Function Documentation

static __inline BFU data_unpack ( QDF_tkrCtx *  ctx,
QDF_tkrTwrErrTimeout *  twr,
const unsigned int *  src,
unsigned int  max,
BFU  bfu 
) [static]

Unpacks the data portion of GTRC commands. This includes

Returns:
The unpacking context
Parameters:
ctx The static tracker unpacking context.
twr The data to be filled in for this erring tower
src The decoding source array.
max The maximum legitimate bit position in src
bfu The decoding context.

static __inline unsigned int header_flip_gtccs ( const unsigned char *  map,
unsigned int  gtccs 
) [static]

Flips the even and odd bits of a gtcc bit mask (right justified).

Returns:
The flipped bit mask
Parameters:
map The map used to flip the header. This is strictly a bow to efficiency. By providing this as an argument instead of an internal static, it prevents the reestablishment of the address on each call. (Likely only effective on a machine with lots of registers.)
gtccs The 8-bit value to bit-reverse.

static __inline BFU header_unpack_nto_rcs ( QDF_tkrCtx *  ctx,
QDF_tkrTwrErrTimeout *  twr,
const unsigned int *  src,
const unsigned int  max,
BFU  bfu 
) [static]

Fills in the status of the RCs on non timed out RCs.

Returns:
The unpacking context
Parameters:
ctx The static tracker unpacking context.
twr The data to be filled in for this erring tower
src The decoding source array.
max The maximum legitimate bit position in src
bfu The decoding context.

static __inline BFU header_unpack_to_rcs ( QDF_tkrCtx *  ctx,
QDF_tkrTwrErrTimeout *  twr,
unsigned int  xlist,
unsigned int  ccs,
int  nccs,
const unsigned int *  src,
const unsigned int  max,
BFU  bfu 
) [static]

Fills in the status of the RCs on timed out CCs.

Returns:
The unpacking context
Parameters:
ctx The static tracker unpacking context.
twr The data to be filled in for this erring tower
xlist A bit mask indicating which exception conditions are present. This is a left justified mask.
  • Bit 0: RC0s with only timeouts
  • Bit 1: RC0s with DAV
  • Bit 2: RC0S with TAG_ERR
  • Bit 3: RC0S with ERROR
ccs A bit mask giving which CCs have timed-out. This is a left justified mask.
nccs The count of CCs that have timed-out i.e. the number of bits that are set in ccs.
src The decoding source array.
max The maximum legitimate bit position in src
bfu The decoding context.

static __inline BFU lzs_fill_cnts ( unsigned short int *  cnts[8],

Returns:
The unpacking context
Parameters:
cnts Pointer to the array of 8 RC leading counts to fill
bfu The bit stream decoding context
max The maximum bit offset allowed
src The underlying input buffer.

) [static]

Unpacks the leading zero count from the bit stream.

Returns:
The unpacking context
Parameters:
