* Device megapatch 4/6:phk2004-02-211-1/+2
| | | | | | | | 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.
* Device megapatch 3/6:phk2004-02-211-2/+0
| | | | | | | | | | | | Add missing D_TTY flags to various drivers. Complete asserts that dev_t's passed to ttyread(), ttywrite(), ttypoll() and ttykqwrite() have (d_flags & D_TTY) and a struct tty pointer. Make ttyread(), ttywrite(), ttypoll() and ttykqwrite() the default cdevsw methods for D_TTY drivers and remove the explicit initializations in various drivers cdevsw structures.
* Device megapatch 1/6:phk2004-02-211-2/+0
| | | | | | | Free approx 86 major numbers with a mostly automatically generated patch. A number of strategic drivers have been left behind by caution, and a few because they still (ab)use their major number.

* Don't use pessimal (u_short) types for i/o ports. This is mainly forbde2003-08-051-2/+2
| | | | | | | | | | completenss. 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
* Make nokqfilter() return the correct return value.phk2003-03-031-1/+1
| | | | Ditch the D_KQFILTER flag which was used to prevent calling NULL pointers.
* Gigacommit to improve device-driver source compatibility betweenphk2003-03-031-14/+10
| | | | | | | | | | | | | branches: Initialize struct cdevsw using C99 sparse initializtion and remove all initializations to default values. This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386. Approved by: re(scottl)

| | | | | | | | 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.

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.
* Add some missing MODULE_VERSIONsbrian2002-04-108-0/+9
| | | | | Without these, the kern_linker interface doesn't record these pseudo-drivers, making them unavailable via modlist_lookup2*().
* Change the suser() API to take advantage of td_ucred as well as do ajhb2002-04-011-3/+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. Discussed on: smp@

The initial state and lock devices are normally used to set and/or lock ALTPIN settings although the device itself may also be used. ALTPIN settings are applied per-device and apply to both the callin and callout device at the same time.

This driver supports PCI Xr-based and ISA Xem Digiboard cards. dgm will go away soon if there are no problems reported. For now, configuring dgm into your kernel warns that you should be using digi. This driver is probably close to supporting Xi, Xe and Xeve cards, but I wouldn't expect them to work properly (hardware donations welcome). The digi_* pseudo-drivers are not drivers themselves but contain the BIOS and FEP/OS binaries for various digiboard cards and are auto-loaded and auto-unloaded by the digi driver at initialisation time. They *may* be configured into the kernel, but waste a lot of space if they are. They're intended to be left as modules. The digictl program is (mainly) used to re-initialise cards that have external port modules attached such as the PC/Xem.
