* Remove the wds(4) driver for the WD700 ISA SCSI HBA.John Baldwin2016-08-191-1437/+0
| | | | | | | | | | While this driver does do DMA, it bounce buffers all transactions through a single 64k buffer. It also does not have a manpage. Relnotes: yes Notes: svn path=/head/; revision=304503
* Add locking to wds(4) and mark MPSAFE.John Baldwin2014-11-181-90/+84
| | | | | | | | | | | | - Add per-softc mutex. - Use mutex for CAM SIM lock. - Use bus_*() instead of inb() and outb(). - Use bus_alloc_resource_any() when reasonable. Tested by: no one Notes: svn path=/head/; revision=274680

* Reform the busdma API so that new types may be added without modifyingKonstantin Belousov2013-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.

| | | | | | | | | | | | | | | | | | remaining drivers that haven't been converted have various problems or complexities that will be dealt with later. This list includes: hptrr, hptmv, hpt27xx - device aggregation across multiple parents drm - want to talk to the maintainer first tsec, sec - Openfirmware devices, not sure if changes are warranted fatm - Done except for unused testing code usb - want to talk to the maintainer first ce, cp, ctau, cx - Significant driver changes needed to convey parent info There are also devices tucked into architecture subtrees that I'll leave for the respective maintainers to deal with.

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

| | | | | | | | | | | | | | use to synchornize and protect all data objects that are used for that SIM. Drivers that are not yet MPSAFE register Giant and operate as usual. 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 Long2003-07-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | because it only takes a struct tag which makes it impossible to use unions, typedefs etc. Define __offsetof() in <machine/ansi.h> Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h> Remove myriad of local offsetof() definitions. Remove includes of <stddef.h> in kernel code. NB: Kernelcode should *never* include from /usr/include ! Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API. Deprecate <struct.h> 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.
