systems with a Frodo Utility Chip. This is essientially an 8250 with
3 bytes of padding between each register. From mike smith

- While servicing an rx, tx, or modem status interrupt: if we have a
NULL struct tty * or if the tty isn't open, just return.
- Skip the self test if we are the console; it manages to do funny
things to autoconfig messages. (XXX - this should be fixed)
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.
- Always ensure that RAW_PART ("c") can be opened.
- Disallow unused or non-existent partitions from being opened.
- Don't do bounds checking or partition translation on RAW_PART.
This is consistent with other disk drivers in the NetBSD source tree,
and fixes a condition where the user could not fix a corrupted disklabel
due to a bogus offset for partition "c".
We're about 75% there. SCSI and HP-IB are not yet supported in a new
config kernel; some autoconfiguration hackery has to be done there, yet.
These changes are enough to network boot a diskless kernel.
New config glue is enabled with the "NEWCONFIG" kernel option. If that
option is not present, an old config kernel will be built. Any kernel
configured with config(8) will automatically pick up the NEWCONFIG
option from std.hp300.
dmacomputeipl(), which is called by drivers which use DMA once they've
hooked up their interrupts. This new function computes the appropriate
ipl to use for the DMA controller and (re-)establishes it's interrupt.
an unrecognized keyboard produced garbage on keypresses in the kernel,
but worked in the boot program (which has this default). The bug is
that the keymap pointers are unitialized.
the keyboard to work. Fixes a bug where booting with `-d' worked
only on systems using a serial console.
While I'm here, eliminate some redundancy in the ite console intialization
code.
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.
Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.
remove their 'integrate' (usually defined to be 'static') keywords.
when lance drivers are split up by attachment, more than one file will
reference the copy/zero functions (i.e. not just the file that pulls in
am7990.c... and eventually inclusion of am7990.c should go away entirely).
outside of "internal i/o" space to not even have a chance at console-hood.
Fix tested by Thorsten Frueauf <frueauf@ira.uka.de>, and offered with
my sincerest apologies that the bug ever existed in the first place.
to a softc, rather than a unit number. Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.
YAY! No more need for dcafastservice!
HIL: squish instances of "(void) splhil()" and "(void) spl0();".
intent for the value of the C_REL constant was 0xc0. Testing has turned
up no adverse effect on tape or disk devices, and in fact this change
apparently makes my 9145 tape work as expected. (!) Closes PRs 1874 and
1971.
to the identification request in rdmatch(). Similar in spirit to a
patch from Jason Downs (written eons ago), but limited to the broken
device we're trying to reach. My patch tested (and fixed :-) by
Herb Peyerl.
- New metrics handling. Metrics are now kept in the new
`struct disk'. Busy time is now stored as a timeval, and
transfer count in bytes.
- Storage for disklabels is now dynamically allocated, so that
the size of the disk structure is not machine-dependent.
- Several new functions for attaching and detaching disks, and
handling metrics calculation.
Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.
For usage and architectural details, see the forthcoming disk(9) manual
page.
squished into an 8-bit position in a command stream! Which one is wrong?
Changed the constant from 0x140 to 0x40, which is what ended up happening
anyhow. This exists in the old Utah sources, too! How long has this
bug existed?!
and LE_RINT_HOOK to blink the "LAN transmit" and "LAN receive" LEDs on
the front panels of 400-series machines iff the CPP symbol USELEDS is
defined in the kernel config file.
This is a step towards getting the drivers ready for new config.
Clean up namespace, remove several instances of global arrays. Instead,
use a softc to carry state around. Where possible, pass a pointer to
the softc rather than a unit number.
Pointers to hardware and software constructs are now stored per port
in each instance of the softc (one softc per board) rather than indexed
by minor number.
