From f7018c21350204c4cf628462f229d44d03545254 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 13 Feb 2014 15:31:38 +0200 Subject: video: move fbdev to drivers/video/fbdev The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.

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 (useful 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 already 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 lose the ability to - do smooth horizontal panning (xpanstep 1 -> 64). - - if you want to go even further, you lose 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 - ---- ---- ---- ----- ----- ----- ----- ----- - - VGA 640 480 52 112 24 19 112 - 2 + - VGA70 640 400 52 112 27 21 112 - 2 - - - - Sync polarities - --------------- - - VSYNC HSYNC Vertical size Vertical total - ----- ----- ------------- -------------- - + + Reserved Reserved - + - 400 414 - - + 350 362 - - - 480 496 - - Source: CL-GD542X Technical Reference Manual, Cirrus Logic, Oct 1992 - - - 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. - - - -- Geert -- - -*******************************************************************************/ -

The interface between the board and the host is TTL based GPIO. The - * GPIO requirements are 8 writable data lines and 4+n lines for control. On a - * GPIO-less system, the board can be tested by connecting the respective sigs - * up to a parallel port connector. The driver requires the IO addresses for - * data and control GPIO at load time. It is unable to probe for the - * existence of the LCD so it must be told at load time whether it should - * be enabled or not. - * - * Todo: - * - testing with 4x4 - * - testing with interrupt hw - * - * General notes: - * - User must set tuhold.
