sym_hipd.c 1.70
- Const'ify firmware and lookup-tables.
- Obsolete redundant inst_name and unit members of struct sym_hcb.
- Fix three more NULL vs. 0 confusions.
- Use device_set_softc(9) to tell the bus layer that this driver
allocates a instance of struct sym_hcb itself.

- Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9)
in order to get rid of bus space handle and tag in struct sym_hcb.
- Remove unused members related to bus addresses in struct sym_hcb.
- sym(4) takes care of allocating an instance of struct sym_hcb
itself so don't let newbus allocate it as an unused softc also.
- Add basic MPSAFE locking. This includes changing the sym(4) CCBs
to be allocated up-front instead of on demand as needed. Besides
making these allocations more likely to succeed, this also solves
the problem of calling bus_dmamap_create(9) with the SIM mutex
held.

- Use NULL instead of 0 for pointers.
- Remove superfluous returns in functions returning void.
- In sym_alloc_lcb_tags() return directly instead of jumping
to a label which just returns.
- Fix some spelling in comments.
- Remove trailing whitespace.
Fix Symbios driver on amd64: Since amd64 has 64 bit pointers but the same2007-07-20T23:02:01ZStefan Eßerse@FreeBSD.org2007-07-20T23:02:01Zurn:sha1:d2a748e2325400163c6142a89941fca8a9c37e04
4KB pages as i386, data structures that just fit in one page on i386 (and
on 64 bit architectures with 8KB pages) can be distributed over two pages
on amd64. This is a porblem in the case of the Symbios driver, since the
SCRIPTS engine in the SCSI chip operates on physical addresses and needs
physically contiguous memory. Earlier patches used contigmalloc on amd64,
but this version replaces part of a structure by a pointer to that data.
In order to not introduce an extra indirection for other architectures,
the change has been made conditional on __amd64__.
Earlier attempts to repair this problem are removed (i.e. the macros that
made amd64 use contigmalloc). The fix was submitted by Jan Mikkelsen and
modified by me to only affect amd64.

Prepare for future integration between CAM and newbus. xpt_bus_register2007-06-17T05:55:54ZScott Longscottl@FreeBSD.org2007-06-17T05:55:54Zurn:sha1:b50569b71dfb110a58aa3e83f629115291802a74
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now. This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.
Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will2007-04-15T08:49:19ZScott Longscottl@FreeBSD.org2007-04-15T08:49:19Zurn:sha1:2b83592fdcb9e7c201677f3605b9e8738a6b0737
use to synchornize and protect all data objects that are used for that
SIM. Drivers that are not yet MPSAFE register Giant and operate as
usual. RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.
The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.
