1168 * struct rkisp1_ext_params_block_header - RkISP1 extensible parameters block
1169 * header
1170 *
1171 * This structure represents the common part of all the ISP configuration
1172 * blocks. Each parameters block shall embed an instance of this structure type
1173 * as its first member, followed by the block-specific configuration data. The
1174 * driver inspects this common header to discern the block type and its size and
1175 * properly handle the block content by casting it to the correct block-specific
1176 * type.
1177 *
1178 * The @type field is one of the values enumerated by
1179 * :c:type:`rkisp1_ext_params_block_type` and specifies how the data should be
1180 * interpreted by the driver. The @size field specifies the size of the
1181 * parameters block and is used by the driver for validation purposes.
1182 *
1183 * The @flags field is a bitmask of per-block flags RKISP1_EXT_PARAMS_FL_*.
1184 *
1185 * When userspace wants to configure and enable an ISP block it shall fully
1186 * populate the block configuration and set the
1187 * RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE bit in the @flags field.
1188 *
1189 * When userspace simply wants to disable an ISP block the
1190 * RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bit should be set in @flags field. The
1191 * driver ignores the rest of the block configuration structure in this case.
1192 *
1193 * If a new configuration of an ISP block has to be applied userspace shall
1194 * fully populate the ISP block configuration and omit setting the
1195 * RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits
1196 * in the @flags field.
1197 *
1198 * Setting both the RKISP1_EXT_PARAMS_FL_BLOCK_ENABLE and
1199 * RKISP1_EXT_PARAMS_FL_BLOCK_DISABLE bits in the @flags field is not allowed
1200 * and not accepted by the driver.
1201 *
1202 * Userspace is responsible for correctly populating the parameters block header
1203 * fields (@type, @flags and @size) and the block-specific parameters.

1595 * struct rkisp1_ext_params_cfg - RkISP1 extensible parameters configuration
1596 *
1597 * This struct contains the configuration parameters of the RkISP1 ISP
1598 * algorithms, serialized by userspace into a data buffer. Each configuration
1599 * parameter block is represented by a block-specific structure which contains a
1600 * :c:type:`rkisp1_ext_params_block_header` entry as first member. Userspace
1601 * populates the @data buffer with configuration parameters for the blocks that
1602 * it intends to configure. As a consequence, the data buffer effective size
1603 * changes according to the number of ISP blocks that userspace intends to
1604 * configure and is set by userspace in the @data_size field.
1605 *
1606 * The parameters buffer is versioned by the @version field to allow modifying
1607 * and extending its definition. Userspace shall populate the @version field to
1608 * inform the driver about the version it intends to use. The driver will parse
1609 * and handle the @data buffer according to the data layout specific to the
1610 * indicated version and return an error if the desired version is not
1611 * supported.
1612 *
1613 * Currently the single RKISP1_EXT_PARAM_BUFFER_V1 version is supported.
1614 * When a new format version will be added, a mechanism for userspace to query
1615 * the supported format versions will be implemented in the form of a read-only
1616 * V4L2 control. If such control is not available, userspace should assume only
1617 * RKISP1_EXT_PARAM_BUFFER_V1 is supported by the driver.
1618 *
1619 * The read-only V4L2 control ``RKISP1_CID_SUPPORTED_PARAMS_BLOCKS`` can be used
1620 * to query the blocks supported by the device. It contains a bitmask where each
1621 * bit represents the availability of the corresponding entry from the
1622 * :c:type:`rkisp1_ext_params_block_type` enum. The current and default values
1623 * of the control represents the blocks supported by the device instance, while
1624 * the maximum value represents the blocks supported by the kernel driver,
1625 * independently of the device instance.
1626 *
1627 * For each ISP block that userspace wants to configure, a block-specific
1628 * structure is appended to the @data buffer, one after the other without gaps
1629 * in between nor overlaps. Userspace shall populate the @data_size field with
1630 * the effective size, in bytes, of the @data buffer.
1631 *
1632 * The expected memory layout of the parameters buffer is::
