Functions

static BFU cal_ped1_style_0 (QDF_calCtx *ctx, QDF_calEvt *evt, const unsigned int *src, const unsigned int max, BFU bfu)
 Decodes the CAL when encoded as in style 0 format. This is format is almost a straight copy of the CAL data.
static BFU cal_ped1_style_1 (QDF_calCtx *ctx, QDF_calEvt *evt, const unsigned int *src, const unsigned int max, BFU bfu)
 Decodes the CAL when encoded using in style 1. This format style uses a limited range huffman table. The limited means that only the central part of the pedestal subtracted data is encoded using a huffman table. Those value outside the central core are encoded in a look-aside exception list.
static BFU cal_ped1_style_2 (QDF_calCtx *ctx, QDF_calEvt *evt, const unsigned int *src, const unsigned int max, BFU bfu)
 Decodes the CAL when encoded using a style 2. Currently there is no style 2, so any CAL data encoded in style 2 represents a serious error.
static BFU cal_ped1_style_3 (QDF_calCtx *ctx, QDF_calEvt *evt, const unsigned int *src, const unsigned int max, BFU bfu)
 Decodes the CAL when encoded using a style 3. Currently there is no style 2, so any CAL data encoded in style 3 represents a serious error.
static BFU cal_ped4_style_0 (QDF_calCtx *ctx, QDF_calEvt *evt, const unsigned int *src, const unsigned int max, BFU bfu)
 Decodes the CAL when encoded as in style 0 format. This is format is almost a straight copy of the CAL data.
static BFU cal_ped4_style_1 (QDF_calCtx *ctx, QDF_calEvt *evt, const unsigned int *src, const unsigned int max, BFU bfu)
