The second phase of syscons reorganization.

1999-06-22T14:14:06Z

- Split syscons source code into manageable chunks and reorganize some of complicated functions. - Many static variables are moved to the softc structure. - Added a new key function, PREV. When this key is pressed, the vty immediately before the current vty will become foreground. Analogue to PREV, which is usually assigned to the PrntScrn key. PR: kern/10113 Submitted by: Christian Weisgerber - Modified the kernel console input function sccngetc() so that it handles function keys properly. - Reorganized the screen update routine. - VT switching code is reorganized. It now should be slightly more robust than before. - Added the DEVICE_RESUME function so that syscons no longer hooks the APM resume event directly. - New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING, SC_NO_HISTORY and SC_NO_SYSMOUSE. Various parts of syscons can be omitted so that the kernel size is reduced. SC_PIXEL_MODE Made the VESA 800x600 mode an option, rather than a standard part of syscons. SC_DISABLE_DDBKEY Disables the `debug' key combination. SC_ALT_MOUSE_IMAGE Inverse the character cell at the mouse cursor position in the text console, rather than drawing an arrow on the screen. Submitted by: Nick Hibma (n_hibma@FreeBSD.ORG) SC_DFLT_FONT makeoptions "SC_DFLT_FONT=_font_name_" Include the named font as the default font of syscons. 16-line, 14-line and 8-line font data will be compiled in. This option replaces the existing STD8X16FONT option, which loads 16-line font data only. - The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c. - The video driver provides a set of ioctl commands to manipulate the frame buffer. - New kernel configuration option: VGA_WIDTH90 Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These modes are mot always supported by the video card. PR: i386/7510 Submitted by: kbyanc@freedomnet.com and alexv@sui.gda.itesm.mx. - The header file machine/console.h is reorganized; its contents is now split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h (another new file). machine/console.h is still maintained for compatibility reasons. - Kernel console selection/installation routines are fixed and slightly rebumped so that it should now be possible to switch between the interanl kernel console (sc or vt) and a remote kernel console (sio) again, as it was in 2.x, 3.0 and 3.1. - Screen savers and splash screen decoders Because of the header file reorganization described above, screen savers and splash screen decoders are slightly modified. After this update, /sys/modules/syscons/saver.h is no longer necessary and is removed.

The first stage of console driver reorganization: activate new

keyboard and video card drivers. Because of the changes, you are required to update your kernel configuration file now! The files in sys/dev/syscons are still i386-specific (but less so than before), and won't compile for alpha and PC98 yet. syscons still directly accesses the video card registers here and there; this will be rectified in the later stages.

Simple update to make these work as kld and preload modules.

Fix the sreensavers so the work again with the new syscons & friends.

Add VESA support to syscons.

1998-09-15T18:16:39Z

Kazu writes: The VESA support code requires vm86 support. Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i ' option, where must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

Make the blank screen saver work with MDA and CGA. The fade and green

1997-10-04T04:24:18Z

savers are also modified so that they behave in the same way as the blank saver on MDA and CGA, although it's not the way these screen savers are supposed to work, but fading monitor and tickling green monitor cannot be done on MDA and CGA, AFAIK. So, this is the second best solution. As of this change, the current state of support of screen savers is summarized in the following table. MDA CGA EGA VGA blank OK OK NA OK daemon OK OK OK OK fade * * NA OK green * * NA OK snake OK OK OK OK star OK OK OK OK OK: works NA: doesn't work, the module cannot be loaded for this adapter. *: behave the same way as the blank saver. As you can see, EGA is left out for now. But, we can do no better, as EGA registers cannot be read... Reviewed by: sos

Incorporated lots of fixes and suggestions from Bruce and changes to

facilitate the new saver loading/unloading notification interface in syscons. daemon_saver: - M_NOWAIT was wrong, since NULL returns are not handled. Just use M_WAITOK. - use `ostype' instead of hard-coded "FreeBSD". Now there is no more hard-coded string! (But, who will run this screen saver on other OS?!) - put macros and data declarations in a consistent order. - -DDEAMON_ONLY and -DSHOW_HOSTNAME options added in the previous commit are removed. Options of this kind can go stale and no one notices because no one uses them. DEAMON_ONLY is just removed. SHOW_HOSTNAME is made default. snake_saver: - use `ostype' and `osrelease' as in the daemon saver. The string changes slightly - there was a hyphen after "FreeBSD"; now there is a space. (It is consistent with uname -a, like the daemon server already is.) all screen savers: - Use the new add_scrn_saver()/remove_scrn_saver() in syscons.c to declare loading/unloading of a screen saver. Removed reference to `current_saver' and the variable `old_saver' as they are not necessary anymore. - The blank, fade and green screen savers manipulate VGA registers. Module loading should fail for non-VGA cards. - `scrn_blanked' is consistently treated as a number/counter rather than boolean. - Some savers touch `scp->start' and `scp->end' to force entire screen update when stopping themselves. This is unnecessary now because syscons.c takes care of that. - cleared up many unused or unnecessary #include statements. - Removed -DLKM from Makefiles. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THIS CHANGE.

Make MOD_* macros almost consistent:

1997-04-06T10:49:22Z

Use the name argument almost the same in all LKM types. Maintain the current behavior for the external (e.g., modstat) name for DEV, EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only #name. This is a candidate for change and I vote just the name without the "_mod". Change the DISPATCH macro to MOD_DISPATCH for consistency with the other macros. Add an LKM_ANON #define to eliminate the magic -1 and associated signed/unsigned warnings. Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure. Change source in tree to use the new interface. Reviewed by: Bruce Evans
