Macro Definition Documentation

#define ADV_CONFIG_INIT	(		cfg,
			ctx
	)

Value:

do { \
            memset(&cfg, 0, sizeof(cfg)); \
            cfg.clientContext = (void *)(ctx); \
        } while (0)

Macro to initialize NvMediaISCAdvancedConfig parameter.

Clears the parameter and updates with the NvMediaISCAdvancedConfig::clientContext pointer.

Parameters

[in]	cfg	The configuration to initialize.
[in]	ctx	The clientContext pointer to be updated.

#define ISC_RDEV_CFG	(		csi,
			i2c
	)		(((uint32_t)(csi) << RDEV_CFG_I2C_BITS) | (i2c))

Macro to create root device configuration to generate the configuration of the root device by its connected CSI port and I2C bus.

Parameters

[in]	csi	The CSI port number defined in NvMediaICPInterfaceType.
[in]	i2c	The I2C bus number defined in NvMediaISC_I2CPort.

Definition at line 71 of file nvmedia_isc.h.

#define ISC_RDEV_CFG_EX	(		csi,
			i2c,
			disPwrCtrl
	)

Value:

((i2c & 0xffu) | \
          ((uint32_t)(csi & 0xffu) << RDEV_CFG_I2C_BITS) | \
          ((uint32_t)(disPwrCtrl & 1u) << RDEV_CFG_SLV_BIT))

Extended macro to create root device configuration to generate the configuration of the root device by its connected CSI port and I2C bus with an option to disable power control from root device.

Parameters

[in]	csi	The CSI port number defined in NvMediaICPInterfaceType.
[in]	i2c	The I2C bus number defined in NvMediaISC_I2CPort.
[in]	disPwrCtrl	The flag to disable power control, possible values are 0 or 1. If the value is 0, root device will turn on the power of devices in NvMediaISCRootDeviceCreate. If the value is 1, root device won't turn on the power of devices in NvMediaISCRootDeviceCreate.

Definition at line 84 of file nvmedia_isc.h.

#define ISC_SLV_RDEV_CFG	(		csi,
			i2c
	)		((i2c) | ((uint32_t)(csi) << RDEV_CFG_I2C_BITS) | ((uint32_t)(1u) << RDEV_CFG_CSI_BITS))

Macro to create a slave root device configuration when the application is being run on slave tegra.

to generate the configuration of the root device by its connected CSI port and I2C bus.

Parameters

[in]	csi	The CSI port number defined in NvMediaICPInterfaceType.
[in]	i2c	The I2C bus number defined in NvMediaISC_I2CPort.
