it had claimed while acting as the initial console device. This allows
(for example) vga to be the initial console, and an accelerated
framebuffer driver to take over later.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
to use generic VGA driver(s):
- Allow VGA drivers to use wsfont instead of builtin font.
- Add vga_reset() function, which will be called from MD consinit(),
to put VGA into text mode. This function is enabled by options VGA_RESET.
to char-cell based vga(4) driver, and fully compatible with existing
apps like XFree86. Currently it supports 80x25, 80x30, 80x40 and 80x50
text modes using emulation. You can enable it by specifying `options
VGA_RASTERCONSOLE' in your kernel config file.
Note that displaying multilingual text doesn't work yet. Necessary
code is already there, but userland stuff and some functionality isn't
ready for prime time yet. I'm working on them.
-treat the builtin font like any other font at runtime
-for that, copy it to malloc()'d memory during attach()
-in early console initialization, if we have to consider a broken card
(VGA_CONSOLE_ATI_BROKEN_FONTSEL), copy the builtin font to another
location in font ram; the attach() code will do the rest
put the "quirk" code into effect again
found on many (all?) of PCI-based ATI graphics cards. It is fully optional
and can be enabled by adding `options VGA_CONSOLE_ATI_BROKEN_FONTSEL'
to config file.
- Temporarily remove `quirk' mechanism. Similar code already exists
in pci_quirks.c.
make the number of available font slots variable,
set up a "quirk" mechanism to tell the generic vga code about crippled
VGA adapters which ignore the "fontsel" TS register,
initiate the quirk table with an ATI chip which happened to be on a board
I tested with.
Afaik quite a number of ATI chips suffers from the "loaded fonts don't
work" problem - these should be added.
Bad side effect of my change: The builtin font will be kicked out
always if a VGA_CONSOLE_SCREENTYPE is specified which needs a loaded
font. In early console initialization, we don't know much about the
graphics card, so we have to assume the worst (ie ATI:-).
calls
-support use of 2 fonts simultanously; this costs the ability to
"highlight", ie to use the upper 8 colours
-define screen types "80x25bf" and "80x50bf" which use this ability
-add conditional code to deal with the weird mapping of pcvt's
supplemental fonts
