1 ============================================ 2 Framebuffer driver for Cirrus Logic chipsets 3 ============================================ 4 5 Copyright 1999 Jeff Garzik <jgarzik@pobox.com> 6 7 8 .. just a little something to get people going; contributors welcome! 9 10 11 Chip families supported: 12 - SD64 13 - Piccolo 14 - Picasso 15 - Spectrum 16 - Alpine (GD-543x/4x) 17 - Picasso4 (GD-5446) 18 - GD-5480 19 - Laguna (GD-546x) 20 21 Bus's supported: 22 - PCI 23 - Zorro 24 25 Architectures supported: 26 - i386 27 - Alpha 28 - PPC (Motorola Powerstack) 29 - m68k (Amiga) 30 31 32 33 Default video modes 34 ------------------- 35 At the moment, there are two kernel command line arguments supported: 36 37 - mode:640x480 38 - mode:800x600 39 - mode:1024x768 40 41 Full support for startup video modes (modedb) will be integrated soon. 42 43 Version 1.9.9.1 44 --------------- 45 * Fix memory detection for 512kB case 46 * 800x600 mode 47 * Fixed timings 48 * Hint for AXP: Use -accel false -vyres -1 when changing resolution 49 50 51 Version 1.9.4.4 52 --------------- 53 * Preliminary Laguna support 54 * Overhaul color register routines. 55 * Associated with the above, console colors are now obtained from a LUT 56 called 'palette' instead of from the VGA registers. This code was 57 modelled after that in atyfb and matroxfb. 58 * Code cleanup, add comments. 59 * Overhaul SR07 handling. 60 * Bug fixes. 61 62 63 Version 1.9.4.3 64 --------------- 65 * Correctly set default startup video mode. 66 * Do not override ram size setting. Define 67 CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM 68 setting. 69 * Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes. 70 * Use new 2.3.x resource allocation. 71 * Some code cleanup. 72 73 74 Version 1.9.4.2 75 --------------- 76 * Casting fixes. 77 * Assertions no longer cause an oops on purpose. 78 * Bug fixes. 79 80 81 Version 1.9.4.1 82 --------------- 83 * Add compatibility support. Now requires a 2.1.x, 2.2.x or 2.3.x kernel. 84 85 86 Version 1.9.4 87 ------------- 88 * Several enhancements, smaller memory footprint, a few bugfixes. 89 * Requires kernel 2.3.14-pre1 or later. 90 91 92 Version 1.9.3 93 ------------- 94 * Bundled with kernel 2.3.14-pre1 or later.
