How it works:
--
Basically ifs is a copy of ffs, overriding some vfs/vnops. (Yes, hack.)
I didn't see the need in duplicating all of sys/ufs/ffs to get this
off the ground.
File creation is done through a special file - 'newfile' . When newfile
is called, the system allocates and returns an inode. Note that newfile
is done in a cloning fashion:
fd = open("newfile", O_CREAT|O_RDWR, 0644);
fstat(fd, &st);
printf("new file is %d\n", (int)st.st_ino);
Once you have created a file, you can open() and unlink() it by its returned
inode number retrieved from the stat call, ie:
fd = open("5", O_RDWR);
The creation permissions depend entirely if you have write access to the
root directory of the filesystem.
To get the list of currently allocated inodes, VOP_READDIR has been added
which returns a directory listing of those currently allocated.
--
What this entails:
* patching conf/files and conf/options to include IFS as a new compile
option (and since ifs depends upon FFS, include the FFS routines)
* An entry in i386/conf/NOTES indicating IFS exists and where to go for
an explanation
* Unstaticize a couple of routines in src/sys/ufs/ffs/ which the IFS
routines require (ffs_mount() and ffs_reload())
* a new bunch of routines in src/sys/ufs/ifs/ which implement the IFS
routines. IFS replaces some of the vfsops, and a handful of vnops -
most notably are VFS_VGET(), VOP_LOOKUP(), VOP_UNLINK() and VOP_READDIR().
Any other directory operation is marked as invalid.
What this results in:
* an IFS partition's create permissions are controlled by the perm/ownership of
the root mount point, just like a normal directory
* Each inode has perm and ownership too
* IFS does *NOT* mean an FFS partition can be opened per inode. This is a
completely seperate filesystem here
* Softupdates doesn't work with IFS, and really I don't think it needs it.
Besides, fsck's are FAST. (Try it :-)
* Inodes 0 and 1 aren't allocatable because they are special (dump/swap IIRC).
Inode 2 isn't allocatable since UFS/FFS locks all inodes in the system against
this particular inode, and unravelling THAT code isn't trivial. Therefore,
useful inodes start at 3.
Enjoy, and feedback is definitely appreciated!

Now that the new sound code supports MIDI, the major reason we had for
reviving it is gone. It is a far better investment polishing the new
midi code than trying to keep this on life support. Come 5.0-REL, if
there are major shortcomings in the pcm sound driver then maybe we can
rethink this, but until then we should focus on pcm.
Remember, these have not been compilable since ~April-May this year.

Previously, these cards were supported by the lnc driver (and they
still are, but the pcn driver will claim them first), which is fine
except the lnc driver runs them in 16-bit LANCE compatibility mode.
The pcn driver runs these chips in 32-bit mode and uses the RX alignment
feature to achieve zero-copy receive. (Which puts it in the same
class as the xl, fxp and tl chipsets.) This driver is also MI, so it
will work on the x86 and alpha platforms. (The lnc driver is still
needed to support non-PCI cards. At some point, I'll need to newbusify
it so that it too will me MI.)
The Am79c978 HomePNA adapter is also supported.
This provides support for the Adaptec SCSI RAID controller family,
as well as the DPT SmartRAID V and VI families.
The driver will be maintained by Mark and Adaptec, and any changes
should be referred to the MAINTAINER.

MSS/PCI bridge drivers
Midi-tty interface to support general serial devices
Modules
Currently, many drivers support more than one bus of ISA, EISA, MCA,
PCI.
Before this commit, we had, for example, some SCSI devices listed more
than once, iirc, some up to three times (ISA/EISA, MCA, PCI).
Since now the "device" line is common for all of them and they only
differ for the hints stuff, I did the following:
First, list Busses: (E)ISA, MCA, PCI and explain, that only ISA
needs the hints stuff.
Move NIC/SCSI stuff, which were the only split sections, behind these
stuff. Describe all drivers only one time and list all supported
chips.
List all device (+ hints for ISA, if possible).
I've also added few additional supported chips to some drivers, xl for
example and some SCSI drivers.
Also, softupdates is no longer disabled by default, so the comment should
not say, it's not enabled by default due to license issues.

Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.
config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel. You can reconfigure your
isa devices with the likes of this at loader(8) time:
set hint.ed.0.port=0x320
userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.
It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8). See the "hints" directive in GENERIC
as an example.
All device wiring has been moved out of config(8). There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file. If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you. You can also compile in the
hints directly with: hints "device.hints" as well.
There are a few things that I'm not too happy with yet. Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it. However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built. A stack of man4 pages will need updating. :-/
Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated. eg: 'device fe 4' will compile the fe driver with NFE set
to 4. You can then set hints for 4 units (0 - 3). Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this. This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.
Please exercise EXTREME CAUTION when transitioning!

Socket 8 to 370 converters. When (1) CPU_PPRO2CELERON option is
defined, (2) Intel CPU is found and (3) CPU ID is 0x66?, L2 cache is
enabled through MSR 0x11e. The L2 cache latency value can be
specified by CPU_L2_LATENCY option. Default value of L2 cache latency
is 5.
These options are useful if you use Socket 8 to Socket 370 converter
(e.g. Power Leap's PL-Pro/II.) Most PentiumPro BIOSs don't enable L2
cache of Mendocino Celeron CPUs because they don't know Celeron CPUs.
These options are needles if you use a Coppermine (FCPGA) Celeron or
PentiumIII, becuase the L2 cache enable bit is hard wired and L2 cache
is always enabled.
NETGRAPH is not present in GENERIC at the moment. Also, change some
settings to support USB installs:
- Add KBD_INSTALL_CDEV as an option to make /dev/kbd[01] actually work.
- Turn on keyboard probing in sc0. The syscons driver will now use a
flag documented in ukbd(4) but not in sc(4) that tells syscons to
actively search for a keyboard device if none is found. This allows
USB keyboards to just be plugged in and instantly start working.
- Require the atkbd0 driver to actually probe to see if a keyboard is
there. This allows USB keyboards to be seen by sc0 if an AT keyboard
isn't plugged into the computer. This also means that you will no
longer be able to plug an AT keyboard into a machine after it has
booted a GENERIC kernel and use it. AT keyboards aren't designed for
this anyway. USB keyboards are designed for this, and they work.

Be aware of the fact that this driver is very immature and has only been

this is an excellent driver to start playing with.
