yamt 91ae756395 - for some ports, especially for ones without pmap_growkernel, 
buf_memcalc is used by bootstrap as well.  fix NULL dereference for them.
- limit kva usage for each cache to 20% of vm_map.  XXX a bit arbitrary.
- add a comment.

rmind 42c415f8f1 pool_cache_init: Remove the alignment of pc according to the CACHE_LINE_SIZE, 
which is not useful for rump.  This fixes the pool_cache_destroy() which was
freeing the modified pointer, instead of the original one.

OK by <pooka>.

yamt c3c197ba35 when calculating some cache sizes, consider the amount of available kva.

pooka 0b82eddb8b Reorder a few init bits into a better order to make syspuffs work again. 2008-03-18 15:16:22 +00:00
pooka 546bf50253 Cache referenced rootvp in struct ukfs. Makes it possible to run 
pre/postcall wrapper around the exported namei, since postcall no
longer needs to execute VFS_ROOT (which is a bad thing to do while
potentially holding on to a locked vnode, mmkay).
 2008-03-13 14:24:30 +00:00
pooka e8401439ac Implement all ukfs interfaces (except getdents, that's a bit more 
tricky) with the help of rump system calls instead of calling namei
by themselves.  Trust me when I say it was non-trivial to get the
namei calls right.
 2008-03-12 21:37:15 +00:00
pooka b590aae6d8 Support chdir. This is useful for example when testing and not 
wanting to stress namei() so much as test individual ops.
XXX: it should be implemented per calling thread, not per fs.

pooka 8ca4306537 Support multiple file systems within one process with ukfs by using 
a "chroot" for each file system.

krwlock_t. This is a step towards removing lockmgr and simplifying
vnode locking. Discussed on tech-kern.

pooka 2ff7c33801 honor pager locking protocol in uao_detach() 2008-01-27 20:10:53 +00:00
pooka 18e91c156a Don't fool around when recycling vnodes, simply override refcount 
to 1, hold on tight to your hat, and call recycle.  The reason is
that we might pick up extra references such as from lookup and we
don't really care about tracking those.  For example with p2k,
puffs in the kernel already does all the refcounting we could ever
dream of, and therefore it's left to the client and unnecessary.

pooka fb3107360b Use vfs_subr.c from sys/kern. This brings differences in the vnode 
life cycle between rump and a real kernel to a minimum.

pooka 22b1964406 Include vfs_getcwd.c too. It isn't used currently, but it's linked. 2008-01-25 06:42:29 +00:00
pooka 2b1b5d29b8 Use namei() etc. from kernel sources instead of a reimplementation. 
To accommodate, give the rootvnode its own vnode op vector with a
simple lookup operation.  This is used for looking up the file
system's device vnode instead of doing that directly in a homesmoked
namei().

pooka daadf5acef Make work again by repairing spec_node_init() and not being afraid 
to use it.
 2008-01-24 20:06:46 +00:00
ad 703069c0e9 specfs changes for PR kern/37717 (raidclose() is no longer called on 
shutdown). There are still problems with device access and a PR will be
filed.

- Kill checkalias(). Allow multiple vnodes to reference a single device.

- Don't play dangerous tricks with block vnodes to ensure that only one
  vnode can describe a block device. Instead, prohibit concurrent opens of
  block devices. As a bonus remove the unreliable code that prevents
  multiple file system mounts on the same device. It's no longer needed.

- Track opens by vnode and by device. Issue cdev_close() when the last open
  goes away, instead of abusing vnode::v_usecount to tell if the device is
  open.

pooka d25a6ab97f Don't use PAGE_SIZE when faking physmem, as it's not always available 
at compile-time.  We could init it runtime, but it's just a random
number anyway.
 2008-01-24 15:02:16 +00:00
pooka 9af1c338e2 Default physmem was too tight, increase to 256megs from 0 bytes. 2008-01-24 08:34:49 +00:00
pooka 2310c71b91 Until debugging threaded programs in NetBSD is fixed, supply the 
cpp option RUMP_WITHOUT_THREADS as a workaround.  If defined, it
makes rump itself operate single-threaded and prevents kthread_create()
from working.
 2008-01-22 09:23:39 +00:00
pooka 65a36d9ef8 In case cv_timedwait() gets ticks == 0, make sure we sleep eternally 
(or at least until wakeup) instead of immediately waking up.

In other words, fix this after it broke when another piece of the
code was fixed.  Ain't programming fun?
