|
From: <Jos...@vi...> - 2008-08-12 00:57:53
|
Correct the description of VX800 2D acceleration, the driver diables the acceleration function by defualt if you use VX800 chip. Correct via_fb_ to viafb_ and remove the Kconfig part in viafb.txt. viafb.modes: supported mode table viafb.txt: documentation of viafb driver Signed-off-by: Joseph Chan <jos...@vi...> diff -Nurp

It is different from + multi-head since SAMM support multi monitor at driver layers, thus fbcon + layer doesn't even know about it; SAMM's second screen doesn't have a + device node file, thus a user mode application can't access it directly. + When SAMM is enabled, viafb_mode and viafb_mode1, viafb_bpp and + viafb_bpp1, viafb_refresh and viafb_refresh1 can be different. + 3. When console is depending on viafbinfo1, dynamically change resolution + and bpp, need to call VIAFB specified ioctl interface VIAFB_SET_DEVICE + instead of calling common ioctl function FBIOPUT_VSCREENINFO since + viafb doesn't support multi-head well, or it will cause screen crush. + 4.
