Mega busdma API commit.

2003-07-01T15:52:06Z

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

Turn on interrupt-entropy harvesting for all/any mass storage devices

I could find. I have no doubt missed a couple. Interrupt entropy harvesting is still conditional on the kern.random.sys.harvest_interrupt sysctl.

Convert all users of fldoff() to offsetof(). fldoff() is bad

because it only takes a struct tag which makes it impossible to use unions, typedefs etc. Define __offsetof() in Define offsetof() in terms of __offsetof() in and Remove myriad of local offsetof() definitions. Remove includes of in kernel code. NB: Kernelcode should *never* include from /usr/include ! Make include to avoid polluting the API. Deprecate 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. Significant brucifications by: bde
