Such RAID controllers are actually just IDE controllers with a BIOS that
can create RAID volumes and write the configuration info to config blocks
on the disks. The BIOS can do I/O to these volumes, and the OS must
understand the config blocks and implement RAID in software in order to be
able to use these volumes.
Only SPAN (simple concatenation) and RAID0 are supported at this time,
and writing back config blocks is also not supported at this time. Currently,
only the Promise configuration scheme is supported, although supporting
the Highpoint scheme should not be too difficult.
In any case, this is sufficient to use the Promise RAID0 volume (thus
preserving the win2k AS installation) on this new Intel server I have.
Thanks to Soren Schmidt for doing the work in FreeBSD; it made this
task much easier. The config block parsing code is adapted from his
work.
a series of Y2k-compliant multiplexed-bus RTC chips. At the lowest levels,
the DS1687 and successors are register-compatible with the MC146818(A) and
DS1287, but also provide Y2k-safe date storage and other extra bits, like a
silicon serial number and larger amounts of NVRAM.
which is safer than the loop there used to be here.
wi_mwrite_bap: if wi_write_bap fails, don't keep on going: this
way you avoid writing garbage to the radio. First time you see
an odd-length mbuf, copy the remainder of the chain to sc_txbuf
and from there to the MAC. This way, you do not read an mbuf past
the end of its data (occasionally you will cross a page doing
that!) and you avoid expensive, excess seeks in the radio's own
buffer chain.
wi_rx_intr: clamp the frame length told to us by the driver to the
most bytes we can fit in our mbuf cluster.
I am still getting e-mails from my testers telling me how much
better this makes things.
LINK_STAT notification for every change of BSSID, so the firmware's
BSSID and the driver's BSSID will get out of sync. This has two
bad affects. First, because the 802.11 framework filters received
packets based on BSSID, many packets can be dropped before the
driver adopts the firmware's BSSID. Second, ifconfig's tells a
misleading BSSID to the operator.
This problem is most apparent in networks where every station does
not hear every other. I reproduce these conditions in an office by
removing/replacing the antennas on my 802.11 cards.
As a solution, in IBSS mode, the driver will ask the firmware for
the BSSID every five seconds. Also, whenever the driver receives
a frame carrying a different BSSID than the driver's BSSID, then
the driver asks the firmware for the BSSID before handing the frame
to ieee80211_input.
the MIF Configuration Register PHY_Select, there is no use in pretending
we could talk to both at the MII interface layer.
If both PHY are reported to be present, prefer the external one.
Remember this selection and enforce it in hme_mii_{read,write}reg.
This fixes problems with one of the dual hmes in Netra T1s.

least 1us. Documentation I've found for the simple (SPP) parallel port
mode says that data should be stable 500ns before STROBE, STROBE should
be pulsed for no less than 500ns, and that data should be stable another
500ns after STROBE has been de-asserted.
Makes lpt@ebus on my Sun Ultra5 work with my HP DeskJet 712C, at least in
polled mode. Thanks to Martin for astutely noting it was probably a bug
with STROBE being pulsed too quickly.
The definitions were not the same between the scsi_messages file and this
definition so simply removing it here and letting the other one be used
results in incorrect behavior (regardless of whether it made the code
compile....)
- Add support for byte system bus mode. Based on patch in kern/17193 by
Christian Groessler, with some improvements by me.
- Rename sc_flags in mb86960_softc to sc_stat, rename "type" to sc_flags
to specify controller quirks and remove enum mb86960_type.
- Pass controller type via new sc_flags in mb86960_softc rather than
via an mb86960_attach() arg.
- Handle unaligned mbufs properly in mb86960_write_mbufs(). (from ne2000.c)
- Fix a signed/unsigned comparision warning.
- Add definitions of status bits in the RX packed header.
- Change types of some members in mb86960_softc.
WI_RID_DBM_ADJUST: In preparation for capturing Prism packets
containing received signal strength indications (RSSI), read the
constant for conversion from RSSI to dBm (decibels relative to
a milliwatt).
WI_RID_FRAG_THRESH: Get/set the packet fragmentation threshold
on Lucent/Prism.
- Move lm_readreg/lm_writereg into the front-ends. Add/use function pointers
in the softc.
- Add a bank select function pointer to the softc and provide a generic
version. WinBond chips accessed over serial bus present three addresses,
two of which are used to access bank 1/2 registers.
- Mark TSENS2/3 sensor data as invalid if the the corresponding bank select
fails.
- Handle IFF_ALLMULTI case correctly. This is necessary to mrouted working.
Tested by taca@netbsd.org.
- Clear unnecessary multicast hash bit. Otherwise, unnecessary multicast
packet is received. Tested by me with the 3C905C bought at akihabara.
It was 2980yen.
The code is written by fvdl@netbsd.org and me.
computed again in siop_add_reselsw()
in siop_reset(), reset the tag reseloff to 0, in addition to the lun reseloff.
If siop_add_dev() fails this time we would use the old reseloff, clobbering
memory now used for something else.
