- Simplify and correct the bus manager election process.
- Check link_active when choosing cycle master.
- Fix location of the cmr bit.
Approved by: re (scottl)
- Remove getcsrdata().
- Don't print device type, this can be obtained by fwcontrol.

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
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)
- Clear PCIM_CMD_MWRICEN:
some chips seem to have problem with write invalidate.
clearing this bit fixes SBP timeout problem.
Tested by: Michael Reifenberger <Michael.Reifenberger@Plaut.de>
- Set PCIM_CMD_SERRESPEN and PCIM_CMD_PERRESPEN
- Moderate value for latency timer.
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.
branches:
Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.
This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

This should fix some problem of SBP2 device probing.
Prior to rev 1.41, we keep writing the register while bus reset phase.
But in rev 1.41, we ignore successive bus reset events and some chips seem to
clear the register after we write to it.

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.
- Get rid of the useless atop() / pmap_phys_address() detour. The
device mmap handlers must now give back the physical address
without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
int. Now we properly pass a vm_offset_t * and expect it to be
filled by the mmap handler when the mapping was successful. The
mmap handler must now return 0 when successful, any other value
is considered as an error. Previously, returning -1 was the only
way to fail. This change thus accidentally fixes some devices
which were bogusly returning errno constants which would have been
considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
no longer used.
- Convert all the d_mmap_t consumers to the new API.
I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.
