 216 /*
 217  * The following is some guesswork on how the TV encoder flicker
 218  * filter/rescaler works:
 219  *
 220  * It seems to use some sort of resampling filter, it is controlled
 221  * through the registers at NV_PTV_HFILTER and NV_PTV_VFILTER, they
 222  * control the horizontal and vertical stage respectively, there is
 223  * also NV_PTV_HFILTER2 the blob fills identically to NV_PTV_HFILTER,
 224  * but they seem to do nothing. A rough guess might be that they could
 225  * be used to independently control the filtering of each interlaced
 226  * field, but I don't know how they are enabled. The whole filtering
 227  * process seems to be disabled with bits 26:27 of PTV_200, but we
 228  * aren't doing that.
 229  *
 230  * The layout of both register sets is the same:
 231  *
 232  * A: [BASE+0x18]...[BASE+0x0] [BASE+0x58]..[BASE+0x40]
 233  * B: [BASE+0x34]...[BASE+0x1c] [BASE+0x74]..[BASE+0x5c]
 234  *
 235  * Each coefficient is stored in bits [31],[15:9] in two's complement
 236  * format. They seem to be some kind of weights used in a low-pass
 237  * filter. Both A and B coefficients are applied to the 14 nearest
 238  * samples on each side (Listed from nearest to furthermost.  They
 239  * roughly cover 2 framebuffer pixels on each side).  They are
 240  * probably multiplied with some more hardwired weights before being
 241  * used: B-coefficients are applied the same on both sides,
 242  * A-coefficients are inverted before being applied to the opposite
 243  * side.
 244  *
 245  * After all the hassle, I got the following formula by empirical
 246  * means...
