* Remove the source to digi(4).John Baldwin2017-04-251-1560/+0

* sys/dev: use our nitems() macro when it is avaliable through param.h.Pedro F. Giffuni2016-04-191-2/+2
| | | | | | | | | | No functional change, only trivial cases are done in this sweep, Drivers that can get further enhancements will be done independently. Discussed in: freebsd-current Notes: svn path=/head/; revision=298307
* Fix our ioctl(2) implementation when the argument is "int". NewRuslan Ermilov2006-09-271-1/+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.

* - Push Giant down into linker_reference_module().John Baldwin2006-06-201-3/+3
| | | | | | | | | | | - 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 defaultPoul-Henning Kamp2004-10-181-16/+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.

| | | | | | | | | | | | future: rename ttyopen() -> tty_open() and ttyclose() -> tty_close(). We need the ttyopen() and ttyclose() for the new generic cdevsw functions for tty devices in order to have consistent naming. Notes: svn path=/head/; revision=132226
* Give kldunload a -f(orce) argument.Poul-Henning Kamp2004-07-131-2/+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. Notes: svn path=/head/; revision=132117

| | | | | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags. Notes: svn path=/head/; revision=126080

Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer.

* Use the PCI port for pci cards, not just for PCIXR cards.Brian Somers2002-04-101-6/+6
| | | | | | | | | | | Add the card name to the error message for the first initialisation failure, giving us more info about what was actually discovered. This code has been tested by Robert Suetterlin <robert@mpe.mpg.de> to work on a PCI Xem card. Notes: svn path=/head/; revision=94323
* Change linker_reference_module() so that it's passed a structBrian Somers2002-04-101-2/+8
| | | | | | | | | | | | | mod_depend * (which may be NULL). The only consumer of this function at the moment is digi_loadmoduledata(), and that passes a NULL mod_depend *. In linker_reference_module(), check to see if we've already got the required module loaded. If we have, bump the reference count and return that, otherwise continue the module search as normal. Notes: svn path=/head/; revision=94321
* Add some missing MODULE_VERSIONsBrian Somers2002-04-101-0/+2
| | | | | | | | Without these, the kern_linker interface doesn't record these pseudo-drivers, making them unavailable via modlist_lookup2*(). Notes: svn path=/head/; revision=94320
* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-3/+3
| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.
