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.

* Attempt to fix Symbios driver on amd64. The private memory allocationse2005-01-011-0/+10
| | | | | | | | | | | | | | function provided by the driver limits allocations to the page size, i.e. 4KB on i385 and 8KB on typical 64 bit processors. Since amd64 has 64 bit pointers, but only 4KB pages, an array of pointers that just fits into one page on all the other processors, does require 2 pages on amd64. In order to make this driver useful on amd64, the allocation unit has been increased to 2 pages on amd64 and contigmalloc() is used instead of malloc(). All other processor types are unaffected by this change. This modification has only been compile-tested on amd64, yet, but should just work (FLW).

* Mega busdma API commit.scottl2003-07-011-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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

* Fix:groudier2001-02-111-10/+32
| | | | | | | | | | | | | | | | | - Missing cpu_to_scr() added (endian-ness). Improvement (fix|workaroung??): - Blindly firing a PPR can lead to some messy situations due to various causes or misfeatures, for example: * The 53C1010-[33|66] supports offset 62 in DT mode, but only offset 31 in ST mode. As a result, a PPR(DT, offset 62) responded with PPR(ST, any offset > 31) must be rejected. * A device that doesn't know about PPR should reject it, but may also be confused by this message. When a PPR encounters problems, the driver now patches the goal transfer settings for legacy negotiations to be performed later with the offending target. This give a chance for bad situations to be fixed automagically.
* A couple of chip errata work-arounds refined:groudier2001-01-281-3/+3
| | | | | | | | | | | | | - When used on a 33MHz PCI BUS, the 53C1010-66 revision 0 requires extra clocks to be inserted in data out phase. Revision 1 is fixed. - The 53C1010-33 revision 1 requires internal cycles to be disabled due to possible contentions on IO registers. Revision 2 is fixed. Fix: - The probing of HVD from GPIO3 bit by the driver was reversed. The driver could misprobe the bus mode of a 825 or 875 chip that was not previously initialized (no BIOS for example).
