AFAIK, these assumptions are all part of the VGA standard - if you have a VGA-compatible graphics card then it will provide standard font and text modes as used by syscons and pcvt. And the only non-VGA graphics adapter I'm aware of is the DEC TGA (though it seems likely that some or all of the Sun framebuffers don't support VGA. I don't see any reason to not use the VGA features if they're available and unless there's a lot of non-VGA adapters around, they can be treated on a case-by-case basis. >As far as I could see this has be more or less resolved with the tga adapter >driver for alpha arch for which a renderer has been introduced to tackle down >framebuffer only video adapters. It's not clear how much of the TGA renderer could be reused by another FB-only adapter. Whilst the renderer is mostly rendering into a raw framebuffer, there are a fair number of implicit assumptions about how the bits in the framebuffer RAM turn into pixels on the screen. Note that this driver explicitly uses VGA mode if it detects a TGA2 adapter. Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
