in epsetmedia() if full-duplex is selected (new feature on these cards!)
On MII Boomerangs, set the full-duplex bit in MAC CONTROL in the statchg
callback from the MII layer. Should fix full-duplex on these cards.
* 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.
No DMA is wired up, it has a shared memory interface, and a FIFO buffer
which can be used to speed up PIO transfers. (The latter two are
PCMCIA-specific speed hacks to deal hide the performance lossage from
using a PCMCIA->PCI bridge internally.)
the 3Com 3c905-TX and 3c905-T4. Fix handling of the MII on the
3c595-MII and 3c597-MII (can't talk to the PHYs on these cards; just
use "manual" for the external MII port).
Fixes kern/4782 (Chris Demetriou).
The attach routine calls zsparam if we're setting up the console, and
zsparam needs this field to tell which zstty to set up. Otherwise, we
set up zstty0 even if it's not the console!
a "fast scroll" by setting the display start in memory.
(Only implemented for "scroll up" because this is more used. "scroll down"
is easy to add.)
This moves the semantics of "copyrows" to something like "moverows";
the contents of the new visible lines at the bottom is undefined.
The emulations can live without the original "copy" semantics.
clock source. Now, when my EtherPower II locks up, it eventually recovers!
(Geez, I'd like to know why it does this, and only apparently in 10mb/s mode).
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.
On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).
us to call isp_reset/isp_init internally with impunity.
Rename isp_phoenix to isp_restart and make it global. Clean it up a tad.
If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and
return- the f/w is toasted at this point (usually), so we have to bring
things back to a known state.
In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and
find out if the isp is trying to tell us something and try again. This
may avoid a potential deadlock where the previous mailbox command hasn't
been cleared by the ISP.
In isp_init don't try and get device parameters if we already have them-
this typically doesn't work if we're in the middle of an isp_restart.
There is one change of note- build a list of completing commands in
ispintr and then say you're done- this avoids some re-entrancy issues
that had surfaced.
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
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.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
it implemented under the label `shortcut:' and only use it in these
cases: (1) after successful re-relection, (2) after receiving command-complete
status, and (3) during message-in handshake.
for front-ends to override the allocation to avoid alignment
handling in their DMA engines. Note that that ncr53c9x_msgout()
can request a 1 byte DMA transfer that would be difficult to break up.
Cute buglet: you can end up with zero CCBs if there were no targets
seen by the adapter. Always leave a minimum so the adapter can
finish attaching- it may be there w/o targets for a reason.
the capacity based on the c/h/s numbers. In fact, don't use the c/h/s
numbers for much of anything.
For ATA-4 drives or later, always use LBA mode, since it's now required.
Collectively, this allows >8GB disks (like the 12GB Bigfoot) to work.
Compute the disk block addr at command queing time rather than exec time.
This fix a bug which could lead to data corruption on disk: when a command
was reexecuted after an error condition (from wdcunwedge), the partition
offset was re-added to the block addr, leading to a transfert at the wrong
disk block.
This should fix the problem reported by some laptop's users, where the
first disk read after a suspend/resume returned garbage.
to compile. I made the changes that seemed to make sense tracking the
shift from TS_WOPEN to tp->t_wopen- but they may be wrong. I wasn't
subscribed to tech-kern so I missed the discussion, and C. Hannum
was not particularly enlightening. Sorry if this isn't quite right.
two SCC channels, and can get stuck in an infinite loop. This change
stops after flushing 4 bytes. Might need upping to 8 bytes if we support
85230 ESCC's.
Idea bounced off of scottr & gwr
- In the console getc routine, block until a character becomes ready
(no, really, we mean it). This routine should _never_ time out.
- In the console putc routine, if the UART has trouble, do NOT proceed
to print a diagnostic message, which would recursively invoke the
console putc routine ad nauseum.
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. :-)
the "stream" busification functions.
In the architecture as the BeBox(CPU is big endian, have ISA bus),
These methods would be used where "raw" data needs to {read,write,set}
unchanged.
Add #ifndef __BUS_SPACE_NEED_STREAM_METHODS (define that on NetBSD/bebox),
if not define __BUS_SPACE_NEED_STREAM_METHODS,
define "stream" busification functions to normal busification functions.
This is useful in the case where an attachment's probe routine
verifies that there is indeed hardware present but something goes
"wrong" in the attach causing the device to be unusable. (Without
keeping track of this, in that case incorrect ports could be
accessed or uninitted pointers could be deferenced on open or at
other times.)
an initiator/target nexus and thus mark the correct queue (if any) a
command is on.
* If a disconnected command times out, just leave it on the nexus queue
and do nothing (for now). I need yet to decide on the strategy to
follow in this case. Note: we used to move the command to the `ready'
queue and then do nothing, which is worse.
the target still is in MSG OUT phase. We still send a message (a NO_OP)
in this case and the chip will remove ATN at the appropriate time.
Using the RSTATN command here induces a "illegal command" in some
chip revisions.
This situation only occurs if the target rejects a previous (multi-byte)
message early (by switching to MESSAGE IN and sending a MESSAGE REJECT)
before the chip has completed the entire MSG OUT transfer. ATN will
remain asserted, and the target returns to MESSAGE OUT phase.
* Account for the events above when reporting "DMA not completed"
diagnostic messages.
* Stream-line the selection code a bit, and make the DMA setup code
more like the MSG OUT & DATA XFER setup.
* Fix bug in wdc that would overflow ATAPI transfer length.
* Improve wdc probe code so that 'wdc' is probed in if present
even if there are no drives attached, and so that it works
properly even if the only device is an ATAPI slave.
* bus_space-ify.
* split the ISA attachment from the wdc driver, and remove
ISA dependencies from non-ISA files.
* claim that wd and wdc are now machine-independent (probably not
completely true, but mostly so; they at least work on arm32 and
i386).
* Various other minor fixups and cleanups, some of which were pointed
out by Kazuki Sakamoto.
- "out of resource" errors cause receive buffer chain corruption
- resets can confuse the interrupt handler
- multi-cast setup causes receive buffer chain corruption
- shared memory setup incomplete
* Enhance effiency by avoiding unnecessary shared memory access,
improved handling of receive frame & buffer descriptors, and
introducing an `asynchronous' option when issuing 82586 commands.
* Exclusively use offsets relative to the bus handle representing the shared
memory area to formulate accesses to the chip's data-structures. The
front-ends provide glue functions that cater to the chip's endian-
sensitivity, to perform the actual device access (note: single-byte
accesses are done here using `bus_space_{read,write}_1()').
This concludes the transformation into a bus-independent driver module.
* Abolish C structures to access chip data-structures; instead use macros
that take indices and offsets relative to the bus handle representing
the chip's resources.
* Include the old version of this file wholesale, until all drivers
have been updated to use the MI 82586 code.
- allow get/set of enums SUNAUDIO_SOURCE and SUNAUDIO_OUTPUT rather
than returning EINVAL
- add missing SUNAUDIO_MONITOR_CLASS case in query_devinfo
- convert SUNAUDIO_MONITOR case from a MIXER_CLASS to a MIXER_VALUE
like it is supposed to be
- the labels for outputs/record class were swapped: fix it
this patch allows "mixerctl" to work properly on a sparc
- clean up debug code
- Don't check ATAPI signature when probing ATA drives, ATAPI devices were
detected before
- Reset controller after disks probes. The probe, with some combinations of
ATA/ATAPI device keep it in a mostly working, but strange state (with busy
led on)
- The WDCF_IRQ_WAIT flag is now cleared by wdc_ata_intr and wdc_atapi_intr
when appropriate (helps recover from failure conditions)
- In wdcunwedge, send ATAPI_SOFT_RESET to non-ata drives
(helps recover from failure conditions)
- in wdctimeout be a bit more verbose when we missed an interrupt
- Always Increment xfer->c_skip where it should be
- Set the ITSDONE flag when a polled command completed.
more robust in resource shortage situations, basically identical to
code I added to the "ahc" driver some time ago.
Thanks to Brad Spencer for the testing help.
* Make the ring buffer size and water marks patchable, and allocate the buffer
separately.
* Do the ttymalloc() at attach time.
* Reorganize the receive buffer so the status and data pair are next to each
other. This is slightly faster.
* Make sure we actually do turn off interrupts in comclose() if we have DDB
configured and it's not the console. (D'oh!!!!)
* When we exhaust the current transmit run, turn off transmit interrupts in
comintr(), so we're fairly sure we don't get another one.
* Nuke the silly lsrmap[] idea; it's slower in the normal case.
* Cache the l_rint pointer in the soft interrupt routine.
* Carrier detect (TS_CARR_ON) is based on the actual DCD bit, even if it's
being ignored.
* Set TS_WOPEN early on in zsopen().
* Don't disable interrupts on the console during close if we have DDB.
Inert changes:
* Don't handle ZS_HWFLAG_NO_DCD here; the frontend does it.
* Deprecate `register'.
* Use SET(), CLR(), and ISSET().
More performance changes:
* Rototill receive handling; use a backpressure mechanism to prevent livelock.
* Output silo/ibuf overflow warnings at most once per minute, from a callout.
* When we exhaust the current transmit run, turn off transmit interrupts in
zstty_txint(), so we're fairly sure we don't get another one.
* Make the ring buffer size and water marks patchable, and allocate the buffer
separately.
* Do the ttymalloc() at attach time.
