* Yet another round of fixes for the VESA support code.Kazutaka YOKOTA1998-10-011-2/+1
| | | | | | | | | | | | | | | | | - Express various sizes in bytes, rather than Kbytes, in the video mode and adapter information structures. - Fill 0 in the linear buffer size field if the linear frame buffer is not available. - Remove SW_VESA_USER ioctl. It is still experimetal and was not meant to be released. - Fix missing cast operator. - Correctly handle pointers returned by the VESA BIOS. The pointers may point to the area either in the BIOS ROM or in the buffer supplied by the caller. - Set the destructive cursor at the right moment. Notes: svn path=/head/; revision=39858

* Fix and update for VESA BIOS support in syscons.Kazutaka YOKOTA1998-09-231-2/+2
| | | | | | | | | | | | | | | | | | | - Handle pixel (raster text) mode properly. - Clear screen and paint border right. - Paint text attribute (colors). - Fix off-by-one errors. - Add some sanity checks. - Fix some function prototypes. - Add some comment lines. - Define generic text mode numbers so that the user can just give "80x25", "80x60", "132x25"..., rather than "VGA_xxx", to `vidcontrol' to change the current video mode. `vidoio.c' and `vesa.c' will map these numbers to real video mode numbers appropriate and available with the given video hardware. I believe this will be useful to make syscons more portable across archtectures. Notes: svn path=/head/; revision=39591
* Add VESA support to syscons.Søren Schmidt1998-09-151-30/+62

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 <info>' option, where <info> 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.

* 1. Reorganized screen saver related code so that both the LKM screenKazutaka YOKOTA1998-08-031-3/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | saver and splash screen can all work properly with syscons. Note that the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it requires additional code from msmith. - Reorganized the splash screen code to match the latest development in this area. - Delay screen switch in `switch_scr()' until the screen saver is stopped, if one is running, - Start the screen saver immediately, if any, when the `saver' key is pressed. (There will be another commit for `kbdcontrol' to support this keyword in the keymap file.) - Do not always stop the screen saver when mouse-related ioctls are called. Stop it only if the mouse is moved or buttons are clicked; don't stop it if any other mouse ioctls are called. 2. Added provision to write userland screen savers. (Contact me if you are interested in writing one.) - Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to support userland screen savers. 3. Some code clean-ups.

It is smartest to compile a font into your kernel (See LINT), but not mandatory, but apart from the cursor you will see nothing on the screen until you load a font.

Now syscons uses the parameter table even if some bits in the table are different from the current VGA register settings. Even if comp_vgaregs() finds that the BIOS video parameter table looks totally unfamiliar to it, syscons allows the user to change the current video mode to some modes which are based on the VGA 80x25 mode. They are VGA 80x30, VGA 80x50, VGA 80x60. In this case the user will be warned, during boot, that video mode switching is only paritally supported on his machine.

It is SC_HISTORY_SIZE*MAXCONS or 1000*MAXCONS; whichever is larger. CONS_HISTORY will allow the user to set the history size up to SC_HISTORY_SIZE unconditionally (or the current height of the console if it is larger than SC_HISTORY_SIZE). If the user requests a larger buffer, it will be granted only if the total number of all allocated history lines and the requested number of lines won't exceed the maximum. - Don't free the previous history buffer and leave the history buffer pointer holding a invalid pointer. Set the pointer to NULL first, then free the buffer. PR: bin/4592 Notes: svn path=/head/; revision=30662
* Add a new keyboard mode K_CODE. Returns a single byte for each keySøren Schmidt1997-10-011-9/+10
| | | | | | | | | | | much like the scancode mode. However the keys that (for no good reason) returns extension codes etc, are translated into singlebyte codes. Needed by libvgl. This makes life ALOT easier, also the XFree86 folks could use this. Notes: svn path=/head/; revision=30043

| | | | | | | | | | | | | | | size in terms of lines (instead of bytes). When changing video mode in ioctl SW_XXX commands, syscons checks scp->history_size and allocate a history buffer at least as large as the new screen size. (This was unnecessary before, because HISTORY_SIZE was as large as 100 lines and this is bigger than the maximum screen size: 60 lines). Similar adjustment is done in ioctl CONS_HISTORY command too.

* Screen saver related fixes.Kazutaka YOKOTA1997-07-151-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Add new interface, add_scrn_saver()/remove_scrn_saver(), to declare loading/unloading of a screen saver. The screen saver calls these functions to notify syscons of loading/unloading events. It was possible to load multiple savers each of which will try to remember the previous saver in a local variable (`old_saver'). The scheme breaks easily if the user load two savers and unload them in a wrong order; if the first saver is unloaded first, `old_saver' in the second saver points to nowhere. Now only one screen saver is allowed in memory at a time. Soeren will be looking into this issue again later. syscons is becoming too heavy. It's time to cut things down, rather than adding more... 2. Make scrn_timer() to be the primary caller of the screen saver (*current_saver)(). scintr(), scioctl() and ansi_put() update `scrn_time_stamp' to indicate that they want to stop the screen saver. There are three exceptions, however. One is remove_scrn_saver() which need to stop the current screen saver if it is running. To guard against scrn_timer() calling the saver during this operation, `current_saver' is set to `none_saver' early. The others are sccngetc() and sccncheckc(); they will unblank the screen too. When the kernel enters DDB (via the hot key or a break point), the screen saver will be stopped by sccngetc(). However, we have a reentrancy problem here. If the system has been in the middle of the screen saver... (The screen saver reentrancy problem has always been with sccnputc() and sccngetc() in the -current source. So, the new code is doing no worse, I reckon.) 3. Use `mono_time' rather than `time'. 4. Make set_border() work for EGA and CGA in addition to VGA. Do nothing for MDA. Changes to the LKM screen saver modules will follow shortly. YOU NEED TO RECOMPILE BOTH SCREEN SAVERS AND KERNEL AS OF THESE CHANGES. Reviewed by: sos and bde Notes: svn path=/head/; revision=27426
* A fix/work-around for ThinkPad 535.Kazutaka YOKOTA1997-06-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new configuration flag, KBD_NORESET (0x20) to tell scprobe() not to reset the keyboard. IBM ThinkPad 535 has the `Fn' key with which the user can perform certain functions in conjunction with other keys. For example, `Fn' + PageUP/PageDOWN adjust speaker volume, `Fn' + Home/End change brightness of LCD screen. It can also be used to suspend the system. It appears that these functions are implemented at the keyboard level or the keyboard controller level and totally independent from BIOS or OS. But, if the keyboard is reset (as is done in scprobe()), they become unavailable. (There are other laptops which have similar functions associated with the `Fn' key. But, they aren't affected by keyboard reset.) ThinkPad 535 doesn't have switches or buttons to adjust brightness and volume, or to put the system into the suspend mode. Therefore, it is essential to preserve these `Fn' key functions in FreeBSD. The new flag make scprobe() skip keyboard reset. If this flag is not set, scprobe() behaves in the same say as before. (If we only knew a way to detect ThinkPad 535, we could skip keyboard reset automatically, but...) Notes: svn path=/head/; revision=27063
* 1) font loading (two fixes)Kazutaka YOKOTA1997-05-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this.
