[Nouveau] [PATCHv2 01/10] drm/nouveau: Fix a lock up at NVSetOwner with nv11.
It seems it was only locking up in the context of
nouveau_hw_save_vga_fonts, when it actually did something (because
the console wasn't already in graphics mode).

[Nouveau] [PATCHv2 02/10] drm/nouveau: Fix fbcon with multiple outputs connected.
vgacon attempts to restore the CRTC base on deinit so it messes up the
second head scanout address. Call crtc->helper_funcs->mode_set_base
directly from nouveau_fbcon_pan_display to ensure it's written out
even if the coordinates haven't changed. Modify nouveau_fbcon_set_par
so that it always calls crtc->funcs->set_config.

[Nouveau] [PATCHv2 05/10] drm/nouveau: Restructure the nv04 modesetting code.
* Delay the hardware state synchronization to crtc->commit(). This way
the encoder-specific code can adjust the CRTC regs on mode_set()
before they're written out.
* Don't abuse adjusted_mode to mean the output side mode, this makes
impossible for the encoder code to fix up the actual CRTC mode.
* Split the digital from the analog stuff, as they have almost no
common code and IMHO this will substantially improve consistency
once the TVDAC implementation is imported.

+ * 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...
