-   Amiga video timings
-   -------------------
-
-   The Amiga native chipsets uses another timing scheme:
-
-      - hsstrt:   Start of horizontal synchronization pulse
-      - hsstop:   End of horizontal synchronization pulse
-      - htotal:   Last value on the line (i.e. line length = htotal+1)
-      - vsstrt:   Start of vertical synchronization pulse
-      - vsstop:   End of vertical synchronization pulse
-      - vtotal:   Last line value (i.e. number of lines = vtotal+1)
-      - hcenter:  Start of vertical retrace for interlace
-
-   You can specify the blanking timings independently. Currently I just set
-   them equal to the respective synchronization values:
-
-      - hbstrt:   Start of horizontal blank
-      - hbstop:   End of horizontal blank
-      - vbstrt:   Start of vertical blank
-      - vbstop:   End of vertical blank
-
-   Horizontal values are in color clock cycles (280 ns), vertical values are in
-   scanlines.
-
-   (0, 0) is somewhere in the upper-left corner :-)
-
-
-   Amiga visible window definitions
-   --------------------------------
-
-   Currently I only have values for AGA, SHRES (28 MHz dotclock). Feel free to
-   make corrections and/or additions.
-
-   Within the above synchronization specifications, the visible window is
-   defined by the following parameters (actual register resolutions may be
-   different; all horizontal values are normalized with respect to the pixel
-   clock):
-
-      - diwstrt_h:   Horizontal start of the visible window
-      - diwstop_h:   Horizontal stop+1(*) of the visible window
-      - diwstrt_v:   Vertical start of the visible window
-      - diwstop_v:   Vertical stop of the visible window
-      - ddfstrt:     Horizontal start of display DMA
-      - ddfstop:     Horizontal stop of display DMA
-      - hscroll:     Horizontal display output delay
-
-   Sprite positioning:
-
-      - sprstrt_h:   Horizontal start-4 of sprite
-      - sprstrt_v:   Vertical start of sprite
-
-   (*) Even Commodore did it wrong in the AGA monitor drivers by not adding 1.
-
-   Horizontal values are in dotclock cycles (35 ns), vertical values are in
-   scanlines.
-
-   (0, 0) is somewhere in the upper-left corner :-)
-
-
-   Dependencies (AGA, SHRES (35 ns dotclock))
-   -------------------------------------------
-
-   Since there are much more parameters for the Amiga display than for the
-   frame buffer interface, there must be some dependencies among the Amiga
-   display parameters. Here's what I found out:
-
-      - ddfstrt and ddfstop are best aligned to 64 pixels.
-      - the chipset needs 64+4 horizontal pixels after the DMA start before the
-        first pixel is output, so diwstrt_h = ddfstrt+64+4 if you want to
-        display the first pixel on the line too. Increase diwstrt_h for virtual
-        screen panning.
-      - the display DMA always fetches 64 pixels at a time (fmode = 3).
-      - ddfstop is ddfstrt+#pixels-64.
-      - diwstop_h = diwstrt_h+xres+1. Because of the additional 1 this can be 1
-        more than htotal.
-      - hscroll simply adds a delay to the display output. Smooth horizontal
-        panning needs an extra 64 pixels on the left to prefetch the pixels that
-        `fall off' on the left.
-      - if ddfstrt < 192, the sprite DMA cycles are all stolen by the bitplane
-        DMA, so it's best to make the DMA start as late as possible.
-      - you really don't want to make ddfstrt < 128, since this will steal DMA
-        cycles from the other DMA channels (audio, floppy and Chip RAM refresh).
-      - I make diwstop_h and diwstop_v as large as possible.
-
-   General dependencies
-   --------------------
-
-      - all values are SHRES pixel (35ns)
-
-                  table 1:fetchstart  table 2:prefetch    table 3:fetchsize
-                  ------------------  ----------------    -----------------
-   Pixclock     # SHRES|HIRES|LORES # SHRES|HIRES|LORES # SHRES|HIRES|LORES
-   -------------#------+-----+------#------+-----+------#------+-----+------
-   Bus width 1x #   16 |  32 |  64  #   16 |  32 |  64  #   64 |  64 |  64
-   Bus width 2x #   32 |  64 | 128  #   32 |  64 |  64  #   64 |  64 | 128
-   Bus width 4x #   64 | 128 | 256  #   64 |  64 |  64  #   64 | 128 | 256
-
-      - chipset needs 4 pixels before the first pixel is output
-      - ddfstrt must be aligned to fetchstart (table 1)
-      - chipset needs also prefetch (table 2) to get first pixel data, so
-        ddfstrt = ((diwstrt_h-4) & -fetchstart) - prefetch
-      - for horizontal panning decrease diwstrt_h
-      - the length of a fetchline must be aligned to fetchsize (table 3)
-      - if fetchstart is smaller than fetchsize, then ddfstrt can a little bit
-        moved to optimize use of dma (usefull for OCS/ECS overscan displays)
-      - ddfstop is ddfstrt+ddfsize-fetchsize
-      - If C= didn't change anything for AGA, then at following positions the
-        dma bus is allready used:
-        ddfstrt <  48 -> memory refresh
-                <  96 -> disk dma
-                < 160 -> audio dma
-                < 192 -> sprite 0 dma
-                < 416 -> sprite dma (32 per sprite)
-      - in accordance with the hardware reference manual a hardware stop is at
-        192, but AGA (ECS?) can go below this.
-
-   DMA priorities
-   --------------
-
-   Since there are limits on the earliest start value for display DMA and the
-   display of sprites, I use the following policy on horizontal panning and
-   the hardware cursor:
-
-      - if you want to start display DMA too early, you loose the ability to
-        do smooth horizontal panning (xpanstep 1 -> 64).
-      - if you want to go even further, you loose the hardware cursor too.
-
-   IMHO a hardware cursor is more important for X than horizontal scrolling,
-   so that's my motivation.
-
-
-   Implementation
-   --------------
-
-   ami_decode_var() converts the frame buffer values to the Amiga values. It's
-   just a `straightforward' implementation of the above rules.
-
-
-   Standard VGA timings
-   --------------------
-
-               xres  yres    left  right  upper  lower    hsync    vsync
-               ----  ----    ----  -----  -----  -----    -----    -----
-      80x25     720   400      27     45     35     12      108        2
-      80x30     720   480      27     45     30      9      108        2
-
-   These were taken from a XFree86 configuration file, recalculated for a 28 MHz
-   dotclock (Amigas don't have a 25 MHz dotclock) and converted to frame buffer
-   generic timings.
-
-   As a comparison, graphics/monitor.h suggests the following:
-
-               xres  yres    left  right  upper  lower    hsync    vsync
-               ----  ----    ----  -----  -----  -----    -----    -----

-
-   Broadcast video timings
-   -----------------------
-
-   According to the CCIR and RETMA specifications, we have the following values:
-
-   CCIR -> PAL
-   -----------
-
-      - a scanline is 64 µs long, of which 52.48 µs are visible. This is about
-        736 visible 70 ns pixels per line.
-      - we have 625 scanlines, of which 575 are visible (interlaced); after
-        rounding this becomes 576.
-
-   RETMA -> NTSC
-   -------------
-
-      - a scanline is 63.5 µs long, of which 53.5 µs are visible.  This is about
-        736 visible 70 ns pixels per line.
-      - we have 525 scanlines, of which 485 are visible (interlaced); after
-        rounding this becomes 484.
-
-   Thus if you want a PAL compatible display, you have to do the following:
-
-      - set the FB_SYNC_BROADCAST flag to indicate that standard broadcast
-        timings are to be used.
-      - make sure upper_margin+yres+lower_margin+vsync_len = 625 for an
-        interlaced, 312 for a non-interlaced and 156 for a doublescanned
-        display.
-      - make sure left_margin+xres+right_margin+hsync_len = 1816 for a SHRES,
-        908 for a HIRES and 454 for a LORES display.
-      - the left visible part begins at 360 (SHRES; HIRES:180, LORES:90),
-        left_margin+2*hsync_len must be greater or equal.
-      - the upper visible part begins at 48 (interlaced; non-interlaced:24,
-        doublescanned:12), upper_margin+2*vsync_len must be greater or equal.
-      - ami_encode_var() calculates margins with a hsync of 5320 ns and a vsync
-        of 4 scanlines
-
-   The settings for a NTSC compatible display are straightforward.
-
-   Note that in a strict sense the PAL and NTSC standards only define the
-   encoding of the color part (chrominance) of the video signal and don't say
-   anything about horizontal/vertical synchronization nor refresh rates.

- * A small info on how to convert XFree86 timing values into fb
- * timings - by Frank Neumann:
- *
-An XFree86 mode line consists of the following fields:
- "800x600"     50      800  856  976 1040    600  637  643  666
- < name >     DCF       HR  SH1  SH2  HFL     VR  SV1  SV2  VFL
-
-The fields in the fb_var_screeninfo structure are:
-        unsigned long pixclock;         * pixel clock in ps (pico seconds) *
-        unsigned long left_margin;      * time from sync to picture    *
-        unsigned long right_margin;     * time from picture to sync    *
-        unsigned long upper_margin;     * time from sync to picture    *
-        unsigned long lower_margin;
-        unsigned long hsync_len;        * length of horizontal sync    *
-        unsigned long vsync_len;        * length of vertical sync      *
-
-1) Pixelclock:
-   xfree: in MHz
-   fb: In Picoseconds (ps)
-
-   pixclock = 1000000 / DCF
-
-2) horizontal timings:
-   left_margin = HFL - SH2
-   right_margin = SH1 - HR
-   hsync_len = SH2 - SH1
-
-3) vertical timings:
-   upper_margin = VFL - SV2
-   lower_margin = SV1 - VR
-   vsync_len = SV2 - SV1
-
-Good examples for VESA timings can be found in the XFree86 source tree,
-under "programs/Xserver/hw/xfree86/doc/modeDB.txt".
