a4db49537b Replace ffind_* with fget calls.
Make fget MPsafe.

Make fgetvp and fgetsock use the fget subsystem to reduce code bloat.

Push giant down in fpathconf().

426da3bcfb SMP Lock struct file, filedesc and the global file list.
Seigo Tanimura (tanimura) posted the initial delta.

I've polished it quite a bit reducing the need for locking and
adapting it for KSE.

Locks:

1 mutex in each filedesc
   protects all the fields.
   protects "struct file" initialization, while a struct file
     is being changed from &badfileops -> &pipeops or something
     the filedesc should be locked.

1 mutex in each struct file
   protects the refcount fields.
   doesn't protect anything else.
   the flags used for garbage collection have been moved to
     f_gcflag which was the FILLER short, this doesn't need
     locking because the garbage collection is a single threaded
     container.
  could likely be made to use a pool mutex.

1 sx lock for the global filelist.

struct file *	fhold(struct file *fp);
        /* increments reference count on a file */

struct file *	fhold_locked(struct file *fp);
        /* like fhold but expects file to locked */

struct file *	ffind_hold(struct thread *, int fd);
        /* finds the struct file in thread, adds one reference and
                returns it unlocked */

struct file *	ffind_lock(struct thread *, int fd);
        /* ffind_hold, but returns file locked */

I still have to smp-safe the fget cruft, I'll get to that asap.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

93cd41f72d Zap silly #if NPCI > 0 and the hoops that we jump through for the module
case.  Use an 'and' case in conf/files so that it only gets compiled if
pci is present.

67072510e8 Added some handling code to work with SLI configs, and removed some unused
older code that was phased out but not removed, heh.

a436a79744 Removed detection for Voodoo Banshee and Voodoo3 cards. I forsee certain
possible complications with the forthcoming DRI code, and feel that DRI
should handle the device-level interaction. Read
http://people.FreeBSD.org/~cokane/3dfx.html
to find out more. Basically want to move toward using OpenGL and DRI for
everything on these cards. Added a few defines and spacing style fixes in
tdfx_vars.h

9a63bf73d2 Bring tdfx_pci.c in sync with some patches I have been testing. Adds better
stability for the Voodoo3/Banshee cards than there was before. Still has a
little way to go before it is completely fixed for those cards though.

48f6bffc18 Studied the tech docs for the Voodoo3 and Banshee, and hopefully fixed the
errors that plagued those cards with XFree86 4.0. They have two memory
ranges as well as an IO port range to them. Also cleaned up the three
warning messages that I got, from inb(), outb() and linuxulator. Also, I
noticed that the DRI and Glide support for the Voodoo4 and 5 has been
placed upon linux.3dfx.com, too bad they haven't released the tech docs
yet. Apparently, they are still pushing glide for all of us, so I will try
and add support once those tech docs are up.

7e23685d60 Stupid me, I put the opt_tdfx.h underneath a test for TDFX_LINUX, which
resides in opt_tdfx. I also cleand up that large define. Compile, tell me
if it does, and I'll re-enable the tdfx entry in the makefile.

f9c078dffe First import of my 3dfx voodoo driver. Currently it supports the Voodoo Graphics and Voodoo2 perfectly. It works just like the 3dfx driver does for linux, by using a character device at /dev/3dfx of Major 107 to provide a window into the 3dfx card's memory space. This interface is used by glide and mesa as far as i know, and probably some other libraries too.
