set to 'bypass' mode - it just forward the +frame without operating on it. + +rkisp1_isp - Image Signal Processing Subdevice Node +--------------------------------------------------- +This is the isp entity. It is connected to the sensor on sink pad 0 and +receives the frames using the CSI-2 protocol. It is responsible of configuring +the CSI-2 protocol. It has a cropping capability on sink pad 0 that is +connected to the sensor and on source pad 2 connected to the resizer entities. +Cropping on sink pad 0 defines the image region from the sensor. +Cropping on source pad 2 defines the region for the Image Stabilizer (IS). + +.. _rkisp1_stats: + +rkisp1_stats - Statistics Video Node +------------------------------------ +The statistics video node outputs the 3A (auto focus, auto exposure and auto +white balance) statistics, and also histogram statistics for the frames that +are being processed by the rkisp1 to userspace applications. +Using these data, applications can implement algorithms and re-parameterize +the driver through the rkisp_params node to improve image quality during a +video stream. +The buffer format is defined by struct :c:type:`rkisp1_stat_buffer`, and +userspace should set +:ref:`V4L2_META_FMT_RK_ISP1_STAT_3A ` as the +dataformat. + +.. _rkisp1_params: + +rkisp1_params - Parameters Video Node +------------------------------------- +The rkisp1_params video node receives a set of parameters from userspace +to be applied to the hardware during a video stream, allowing userspace +to dynamically modify values such as black level, cross talk corrections +and others. + +The buffer format is defined by struct :c:type:`rkisp1_params_cfg`, and +userspace should set +:ref:`V4L2_META_FMT_RK_ISP1_PARAMS ` as the +dataformat. + + +Capturing Video Frames Example +============================== + +In the following example, the sensor connected to pad 0 of 'rkisp1_isp' is +imx219. + +The following commands can be used to capture video from the selfpath video +node with dimension 900x800 planar format YUV 4:2:2.

So it is also configured to `SRGGB10_1X10/1640x1232`. +In addition, the rkisp1_isp:0 pad is configured to cropping `(0,0)/1600x1200`. + +The cropping dimensions are automatically propagated to be the format of the +isp source pad `rkisp1_isp:2`. Another cropping operation is configured on +the isp source pad: `(0,0)/1500x1100`. + +The resizer's sink pad `rkisp1_resizer_selfpath` should be configured to format +`YUYV8_2X8/1500x1100` in order to match the format on the other side of the +link. In addition a cropping `(300,400)/1400x1000` is configured on it. + +The source pad of the resizer, `rkisp1_resizer_selfpath:1` is configured to +format `YUYV8_2X8/900x800`. That means that the resizer first crop a window +of `(300,400)/1400x100` from the received frame and then scales this window +to dimension `900x800`. + +Note that the above example does not uses the stats-params control loop. +Therefore the capture frames will not go through the 3A algorithms and +probably won't have a good quality, and can even look dark and greenish. + +Configuring Quantization +======================== + +The driver supports limited and full range quantization on YUV formats, +where limited is the default. +To switch between one or the other, userspace should use the Colorspace +Conversion API (CSC) for subdevices on source pad 2 of the +isp (`rkisp1_isp:2`). The quantization configured on this pad is the +quantization of the captured video frames on the mainpath and selfpath +video nodes. +Note that the resizer and capture entities will always report +``V4L2_QUANTIZATION_DEFAULT`` even if the quantization is configured to full +range on `rkisp1_isp:2`. So in order to get the configured quantization, +application should get it from pad `rkisp1_isp:2`. + diff --git a/Documentation/admin-guide/media/v4l-drivers.rst b/Documentation/admin-guide/media/v4l-drivers.rst index 251cc4ede0b6..9c7ebe2ca3bd 100644 --- a/Documentation/admin-guide/media/v4l-drivers.rst +++ b/Documentation/admin-guide/media/v4l-drivers.rst @@ -25,6 +25,7 @@ Video4Linux (V4L) driver-specific documentation philips qcom_camss rcar-fdp1 + rkisp1 saa7134 si470x si4713 -- cgit v1.2.3 From b97d4a1eb4baede15e9c9503d97f81d007e493f3 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 25 Sep 2020 11:48:40 +0200 Subject: media: docs: ipu3.rst: rely at automarkup extension There are several :c:type: definitions there, in order to do cross-references with the driver's documentation.

For parameters that are configured as not enabled by the user space, the corresponding structs are ignored by the driver, in which case the existing configuration of the algorithm will be preserved. -- cgit v1.2.3 From 210191dd5314f26b062fed3a47d108a0e4f53d18 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 2 Oct 2020 14:24:07 +0200 Subject: media: siano: rename a duplicated card string There are two different variants for Hauppauge WinTV MiniCard: [SMS1XXX_BOARD_HAUPPAUGE_TIGER_MINICARD] = { .name = "Hauppauge WinTV MiniCard", .type = SMS_NOVA_B0, .fw[DEVICE_MODE_DVBT_BDA] = SMS_FW_DVBT_HCW_55XXX, .default_mode = DEVICE_MODE_DVBT_BDA, .lna_ctrl = 29, .board_cfg.foreign_lna0_ctrl = 29, .rf_switch = 17, .board_cfg.rf_switch_uhf = 17, }, [SMS1XXX_BOARD_HAUPPAUGE_TIGER_MINICARD_R2] = { .name = "Hauppauge WinTV MiniCard Rev 2", .type = SMS_NOVA_B0, .fw[DEVICE_MODE_DVBT_BDA] = SMS_FW_DVBT_HCW_55XXX, .default_mode = DEVICE_MODE_DVBT_BDA, .lna_ctrl = -1, }, As it can be seen, the RF part of the definitions are different. So, better to use different names in order to distinguish between them.
