mycroft 09cad93ce8 Implement a better backpressure mechanism so that data is collected 
in the driver's buffer if the tty buffer is full.  If the driver's buffer
becomes full, turn off receive interrupts until it drains a bit.

thorpej da1b5f9021 It's perfectly normal for an older (e.g. pre SCSI-2) device to send 
MESSAGE_REJECT in response to SDTR or WDTR.  Because of this, the
printfs that indicate refusal of sync/wide negotiation are unneeded
in normal operation.  In the __NetBSD__ case, disable them by default.
They, like the other extra-verbose ahc driver boot messages, may be
reenabled with "options DEBUG".  The behavior in the !__NetBSD__ case
is unchanged.

thorpej b937ee4745 - Simplify mailbox DMA setup, allowing the front-ends to allocate the 
mailbox storage in a way they see fit.
- Define macros to index and size the request and result queue entries.

mjacob 62b3daa7d2 Finally found the cause of that nagging 'lost command' (for the first 
command) bug: the initial response queue index is take from mbox 5,
not mbox 4, and mbox 5 wasn't getting initialized to zero.

where the driver would sometimes retransmit bytes.

jonathan fac2cd30a0 Set TX-available threshhold in epinit() just before enabling interrupts, 
so TX_AVAIL intrs are enabled for root-on-NFS kernels.
Tested (and required) on 3c595TX with root-on-NFS kernel booted from floppy.

augustss e63a553175 Change the interface between high and lowlevel audio drivers again: 
Set the encoding parameters slightly differently.
Remove the SW encoding/decodinf functions from this interface
and move them to the audio_parameter struct; this is both more efficient
and flexible.

augustss c4a52794f1 Convert to new orthogonal audio encoding scheme and implement 
some of the new encodings.  The change to ioctl AUDIO_GETENC is
NOT backwards compatible.

scottr cd3abdf098 Fix typo in last change. 1997-04-30 19:16:23 +00:00
scottr c0d7fd03ae Remove the use16bit softc field, replacing the functionality with dcr_reg. 
This allows the front end to override the default DCR (byte-wide DMA,
x86 byte order, 8-byte FIFO) with different transfer size, byte order, DMA
parameters, and FIFO threshhold.  If the loopback select bit is not set for
normal operation, the default is used instead.

Inspired by thoughts from Bernd Ernesti.

augustss 526ef2f618 Change the interface between the high and low level audio drivers 
so that all audio encoding parameters are set at once.  This simplifies
the interface and make error checking easier.

mjacob ac6fbba3ac On alpha size_t is not an int, ergo last argument to dma setup glue 
function can't be a pointer to an int.

pk 94eaf1bb04 Implement target selection using DMA. 
To allow a period of testing the variable `ncr53c9x_dmaselect' is used to
enable this feature (default is 0, i.e. the old behaviour).

jonathan dbf4f7b71f * Tidy PHY [sic] selection code in epsetmedia(). 
* epinit() had both explicit xcvr selection for 3c589 and a call
  to epsetmedia().  The first is redundant; delete it, and EP_COAX_DEFAULT.

* Update comments to reflect 3c589 and 3c509B fixes.  Fix typos.

veego bf37fc50d0 Rename the PROD_ID to PROD_ID_3C509 to make it possible to add other 
product id's, e.g. for the 3c515.
 1997-04-27 09:42:34 +00:00
veego a2e1f15ba7 - Replace the check for EP_BUS_PCMCIA in epsetmedia with a check for 
EP_CHIPSET_3C509 and change it a bit so it works now with the 3c509
  and still works with the 3c589.

mycroft 581399fc4c If we fail to allocate a cluster to hold a large packet, simply 
drop it rather than using a chain of tiny mbufs.

cgd dcd9b58489 don't bother keeping around the i/o tag. It's useless by itself, and 
without other significant changes to this driver wouldn't be particularly
useful to keep around permanently anyway.

we check for "wide controller" now.

cgd db0f072019 clean these up (mostly rename bus_space_{tag,handle}_t variables) so that 
this code makes equal sense for memory and I/O space, prefer to map
the PCI front end via memory space (conditionalized on a patchable kernel
variable), and do a bit of other random NetBSD-specific cleanup.  (These
changes were sent to Justin Gibbs on March 28.)

mjacob 6d4d1f8852 Okay, Charles convinced me that XS_DRIVER_STUFFUP is better than XS_SELTIMEOUT. 1997-04-05 22:36:56 +00:00
mjacob ddc693c299 A) Attempt to get clock rate from ISP chip prior to bashing it over the head 
in reset. If none there, try and get from the bus/platform specific code.
If a nonzero value for either, set the clock rate. This is why the PCI
card versions weren't working- they need to be set at 60MHZ, rather than
the default 40MHZ (which worked fine for the internal ISP chips on the
Alpha 8X00).

B) If a isp_poll returns failure (command never completed) to the caller
and no error is set in the xs struct, set XS_SELTIMEOUT. And then call...

C) Added isp_lostcmd function to try and ask the ISP chip about it's current
state as well as the state of commands for a particular target/lun. This is
going along to try and figure out why the very first command to the ISP always
seems to get swallowed up.

pk c59dd873f4 Remove alignment requirement of ether_cmp(): turn it into a series of 
byte comparisons. Compare the ethernet addresses backwards on the
assumption that address number byte 6 has the most random distribution,
so packets not for us spend the least time in here.
