EIO. The spec says ATAPI devices should support "PIO 3 or better".
They are supposed to support less as well. Setting the device to a highter
mode than the controller shoul'nt be a problem, and this is likely what
happens with legaty ISA controllers.
Solve problem reported by Ruey-Shyang Guo.
Big-endian CPUs should use bus_space_{read,write}_multi_stream methods
to PIO packet data to NIC in 16-bit or 32-bit chunks.
Make it so.
Since we don't have stream methods on all ports yet (esp. i386), use
the bus_space_{read,write}_multi methods if the compile-time
stream-method feature-test macro is not set.
Originally from tsubai@netbsd.org, via HAYAKAWA koichi's cardbus patches.
we can identify them as cardbus chips supported by the cardbus patches.
Add entry for OPTI chipsets whose interrupts arent properly set up by
some BIOSes.

- Don't rely on ATA signature: some ide controllers seems to not transmit it
properly (SIMIDE on arm32 machines). Instead, when we guess a drive is here
after reset, just mark it as ATA and OLD is it's not ATAPI.
- at attach time, use IDENTIFY to eliminate ghost from the probe. If the
drive had the old flag and IDENTIFY failed, issue a WDCC_RECAL command
to detect a pre-ATA disk. If IDENTIFY succeded, remove the OLD flag,
it's obviously not a pre-ATA disk.
- add a new controller flag, WDC_CAPABILITY_PREATA, used to shorcut parts
of the probe (not necessary, but makes the probe/attach faster). This is
only set by the ISA front-end, all other controllers supported can't have
pre-ATA drives attached.
The mechanism used are more or less the same as before, they have just been
reordered. Should solve port-arm32/7324 (waiting for feedback).
- the cap field is a u_int8_t, so none of the defined flags would fit in.
Looks like nobody had a drive using 16 bytes commands.
- the ACAP_DRQ_* flags are all wrong. Just remove them and use the definitions
from ata/atareg.h, there's no need to duplicate theses. The effect of this
was that we were always polling for the command phase, even for drives
with interrupt DRQ. This didn't break until the code was changed to support
shared interrupts.
Should fix the lookup problems or 'boot hangs' reported by some users, and
kern/7111.
clean bit. This is somewhat bogus as RAID 0 does not have any parity,
but is a slightly cleaner than other solutions, and makes the handling
of clean bits for RAID 0 consistent with the handling of clean bits at
other RAID levels.
board versions with no BIOS. Separate mailbox interrupts from
IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not
after you clear it (potential race condition). Clear out older broken
BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup
if already in LVD mode. Note usage of presumptive 1040C revision. For
all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state
as unknown as well as marking the need to do a getpdb on targets- after
a LIP for certain the f/w has to do PRLI/PLOGI for all targets again
and marking f/w state as unknown gives us a fighting chance to (start
to) hold up for that to complete.
that will SBusify an isp header or the lun/target portions of a request IOCB-
and have these only valid iff __sparc__ (no non-sparc SBus machine that *I*
know about).
