Many internal structure changes for the FireWire driver.
- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current. Mark the interrupt routine as MPSAFE.
- AR buffer handling.
Don't reallocate AR buffer but just recycle it.
Don't malloc and copy per packet in fwohci_arcv().
Pass packet to fw_rcv() using iovec.
Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode. We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
not cycle master capable but set myself for root node.
We should be the root node after next bus reset.

- Improve self id handling
Tested on: i386, sparc64 and i386 with forced bounce buffer
in geom_disk.c.
As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.
Improve SBP device probeing:
- Wait 2 sec before issuing LOGIN ORB expecting the reconnection
hold timer expires.
- Serialize management ORB and scanning LUN by CAM on each target.
This should fix the problem for devices which have multiple LUNs.
Test device is donated by: Jaye Mathisen <mrcpu@internetcds.com>
- Freeze SIM queue for 2 sec after BUS RESET.
- Retry with LOGIN rather than RECONNECT after LOGIN is not completed for
BUS RESET.
- Use appropriate CAM status for BUS RESET and DEVICE RESET.
- Let CAM to scan targets after BUS REST.
- Implement CAM scan target function.
- Keep our own devq freeze count.
- Let CAM to know that SBP does tagged queuing.
These should be merged to RELENG_4 before 4.8-RELEASE.
Some drives seem to be confused by simultaneous probes.
Tested by: marcel
As a side effect, logical units whose lun is greater than 0 might not be
probed correctly if the lun of 0 doesn't exist in the target because
CAM doesn't scan such luns.
I have a SCSI-FireWire bridge which maps SCSI-ID to LUN and it is an
example of such targets.
- Don't initiate bus reset even if probe failed for some nodes to prevent
infinite bus reset loop.
Problem Reported by: Pierre Beyssac <pb@fasterix.frmug.org>
- Protect timeout routine with splfw() for 4-stable.
* sbp.c
- Make sure to release devq when start request.
previous revision fixed the panic, I found the problem exits in
another part of the function by investigating the crom dump sent by him.
The search was started in the middle of bus info block and the
routine misunderstood the EUI64 as a crom entry. This problem is fixed.
PR: kern/48129
Fix incorrect type mask included in a logical unit number and check
the validity of the lun.
- Drain fwohci TX queue first then drain xfer queue which has not started.
- Check validity of the received packet length.
- Don't allocate too large buffer for xfer receive buf.
sbp
- Fix panic for some CROM which doesn't have a text leaf.
This could fix the PR kern/48129 but no feedback has been gotten from
the originator yet.
- Put back some M_NOWAIT flags into malloc which could be called
in interrupt context for 4-stable.
- Fix overwrite problem of freed buffers. It was rare but could happen
when fwohci_arcv() is called before fwohci_txd() is called for
the transcation.
- Drain AT queues and pend AR queues on SID receive rather than BUS reset to
make sure DMA actually stops.
- Do agent reset in sbp_timeout().
- Restore pci config registers after resume.
- Reinitialize and start rx buffers after resume.
- Don't reallocate memory in fwohci_db_init() if the dbch is
already initialized.
- Fix typo.
- Some clean up.
- Fix permission of device node.
fwochi.c, fwohcireg.h
- Detect phy access failure correct way.
- Set root hold-off bit before initiating bus reset.
This should fix the problem with VIA6306.
fwohcivar.h
- Fix over-allocation of array. (fwohcivar.h)
sbp.c
- Return CAM_DEV_NOT_THERE rather than CAM_TID_INVALID to prevent retry.
