* Remove unused files from the digi(4) driver.ed2009-01-164-14961/+0
| | | | | | | | | | | | The digi(4) driver directory contains some files that cannot be checked out on Windows filesystems. This isn't a big deal, but the files aren't used anyway. There are still some other places where checkouts on Windows don't work, such as VFS_MOUNT.9/vfs_mount.9. This should already be a small improvement. MFC after: 1 month
* Fix our ioctl(2) implementation when the argument is "int". Newru2006-09-271-1/+12
| | | | | | | | | | | | | 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. Reviewed by: bde (with contributions) Tested by: emax, marius MFC after: 1 week

| | | | | | | | - Add a new function linker_release_module() as a more intuitive complement to linker_reference_module() that wraps linker_file_unload(). linker_release_module() can either take the module name and version info passed to linker_reference_module() or it can accept the linker file object returned by linker_reference_module().

* Add new function ttyinitmode() which sets our systemwide defaultphk2004-10-181-16/+1
| | | | | | | | | | | | | | 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.

* Give kldunload a -f(orce) argument.phk2004-07-131-2/+2
| | | | | | | | | | | | | | | | | Add a MOD_QUIESCE event for modules. This should return error (EBUSY) of the module is in use. MOD_UNLOAD should now only fail if it is impossible (as opposed to inconvenient) to unload the module. Valid reasons are memory references into the module which cannot be tracked down and eliminated. When kldunloading, we abandon if MOD_UNLOAD fails, and if -force is not given, MOD_QUIESCE failing will also prevent the unload. For backwards compatibility, we treat EOPNOTSUPP from MOD_QUIESCE as success. Document that modules should return EOPNOTSUPP for unknown events.

The pessimization is tiny compared with i/o port slowness except on very old machines, but code that used signed short types for i/o ports was unpessimized long ago, and the macro that detected it recently started working for u_short types too. Use of bus space should have made this moot long ago. Not tested at runtime by: bde
