- Add a wsevent_inject function that atomically adds a set of events to an
event queue and change all code that directly messed with a queue to use it.
- Replace the WSEVENT_WAKEUP macro with a regular function.
- Make WSEVENT_QSIZE, PWSEVENT and splwsevent private definitions to
wsevent.c, instead of exposing them in the header file.
- Make the wsevent_init function take a process to attach to the queue,
instead of leaving this task to the caller (which always did it).
Reviewed in tech-kern@.
* introduce fsetown(), fgetown(), fownsignal() - this sets/retrieves/signals
the owner of descriptor, according to appropriate sematics
of TIOCSPGRP/FIOSETOWN/SIOCSPGRP/TIOCGPGRP/FIOGETOWN/SIOCGPGRP ioctl; use
these routines instead of custom code where appropriate
* make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN
properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP
in sys_ioctl() & sys_fcntl()
* also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and
pass the ioctls down to soo_ioctl() as any other ioctl
change discussed on tech-kern@
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
many bugs have been fixed).
Changes:
The wskbd, wsmouse, and wsmux are now "sub-classes" of wsevsrc, which is
a source of ws events. This make the structure of those drivers a little
more uniform.
Many bug fixes involving adding and removing devices from muxes.
When a kernel is configured without wsmux there will now be none (unlike
before where you got a console mux anyway).
The kernel now compiles with all combinations of ws devices present.
* Allow the wsmux used by wsdisplay for the keyboard(s) to be explicitely
specified with the kbdmux locator.
* Allow keyboards and mice that have a mux to be opened in the regular way.
These changes should be totally backwards compatible.
FIOASYNC ioctrl command had been forwarded from wsmux to each mouse devices
and the devices had set their own event queue async mode. But no one had took
care of the event queue's mode of wsmux itself. Wsmux should make it's own
event queue async mode when it receive FIOASYNC command.
