This code was 58 modeled after that in atyfb and matroxfb. 59* Code cleanup, add comments. 60* Overhaul SR07 handling. 61* Bug fixes. 62 63 64Version 1.9.4.3 65--------------- 66* Correctly set default startup video mode. 67* Do not override ram size setting. Define 68 CLGEN_USE_HARDCODED_RAM_SETTINGS if you _do_ want to override the RAM 69 setting. 70* Compile fixes related to new 2.3.x IORESOURCE_IO[PORT] symbol changes. 71* Use new 2.3.x resource allocation. 72* Some code cleanup. 73 74 75Version 1.9.4.2 76--------------- 77* Casting fixes. 78* Assertions no longer cause an oops on purpose. 79* Bug fixes. 80 81 82Version 1.9.4.1 83--------------- 84* Add compatibility support. Now requires a 2.1.x, 2.2.x or 2.3.x kernel. 85 86 87Version 1.9.4 88------------- 89* Several enhancements, smaller memory footprint, a few bugfixes. 90* Requires kernel 2.3.14-pre1 or later. 91 92 93Version 1.9.3 94------------- 95* Bundled with kernel 2.3.14-pre1 or later. 96 97 98
