thorpej 5b39541e48 New generic disk framework. Highlights:
- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

traditional usage.

thorpej 17eb6e2bc1 Move the old-style disk instrumentation "structures" to a central location
(sys/kern/subr_disk.c) and note that they should/will be deperecated.

cgd 6652367efa (1) undef various EXEC_ cpp symbols before defining them, in case
they're already defined for some reason (this can happen
        on the alpha, for example, which needs to define EXEC_ECOFF
        in the std.alpha config file).
(2) minor spacing consistency.

mycroft af942a9add Only expect vm_fork() to return if __FORK_BRAINDAMAGE is defined.
Use splstatclock() rather than splhigh() in one place.
Eliminate unused third arg to vm_fork().

cgd a321588516 update for new syscalls.master 1995-11-22 23:09:26 +00:00
cgd a2ce90f34c change definition of profil() to make it 64-bit friendly. This has
no practical consequence on 32-bit systems.  old prototype was
int profil(char *, int, int, int), and new one is int profile(char *,
size_t, u_long, u_int).  the size_t is the size of the buffer,
and the u_long is the 'starting offset'.  (I changed the last int
to u_int, because it's treated as a u_int everywhere, and isn't
logically a signed value.)

cgd e9d17d38b5 avoid unnecessary aging of buffers. This used to make sense, when buffer

christos 7de0fcfd12 Add KTR_EMUL to indicate a switch between syscall emulations.
Currently this record is emitted only on exec. Maybe it should
be emitted on ktrace() attach too.
1995-07-19 15:19:08 +00:00
cgd f5bbdfba41 bdwrite() should upgrade writes to tape devices by sending them to
bawrite().  it's logically more correct (doesn't return an error code,
because it's async; bdwrite is also async), it still writes things
in-order, it makes sure the proper accountins is done (see the
wasdelayed cases in bwrite()), and it allows writes to vnodes on volumes
mountd with the MNT_ASYNC to be converted into delayed writes the way
God, err, Kirk intended.  Convert synchronous bwrite()s on MNT_ASYNC
file systems to delayed writes.

cgd 9c3fe30d92 fix long-standing XXX in getblk(): NFS does funky things (somewhat
explained in comments), which can cause a race condition.  amazingly,
the _only_ time i've ever seen or heard of this problem was in some
comments and sources by Rick Macklem, and when running against the
a DEC OSF/1 NFS server running on an Alpha.

mycroft 7263209ce6 Make each disk and tape driver define its own read and write functions.

cgd 3d9ffd41f3 make this work sanely on a 64-bit machine. Sacrifices a small bit of
