1090 * struct rkisp1_ext_params_block_header - RkISP1 extensible parameters block
1091 * header
1092 *
1093 * This structure represents the common part of all the ISP configuration
1094 * blocks. Each parameters block shall embed an instance of this structure type
1095 * as its first member, followed by the block-specific configuration data. The
1096 * driver inspects this common header to discern the block type and its size and
1097 * properly handle the block content by casting it to the correct block-specific
1098 * type.
1099 *
1100 * The @type field is one of the values enumerated by
1101 * :c:type:`rkisp1_ext_params_block_type` and specifies how the data should be
1102 * interpreted by the driver. The @size field specifies the size of the
1103 * parameters block and is used by the driver for validation purposes.
1104 *
1105 * The @flags field is a bitmask of per-block flags RKISP1_EXT_PARAMS_FL_*.
1106 *
1107 * When userspace wants to configure and enable an ISP block it shall fully
1108 * populate the block configuration and set the
1109 * RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE bit in the @flags field.
1110 *
1111 * When userspace simply wants to disable an ISP block the
1112 * RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bit should be set in @flags field. The
1113 * driver ignores the rest of the block configuration structure in this case.
1114 *
1115 * If a new configuration of an ISP block has to be applied userspace shall
1116 * fully populate the ISP block configuration and omit setting the
1117 * RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits
1118 * in the @flags field.
1119 *
1120 * Setting both the RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and
1121 * RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits in the @flags field is not allowed
1122 * and not accepted by the driver.
1123 *
1124 * Userspace is responsible for correctly populating the parameters block header
1125 * fields (@type, @flags and @size) and the block-specific parameters.
1126 *
1127 * For example:
1128 *
1129 * .. code-block:: c
1130 *
1131 * void populate_bls(struct rkisp1_ext_params_block_header *block) {
1132 * struct rkisp1_ext_params_bls_config *bls =
1133 * (struct rkisp1_ext_params_bls_config *)block;
1134 *
1135 * bls->header.type = RKISP1_EXT_PARAMS_BLOCK_ID_BLS;
1136 * bls->header.flags = RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE;
1137 * bls->header.size = sizeof(*bls);

1501 * This struct contains the configuration parameters of the RkISP1 ISP

1503 * parameter block is represented by a block-specific structure which contains a
1504 * :c:type:`rkisp1_ext_params_block_header` entry as first member. Userspace
1505 * populates the @data buffer with configuration parameters for the blocks that

1507 * changes according to the number of ISP blocks that userspace intends to
1508 * configure and is set by userspace in the @data_size field.
1509 *
1510 * The parameters buffer is versioned by the @version field to allow modifying
1511 * and extending its definition. Userspace shall populate the @version field to
1512 * inform the driver about the version it intends to use. The driver will parse
1513 * and handle the @data buffer according to the data layout specific to the
1514 * indicated version and return an error if the desired version is not
1515 * supported.
1516 *
1517 * Currently the single RKISP1_EXT_PARAM_BUFFER_V1 version is supported.
1518 * When a new format version will be added, a mechanism for userspace to query
1519 * the supported format versions will be implemented in the form of a read-only
1520 * V4L2 control. If such control is not available, userspace should assume only
1521 * RKISP1_EXT_PARAM_BUFFER_V1 is supported by the driver.
1522 *
1523 * For each ISP block that userspace wants to configure, a block-specific
1524 * structure is appended to the @data buffer, one after the other without gaps
1525 * in between nor overlaps. Userspace shall populate the @data_size field with
1526 * the effective size, in bytes, of the @data buffer.
