* kbdmux(4) keyboard multiplexer integrationMaksim Yevmenkin2005-07-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | o Add two new ioctl's KBADDKBD and KBRELKBD. These are used to add and remove keyboard to (and from) kbdmux(4) keyboard multiplexer; o Introduce new kbd_find_keyboard2() function. It does exactly the same job as kbd_find_keyboard() function except it allows to specify starting index. This function can be used to iterate over keyboards array; o Re-implement kbd_find_keyboard() as call to kbd_find_keyboard2() with starting index of zero; o Make sure syscons(4) passed KBADDKBD and KBRELKBD ioctl's onto currently active keyboard. These changes should not have any visible effect. MFC after: 1 week Notes: svn path=/head/; revision=147980
* Fix syscons on amd64. The SC_PIXEL_MODE commit from May 29th added a newPeter Wemm2005-06-142-4/+4
| | | | | | | | | | | | | | | function pointer to the vga render dispatch table and initialized it with vga_nop. The problem is that vga_nop() is a varargs function, and the table declares a non-varargs function pointer. On amd64 (and I think ppc), mixing varargs and non-varargs function pointers is fatal. Change vga_nop() and gfb_nop() from varargs to non-varargs do-nothing functions. This stops the stack corruption that only happened on amd64.

| | | | | | | | | | | | | | | | | | | | | | | | 24, and 32 bit modes. To use that, syscons(4) must be built with the compile time option 'options SC_PIXEL_MODE', and VESA support (a.k.a. vesa.ko) must be either loaded, or be compiled into the kernel. Do not return EINVAL when the mouse state is changed to what it already is, which seems to cause problems when you have two mice attached, and applications are not likely obtain useful information through the EINVAL caused by showing the mouse pointer twice. Teach vidcontrol(8) about mode names like MODE_<NUMBER>, where <NUMBER> is the video mode number from the vidcontrol -i mode output. Also, revert the video mode if something fails.

* Add new function ttyinitmode() which sets our systemwide defaultPoul-Henning Kamp2004-10-182-26/+21
| | | | | | | | | | | | | | | | | modes on a tty structure. Both the ".init" and the current settings are initialized allowing the function to be used both at attach and open time. The function takes an argument to decide if echoing should be enabled. Echoing should not be enabled for regular physical serial ports unless they are consoles, in which case they should be configured by ttyconsolemode() instead. Use the new function throughout.

| | | | | | | | | | | | | want a splash screen. There seems to be some confusion in the syscons code as to the meaning of the SC_KERNEL_CONSOLE flag. Its absence is sometimes interpreted to mean "I am not the system console", and sometimes to mean "I am not the only VGA console" (see the font loading code for an example of the latter). Someone with better syscons fu than myself should take a closer look. Notes: svn path=/head/; revision=133186

| | | | | | | | | | | | | | | | | | | | | it's in the way even more. Basicly: remove all alpha specific console support from gfb(4), sio(4) and syscons(4). Rewrite the alpha console initialization to be identical to all other platforms. In a nutshell: call cninit(). The platform specific code now only sets or clears RB_SERIAL and thus automaticly causes the right console to be selected. sio.c: o Replace the remote GDB hacks and use the GDB debug port interface instead. o Make debugging code conditional upon KDB instead of DDB. o Call kdb_alt_break() instead of db_alt_break(). o Call kdb_enter() instead of breakpoint(). o Remove the ugly compatibility of using the console as the debug port.

| | | | | | | | | | | | | | | | | | | | | | on architectures that need to call cninit() before the machine is ready to support mutexes (required by make_dev()). - Remove make_dev() call from scinit() when flags indicate unit is the system console, rely on sc_attach_unit() to handle it. - When trying to access current screen's status (scr_stat structure) use the static one provided for the initial system console if no dev_t is available. - When calling make_dev() in sc_attach_unit() catch special case of system's initial console and set up dev_t structure to include pointer to console's scr_stat struct.
