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