- * FIXME: We don't check whether the input mode is actually what we want
- * or whether userspace is doing something stupid.
+ * The pipe scanline counter behaviour looks as follows when
+ * using the TV encoder:
+ *
+ * time ->
+ *
+ * dsl=vtotal-1 | |
+ * || ||
+ * ___| | ___| |
+ * / | / |
+ * / | / |
+ * dsl=0 ___/ |_____/ |
+ * | | | | | |
+ * ^ ^ ^ ^ ^
+ * | | | | pipe vblank/first part of tv vblank
+ * | | | bottom margin
+ * | | active
+ * | top margin
+ * remainder of tv vblank
+ *
+ * When the TV encoder is used the pipe wants to run faster
+ * than expected rate. During the active portion the TV
+ * encoder stalls the pipe every few lines to keep it in
+ * check. When the TV encoder reaches the bottom margin the
+ * pipe simply stops. Once we reach the TV vblank the pipe is
+ * no longer stalled and it runs at the max rate (apparently
+ * oversample clock on gen3, cdclk on gen4). Once the pipe
+ * reaches the pipe vtotal the pipe stops for the remainder
+ * of the TV vblank/top margin. The pipe starts up again when
+ * the TV encoder exits the top margin.
+ *
+ * To avoid huge hassles for vblank timestamping we scale
+ * the pipe timings as if the pipe always runs at the average
+ * rate it maintains during the active period. This also
+ * gives us a reasonable guesstimate as to the pixel rate.
+ * Due to the variation in the actual pipe speed the scanline
+ * counter will give us slightly erroneous results during the
+ * TV vblank/margins. But since vtotal was selected such that
+ * it matches the average rate of the pipe during the active
+ * portion the error shouldn't cause any serious grief to
+ * vblank timestamps.
+ *

+ * we can use without causing display corruption. Following
+ * this would allow us to have a ticking scanline counter
+ * everywhere except during the bottom margin (there the
+ * pipe always stops). Ie. this would eliminate the second
+ * flat portion of the above graph. However this would also
+ * complicate vblank timestamping as the pipe vtotal would
+ * no longer match the average rate the pipe runs at during
+ * the active portion. Hence following this formula seems
+ * more trouble that it's worth.
