Restore binary compatibility for GIO_KEYMAP and PIO_KEYMAP.

2011-07-17T08:19:19Z

Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls to support wide characters. I created a patch to add ABI compatibility for the old calls, but I didn't get any feedback to that. It seems now people are upgrading from 8 to 9 they experience this issue, so add it anyway.

Explicitly tell the compiler that we don't care about the return value

Use proper types in kbdmux_kbd_getc():

- The return value should be a signed integer, because -1 means failure. - The c variable should be unsigned, to force it to be zero-extended when returned. Reported by: Andreas Tobler

Move buffer management into kbd and kbdmux drivers.

2009-06-05T15:19:05Z

These two drivers seem to be the last consumers of clists. clists are quite overengineered for simple circular buffers, so I'm adding similar buffer management routines to the kbd and kbdmux drivers. The input buffer is now part of the softc structures, instead of having dynamically allocated cblocks.

Do not use Giant for kbdmux(4) locking. This is wrong and apparently causing more problems than it solves. This will re-open the issue where interrupt handlers may race with kbdmux(4) in polling mode. Typical symptoms include (but not limited to) duplicated and/or missing characters when low level console functions (such as gets) are used while interrupts are enabled (for example geli password prompt, mountroot prompt etc.) MFC after: 3 days

Since r188030 the error value for attach is returned, this means if kbdmux

fails to attach (possibly due to disable hints) then we get called back for unload. Correctly handle the case where the keyboard isnt found rather than calling panic.

Don't include in non-TTY drivers.

2008-07-24T09:54:10Z

The kbd, kbdmux, ugen and uhid drivers included , because they needed clists, which have been moved to some time ago. In the MPSAFE TTY branch, does not include , which means we have to teach these drivers to include this header file directly. Approved by: philip (mentor, implicit)

Remove explicit calls to keyboard methods with their respective variants

implemented with macros. This patch improves code readability. Reasoning behind kbdd_* is a "keyboard discipline". List of macros is supposed to be complete--all methods of keyboard_switch should have their respective macros from now on. Functionally, this code should be no-op. My intention is to leave current behaviour of code as is. Glanced at by: rwatson Reviewed by: emax, marcel Approved by: cognet
