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...
