+
+ A context object is referenced by a user defined handle (CARD32). The HW

+
+ 15: 0 instance_addr >> 4 (maybe 19-0)
+ 21:20 engine (here uses 1 = graphics)
+ I'm unsure about the other bits, but using 0 seems to work.

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