* Mega busdma API commit.scottl2003-07-011-0/+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
* Use bioq_flush() to drain a bio queue with a specific error code.phk2003-04-011-1/+0
| | | | | | | | Retain the mistake of not updating the devstat API for now. Spell bioq_disksort() consistently with the remaining bioq_*(). #include <geom/geom_disk.h> where this is more appropriate.
* Centralize the devstat handling for all GEOM disk device driversphk2003-03-081-1/+0
| | | | | | | | in geom_disk.c. As a side effect this makes a lot of #include <sys/devicestat.h> lines not needed and some biofinish() calls can be reduced to biodone() again.

| | | | | | | | | | | | | | | | | | | | | | as module. This also fix's issue kern/45713. Fix - polling was implemented incorrectly for adapter enquiry and adapter flush. (2) Problem: PANIC when unloading driver as module. Fix - device nodes are not destroyed for amr0, and amrd* when driver is unloaded (3) Problem: PANIC from loading driver when 3ware adapter present, error message "Warning "amrd is usurping twed's bmaj" Fix - put #idef freebsd version < 500000 for bmaj -1 -> amrd_cdevsw (4) Problem: warnings in driver when compiling with DAMR_DEBUG param enabled in Makefile Fix - fix the warnings so driver can compile when -Werror is present in Makefile.

* Major update to the AMI MegaRAID driver.msmith2000-08-301-44/+385
| | | | | | | | | | | | | | | | - New support for 40LD firmware found in Series 475 and 471 adapters. - Better support for 8LD firmware adapters - Ioctl passthrough interface for userland utilities. - Improved error handling and queueing. - Several bugfixes (including the 'still open' shutdown bug and closing some small race conditions). - Zone-style command allocator, reducing memory wasted under heavy load conditions. - CAM interface (disabled and not fully working) for SCSI passthrough access to non-disk devices Thanks to AMI for supplying a pile of new adapters and various other help in making this happen.
* Separate the struct bio related stuff out of <sys/buf.h> intophk2000-05-051-1/+1
| | | | | | | | | | | | | | | <sys/bio.h>. <sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall not be made a nested include according to bdes teachings on the subject of nested includes. Diskdrivers and similar stuff below specfs::strategy() should no longer need to include <sys/buf.> unless they need caching of data. Still a few bogus uses of struct buf to track down.

* Update to latest working version.msmith2000-04-011-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add periodic status monitoring routine. Currently just detects lost commands, further functionality pending data from AMI. Add some new commands states; WEDGED (never coming back) and LATE (for when a command that wasmarked as WEDGED comes bacj, - Remove a number of redundant efforts to poll the card for completed commands. This is what interrupt handlers are for. - Limit the maximum number of outstanding I/O transactions. It seems that some controllers report more than they can really handle, and exceding this limit can cause the controller to lock up. - Don't use 'wait' mode for anything where the controller might not be able to generate interrupts. (Keep the 'wait' mode though sa it will become useful when we start taking userspace commands. - Use a similar atomic locking trategy to the Mylex driver to prevent some reentrancy problems. - Correctly calculate the block count for non-whoile-bloch transfers (actually illegal). - Use the dsik device's si_drv1 field instead of b_driver1 in the buf struct to pass the driver identifier arond. - Rewrite amr_start and amr_done() along the lines of the Mylex driver in order to improve robustnes. - Always force the PCI busmaster bit on.
