cgd ef767ee388 Replace my personal attribution string ("This product includes software
developed by Christopher G. Demetriou for the NetBSD Project.") with
a generic NetBSD one ("This product includes software developed for the
NetBSD Project.  See http://www.netbsd.org/ for information about NetBSD.")
so that this same set of terms can be used by others if they so desire.
(Eventually i'll be converting more/all of my code.)

cgd cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).
2000-06-04 19:14:14 +00:00
cgd 00b28e7a52 another mod of opportunity: const poison. (cfprint_t should take
const char * as second arg, too, but that's Hard.)  also, convert use
of "(char *)0" to NULL.

augustss 61462c55a3 Get rid of a lot of register declarations.
(Why isn't this done everywhere in the kernel already?)

enami a119cb3677 In the diagnostic check in config_detach, inform the name of parent and
its child who shouldn't be exist.

thorpej 5aa64075cc Add a `config_pending' semaphore to block mounting of the root file system
until all device driver discovery threads have had a chance to do their
work.  This in turn blocks initproc's exec of init(8) until root is
mounted and process start times and CWD info has been fixed up.

Addresses kern/9247.

cgd ccfb44f360 use the old cloning-device cf_unit increment behaviour, if
__BROKEN_CONFIG_UNIT_USAGE is defined.
2000-01-18 07:45:04 +00:00
cgd 71a030cab6 avoid 'marching unit numbers' for cloning devices. (e.g., previously,
if you com* at pcmcia?, and com3 and com4 as pcmcia cards, and removed
and reinserted the card that was com3, it would become com5.  if you then
removed and reinserted com4, it would become com6.  etc.)  Now, instead
of incrementing FSTATE_STAR configuration entries for a driver when
a cloning instance is attached, leave it alone, and scan the device softc
array (starting at the first cloning unit number) for units which are
available for use.  This wastes a tiny bit of time (can require a linear
scan of the softc table for the device), but device attachment should be
relatively infrequent and the number of units of each type of device
is never particularly large anyway.

thorpej 0d7a86c356 - Centralize the declaration and clearing of `cold'.
- Call configure() after setting up proc0.
- Call initclocks() from configure(), after cpu_configure().  Once the
  clocks are running, clear `cold'.  Then run interrupt-driven
  autoconfiguration.

thorpej e8431098fe Add a mechanism to defer configuration of children until interrupts

config_detach().

thorpej ab1b371163 Implement config_detach(), mostly from Chris Demetriou, modified slightly
by Ken Hornstein and myself.

Add flags to struct device, and define one as "active".  Devices are
initially active from config_attach().  Their active state may be changed
via config_activate() and config_deactivate().

These new functions assume that the device being manipulated will recursively
perform the action on its children.

Together, config_deactivate() and config_detach() may be used to implement
interrupt-driven device detachment.  config_deactivate() will take care of
things that need to be performed at interrupt time, and config_detach()
(which must run in a valid thread context) finishes the job, which may
block.

cgd d58173741d kill the last remnants of __BROKEN_INDIRECT_CONFIG. (only the pica port
used it, and it's non-working and apparently slated for replacement.)

of a device until all of its parent's children have been attached.

cgd 66764a1a2f Check for a new definition, __BROKEN_INDIRECT_CONFIG, and if it is _not_
defined:
	define match functions to take a struct cfdata * as their second
	argument, config_search() to take a struct cfdata * as its second
	argument, and config_{root,}search() to return struct cfdata *.

	remove 'cd_indirect' cfdriver element.

	remove config_scan().

	remove config_make_softc() as a seperate function, reintegrating
	its functionality into config_attach().

Ports will define __BROKEN_INDIRECT_CONFIG until their drivers prototypes
are updated to work with the new definitions, and until it is sure that
their indirect-config drivers do not assume that they have a softc
in their match routine.

cgd 1e2b610d5a #ifdef __alpha__, call a machine-dependent function with new device
structure and 'aux', right before ca_attach is called for the
newly-attached device.  This allows the alpha port to do root device
autodetection without modifying every bus and device driver which could
be in the 'boot path.'  In the long run, it may make sense to make
this machine-independent.

cgd fbce6d4468 Make config_found_sm() (and therefore config_found()) and config_rootfound()
return a struct device * of attached device, or NULL if device attach failed,
rather than 1/0 for success/failure, so that code that bus code which needs
to know what the child device is doesn't have to open-code a hacked variant
of config_found().  Make config_attach() return struct device *, rather than
void, to facilitate that.
1996-04-04 06:06:18 +00:00
cgd 8c248b98cc change 'struct device' and 'struct evcnt' lists (alldevs and allevents) to
be TAILQ's.  TAILQ_HEAD's of those structs are now 'struct devicelist' and
'struct evcntlist', respectively.
1996-04-04 00:25:44 +00:00
thorpej 532e997971 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
1996-03-17 00:57:14 +00:00
cgd c6a9e56518 Replace config_found() with config_found_sm(), which adds a cfmatch_t to the
argument list.  This allows easy 'submatching', which will eliminate a fair
bit of slightly tricky duplicated code from various busses.  config_found()
is now a #define in sys/device.h, which invokes config_found_sm().
