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

Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.

Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

limitations inherent to the isp1000 on SBus cards.

Frequency default should be '25' for 25MHz, not 25000000.

Through the PITA of endiannness, clock has to be MHz freq << 8. Don't trust NVRAM on SBus cards. Set a default initiator ID sensibly. SBus/ISP now working, what with the change to sbus.c earlier today.

Make sure that if are in fact using 'full SMP', make the interrupt

flags include INTR_MPSAFE. Put the flags in a common place so that both isp_sbus && isp_pci DTRT. In isp_mbxdma setup, drop any locks prior to calling things like bus_dmatag_create. This gets rid of these obnoxious WITNESS messages about 'sleeping with locks held' blah blah blah blah blah.

Remove a couple of debugging lines.
