DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic. Intended
for machines where debug on panic is useful, but DDB entry is not,
(public-access console, or terminal-servers which send spurious breaks)
Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.
- machine independent chip driver, in dev/ic/smc90cx6.c/...reg.h,...var.h,
using bus_space methods
- ZBUS frontend in arch/amiga/dev/if_bah_zbus.c
- added IPL_SOFTNET to arch/amiga/include/intr.h, for this
Implementing the ISA bus frontend is left as an exercise to the reader.
* Improve the midisyn layer a little.
* Add a driver for the Yamaha OPL[23] FM synths.
The opl driver is not finished yet; it sounds pretty awful.
For some strange reason I cannot get any FM sound from my SB64 cards,
but a regular SB16 works fine.
the /dev/rmidiN devices, or with a sequencer interface via /dev/music.
So far the only supported MIDI device is the MPU401 port on SoundBlaster
(and only on SB on isapnp, since we do not have locators with multiple
values yet).
NETHER, NFDDI, NARC are not used anywhere. Remove #include "ether.h",
which had no effect.
Removes clash with "options NATM" for native-ATM network protocol stack.
used in the SMC EtherPower II.
Media control isn't yet supported, due to some MII infrastructure
problems which I hope to address soon. This isn't a huge deal, since
the PHY defaults to auto-negotiate mode.
Also, the device just programs the multicast hash table to accept all
multicast, to avoid a hardware bug that causes the multicast address
filter to lose in 10Mb/s mode. This bug will be fixed in a more sane
way once the media control issues are dealt with.
if_fddisubr.c to fastpath IP forwarding. If ip_forward successfully
forwards a packet, it will create a cache (ipflow) entry. ether_input
and fddi_input will first call ipflow_fastforward with the received
packet and if the packet passes enough tests, it will be forwarded (the
ttl is decremented and the cksum is adjusted incrementally).
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
down "Data modified on freelist" and "muliple free" problems.
The log is activated by the MALLOCLOG option, and the size of the
event ring buffer is controlable via the MALLOGLOGSIZE option (default
is 100000 entries).
From Chris Demetriou, cleaned up a little by me per suggestions in the
e-mail from Chris that contained the code.
now lives in dev/ic, wd now lives in dev/ata. there's now a 'ata'
interface attribute defined in conf/files, but wdc can't go there
yet because some ports still use private versions based on the old
ISA version.
pseudo-device rnd # /dev/random and in-kernel generator
in config files.
o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
and shell script support to be optional (conditioned on EXEC_SCRIPT).
Remove the implicit inclusion of EXEC_ECOFF when COMPAT_OSF1 and/or
COMPAT_ULTRIX is included, and of EXEC_ELF32 when COMPAT_LINUX and/or
COMPAT_SVR4 is included.
Understands allocation aligment and boundary restrictions, "specific region"
allocations, and suballocations. Capable of statically or dynamically
allocating map overhead.
Many thanks to Matthias Drochner for running the code for me, and sending
me bug fixes, optimizations, and suggestions. Also, many thanks to
Chris Demetriou for his extremely helpful suggestions.
XXX No manual page yet. One is forthcoming, as soon as I can scare up
the time to write one. This has been sitting on my plate for quite a
while, and several projects are waiting for it. Time to move on.
bus-independent core driver. Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>
bus support want to attach to should be declared in conf/files, so that
hairy ordering constraints on the inclusions of busses' "files" files
in files.{MACHINE} are avoided. isabus, pcibus attributes will go here later.
The problem is, for instance, that there are some devices in files.isa
currently which require that 'pci' be defined, but there are some PCI
devices (e.g. 'sio' on the Alpha) that provide isabus interfaces, i.e.
'isa' busses attach to them. Unless the the bus-attachment attributes
are here, it's impossible to declare the busses' files and attribute
dependencies in a machine-independent way.
and the "kernel.tar.Z" distribution on louie.udel.edu, which is older than
xntp 3.4y or 3.5a, but contains newer kernel source fragments.
This commit adds support for a new kernel configuration option, NTP.
If NTP is selected, then the system clock should be run at "HZ", which
must be defined at compile time to be one value from:
60, 64, 100, 128, 256, 512, 1024.
Powers of 2 are ideal; 60 and 100 are supported but are marginally less
accurate.
If NTP is not configured, there should be no change in behavior relative
to pre-NTP kernels.
These changes have been tested extensively with xntpd 3.4y on a decstation;
almost identical kernel mods work on an i386. No pulse-per-second (PPS)
line discipline support is included, due to unavailability of hardware
to test it.
With this in-kernel PLL support for NetBSD, both xntp 3.4y and xntp
3.5a user-level code need minor changes. xntp's prototype for
syscall() is correct for FreeBSD, but not for NetBSD.
add 'fddi' attribute, and files descriptions for it.
XXX add 'pdq' attribute, and add files descriptions for it. This is to
XXX support the various front-ends that use his driver (which will eventually
XXX live on PCI, EISA, and TC busses at least). This is probably not the best
XXX way to arrange this, but i can't think of a better way without whacking
XXX a lot of things.
<polk@bsdi.com>. His notes are as follows:
------------------------------------------------------------------------------
July 22, 1993
- Changed name of entire package from PCFS to MSDOSFS
- Fixed bugs:
root directory size in clusters instead of bytes
growing directory didn't update in-core size
link, symlink, mknod didn't free locked parent (deadlock)
lookup returned real error on create and rename instead of EJUSTRETURN
rename changed `.' entry in child instead of name entry in parent
rename removed `.' entry in child instead of removing entry in
parent when moving a directory from one dir to another
createde() left new node locked when write of parent failed (deadlock)
removede() decremented refcount even on error (rmdir's which failed
due to write errors left in-core cache entries inconsistent)
changed validation for filesystem to not check for the boot signature
since some disks (e.g., mtools) aren't bootable
directories are always show current time as modify time
(needed for NFS export since DOS never updates dir mod times --
ctime is true create time).
- Added support for cookies changes to the readdir() vnode
interface (#ifdef __bsdi__)
- Punted on the whole problem of inode generation numbers. This means
that there's a chance of using a stale file handle to access a new
file, but it doesn't appear to be the common case, and I don't see
how to generate reasonable generation numbers without changing something
on the disk (which is the way the SVR4 filesystem survival kit guys
did it). I don't think it would be very safe to change the on-disk
format.
