* Serialize output routine of terminal emulator (te_puts()) by a lock.Hidetoshi Shimokawa2007-09-202-1/+14
| | | | | | | | | | | | | | | | | - The output routine of low level console is not protected by any lock by default. - Increment and decrement of sc->write_in_progress are not atomic and this may cause console hang. - We also have many other states used by emulator that should be protected by the lock. - This change does not fix interspersed messages which PRINTF_BUFR_SIZE kernel option should fix.

It was possible to get into the endless loop when attempting to switch to a closed vty (which is not allowed and beep-alerted when attempted) and when the visual beep was in effect.

* Fix our ioctl(2) implementation when the argument is "int". NewRuslan Ermilov2006-09-272-7/+108
| | | | | | | | | | | | | | | | ioctls passing integer arguments should use the _IOWINT() macro. This fixes a lot of ioctl's not working on sparc64, most notable being keyboard/syscons ioctls. Full ABI compatibility is provided, with the bonus of fixing the handling of old ioctls on sparc64.

* Introduce a spinlock for synchronizing access to the video output hardwareScott Long2006-09-133-19/+38
| | | | | | | | | | | | in syscons. This replaces a simple access semaphore that was assumed to be protected by Giant but often was not. If two threads that were otherwise SMP-safe called printf at the same time, there was a high likelyhood that the semaphore would get corrupted and result in a permanently frozen video console.

* APM was calling the suspend process from a timeout. This meant thatWarner Losh2006-05-251-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | other timeouts could not happen while suspending, including timeouts for things like msleep. This caused the system to hang on suspend when the cbb was enabled, since its suspend path powered down the socket which used a timeout to wait for it to be done. APM now creates a thread when it is enabled, and deletes the thread when it is disabled. This thread takes the place of the timeout by doing its polling every ~.9s. When the thread is disabled, it will wakeup early, otherwise it times out and polls the varius things the old timeout polled (APM events, suspend delays, etc). This makes my Sony VAIO 505TS suspend/resume correctly when APM is enabled (ACPI is black listed on my 505TS). This will likely fix other problems with the suspend path where drivers would sleep with msleep and/or do other timeouts. Maybe there's some special case code that would use DELAY while suspending and msleep otherwise that can be revisited and removed.

* Integrate kbdmux(4) into syscons(4) and kbd code.Maksim Yevmenkin2006-02-281-4/+42
| | | | | | | | | | | | | | | | | | | | | | | By default syscons(4) will look for the kbdmux(4) keyboard first, and then, if not found, look for any keyboard. Current kbd code is modified so if kbdmux(4) is the current keyboard, all new keyboards are automatically added to the kbdmux(4). Switch to kbdmux(4) can be done at boot time, by loading kbdmux module at the loader prompt, or at runtime, by kldload'ing the kbdmux module and releasing current active keyboard. If, for whatever reason, kbdmux(4) is not required/desired then just do not load it and everything should work as before. It is also possible to kldunload kbdmux at runtime and syscons(4) will automatically switch to the first available keyboard.

| | | | | | | | | | | | | | | | | | | and do some preparations for handling 12x22 fonts (currently lots of code implies and/or hardcodes a font width of 8 pixels). This will be required on sparc64 which uses a default font size of 12x22 in order to add font loading and saving support as well as to use a syscons(4)-supplied mouse pointer image. This API breakage is committed now so it can be MFC'ed in time for 6.0 and later on upcoming framebuffer drivers destined for use on sparc64 and which are expected to rely on using font loading internally and on a syscons(4)-supplied mouse pointer image can be easily MFC'ed to RELENG_6 rather than requiring a backport.

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.

| | | | | | | | | | | | | | | 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.
