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

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 Long2003-07-015-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

The flag RR_SHAREABLE has no effect when passed to bus_alloc_resource(dev, SYS_RES_IRQ, ...) in an EISA device context as the eisa_alloc_resource() call (bus_alloc_resource method) now deals with this flag directly, depending on the device ivars. This change does nothing more than move all the 'shared = inb(foo + iobsse)' nonesense to the device probe methods rather than the device attach. Also, print out 'edge' or 'level' in the IRQ announcement message. Reviewed by: dfr Notes: svn path=/head/; revision=49360
