| | | | | | | | | | | | | | | in order to get rid of bus space handle and tag in struct sym_hcb. - Remove unused members related to bus addresses in struct sym_hcb. - sym(4) takes care of allocating an instance of struct sym_hcb itself so don't let newbus allocate it as an unused softc also. - Add basic MPSAFE locking. This includes changing the sym(4) CCBs to be allocated up-front instead of on demand as needed. Besides making these allocations more likely to succeed, this also solves the problem of calling bus_dmamap_create(9) with the SIM mutex held. Reviewed by: scottl MFC after: 1 month

* Fix Symbios driver on amd64: Since amd64 has 64 bit pointers but the samese2007-07-201-12/+17
| | | | | | | | | | | | | | | | | | | | 4KB pages as i386, data structures that just fit in one page on i386 (and on 64 bit architectures with 8KB pages) can be distributed over two pages on amd64. This is a porblem in the case of the Symbios driver, since the SCRIPTS engine in the SCSI chip operates on physical addresses and needs physically contiguous memory. Earlier patches used contigmalloc on amd64, but this version replaces part of a structure by a pointer to that data. In order to not introduce an extra indirection for other architectures, the change has been made conditional on __amd64__. Earlier attempts to repair this problem are removed (i.e. the macros that made amd64 use contigmalloc). The fix was submitted by Jan Mikkelsen and modified by me to only affect amd64.

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
