* Rework the kernel environment subsystem. We now convert the staticMaxime Henrion2002-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | environment needed at boot time to a dynamic subsystem when VM is up. The dynamic kernel environment is protected by an sx lock. This adds some new functions to manipulate the kernel environment : freeenv(), setenv(), unsetenv() and testenv(). freeenv() has to be called after every getenv() when you have finished using the string. testenv() only tests if an environment variable is present, and doesn't require a freeenv() call. setenv() and unsetenv() are self explanatory. The kenv(2) syscall exports these new functionalities to userland, mainly for kenv(1). Reviewed by: peter Notes: svn path=/head/; revision=94936

* Add locking to taskqueues. There is one mutex per task, one mutex perJohn Baldwin2001-10-261-0/+4
| | | | | | | | | | | queue, and a mutex to protect the global list of taskqueues. The only visible change is that a TASK_DESTROY() macro has been added to mirror the TASK_INIT() macro to destroy a task before it is free'd.

(but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process. Sorry john!

* Merge with latest version of the Mylex 6+ driver.Mike Smith2001-07-146-1420/+1318
| | | | | | | | | | | | | | | | | - 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.Mike Smith2001-02-255-354/+599
| | | | | | | | | | | | | | | | | | | | - 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.

* Convert all users of fldoff() to offsetof(). fldoff() is badPoul-Henning Kamp2000-10-271-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
