The second phase of syscons reorganization. - 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 <naddy@mips.rhein-neckar.de> - 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.

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.

Changed the first (name) arg of MOD_DEV(), MOD_EXEC() and MOD_MISC() from a string to an identifier so that it can be used to generate declarations and strings. It's much easier to stringize an identifier than to identifize a string. A uniform naming scheme must be used for the automatically generated things to apply. This is a feature. Used the module identifer to generate prototypes for the module load, unload and stat functions. Removed the few prototypes for these that already existed. Used the module identifier to generate a unique struct tag in MOD_DEV(). This should probably be done for all the MOD_*() macros. Moved the trailing semicolon from the MOD_*() macro definitions to the macro invocations that didn't already (bogusly) have it. Staticized the module load and unload functions. Added function return types for the module load, unload and stat functions. lkm/ibcs2/ibcs2.c: Included <sys/sysproto.h> to get everything prototyped. Cleaned up #includes. lkm/ibcs2/ipfw.c: Cleaned up #includes. lkm/linux/linux.c: The module name had to change from "linux_emulator" to "linux_mod" to be automatically generated. Cleaned up #includes. lkm/syscons/*/*_saver.c: Completed delcarations of function pointers. sys/i386/isa/atapi.c: The module name had to change from "atapi" to "atapi_mod" to be automatically generated. sys/i386/isa/wcd.c: Used the fixed MOD_DEV(). This module has two devices and expanded the macro in the source instead of fixing it. The module names had to change from "wcd" and "rwcd" to "wcd_mod" and "rwcd_mod" to be automatically generated. sys/pccard/pcic.c: The module name had to change from "pcic" to "pcic_mod" to be automatically generated.
