instead have a call down from the PCMCIA mid-layer to set it. Use this from
pcmcia_function_enable(). (Currently the policy is the same, but this would
allow for more flexibility in deciding which mode to use.)
Now it is safe to hold the socket enabled during attach, so do that. Only
one enable/disable cycle to attach a card now!
* Remove the "expected function" value. This was just causing problems with
multifunction cards. Differentiating the functions is better done by
checking the function type (which we now do in ep and sm).
* Add support for matching CIS strings. This necessitated changing the calling
pattern a little too.
Use this enhanced version rather than driver-specific versions that do the
same thing.
Also, remove the last vestiges of PCMCIA_STR_*.
force it to 0 when a card is detached, possibly disabling the socket in the
process.
Add several new functions:
* pcmcia_config_alloc(pf, cfe)
Tries to allocate all the I/O and memory spaces in a config entry.
* pcmcia_config_free(pf)
Frees all the I/O and memory spaces for the active configuration.
* pcmcia_config_map(pf)
Maps all the allocated I/O and memory spaces for the active configuration.
* pcmcia_config_unmap(pf)
Unmaps all the allocated I/O and memory spaces for the active configuration.
And two higher-level functions:
* pcmcia_function_configure(pf, validator)
Tries to find a CIS config entry that it can allocate the spaces for. Each
entry is verified by calling the "validator" function -- which can also do
card- and driver-specific fixups. If successful, the regions are all mapped.
* pcmcia_function_unconfigure(pf)
Equivalent to calling both pcmcia_config_unmap() and pcmcia_config_free().
Most drivers are expected to use the latter two functions, which will greatly
reduce the amount of crufty code.
underlying implementation DTRT. This has the side effect of causing us to
ignore the INTR and INTRACK bits in the CCR -- but this seems for the best
anyway, since they are not reliably implemented. (I note that Linux doesn't
bother either.)
case (ne@pcmcia) where we were using these to create a subregion, it is better
handled by calling bus_space_subregion().
Now there is a 1:1 mapping between I/O spaces in the config table and windows
mapped in the function. Rework the multifunction mapping code to take
advantage of this by using both I/O base addresses if necessary.
functions taking a pcmcia* device structure.
XXX This is a method of last resort for dealing with stupid/insane cards that
we need to probe harder before we can choose a config entry. It should not be
used by most drivers.
- centralize pcmcia function allocation and free'ing.
- free the cfe too, not just the pf in the multifunction card case.
- don't free pointers while walking the list, because free() will
fill the memory with deadbeef, thus killing list walking.
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
these drivers with a single common function (which supports tables
of variable-sized structures). Things are mostly as they were before:
tables are terminated by entry with NULL name, etc. There's also
the ability to call a driver-specific match function which can be used
to augment the table lookup.
- Deactivate the card on removal and queue a REMOVAL event for the socket's
event thread to finish the detach.
- Queue an INSERTION event for the socket's event thread on insertion.
Implement a few missing infrastructure pieces to support this.
Hot swapping of PCMCIA cards now "works". (Not quite; things like network
devices need changes for their respestive subsystems. These changes are
coming soon...)
both 16bit id values found in card CIS and special value to indicate
that no value found in CIS. Use that special value for the card that
doesn't have id values. Test that value in ne2000_match().
