- Prototype
-
int intel_vvp_vc_set_v_ramp_m1_frac(intel_vvp_vc_instance* instance, uint32_t v_ramp_m1_frac);
- Description
-
Writes the fraction of corrective gain for each vertical pixel step within the last mesh box. The instance must be a valid intel_vvp_vc_instance fully initialized.
- Arguments
-
instance - pointer to the intel_vvp_vc_instance software driver instance structure
v_ramp_m1_frac - new fraction of corrective gain for each vertical pixel step within the last mesh box
- Returns
-
kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error
kIntelVvpCoreInstanceErr if the instance is a null pointer
kIntelVvpVcValueErr if the value of v_ramp_m1_frac is out of range

- Returns
-
kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error
kIntelVvpCoreInstanceErr if the instance is a null pointer
kIntelVvpVcPointerErr if cp_lut_values is a null pointer
kIntelVvpVcParameterErr if cp_lut_idx is out of range
kIntelVvpVcLutNotAvailableErr if the lookup table is not available for this instance

- Prototype
-
int intel_vvp_vc_update_step_lut(intel_vvp_vc_instance* instance, const uint32_t* step_lut_values);
- Description
-
Writes the step lookup table from a vector. The instance must be a valid intel_vvp_vc_instance fully initialized.
- Arguments
-
instance - pointer to the intel_vvp_vc_instance software driver instance structure
step_lut_values - pointer of a vector of lookup table values
- Returns
-
kIntelVvpCoreOk (0) in case of success, a negative error code in case of an error
kIntelVvpCoreInstanceErr if the instance is a null pointer
kIntelVvpVcPointerErr if step_lut_values is a null pointer
kIntelVvpVcLutInvalidNumBlocksErr if the number of horizontal or vertical blocks were misconfigured to zero in a previous function call
