TGA -cards, which are usually found in older Digital Alpha systems. The -following models are supported: - -ZLxP-E1 (8bpp, 2 MB VRAM) -ZLxP-E2 (32bpp, 8 MB VRAM) -ZLxP-E3 (32bpp, 16 MB VRAM, Zbuffer) - -This version is an almost complete rewrite of the code written by Geert -Uytterhoeven, which was based on the original TGA console code written by -Jay Estabrook. - -Major new features since Linux 2.0.x: - - * Support for multiple resolutions - * Support for fixed-frequency and other oddball monitors - (by allowing the video mode to be set at boot time) - -User-visible changes since Linux 2.2.x: - - * Sync-on-green is now handled properly - * More useful information is printed on bootup - (this helps if people run into problems) - -This driver does not (yet) support the TGA2 family of framebuffers, so the -PowerStorm 3D30/4D20 (also known as PBXGB) cards are not supported. These -can however be used with the standard VGA Text Console driver. - - -Configuration -============= - -You can pass kernel command line options to tgafb with -`video=tgafb:option1,option2:value2,option3' (multiple options should be -separated by comma, values are separated from options by `:'). -Accepted options: - -font:X - default font to use. All fonts are supported, including the - SUN12x22 font which is very nice at high resolutions. - -mode:X - default video mode. The following video modes are supported: - 640x480-60, 800x600-56, 640x480-72, 800x600-60, 800x600-72, - 1024x768-60, 1152x864-60, 1024x768-70, 1024x768-76, - 1152x864-70, 1280x1024-61, 1024x768-85, 1280x1024-70, - 1152x864-84, 1280x1024-76, 1280x1024-85 - - -Known Issues -============ - -The XFree86 FBDev server has been reported not to work, since tgafb doesn't do -mmap(). Running the standard XF86_TGA server from XFree86 3.3.x works fine for -me, however this server does not do acceleration, which make certain operations -quite slow. Support for acceleration is being progressively integrated in -XFree86 4.x. - -When running tgafb in resolutions higher than 640x480, on switching VCs from -tgafb to XF86_TGA 3.3.x, the entire screen is not re-drawn and must be manually -refreshed. This is an X server problem, not a tgafb problem, and is fixed in -XFree86 4.0. - -Enjoy! - -Martin Lucina <mato@kotelna.sk> |
