used in ioctl routines to do the right thing when the FKIOCTL flag is
passed to the IOCTL routine indicating its a in-kernel VOP_IOCTL call and
indirect addresses provided in the arguments are to be seen as kernel
adresses rather than userland adresses.
A simple substitution and prepending of the `flags' passed on to the ioctl
handler is enough to DTRT.
- Add a booted_wedge variable that indicates the wedge that was booted
from. If this is NULL, booted_partition is consulted.
- Adjust setroot() and its support routines for root-on-wedges. Could
use some tidy-up, but this works for now.
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
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
possible to use alternate system call tables. This is usefull for
displaying correctly the arguments in Mach binaries traces.
If NULL is given, then the regular systam call table for the process is used.
the most "officially looking" is IEC 60027-2, ie "Ki", "Mi", ...,
which is not too popular, and which would require more code changes.
So stick with the traditional capital "K" for (divisor==1024), and use
the SI "k" otherwise (ie (divisor==1000)).
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.
easy, convenient dropping into DDB at the "root device: " prompt.
Useful if your console can't do it w/o actually taking an interrupt
and you want to, say, look at the boot messages.
