GLBCE Configuration

Introduction

This is VISS GLBCE Configuration file

Files
file	glbce_cfg.h
	Interface file for GLBCE module, Defines the structures / control operations that could be used to configure / control GLBCE module in VISS GLBCE is independent module, between RAW FE and FCFA. This is why a separate interface file is used for controlling GLBCE.

Data Structures
struct	Glbce_Config
	GLBCE configuration structure Used to configure common GLBCE configuration which is used for contrast brightness enhancement. More...
struct	Glbce_PerceptConfig

struct	Glbce_WdrConfig
	Control structure for WDR Module. Used to enable/disable module and to set WDR Lut. More...
struct	Glbce_StatsInfo
	GLBCE Stats memory information Used to get the address and size of the GLBCE statistics memory for the context save and restore purpose. More...
struct	Glbce_Control
	GLBCE control structure, passed as an argument to IOCTL_GLBCE_SET_CONFIG. More...

Macros
#define	GLBCE_ASYMMETRY_LUT_SIZE   (33U)

GLBCE IOCTL macros
Control Commands for GLBCE module in VISS
#define	IOCTL_GLBCE_SET_CONFIG
	Used for setting individual GLBCE sub-module's configuration. Single ioctl for configuring all sub-module's configuration, by selecting module id and setting appropriate pointer in Glbce_Control. More...
#define	IOCTL_GLBCE_GET_CONFIG
	Used for getting individual GLBCE sub-module's configuration. Single ioctl for configuring all sub-module's configuration, by selecting module id and setting appropriate pointer in Glbce_Control. More...

GLBCE Dithering Size
Defines number of bits to dither at the GLBCE output. Caution: The values of this macro is directly in configuring register

Macro Definition Documentation

IOCTL_GLBCE_SET_CONFIG

#define IOCTL_GLBCE_SET_CONFIG

Value:

(VHWA_IOCTL_GLBCE_IOCTL_BASE + \
    1U)

Used for setting individual GLBCE sub-module's configuration. Single ioctl for configuring all sub-module's configuration, by selecting module id and setting appropriate pointer in Glbce_Control.

Returns

FVID2_SOK on success, else error code.

IOCTL_GLBCE_GET_CONFIG

#define IOCTL_GLBCE_GET_CONFIG

Value:

(VHWA_IOCTL_GLBCE_IOCTL_BASE + \
    2U)

Used for getting individual GLBCE sub-module's configuration. Single ioctl for configuring all sub-module's configuration, by selecting module id and setting appropriate pointer in Glbce_Control.

Currently this is supported only Statistics information.

Returns

FVID2_SOK on success, else error code.
