'command slots' in which the host can put command and wait for the script
to start them
- Change siop.c to do full disconnect/reslelect, allowing as much as one
command per target/lun to run in parallel.
- Fix bug in registers init where a board without BIOS would end at
ID 0 (now the driver works on alpha too).
- better handling of messages, sending back a MSG_EXT_SDTR in response to an
incoming MSG_EXT_SDTR, and MSG_MESSAGE_REJECT for unhandled messages.
- fix use of bus_dmamap_sync() and htole32().
- supports shared interrups
- change some int8 and int16 to int, for alpha and mips benefits ( suggested by
Toru Nishimura)
- Use le32toh() on reading rxstat from the Rx DMA buffer.
- rl_read_eeprom() should return EEPROM values in little endian
when caller requires byte-stream data.
bus_dma(9) fixes are still on-going.
XXX rtk on macppc seems to make tons of CRC errors...
XXX Does it work fine on i386 or others?
(the name 'siop' is still being discussed, may change).
Only basic disconnect/reselect for now, no sync/wide negotiation.
Tested with 810A, 875 and 895 on i386 only.
The bus-independant part should also be able to handle the 53c720 and 53c770.
A new driver with enhanced script should appear for the 825/875/895 'soon'.
to BHA_MBX_OFFSET and using it also for mailbox_in. Since all mailboxes
should be placed in a single continuous memory due to a hardware limitation,
an offset of any mailbox can be/should be calculated using a same expression.
- be persistent on initializing interfaces, even if there's manually-
assigned linklocal, multicast/whatever initialization is necessary.
- do not cache mac addr in the kernel. grab mac addr from existing cards
(this is important when you swap ethernet cards back and forth)
now ppp6 works just fine!
call in6_ifattach() on ATM PVC interface to assign link-local, using
hardware MAC address as seed.
(the change is in sync with kame tree).
cardbus_get_capability() [mirror change already made to if_tlp_pci.c]
- if_tlp_cardbus.c: If we don't find an ISV SROM, try to grab the
Ethernet address from the CIS.
- if_tlp_cardbus.c: set CardBus cards to store-and-forward mode from
the get-go.
- Put the TxThresh tables in tulipvar.h, and use them in the CardBus
and PCI front-ends to go to store-and-forward mode.
- Document the Xircom X3201-3 clone a little more.
delay(1000000) and retry. The 1s delay is needed for some special case only,
no need to hang the machine for that long everytime (especially for PCMCIA).
that Charles added in rev 1.58. Not only is it good programming practice
to explain magic, but code that looks like:
reg = pcic_read(h, PCIC_IDENT);
reg = pcic_read(h, PCIC_IDENT);
is _gonna_ be interpreted as a cut-n-paste error by someone eventually.
if an IRQ was not detected, unless the force flag was given. Use this to
detect if the IRQ was for us (closer to shared IRQ for controllers which
don't have their own IRQ handler in pciide.c) and to poll for DMA xfer.
Also makes the timeout recovery code simpler.
- ATAPI cleanup: don't call controller-specific functions from atapiconf.c
(wdc_*), so that it's possible to attach an atapibus to something else
than a wdc/pciide (Hi Lennart :).
Overload struct scsi_adapter with struct atapi_adapter, defined
as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points
to an scsi_adapter, atapi code casts it to atapi_adapter if needed.
Move atapi_softc to atapiconf.h so that it can be used by the underlying
controller code (e.g. atapi_wdc.c).
Add an atapi-specific callback *atapi_probedev(), which probe a drive
in a controller-specific way, allocate the sc_link and fills in the
ataparams if needed. It then calls atapi_probedev() (from atapiconf.c)
to do the generic initialisations and attach the device.
- While I'm there merge and centralise the state definitions in atavar.h.
It should now be possible to use a common ata/atapi routine to set the
drive's modes (will do later).
Actually, it is partially duplicated with SIOC[GS]IFMEDIA and
SIOC[GS]80211NWID ioctls currently supported. But I'd like to leave it
until configuration interface for common 802.11 stuff will be cleaned up.
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
make them type-generic, which is necessary i.e. to operate on file offsets
without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
integral type (paddr_t, vaddr_t).
Originally done by Chuck Silvers, updated by myself.
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
- Make synchronous writes optional, disabled by default (*way* too slow).
- Handle case where dm_nsegs > CAC_SG_SIZE.
- Fix a couple of silly bugs.
- Fix use of __attribute__((__packed__));
field in the softc, instead of relying on NPCI > 0. This would
prevent things from compiling if PCI buses were in the config file,
but ahc was attached only to something else than the PCI bus.
media.
- read out original settings to find out what the defaults (EEPROM) for this
board were, instad of hardwiring to auto.
XXX the first might need further refinement. At least on my boards, 10baseT
doesn't work for 10baseT, only AUTO.
handling. This is important when multiple cards are present when
the system boots, as we use tsleep now instead of delay in various
places (delay used to provide serialization by virtue of not causing
a context switch).
old data in pointer fields. NOTE: we'll extend m_pkthdr field soon.
Wondering: do mbuf pre-allocation code in elink3.c really buy us much
performance? it comes with code duplicate/synchronization problem with
sys/mbuf.h...
- Cosmetic changes.
- Shut down all HBAs "simultaneously", not individually.
- Don't bother grokking HA_ST_MORE. It causes problems.
- Other bits and pieces.
turning back on fast posting!). Redo fabric (re)login loop- don't try
and log out ports that haven't been logged in. Do correct target id
shuffling so we just always find the target ID we want. Add in support
for > 12 byte commands for parallel SCSI. Handle some Dual Bus reset
stuff. Finally fix ABORT COMMAND to use the right 16 bit order of the
handle to abort.
DRQ is not asserted). Closes kern/9346.
- Change the "fake identify before the real one" by a delay(). The real cause
of the problem is that the drive is unresponsive just after a reset.
The real problem (and the solution) showed up after the first change.
generateion parallel SCSI cards (1240/1080/1280/12160). Split up nvram
reading routines to be more readable. Fix topology reporting- 2200 has
connected topology in mailbox 6 when you're done getting your loop id
(supported: Private Loop (NL Port), N-Port, F-Port, FL-Port). The 2100
doens't report this, but we can synthesize it to be either NL-Port or
FL-Port. Add in some connection mode async events.
