* Add support for VESA mode 0x102 (800x600x4) in syscons. You can activatePoul-Henning Kamp1998-02-122-60/+104
| | | | | | | | | | | | | | | this using option "-b" to the boot blocks. 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. This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported graphics hardware. A number of buglets in the cursor handling in syscons may become visible this way.

If the console enters the `unknown' graphics mode via the ioctl KDSETMODE (KD_GRAPHICS), these fields are not set (because syscons cannot know the correct values), but set_mouse_pos() need to refer to these field to adjust the mouse position. - Turn off MOUSE_VISIBLE when switching video mode by ioctl. - another new option: SC_MOUSE_CHAR Define the first character code of four consecutive codes to be used for the mouse cursor. Default codes are 0xd0 through 0xd3. Beware that if you decide to use any codes outside the range of 0xc0-0xdf, the mouse cursor may not look good, because of the way VGA displays characters in 9-dot-wide character cells. Requested by several people. (This patch was tested by a person who recently reported, in the -current ML, a page fault problem in the kernel (draw_mouse_iamge()) after X server shutdown.

The name of the detected model will be printed at boot time. - A set of new ioctl functions are added to the `psm', `mse' and `sysmouse' drivers so that the userland program (such as the X server) can query device information and change driver settings. - The wheel/roller movement is handled as the `Z' axis movement by the mouse drivers and the moused daemon. The Z axis movement may be mapped to another axis movement or buttons. - The mouse drivers support a new, standard mouse data format, MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement and up to 10 buttons. /sys/i386/include/mouse.h - Added some fields to `mousestatus_t' to store Z axis movement and flag bits. - Added the field `model' to `mousehw_t' to store mouse model code. Defined model codes. - Extended `mousemode_t'. - Added new protocols and some constants for them. - Added new ioctl functions and structures. - Removed obsolete ioctl definitions. /sys/i386/include/console.h - Added `dz' field to the structure `mouse_data' to pass Z axis movement to `syscons/sysmouse'. - Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON. Use button bits defined in `mouse.h' instead. /sys/i386/isa/psm.c - Added a set of functions to detect various mice which have additional features (wheel and buttons) unavailable in the standard PS/2 mouse. - Refined existing ioctl functions and added new ones. Most important of all is MOUSE_SETLEVEL which manipulates the output level of the driver. While the output level remains zero, the output from the `psm' driver is in the standard PS/2 mouse format (three bytes long). When the level is set to one, the `psm' driver will send data in the extended format. At the level two the driver uses the format which is native to the connected mouse is used. (Meaning that the output from the device is passed to the caller as is, unmodified.) The `psm' driver will pass such extended data format as is to the caller if the output level is two, but emulates the standard format if the output level is zero. - Added kernel configuration flags to set initial resolution (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL). - Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION. Acceleration ratio is now specified by the kernel configuration flags stated above. Sync check logic is refined and now standard. The sync check can be turned off by the new kernel configuration flags PSM_CONFIG_NOCHECKSYNC (0x100). PSM_EMULATION has been of little use. - Summer clean up :-) Removed unused code and obsolete comments. /sys/i386/isa/mse.c - Created mseioctl() to deal with ioctl functions MOUSE_XXXX. Most importantly, the MOUSE_SETLEVEL ioctl will change the output format from the 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Use constants defined in `mouse.h' rather than magic numbers. /sys/i386/isa/syscons.c - Changed scioctl() to reflect the new `console.h' and some of the new ioctls defined in `mouse.h'. Most importantly, the MOUSE_SETLEVEL ioctl will change the `sysmouse' output format from the MouseSystems 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Added support for double/triple click actions of the left button and single click action of the right button in the virtual console. The left button double click will select a word under the mouse pointer. The triple click will select a line and the single click of the right button will extend the selected region to the current position of the mouse pointer. This will make the cut/paste support more compatible with xterm. /sys/i386/isa/kbdio.h - Added PSM_INTELLI_ID. Notes: svn path=/head/; revision=31603

* Screen saver related fixes.Kazutaka YOKOTA1997-07-152-37/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

The destructive cursor produced noticeable overhead on the system. It was caused by draw_cursor_image() calling set_destructive_cursor() every so often. set_destructive_cursor() absolutely needs to be called when a) the character code under the cursor has changed either because the cursor moved or because the screen was updated or the mouse pointer overlapped the cursor. b) Or a new font has been loaded, c) or the video mode has been changed, d) or the cursor shape has been changed, e) or the user switched virtual consoles. 2. Turn off the configuration flag CHAR_CURSOR (destructive cursor) in scattach() if we have a non-VGA card. The destructive cursor works only for VGA. 3. Removed redundant calls to set_destructive_cursor() in some places. 4. Fixed the "disappearing mouse pointer" problem. The mouse pointer looked hidden under the destructive cursor when it overlaped the cursor. A slightly different version of the patch was reviewd and OKed by sos and ache.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

If there is no dispaly adapter, the console driver cannot be any good... In this patch, scinit() is split into two parts; the first part is now called scvidprobe() which will detect the presence of video card at the CGA or MONO buffer address and returns TRUE if found. It is called during sccnprobe() and scprobe(). Both will fail if no video card is found. The second part, whose name stays the same as before, scinit(), is called from sccninit() and scattach() to complete initialization of the found video card. The keyboard probe code is moved from scprobe() to sckbdprobe(); scprobe() now calls scvidprobe() and sckbdprobe() to carry out device probe. (This is rather a cosmetic change, but it sure makes the code look better organized.) The problem pointed out by Joerg. Notes: svn path=/head/; revision=26807

* 1) font loading (two fixes)Kazutaka YOKOTA1997-05-152-22/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
