wiz 1ffa7b76c4 DMA, not dma nor Dma. 2003-05-03 18:10:37 +00:00
bouyer b99551540c in siop_reset(), reset sc_ntargets to 0. The number of targets will be
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.

thorpej 4daab7072a Don't access a scsipi channel's periph table directly; use
scsipi_lookup_periph().

bouyer 4b307fe0af It's not safe to access the SCNTL1 register while the SCRIPT is running.
On the 1010 this can wedge the chip. So abort the script instead.
the abort interrupt will trigger a bus reset.

bouyer c7454ad973 - factor out parts of (e)siop_attach() to siop_common_attach()
- Add support for DT transfers (aka Ultra/160) in esiop

Note that DT transfers are not enabled for 53c1010-33 rev 0 yet; if I trust
FreeBSD it has a bug which prevent them to do DT properly.
From the same source there may be issues with some revs of 53c1010-66.

bouyer 6d37782a49 Bump the space for SCSI messages from 8 to 16 octets, as 8 may not be
enouth for IDENTIFY + TAG + PPR.
Get rid of constants in C code by use of a offsetof macro.

bouyer cf06149dac Enable software LED control based on LED0 feature, not #define.
For now, set the LED0 feature if SIOP_SYMLED is defined in siop_pci_common.c.
From Jason R Thorpe.

bouyer e3f96dde51 Fix last change: assign siop_cmd->tag in callers instead of siop_setuptables(),
and use siop_cmd->tag instead of xs->xs_tag_id. This way siop can use
xs->xs_tag_id + 1 without interferences with esiop.
2002-04-22 15:48:55 +00:00
bouyer 72906f4578 In siop_setuptables(), use the proposed tag_id, not tag_id +1.
In siop.c bump siop_cmd->tag by one as tag id 0 is reserved for untagged cmds.
2002-04-22 09:43:44 +00:00
bouyer 97fe8b91c5 Move a few things around, so that ic/siop_common.c and pci/siop_pci_common.c
can be compiled without including siopvar.h.

to convert xs->timeout to callout() parameter.

bouyer ea29ee7d56 Call siop_morecbd() only when scsipi ask us ADAPTER_REQ_GROW_RESOURCES.
This prevent using bus_dmamem_map() from interrupt context.
Should fix kern/13827.

bouyer 937a7a3ed9 Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

bouyer 0653304779 Avoid sending new commands to the device if it has sense pending:
- run request sense command without disconnect
- don't restart the script before siop_scsicmd_end has been called if the
  cmd didn't complete with good status.
- reserve slot 0 for request sense, to make sure it'll be sent first.

bouyer fc92601259 Fixes related to QUEUE FULL status:
- move status handling in siop_scsicmd_end(), it's better than in siop_intr()
- define 2 internal SIOP status, for "no status reported by device" and
  reset condition
- add a list of "urgent" command, to be executed before the list of command
  queued the normal way; this is used for command which got aborted
  by a QUEUE FULL and have to be requeued in order.
- Don't accept to send a Q_TAG message not immediatly folowing a IDENTIFY

bouyer 10afc4e0a8 create a funcion, siop_busreset(), to reset the scsibus.
Reset the scsi bus at attach time, to be sure all devices start in narrow/async
mode.
Defer sync/wide negotiation until after whe have a valid
xs->sc_link->device_softc, so that we can honnor the NOSYNC/NOWIDE quirks.
