15 | * 0.4.1 | |
16 | * - Cosmetic changes (dok) | |
17 | * | |
18 | * 0.4 | |
19 | * - Toshiba Libretto support, allow modes larger than LCD size if | |
20 | * LCD is disabled, keep BIOS settings if internal/external display | |
21 | * haven't been enabled explicitly | |
22 | * (Thomas J. Moore <dark@mama.indstate.edu>) | |
23 | * | |
24 | * 0.3.3 | |
25 | * - Porting over to new fbdev api. (jsimmons) | |
26 | * | |
27 | * 0.3.2 | |
28 | * - got rid of all floating point (dok) | |
29 | * | |
30 | * 0.3.1 | |
31 | * - added module license (dok) | |
32 | * | |
33 | * 0.3 | |
34 | * - hardware accelerated clear and move for 2200 and above (dok) | |
35 | * - maximum allowed dotclock is handled now (dok) | |
36 | * | |
37 | * 0.2.1 | |
38 | * - correct panning after X usage (dok) | |
39 | * - added module and kernel parameters (dok) | |
40 | * - no stretching if external display is enabled (dok) | |
41 | * | |
42 | * 0.2 | |
43 | * - initial version (dok) | |
44 | * | |
45 | * | |
46 | * TODO | |
47 | * - ioctl for internal/external switching | |
48 | * - blanking | |
49 | * - 32bit depth support, maybe impossible | |
50 | * - disable pan-on-sync, need specs | |
51 | * | |
52 | * BUGS | |
53 | * - white margin on bootup like with tdfxfb (colormap problem?) | |
