- arkfb - fbdev driver for ARK Logic chips
- ========================================
-
-
-Supported Hardware
-==================
-
- ARK 2000PV chip
- ICS 5342 ramdac
-
- - only BIOS initialized VGA devices supported
- - probably not working on big endian
-
-
-Supported Features
-==================
-
- * 4 bpp pseudocolor modes (with 18bit palette, two variants)
- * 8 bpp pseudocolor mode (with 18bit palette)
- * 16 bpp truecolor modes (RGB 555 and RGB 565)
- * 24 bpp truecolor mode (RGB 888)
- * 32 bpp truecolor mode (RGB 888)
- * text mode (activated by bpp = 0)
- * doublescan mode variant (not available in text mode)
- * panning in both directions
- * suspend/resume support
-
-Text mode is supported even in higher resolutions, but there is limitation to
-lower pixclocks (i got maximum about 70 MHz, it is dependent on specific
-hardware). This limitation is not enforced by driver. Text mode supports 8bit
-wide fonts only (hardware limitation) and 16bit tall fonts (driver
-limitation). Unfortunately character attributes (like color) in text mode are
-broken for unknown reason, so its usefulness is limited.
-
-There are two 4 bpp modes. First mode (selected if nonstd == 0) is mode with
-packed pixels, high nibble first. Second mode (selected if nonstd == 1) is mode
-with interleaved planes (1 byte interleave), MSB first. Both modes support
-8bit wide fonts only (driver limitation).
-
-Suspend/resume works on systems that initialize video card during resume and
-if device is active (for example used by fbcon).
-
-
-Missing Features
-================
-(alias TODO list)
-
- * secondary (not initialized by BIOS) device support
- * big endian support
- * DPMS support
- * MMIO support
- * interlaced mode variant
- * support for fontwidths != 8 in 4 bpp modes
- * support for fontheight != 16 in text mode
- * hardware cursor
- * vsync synchronization
- * feature connector support
- * acceleration support (8514-like 2D)
-
-
-Known bugs
-==========
-
- * character attributes (and cursor) in text mode are broken
