src-test2/sys/dev/mly/mlyio.h, branch stable/7FreeBSD source treehttps://cgit-dev.freebsd.org/src-test2/atom?h=stable%2F72001-07-14T00:12:23ZMerge with latest version of the Mylex 6+ driver.2001-07-14T00:12:23ZMike Smithmsmith@FreeBSD.org2001-07-14T00:12:23Zurn:sha1:822c2e6a945588b913d6805bd4801bcf5acc5f19
- 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.
Major update and bugfix for the 'mly' driver.2001-02-25T22:48:34ZMike Smithmsmith@FreeBSD.org2001-02-25T22:48:34Zurn:sha1:ac91d75193ea1d757c47c8001f20f211a5ce32c0
- 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.
