- All sources are built in a single object, reducing namespace pollution.
- Kill the ready queue, and handle a busy response to mly_start in callers
rather than deferring the command.
- Improve our interaction with CAM:
- Don't advertise physical channels as SCSI busses by default.
- use the SIM queue freeze capability rather than queueing CDBs internally.
- force bus reprobe at module load time.
- Clean up more resources in mly_free.
- Tidy up debugging levels.
- Tidy up handling of events (mostly just code cleanliness).
- Use explanatory macros for operations on bus/target/channel numbers.
- Convert to a more efficient queueing implementation.
- Don't allocate command buffers on the fly; simply work from a
static pool.
- Add a control device interface, for later use.
- Handle controller overload better as a consequence of the
improved queue implementation.
- Add support for the XPT_GET_TRAN_SETTINGS ccb, and correctly
set the virtual SCSI channels up for multiple outstanding I/Os.
- Update copyrights for 2001.
- Some whitespace fixes to improve readability.
Due to a misunderstanding on my part, previous versions of the
driver were limited to a single outstanding I/O per virtual drive.
Needless to say, this update improves performance substantially.
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.
