* Prepare for future integration between CAM and newbus. xpt_bus_registerScott Long2007-06-171-1/+1
| | | | | | | | | | 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. Notes: svn path=/head/; revision=170872
* Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM willScott Long2007-04-151-1/+2
| | | | | | | | | | | | | | 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. Notes: svn path=/head/; revision=168752

* Mega busdma API commit.Scott Long2003-07-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Reviewed by: tmm, gibbs Notes: svn path=/head/; revision=117126

* Turn on interrupt-entropy harvesting for all/any mass storage devicesMark Murray2001-03-011-1/+1

* Weaken a bogus dependency on <sys/proc.h> in <sys/buf.h> by #ifdef'ingPoul-Henning Kamp2000-10-291-1/+0
| | | | | | | | | | | | | the offending inline function (BUF_KERNPROC) on it being #included already. I'm not sure BUF_KERNPROC() is even the right thing to do or in the right place or implemented the right way (inline vs normal function).

* Convert all users of fldoff() to offsetof(). fldoff() is badPoul-Henning Kamp2000-10-271-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | because it only takes a struct tag which makes it impossible to use unions, typedefs etc. Define __offsetof() in <machine/ansi.h> Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h> Remove myriad of local offsetof() definitions. Remove includes of <stddef.h> in kernel code. NB: Kernelcode should *never* include from /usr/include ! Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API. Deprecate <struct.h> with a warning. The warning turns into an error on 01-12-2000 and the file gets removed entirely on 01-01-2001. Paritials reviews by: various.
