- In dpt_intr(), if no interrupt is signalled but the HBA has indicated
that more data will be available soon (HA_ST_MORE), save a context switch
and wait for the data.
to the SCSIPI subsystem.
- Determine more characteristics about the board, including the number
of concurrent commands that the processor can execute at a time.
- Rework memory allocation strategy so that we can do dynamic pre-allocation
of resources according to workload.
Thanks to the Linux Buslogic driver for having some useful comments.
until Matt Jacob has a change to update the driver for the latest
firmware, etc. since update device parameters seems to fail once the
system is really up and running, and eventually causes the controller
to wedge. This may be due to a firmware bug.
Per discussion with Matt.
- `flags' is now gone, replaced with `xs_control' and `xs_status'.
- Massive cleanup of the control flags. Now we explicitly say that
a job is to complete asynchronously, rather than relying on side-effects,
and use a new flag to now that device discovery is being performed.
- Do SCSI device discovery interrupt-driven.
- 82C115 has a 128-bit multicast hash table, not 512-bit.
- Correct the way the MAC address is read from the SROM, after re-reading
the MX98715A Application Note.
Other semi-related changes:
- Differentiate between MX98715 and MX98715A.
- Improve the Macronix link-up/link-down detection.
this by frobbing the 10TCTL register minimally, toggling only the bit we
care about (and hoping that link-capability advertisement happens correctly).
MX98715 can talk to the network now.
- Add a comment about the Macronix MX98713 -- it's almost exactly like
a 21140A, and doens't have the Nway registers that the other Macronix
chips have.
- Bus specific front-end is now responsible for reading EATA configuration
- EATA configuration data is now saved in the softc
- Make synchronous writes work properly
- Don't ignore HBA timeouts in dpt_cmd()
- Prefix eata_cfg's members with `ec_', not `dc_'
* f_lock is only needed for FreeBSD (for their totally disgusting
and insane way of doing generic vnode locking)
* g/c f_mp, it was write-only
* some comments added
