Prefer new location of pci include files (which have only been in the

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

Merge common XPT_CALC_GEOMETRY functions into a single convenience function.

2003-06-14T22:17:41Z

Devices below may experience a change in geometry. * Due to a bug, aic(4) never used extended geometry. Changes all drives >1G to now use extended translation. * sbp(4) drives exactly 1 GB in size now no longer use extended geometry. * umass(4) drives exactly 1 GB in size now no longer use extended geometry. For all other controllers in this commit, this should be a no-op. Looked over by: scottl

Use bioq_flush() to drain a bio queue with a specific error code.

Retain the mistake of not updating the devstat API for now. Spell bioq_disksort() consistently with the remaining bioq_*(). #include where this is more appropriate.

Centralize the devstat handling for all GEOM disk device drivers

in geom_disk.c. As a side effect this makes a lot of #include lines not needed and some biofinish() calls can be reduced to biodone() again.

branches: Initialize struct cdevsw using C99 sparse initializtion and remove all initializations to default values. This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386. Approved by: re(scottl)

Introduce a new taskqueue that runs completely free of Giant, and in

2003-02-26T03:15:42Z

turns runs its tasks free of Giant too. It is intended that as drivers become locked down, they will move out of the old, Giant-bound taskqueue and into this new one. The old taskqueue has been renamed to taskqueue_swi_giant, and the new one keeps the name taskqueue_swi.
