pooka 6db2b1c100 LFS_KERNEL_RFW 2007-12-13 16:08:12 +00:00
elad 021227aa78 Don't compile lfs_rfw.c, suggested by cube@. 2007-12-12 18:52:00 +00:00
pooka db06a930e6 Remove cn_lwp from struct componentname. curlwp should be used 
from on.  The NDINIT() macro no longer takes the lwp parameter and
associates the credentials of the calling thread with the namei
structure.

ad 4b293a84e1 Interrupt handling changes, in discussion since February: 
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

dsl 956bff160a Temporarily make 'atomic_add_int()' a non-atomic add so the build suceeds. 
At some point the functions will (presumably) make their way into either
libc or libutil.

pooka 21913eabe5 Rototill. 
Ok, ok, a few more words about it: stop holding puffs_cc as a holy
value and passing it around to almost every possible place (popquiz:
which kernel variable does this remind you of?).  Instead, pass
the natural choice, puffs_usermount, and fetch puffs_cc via
puffs_cc_getcc() only in routines which actually need it.  This
not only simplifies code, but (thanks to the introduction of
puffs_cc_getcc()) enables constructs which weren't previously sanely
possible, say layering as a curious example.

There's still a little to do on this front, but this was the major
fs interface blast.

pooka 6a3d9a187d Remove "puffs_cid" from the puffs interface following l-removal 
from the kernel vfs interfaces.  puffs_cc_getcaller(pcc) can be
used now should the same information be desired.

dogcow 1e02f40f0f fallout from the not-quite-complete curlwp removal. 
I'm not sure why I had to monkey about with the includes to get VFS_SYNC to
reappear.

pooka 61e8303e9d Remove the "struct lwp *" argument from all VFS and VOP interfaces. 
The general trend is to remove it from all kernel interfaces and
this is a start.  In case the calling lwp is desired, curlwp should
be used.

quick consensus on tech-kern

pooka 7e0d71a369 Execute I/O in a separate thread for async I/O where previously 
everything was written/read in caller context.

Also, make the "kernel" lock recursive.  It works better that way ...

pooka eabd71f058 Emulate spls by using pthread rwlocks: splfoo() takes a read lock 
and when doing processing in an interrupt (effectively when calling
biodone()), we take the write lock.

pooka 895e09b8c5 Sprinkle some more locking, especially to the vm. Due to some 
additional fixes, it's now possible to run file systems with
spinlocks actually enabled.  The genfs_putpages() locking is still
working only due to greater powers, but I'll eventually get around to
fixing it.

pooka 0be31eefc7 Allocate buf using getiobuf() instead of abusing the stack. 2007-11-04 19:37:29 +00:00
pooka 08ac8063af Fix some comments: thinking of it more closely, it is actually safe 
to release the sleep interlock before calling cv_wait() because we
are protected by the list mutex which prevents a wakeup race.
 2007-11-04 18:46:29 +00:00
pooka 18ae49a27c Make the strategy routine get the results through biowait() and 
the "disk driver" (rumpuser) call biodone() to indicate the completion
of I/O.  Support for B_ASYNC is coming at some point, but I need
more locking support in the emulated vm for that.

code needs to be actually written soon ...
 2007-10-31 16:00:26 +00:00
pooka 87f9ee4c42 Make it possible to run rumps multithreaded. This brings real 
locking and makes it possible to run file systems which create
threads.  It also makes rump file system behaviour better match
file system behaviour in the kernel.

pooka 6640f4d32a It's non-trivial to say that "no, we don't have cpu counter on this 
arch (rump)", so emulate it.  But this is suboptimal.  The crux of
the problem seems to be that types.h contains both information on
the machine architecture (which we want) as well as other defines
such as __HAVE_CPU_COUNTER (which we don't want).
