A rough guess might be that they could 224 * be used to independently control the filtering of each interlaced 225 * field, but I don't know how they are enabled. The whole filtering 226 * process seems to be disabled with bits 26:27 of PTV_200, but we 227 * aren't doing that. 228 * 229 * The layout of both register sets is the same: 230 * 231 * A: [BASE+0x18]...[BASE+0x0] [BASE+0x58]..[BASE+0x40] 232 * B: [BASE+0x34]...[BASE+0x1c] [BASE+0x74]..[BASE+0x5c] 233 * 234 * Each coefficient is stored in bits [31],[15:9] in two's complement 235 * format. They seem to be some kind of weights used in a low-pass 236 * filter. Both A and B coefficients are applied to the 14 nearest 237 * samples on each side (Listed from nearest to furthermost. They 238 * roughly cover 2 framebuffer pixels on each side). They are 239 * probably multiplied with some more hardwired weights before being 240 * used: B-coefficients are applied the same on both sides, 241 * A-coefficients are inverted before being applied to the opposite 242 * side. 243 * 244 * After all the hassle, I got the following formula by empirical 245 * means... 246 */ 247 248 #define calc_overscan(o) interpolate(0x100, 0xe1, 0xc1, o) 249 250 #define id1 (1LL << 8) 251 #define id2 (1LL << 16) 252 #define id3 (1LL << 24) 253 #define id4 (1LL << 32) 254 #define id5 (1LL << 48) 255 256 static struct filter_params{ 257 int64_t k1;
