2b83592fdc Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will
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.

fa9ed86506 The first of 3 major steps to move the CAM layer forward to using
the CAM_NEW_TRAN_CODE that has been in the tree for some years now.

This first step consists solely of adding to or correcting
CAM_NEW_TRAN_CODE pieces in the kernel source tree such
that a both a GENERIC (at least on i386) and a LINT build
with CAM_NEW_TRAN_CODE as an option will compile correctly
and run (at least with some the h/w I have).

After a short settle time, the other pieces (making
CAM_NEW_TRAN_CODE the default and updating libcam
and camcontrol) will be brought in.

This will be an incompatible change in that the size of structures
related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change
in both size and content. However, basic system operation and
basic system utilities work well enough with this change.

9b4fbfe900 Minor tweaks to make it behave better:
o When we're resetting the board, make sure that we error out the pending
  CCBs first.  Otherwise the aha_cmd won't accept further commands, such
  as those that are used to reset the card (AOP_INITIALIZE_MBOX).  This
  appears to cause a cascade failure where no more commands are possible
  to the card.
o Reduce from 10s down to 1s the amount of time we're willing to tolerate
  the card being awol.  This helps the above case.
o Add some error checking to two commands issued in the probe.

I have a dim memory of gibbs@ trying to tell me about this problem a
few years ago, so pointy hat to imp@ for sitting on it so long.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

BUS_DMASYNC_ definitions remain as before.  The does not change the ABI,

25afb89b1c * Add struct resource_list* argument to resource_list_alloc and
resource_list_release. This removes the dependancy on the
  layout of ivars.

* Move set_resource, get_resource and delete_resource from
  isa_if.m to bus_if.m.

* Simplify driver code by providing wrappers to those methods:

     bus_set_resource(dev, type, rid, start, count);
     bus_get_resource(dev, type, rid, startp, countp);
     bus_get_resource_start(dev, type, rid);
     bus_get_resource_count(dev, type, rid);
     bus_delete_resource(dev, type, rid);

* Delete isa_get_rsrc and use bus_get_resource_start instead.

* Fix a stupid typo in isa_alloc_resource reported by Takahashi
  Yoshihiro <nyan@FreeBSD.org>.

* Print a diagnostic message if we can't assign resources to a PnP
  device.

* Change device_print_prettyname() so that it doesn't print
  "(no driver assigned)-1" for anonymous devices.
