intr_alloc_mask) into one place, comment them, and defopt them.
- Rename pcic_intr_alloc_mask to pcic_isa_intr_alloc_mask, since it's
an ISA-specific thing.
- When allocating/establishing the PCIC's interrupt (for card events),
do error checking, and pay attention to the intr_alloc_mask.
for the built-in SCSI on NEC Versa docking stations, and if a card
allocates that IRQ, it will never get interrupts. This caused the
default kernel to not work on these laptops, as IRQ 10 was often the
first free IRQ.
things happen if we are the console.
Restore to the prevoius value (not to hardwired 8N1) because this
could be set by the serial console initialization.
Closed PR kern/4373 (Dave Huang)
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.
should creation/initialization of a ccb fail. Also, don't panic in
these situations. Instead, simply return an error condition and allow
the caller to deal with it. It may be the case that we were able to
create one ccb what we can grab, and continue to hobble along.
Also, fix the scb freelist fencepost, like the aha/bha/uha drivers.

these situations. Instead, simply return an error condition and allow

Also, fix the mscp freelist fencepost error, similar to aha.c and bha.c

- add a type field to the isapnp_pin struct and set to IST_EDGE or
IST_LEVEL depending on the card configuration data.
- use the irq type field in all the drivers instead of hardcoding it.
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.

change KEYSYM_HOLE to KEYSYM_NOP most places in those tables.
Map the `R' function keys with KEYSYM_FUNC_R instead of the
arrow key strings so that numlock indirection works.
- 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".
* Make sure all uses of the data pointer are type-cast appropriately.
* Eliminate the super-user check in the KIOCSKEY case (back as it was).
* Return ENOTTY if the ioctl command code is unrecognized.
Instead, print a diagnostic and return. (Some drivers do this already.)
Also, normalize the diagnostic message, and fix some places where the
printfs were getting ugly.
- Work around a bug in the 82557 that causes the receiver to lock up
in certain conditions by kicking the multicast address filter if we
haven't heard anything come down the wire for some period of time.
- Fix a bug that could cause TxCB descriptor chains to cross page boundaries
on the Alpha.
- Remove some unneeded register masking.
- Fix a bug where too much data was copied from the config template, causing
memory corruption.
- Fix handing of if_timer (it was be cleared too early in some cases).
- Attempt to reduce the chances of receiver overrun by doubling the
number of receive DMA segments, and processing receive interrupts
before transmit interrupts.
- Remove a gratuitous assignment.
- Fix a bug where incoming packets were counted twice.
Dave Huang <khym@bga.com>, with added check for broken early versions
of the 16650, taken from the Linux driver.
This should be extended to use, for example, higher trigger levels for
the bigger 16650 FIFO, and its capability for using a smaller divisor
and thus higher speeds. But this patch is very useful for 16650 users
already.
