fvdl ffb3eaa5ea Add extra delay after wdcreset() call in wdcprobe. Needed by at least
one controller, where registers otherwise will still be inaccesible
(even though the busy bit has been reset), making the probe fail.

chuck d76941843e fix mixer code that was clearly untested:
- 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

bouyer f7c6e141e6 Various bug fixes for atapi part:
- 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.

thorpej 03a0c2d900 Implement a simple queueing mechanism that makes these drivers much

code I added to the "ahc" driver some time ago.

mycroft ce29cdf2e7 Set the ring size back to 2k. 1997-11-03 06:56:28 +00:00
mycroft 9b9cce6084 Mostly cosmetic and performance changes:
* 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.

mycroft 7d7ecb9200 Bug fixes:
* 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.

|HUPCL, as in com driver.
Do *not* fiddle with DTR when changing the line speed.
Make sure we update the tty's carrier status when CLOCAL or MDMBUF is changed.

thorpej 7964d4bd34 When probing for a dp8390 in ne2000_detect(), check for RST being set
in the ISR (from the ISA "ed" driver's generic 8390 probe routine).
Also, add a big comment describing exactly what we're checking when
probing for the dp8390 (also lifted from the ISA "ed" driver).

The RST check should help weed-out non-matches before they get to the
fairly invasive memory check.

thorpej d1bfbc66c6 Syncronize with changes to aha.c:
Adjust the number of ccbs allocated during initialization.
Every ccb could potentially lock 64k of memory for dma buffers if bounce
buffers are used.  Instead of BHA_CCB_MAX ccbs using 2MByte, only
sc_link.openings ccbs per device are allocated.  Thus we now use only
256KByte per device present.
(hannken)

Fix a couple of errors in bha_create_ccbs():
- Don't ever let the number of CCBs be creater than BHA_CCB_MAX.
- Fix a fencepost that caused the last CCB allocated to never be put
  on the freelist.

bouyer 917389821c Changes to the probe and attach routine:
- at end of attach, explicitely select an existing drive. This fixes hangs
  some users reported (such as the one reported in port-i386/4247).
- Some atapi cdrom drives (e.g. Nec 24x) don't enables their registers before
  a controller reset is issued. The controller probe routine is changed as
  follow: issue a controller reset. If fail, test atapi signature on slave.
  If fail, wait 5s and retry a reset. If the second reset fail, return(0).
  If the first reset succeed, test presence of a master drive:
  atapi signature, and if this fail RO/RW registers test. If no master, test
  atapi signature on slave. If no slave, return 0.

"A sequence step of 0 after a select with ATN can be a selection
 timeout, or it can also indicate the target did not respond with
 a message out phase.  The latter will occur on very old SCSI
 devices which do not respond to the ATN signal and go directly to
 the command phase".

and thus higher speeds. But this patch is very useful for 16650 users
already.
