* Add better support for larger I/O clusters, including larger physicalJohn Dyson1998-01-243-5/+8

* VM level code cleanups.John Dyson1998-01-223-75/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Start using TSM. Struct procs continue to point to upages structure, after being freed. Struct vmspace continues to point to pte object and kva space for kstack. u_map is now superfluous. 2) vm_map's don't need to be reference counted. They always exist either in the kernel or in a vmspace. The vmspaces are managed by reference counts. 3) Remove the "wired" vm_map nonsense. 4) No need to keep a cache of kernel stack kva's. 5) Get rid of strange looking ++var, and change to var++. 6) Change more data structures to use our "zone" allocator. Added struct proc, struct vmspace and struct vnode. This saves a significant amount of kva space and physical memory. Additionally, this enables TSM for the zone managed memory. 7) Keep ioopt disabled for now. 8) Remove the now bogus "single use" map concept. 9) Use generation counts or id's for data structures residing in TSM, where it allows us to avoid unneeded restart overhead during traversals, where blocking might occur. 10) Account better for memory deficits, so the pageout daemon will be able to make enough memory available (experimental.) 11) Fix some vnode locking problems. (From Tor, I think.) 12) Add a check in ufs_lookup, to avoid lots of unneeded calls to bcmp. (experimental.) 13) Significantly shrink, cleanup, and make slightly faster the vm_fault.c code. Use generation counts, get rid of unneded collpase operations, and clean up the cluster code. 14) Make vm_zone more suitable for TSM. This commit is partially as a result of discussions and contributions from other people, including DG, Tor Egge, PHK, and probably others that I have forgotten to attribute (so let me know, if I forgot.) This is not the infamous, final cleanup of the vnode stuff, but a necessary step. Vnode mgmt should be correct, but things might still change, and there is still some missing stuff (like ioopt, and physical backing of non-merged cache files, debugging of layering concepts.)

| | | | | | | | | | | | | Move sigjmp_buf and jmp_buf structure definitions to machine/setjmp.h so that i386 can continue to use int as the basic register type and alpha can use long. Bruce was concerned about possible differing alignment. I've left the definition of _JBLEN in machine/setjmp.h even though Bruce's example used the number directly. I don't know if any other code relies on _JBLEN, so I left it to avoid potential breakage. Notes: svn path=/head/; revision=32641

* Added accent (dead) key support to syscons and kbdcontrol.Kazutaka YOKOTA1998-01-073-7/+393
| | | | | | | | | | | | | | | | | | | | | | | | | | With a keymap with accent key definitions loaded to syscons, you press an accent key followed by a regular letter key to produce an accented letter. Press an accent key followed by the space bar to get the accent letter itself. Code is based on the ideas and work by jmrueda@diatel.upm.es and totii@est.is. PR: i386/4016 console.h - Defined structures and constants for accent (dead) keys. syscons.c, kbdtables.h - When an accent key is pressed, set the corresponding index to `accents'. If the next key is the space key, produce the accent char itself. Otherwise search the accent key map entry, indexed by `accents', for a matching pair of a regular char and an accented char. - Added ioctl functions to set and get the accent key map (PIO_DEADKEYMAP and GIO_DEADKEYMAP).

* Make our v_usecount vnode reference count work identically to theJohn Dyson1998-01-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | original BSD code. The association between the vnode and the vm_object no longer includes reference counts. The major difference is that vm_object's are no longer freed gratuitiously from the vnode, and so once an object is created for the vnode, it will last as long as the vnode does. When a vnode object reference count is incremented, then the underlying vnode reference count is incremented also. The two "objects" are now more intimately related, and so the interactions are now much less complex. When vnodes are now normally placed onto the free queue with an object still attached. The rundown of the object happens at vnode rundown time, and happens with exactly the same filesystem semantics of the original VFS code. There is absolutely no need for vnode_pager_uncache and other travesties like that anymore. A side-effect of these changes is that SMP locking should be much simpler, the I/O copyin/copyout optimizations work, NFS should be more ponderable, and further work on layered filesystems should be less frustrating, because of the totally coherent management of the vnode objects and vnodes. Please be careful with your system while running this code, but I would greatly appreciate feedback as soon a reasonably possible. Notes: svn path=/head/; revision=32286
