	Take the SPDX header from the mojom file. Error out if the mojom file has no SPDX header. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>
2021-05-27	utils: ipc: Add script to extract doxygen docs from mojom files	Paul Elder
	Add a script to extract doxygen documentation comments from mojom files. It matches based on ^\/\\$ for start of block and ^ \*\/$ for end of block, and simply copies the comments to the output file along with a header and the libcamera namespace. Also add it to the meson file so it is usable by other meson files.

If the AE algorithm is locked the value shall be set to true, if it's converging it shall be set to false. If the AE algorithm is not running the control shall not be present in the metadata control list. \sa AeEnable # AeMeteringMode needs further attention: # - Auto-generate max enum value. # - Better handling of custom types. - AeMeteringMode: type: int32_t description: | Specify a metering mode for the AE algorithm to use. The metering modes determine which parts of the image are used to determine the scene brightness. Metering modes may be platform specific and not all metering modes may be supported. enum: - name: MeteringCentreWeighted value: 0 description: Centre-weighted metering mode. - name: MeteringSpot value: 1 description: Spot metering mode. - name: MeteringMatrix value: 2 description: Matrix metering mode. - name: MeteringCustom value: 3 description: Custom metering mode. - name: MeteringModeMax value: 3 description: Maximum allowed value (place any new values above here). # AeConstraintMode needs further attention: # - Auto-generate max enum value. # - Better handling of custom types. - AeConstraintMode: type: int32_t description: | Specify a constraint mode for the AE algorithm to use. These determine how the measured scene brightness is adjusted to reach the desired target exposure. Constraint modes may be platform specific, and not all constraint modes may be supported. enum: - name: ConstraintNormal value: 0 description: Default constraint mode. This mode aims to balance the exposure of different parts of the image so as to reach a reasonable average level. However, highlights in the image may appear over-exposed and lowlights may appear under-exposed. - name: ConstraintHighlight value: 1 description: Highlight constraint mode. This mode adjusts the exposure levels in order to try and avoid over-exposing the brightest parts (highlights) of an image. Other non-highlight parts of the image may appear under-exposed. - name: ConstraintShadows value: 2 description: Shadows constraint mode. This mode adjusts the exposure levels in order to try and avoid under-exposing the dark parts (shadows) of an image. Other normally exposed parts of the image may appear over-exposed. - name: ConstraintCustom value: 3 description: Custom constraint mode. - name: ConstraintModeMax value: 3 description: Maximum allowed value (place any new values above here). # AeExposureMode needs further attention: # - Auto-generate max enum value. # - Better handling of custom types. - AeExposureMode: type: int32_t description: | Specify an exposure mode for the AE algorithm to use. These specify how the desired total exposure is divided between the shutter time and the sensor's analogue gain. The exposure modes are platform specific, and not all exposure modes may be supported. enum: - name: ExposureNormal value: 0 description: Default exposure mode. - name: ExposureShort value: 1 description: Exposure mode allowing only short exposure times. - name: ExposureLong value: 2 description: Exposure mode allowing long exposure times. - name: ExposureCustom value: 3 description: Custom exposure mode. - name: ExposureModeMax value: 3 description: Maximum allowed value (place any new values above here). - ExposureValue: type: float description: | Specify an Exposure Value (EV) parameter. The EV parameter will only be applied if the AE algorithm is currently enabled. By convention EV adjusts the exposure as log2. For example EV = [-2, -1, 0.5, 0, 0.5, 1, 2] results in an exposure adjustment of [1/4x, 1/2x, 1/sqrt(2)x, 1x, sqrt(2)x, 2x, 4x]. \sa AeEnable - ExposureTime: type: int32_t description: | Exposure time (shutter speed) for the frame applied in the sensor device. This value is specified in micro-seconds. \sa AnalogueGain AeEnable - AnalogueGain: type: float description: | Analogue gain value applied in the sensor device. The value of the control specifies the gain multiplier applied to all colour channels. This value cannot be lower than 1.0. \sa ExposureTime AeEnable - Brightness: type: float description: | Specify a fixed brightness parameter. Positive values (up to 1.0) produce brighter images; negative values (up to -1.0) produce darker images and 0.0 leaves pixels unchanged. - Contrast: type: float description: | Specify a fixed contrast parameter. Normal contrast is given by the value 1.0; larger values produce images with more contrast. - Lux: type: float description: | Report an estimate of the current illuminance level in lux. The Lux control can only be returned in metadata. - AwbEnable: type: bool description: | Enable or disable the AWB. \sa ColourGains # AwbMode needs further attention: # - Auto-generate max enum value. # - Better handling of custom types. - AwbMode: type: int32_t description: | Specify the range of illuminants to use for the AWB algorithm. The modes supported are platform specific, and not all modes may be supported. enum: - name: AwbAuto value: 0 description: Search over the whole colour temperature range. - name: AwbIncandescent value: 1 description: Incandescent AWB lamp mode. - name: AwbTungsten value: 2 description: Tungsten AWB lamp mode. - name: AwbFluorescent value: 3 description: Fluorescent AWB lamp mode. - name: AwbIndoor value: 4 description: Indoor AWB lighting mode. - name: AwbDaylight value: 5 description: Daylight AWB lighting mode. - name: AwbCloudy value: 6 description: Cloudy AWB lighting mode. - name: AwbCustom value: 7 description: Custom AWB mode. - name: AwbModeMax value: 7 description: Maximum allowed value (place any new values above here). - ColourGains: type: float description: | Pair of gain values for the Red and Blue colour channels, in that order. ColourGains can only be applied in a Request when the AWB is disabled. \sa AwbEnable size: [2] - ColourTemperature: type: int32_t description: Report the current estimate of the colour temperature, in kelvin, for this frame. The ColourTemperature control can only be returned in metadata. - Saturation: type: float description: | Specify a fixed saturation parameter. Normal saturation is given by the value 1.0; larger values produce more saturated colours; 0.0 produces a greyscale image. - SensorBlackLevels: type: int32_t description: | Reports the sensor black levels used for processing a frame, in the order R, Gr, Gb, B. These values are returned as numbers out of a 16-bit pixel range (as if pixels ranged from 0 to 65535). The SensorBlackLevels control can only be returned in metadata. size: [4] - Sharpness: type: float description: | A value of 0.0 means no sharpening. The minimum value means minimal sharpening, and shall be 0.0 unless the camera can't disable sharpening completely. The default value shall give a "reasonable" level of sharpening, suitable for most use cases. The maximum value may apply extremely high levels of sharpening, higher than anyone could reasonably want. Negative values are not allowed. Note also that sharpening is not applied to raw streams. - FocusFoM: type: int32_t description: | Reports a Figure of Merit (FoM) to indicate how in-focus the frame is. A larger FocusFoM value indicates a more in-focus frame. This control depends on the IPA to gather ISP statistics from the defined focus region, and combine them in a suitable way to generate a FocusFoM value. In this respect, it is not necessarily aimed at providing a way to implement a focus algorithm by the application, rather an indication of how in-focus a frame is. - ColourCorrectionMatrix: type: float description: | The 3x3 matrix that converts camera RGB to sRGB within the imaging pipeline. This should describe the matrix that is used after pixels have been white-balanced, but before any gamma transformation. The 3x3 matrix is stored in conventional reading order in an array of 9 floating point values. size: [3x3] ...
